Do I need to drain the gasoline from my chainsaw

Preparing a chainsaw for work

Choice of fuel

Choosing the right gasoline for your chainsaw is an important decision, because the quality of the fuel will affect how good it is and how long it will last. Use gasoline with an octane rating of at least A-92 for chainsaws. Global manufacturers of vehicles claim that their products can run on gasoline A-92 and even A-90, but the quality of fuel in the former Soviet Union leaves much to be desired, so it is better to reinsure and choose high-quality A-92, the more so you need a little fuel.

Choice of oil for your engine

Gasoline chain saws may have a 2 or 4 stroke engine. There are fewer models with a 4-stroke engine, and they are not as widespread. They are lubricated by the oil in the engine crankcase. The lubrication principle is slightly different for 2-stroke engines. Fuel in them goes under the piston to the crank mechanism. This oil needs to be added directly to the engine to lubricate the friction parts.

Oil for a 2-stroke engine must meet certain requirements:

  • The grease must burn extremely well, with practically no ash emissions;
  • The oil must be perfectly soluble in petrol and be well cleaned of impurities that could clog the carburettor passages;
  • the oil must have an anti-corrosion, anti-wear and good lubrication effect.

For use with 2-stroke engines, there are standards for oils: TC-W3 and 2T. TC-W3 oil is used for water-cooled engines, 2T for air-cooled engines. Sometimes you may hear on the internet that chain saw oil is suitable for other units, but this is a mistake. You can only fill a chainsaw with oil that is specifically designed for this category of tool.

Oil to Gasoline Ratios

you need to know the correct proportions of oil and gasoline. The most common is 1:25. One part oil, 40 parts gasoline. If you convert that to milliliters, you get 25 ml of oil for every liter of gasoline.

The world’s leading manufacturers and brands indicate the optimal oil to gasoline ratio in their instructions, as well as the oil brand that is best suited for chainsaws.

Installing and tensioning the chain

The order of installation on the chainsaw is as follows:

  • Install the chain on the tool on a flat surface on which you can lay out small parts without risk of losing them. The tire should be laid out on the surface and the chain next to it.
  • Pull the chain brake lever toward you.
  • Unscrew the retaining nuts and remove the cover that is mounted over the sprocket.
  • Install the sprocket stop with the tooth facing up.
  • Install the busbar on the screws of the engine block.
  • Put the chain on the engine sprocket first, then on the bar.
  • Adjust the position of the tensioning screw on the cover so that it aligns with the lower hole on the bar.
  • Install the cover on the engine block and tighten the securing nuts.
  • After installation is complete, check that there is no play.

Choosing the right tension for the chain is important. It takes you no more than a few minutes to adjust it. Loosen the nuts on the cover, then use the adjustment screw to adjust the tension. The chain should not pull more than 4 to 5 mm off the bar.

Choosing chain oil

You should buy all consumable items from your dealer or an authorized dealer. Here are some tips to help you choose the right oil:

  • Do not buy oil that is visibly leaking or has separation of fractions. It costs less but is of poorer quality.
  • The packaging should contain information about the manufacturer, expiration date, date of issue and other information.
  • If you decide to buy oil from a manufacturer you don’t know, try to find reviews about it online.
  • Do not mix mineral oil and organic oil.

Check regularly that the chain saw is lubricated and that the lubrication system is functioning correctly. You can tell when you’re out of oil by the heavy load on the engine and the wood overheating.

How to Lubricate a Chain?

Your chain saw has a separate oil reservoir for chain lubricant. To find the exact location of the hole, see the manual. As a rule, the size of the tank relates to the gas tank so that the liquid in them ends at about the same time. When filling up your chainsaw, also fill it with chain lubricant. Then you can run out of gasoline without getting distracted by adding lubricant.

Before you switch on the chainsaw, check that the oil is getting to the chain. Point the guide bar at a flat surface and switch on the saw. If you see drops of oil on the surface, the lubrication system is working properly.

First chainsaw start. how to start the tool?

After you’ve followed all the previous steps, start the chain saw and run it in. Because the first time you start the chainsaw the engine will be cold, this is what we will describe:

  • Lay the saw on a flat surface so that the bar and chain don’t touch anything.
  • Pull the chain brake handle away from the front handle by touching it with the brake.
  • Turn the ignition switch to the “on” position.
  • Move choke shutter to the closed position.
  • If your chain saw has a decompression valve, press it to make it easier to start.
  • Move the choke shutter to the start position. If the saw has a combined control, you need to pull the flap lever out of the housing. If it is controlled separately, push the lever and fix it in the intermediate position.
  • Then wrap your left hand around the front handle of the saw and push it against the surface.
  • After that, you must step on the right handle guard.
  • Pull the starter grip with your right hand until the ratchet mechanism engages the starter. At this point there is resistance. Once you have felt it, pull the starter grip toward you.
  • When the engine bursts, you need to open the choke and start the chainsaw again.
  • After starting the motor, accelerate to full throttle and release the throttle lever. The choke shutter closes automatically.

Mistakes when starting the chainsaw for the first time

When starting the chainsaw there are several mistakes that can lead to the chainsaw not starting:

  • When starting the engine, you can skip the moment in which the “grabbing” occurs and continue pulling the starter handle.
  • You might also forget to put the chain opener in the right position.
  • When starting a cold engine, close the choke, and when starting a hot engine, open the choke. This is sometimes forgotten.
  • Another mistake is pumping too much fuel with primer, which causes the chainsaw to fill up.

Don’t forget that your saw may have a faulty spark plug or carburetor.

What to do if the saw has been primed?

  • Unplug the tool.
  • Remove the chain saw cover.
  • Unscrew the spark plug.
  • Pull the starter grip, with the chain saw upside down. This will cause the fuel to come out. If there is a lot of gasoline, it could be a stuck needle, which is rare in practice.
  • Put the spark plug back in, reassemble the chain saw and start again.

Running-in peculiarities of Chinese chain saws

Generally speaking there is no difference between running in brand-name chainsaws and modern Chinese tools. An important rule of thumb is that Chinese chainsaws are quite picky about engine oil. only Chinese formulations should be used for the fuel mixture.

The main reason for this is that Chinese manufacturers produce chainsaws with rather high power. To work properly, they need a boost in the form of special additives which are added to Chinese oils.

Another important rule. to carry out the adjustment of the carburetor of Chinese chainsaws should be in specialized centers, which employ masters with experience in working with such tools.

Fuels and lubricants

When running-in the chainsaw, and during its subsequent operation it is very important to use high-quality fuel and lubricants. Use high-octane gasoline AI-92, 95 when preparing the fuel mixture.

Oleo-Mac Prosint 2T STIHL HP oil Vitals Semisynthetic oil Champion JASO FD oil

It is not recommended to fuel your chainsaw with gasoline that has been stored for more than 2 months. The engine oil is the most important thing to keep in mind. The fuel used should be of good quality and designed for air-cooled two-stroke engines.

The brake pedal and the steering wheel controls can lock the lever in place when you stop the engine.

When running-in the chainsaw, use a fuel mixture prepared in a 1/25 ratio, unless otherwise specified in the instruction manual of the chainsaw.

Fuel mix ratio for chain saw

The same oil is used during the second stage of the running-in period, but the fuel mixture ratio is changed to 1/40. 1/50, depending on the manufacturer’s recommendations and oil characteristics.

need, drain, gasoline, chainsaw

The brake pedal and brake pads should be replaced at least every 30 seconds.

The oiling system should only be filled with oil made specifically for this purpose by a qualified chain lubricant. Do not use diesel oils, waste fluids, hemp or other substitutes as lubricant.

Preparing for storage and preservation of the chain saw

If chain saw is to be stored for a long time, it should be disassembled, cleaned, washed and dried. But first you must drain all the gasoline from the machine. To empty the fuel line, start up the chainsaw with an empty fuel tank. After a few seconds the saw motor will stop on its own.

The lubrication system should also be flushed. The existing oil will deteriorate over the winter. The fact is that all engine lubricant contains additives (friction modifiers, antioxidants, etc) and additives in the bar.). Additives become deactivated and precipitate out if the engine stagnates for a long time, especially if the temperature is low.

This is how you disassemble the chainsaw:

  • Disconnect bar and remove chain. You need to clear all blockages from the bar and the chain. You can even rinse it in kerosene and dry it well. If the chain has had time to blunt since the last sharpening, it is desirable to correct the chain point. Of course, you can leave that job to the spring as well.

The tire and chain should be covered with a thin layer of preservative. Mauve or gunmetal will do. That is you drop some preservative on the rag and rub the parts with it. Store the tire and the chain in oiled paper, preferably parchment paper. But you can also just use ordinary rags.

  • Remove the air inlet filter element from the chain saw. Remove the coarse strainers from the fuel tank and lubrication system neck. The coarse filters are simply rinsed and dried. If there is a fine fuel filter, it is better to replace it in the spring with a completely new analogue.

Separate attention should be paid to the air filter. Air inlet filter element should be unplugged and well cleaned. If the filter has already worked for 2-3 seasons, it makes sense simply to put a new air filter element in the spring.

  • Unscrew the spark plug and clean the spark plug head, especially the electrode from the deposit. The user should monitor the spark plug service life. If the chainsaw is used a lot, the spark plug usually spends 2 or 3 seasons. But if you seldom use the chain saw, it will last 4-5 seasons on average.

If the chainsaw is expected to perform well, the spark plug should be changed every 2 years!

  • Add 5 (ml) of engine oil to the spark plug well and crank the crankshaft 2-3 turns. Use the chain sprocket to crank the crankshaft. This method will allow the engine lubricant to create a thin protective layer in the cylinder.

As mentioned above, the lubricant tends to tan and dry out when stagnant. For this reason the user should manually crank the chain saw’s crankshaft once a month. If the user knows that he will not have time or possibility to work out the power pack regularly, it is better not to pour oil into the cylinder.

Don’t forget to replace the spark plug after cleaning it!

  • Clean and lubricate the chain tensioner.
  • Pack up all disconnected parts and the power unit itself. To be on the safe side, it is best to store the saw in a sturdy cardboard box. It is not necessary to make the container airtight, because without air exchange, moisture can accumulate in the box.

How to use a chainsaw in winter

You may need your chainsaw in the winter as well. In this case, the user needs to know how to make the chain saw work as safely and reliably as possible.

The main problem with using a chain saw in the winter is the low ambient temperature. In the cold, gasoline is less volatile, which is reflected in the carburetor. To start the chainsaw and warm it up to a comfortable temperature very often it is necessary to use the forced fuel intake.

If you don’t know, the spark plugs are flooded with petrol when the engine is pumped manually. In this case, the plugs quickly fouled, they need to be cleaned almost after every use.

You have to be prepared for the lubrication system not to be 100 percent effective. The chainsaw oil gets thick in a cold weather. Add a little gasoline to the oil to keep it from getting too viscous.

After you have completed all the work the chain saw should be put into storage in accordance with the above-described scheme.

Does an electric chainsaw need to be canned in winter?

Gasoline-powered chainsaws differ from electric chainsaws only by the type of drive system. Electric saws are a little luckier, because they do not use liquid fuel, they have no spark plugs, no filters, no carburetor. But electric chainsaws also need to be preserved for the winter. Of course, electric chainsaws have a simplified approach to storage.

You just have to detach the bar and chain, clean them and lubricate them with a preservative. It’s the same as with our gasoline-powered counterparts. If the chain has blunted in time, correct the sharp edges on the teeth.

In addition, the chain tensioner should be cleaned and lubricated. The oil in the lubrication system should be drained. In the spring, you’ll need to fill the system with new, fresh oil.

How to fight against moisture

The main negative factor when storing a chainsaw in winter is an increased level of humidity. Moisture tends to condense on metal and other surfaces and significantly speeds up corrosion processes.

If a chainsaw is kept in a garage in winter, it should be heated periodically. Heat speeds up the evaporation of moisture. But the best results are ensured by so-called dehumidifiers (dehumidifiers). These are adsorbents that pull in moisture and hold it reliably.

There are various types of dehydrators. The most advanced are electric models. The average household dehydrator collects up to 1-2 liters of water per day. To save costs, the dehumidifier can be activated periodically, at times of rain or slushy weather.

If you are sorry to waste energy on hooking up a powerful dehydrator, you can do with the old-fashioned method. We are talking about silica gel sachets. You just need to throw in a three or two standard 10 (g) sachets of desiccant in the box with the packed chainsaw.

How to store a chainsaw in winter

This is probably one of the few tools for which there is work even in the cold season. But the chainsaw’s operating temperature range is usually limited by the fact that it contains frost-resistant parts, gasoline and oil. If the manufacturer guarantees operation at.10°C, this is a very good indicator and such a saw can be used almost all year round. If you leave the cottage for a long time, then take care of proper preservation.

“The heart of any chainsaw is a carburetor-type, single-cylinder, two-stroke engine. Another important element is the chain. It’s these two items that take care of most of the preservation recommendations:

  • First of all, drain the remaining fuel from the tank, carburetor and oil to lubricate the chain. To get the gasoline out completely you can run it idle and wait until the gasoline runs out. Afterward, wipe the gas tank dry so it doesn’t start rusting. This is an option for long-term preservation, at least 3 months. But there is a second option for those who log or do other winter work. In this case it is recommended to fill the tank to the brim with high-quality gasoline and leave it in this state for storage. If you need to cut down a tree in a hurry, that’s great. you’ve got all the machinery you need at your fingertips. But remember, gasoline, which in 2-3 frosty winter weeks will start to resemble a kisel in consistency, can disable even a first-class engine;
  • Using a wire dipstick or a homemade nozzle, remove the tip filters from the fuel and oil tanks. flush and install them after drying or replace them with new ones if necessary. Do the same with the air filter;
  • Remove saw chain and guide bar and free them of sawdust, wood dust and dirt;
  • Remove the clutch cover, rinse it thoroughly under running warm water and let it dry. Lubricate the worm gear and the screw of the side chain tensioning system;
  • Remove the spark plug and clean off the soot and fuel residue. Pour 5-7 ml of engine oil into the spark plug hole and turn the crankshaft 3-4 turns to distribute the oil over the crankarms and piston-cylinder group. Leave the piston at its highest point (raised). After that, put the spark plug back in place, but do not put on the ignition terminal;
  • Coat the guide bar and chain with protective lubricant and store it wrapped in a piece of paper or cloth soaked in oil;
  • Pack the tool and hide the removed parts in a dry, dark and dustless place.

About once a month, rotate the crankshaft to regrease the grease in the connecting rods and cylinders and pistons.

If your saw is electric all you need to conserve it is to lubricate the bar and chain with a barrier fluid.

Using a chainsaw during the cold season: Highlights

There is always a task for the chainsaw in the house, so sending it on a “winter vacation” is not always rational. In such cases the tool is not completely stored, i.e.Е. Without a complete disassembly.

If you plan to use the chain saw in the winter, store it and the fuel mix in a well-ventilated, dry, warm, at the very least unheated place that is protected from outside influences. ,

Before you start, check that the fuel has a sufficient temperature for ignition and that the oil in the lubricating system is of normal viscosity. Some chainsaw models are equipped with a system that supplies hot air to the carburetor from the cylinder cooling ribs, reducing the risk of the air filter freezing and preventing condensation on the carburetor.

Check the lubrication system before you start work

Before starting in the cold, keep the throttle closed and check the lubrication and tension of the chain. As soon as the job is done, the tool must not be brought into the room immediately. This is guaranteed to cause condensation, so you will have to take it off, disassemble and clean it.

How to store the lawnmower in winter

This machine is sent to a “deserved rest” in autumn, and is extracted closer to the end of spring. Because of such a long “downtime”, the requirements for the preservation of lawn mowers are very high.

Gasoline lawnmower

The gasoline lawnmower’s main elements are the engine and the cutting parts. It is to these that maximum attention must be given:

  • The first condition for proper storage is a room with humidity of no more than 70% and no sudden changes in temperature that increase the humidity;
  • If you have been working with your mower a lot, grass particles and moisture can get on the internal parts of the machine. So be sure to wash, clean, and dry the blades and other parts within reach. Remove grass residue from the body, exhaust pipe, engine cooling radiators, etc.д.;
  • Opinions are divided on the fuel. Some dacha owners empty the leftovers and wipe the tank dry to prevent condensation from forming over winter. The other half, on the other hand, fill the tank to the brim and leave it like that for the winter. However, in this case, poor-quality gasoline can give sediment, which will make it difficult to start the engine in the spring. It is still easier to remove fluid residue from the carburetor than to clean it of plaque and sludge, so we recommend the first option;
  • Check the cutting knife for need of repair and sharpening. In any case, take it out and sharpen it for the winter. If necessary, consult a professional;
  • The oil level should be in accordance with the recommendations in the instruction manual (for 4-stroke engines);
  • Store the mower so that its wheels do not touch the floor, either suspended or on stands.

Electric lawnmower

Before winterizing the machine, check all connections for intactness and examine them for oxidation and rust. Otherwise, the electric motor does not require any special preservation measures. Recharge the battery for the winter, clean the body, deck and blades of grass and sharpen them if necessary.

Features of chainsaw

A chainsaw is a hand chain saw with a cutting attachment that is powered by a carburetor engine.

This is usually a single-cylinder two-stroke motor.

This design is simple, economical and can be operated in any position.

The saw’s design, in addition to the motor, includes:

  • carburetor;
  • bar;
  • cutting organ (chain);
  • starter;
  • The clutch is of the centrifugal type;
  • ignition, fuel system, air filters;
  • chain lubrication system;
  • muffler;
  • handles.

The engine can be located vertically (heavy-duty professional models) or horizontally (lightweight household tools). Heavy saws are used for felling and bucking logs, they have large frame sizes. Light saws are used for limbing or cutting firewood, and are commonly used by homeowners, farmers, gardeners, etc.п.

The construction of the tool is simple, which is a guarantee of high durability and reliability. The engine shaft drives the drive sprocket through the clutch, which moves the chain around the bar with the drive sprocket. The two-stroke engine does not need a camshaft, valve system and other elements, which also contributes to the reliability of the design.

See also  How to Determine the Chainsaw Chain Step

The centrifugal clutch has two friction clutches that are pressed together at low RPM and, when the RPM is increased, centrifugal force pushes them to the outside of the clutch and sets the drive sprocket in motion. Engine power determines the chain type. the more powerful the saw, the greater the chain pitch (the distance between the teeth which determines the cutting performance of the tool).

Important! Using a chain incompatible with the engine will result in a loss of performance.

What kind of fuel to use for the chainsaw??

Choosing the right fuel is a critical and important decision. The only correct approach to its solution. a careful study of the user manual, which specifies the type and brand of fuel, the proportions of mixing gasoline and oil, as well as reflect all the features of the tool. Modern standards require the use of high-octane refined fuel and special types of engine oil.

Choice of gasoline

Many people wonder what kind of gasoline works best on a chainsaw. Most models require clean, high-quality fuel with an octane rating no higher than 90. Sometimes you can find recommendations on the net to mix 92 or 93 gasoline with 95 to increase its efficiency. This should not be done in any case, because higher-octane brands are often counterfeited, and no one will dilute the brands of A92 or AI92.

Therefore, choosing what kind of gasoline to pour into a chainsaw in the conditions of the domestic market, it is recommended to use this fuel. It is necessary to ensure that the gasoline is fresh enough, because during prolonged storage it starts to produce resins and other elements that degrade the quality. The manufacturers recommend using:

  • STIHL STIHL-180 chain saws are ideally fuelled with petrol grade A90 or higher;
  • STIHL 250. runs on gasoline with an octane rating of at least 90. You should not use fuel with m ethanol, exceeding 10%;
  • Partner. only unleaded gasoline with a minimum octane rating of 90 should be used;
  • Husqvarna. gasoline with at least 90 octane number, pure fuel or with tetraethyl lead added is acceptable. Engines with a catalytic converter require a fuel-oil mix of unleaded gasoline.

As a rule, the owners of such tools use gasoline AI92, which fully meets the requirements of the manufacturers. However, most home-made chainsaws can use A72 or A80 gasoline. It should also be remembered that malfunctioning of the chain saw due to low-quality fuel is not covered by the warranty.

Choice of oil

Your chain saw uses two types of oil. engine oil and chain oil (adhesive oil). Not to be confused, as their tasks are different. Any gear oil can be used to lubricate the chain, although manufacturers always recommend the use of materials of the same name. The requirements for engine oil are stricter. All the manufacturers are unanimous on this point. you should use oil from the same company that made the saw.

Two-stroke engines do not have a lubrication system, which is replaced by the presence of some material in the fuel. Carburetor injects a fuel-oil mist that incidentally lubricates all parts. After that, the residue burns off in the cylinder. Any two-stroke oil can be used if the instructions are not specific.

Manufacturers recommend it for different tool models:

  • For the STIHL 180 chain saw, the best choice is STIHL HP, HP SUPER or HP ULTRA;
  • STIHL 250. the correct oil to use is STIHL HP, HP SUPER or HP ULTRA, STIHL HP ULTRA shows the greatest efficiency;
  • Partner. any two-stroke oil. Do not use automotive or marine oil, it will cause the engine to fail;
  • Husqvarna. the manufacturer recommends Husqvarna two-stroke oil. Do not use oil for four-stroke engines, or for water-cooled two-stroke engines.

Important! Not all oils are commercially available in Russia, so sometimes it is necessary to change to other, available types. The use of synthetic, high-quality materials is considered the most successful.

The most common problems with the chain

How to Adjust the Chain Oil Flow in a Chainsaw?

If the oil flow to the chain is not adjusted correctly, the chain may overheat (insufficient flow) or cause increased oil consumption and oil contamination of the wood (too much flow). So chain saw oil flow adjustment is very important, because it affects both oil consumption and chain saw performance.

How oil is applied to the chainsaw chain depends on the position of the oil pump plunger adjustment screw. Factory setting has the screw set in the middle position. To decrease the oil flow, turn it to o, to increase it, turn it to o.

Mineral oils are inexpensive, so they are most commonly used. Synthetic oils should be used if there are large fluctuations in temperature, they do not produce soot, and they have additives that are useful for dynamic components.

Product is considered the highest quality. Lukoil machine oil is in second place.

  • Low consumption.
  • Maintains quality.
  • The ability to retain its technological qualities for a long time.
  • Can work under extreme conditions.
  • No toxins.
  • Minimal fouling.

Many professional tools use a lubricant that is made according to API-TB technology (USA). Also popular with products that are made according to JASO-FB (Japan).

Do not use the product if the package says it is for four-stroke engines. If you do not know the oil manufacturer, it is better not to use it.

What kind of gasoline do you use for your chainsaw??

It is acceptable to mix oils from different brand manufacturers with similar characteristics. Mineral and synthetic oils are not compatible with each other. The best oil for domestic chainsaws is considered “Standard”, for professional machines the technical fluid “Ultra” is optimal.

Some oils can successfully substitute each other. For example, substances produced by Husqvarna and STIHL. Lubricant for scooter or motorboat engines is not suitable for chain saws, because the oil quality is low. If you do not maintain the proportions of oil and gasoline, the tool will quickly fail due to the abundant formation of carbon deposits.

If the power of the tool up to 1500 watts, 100 grams of machine oil per 4 liters of fuel is added. If the power is higher, the proportion 1:50 is used, i.e. 100 ml of product per five liters. Recommendations of manufacturers vary greatly, it is recommended to get acquainted with such information in the first place.

The filter is not cleaned in time or replaced

Air filter must be cleaned after each use or at least once a week. If the filter is felt, you can see all the sediment on it. It can be washed. And if the mesh-plastic one, it is in principle easy to blow out.

Fuel filters, too, need to be changed periodically, just like on a car. They also need to be checked periodically. If the filter has become a dirty gray color from dirt, it needs to be replaced, otherwise the fuel will get stuck in it.

Failure to observe safety precautions

It is necessary to use chain saw in protective outfit. helmet, special mask and gloves. If you cut wood in the woods, a helmet should protect your head. Mask protects against sawdust or debris in face and eyes. You need gloves to protect your hands from splinters.

The most important thing with any tool is to use it properly and take good care of it. Then the indispensable garden gasoline tool will last a long time and recoup its cost. Safety should not be neglected, because it is so important for life and health.
