Patriot Petrol Cutter Won’T Start

Patriot Chainsaw Range Why Patriot Chainsaws Are in Great Demand. How to choose the right saw for your home. Review of popular tools. Real reviews.

Garden Home range

In 1999, when Patriot chainsaws appeared on the Russian market, they were sold under the Garden Home brand. The manufacturer could not be under his own brand. Garden Home has become a kind of guide for Patriot to the Russian market. In 2013, Patriot was able to sell tools under its own brand, after which the phrase Garden Home completely disappeared from the name of chainsaws.

Often we receive questions from our visitors asking them to explain how Garden Home chainsaws differ from Patriot. The answer is nothing! All of this is done for marketing and legal reasons.

Semi-professional chainsaw Patriot PT 5220

The word semi-professional does not mean that you can use it 8 hours a day, 7 days a week. This only means that the chainsaw is powerful and from time to time it can safely cut trees of large diameters. Than 40-45 cm.

The chainsaw is equipped with a 2.5 kW (3.4 hp) engine with a volume of 52 cubic meters. See Also, like the 4518 has an EasyStart system for easy starting. The manufacturer claims that this system reduces load during startup by 60%. Time has shown, for all its power, the engine has a reduced resource and high fuel consumption.

The chainsaw is equipped with a 20 ” headset as standard. The chain is of high quality, keeps sharpening for a long time.

Weak side weight. 9 kg without fuel, oil and headset! You can’t work with such a weight for a long time, your hands will get tired quickly.

Earlier, a detailed review of the Patriot PT 5220 chainsaw has already been published on our website.

Patriot PT 554 PRO

The tire is 50 cm long and the motor power is 2.5 kW, so it can be effectively used for household needs. Suitable for harvesting firewood, cutting branches, small trees and other small jobs. One of the serious drawbacks is heavy, weighs 5.1 kg. Appetite moderate for this engine power.

Design features

Patriot chainsaws are not equipped with such rich equipment as, for example, Stihl or Husqvarna saws. After all, this is just a good Chinese man put on the conveyor. However, saws have a number of serious advantages over their competitors from the Middle Kingdom:

• On the piston of all saws, without exception, two oil scraper, compression rings are installed;
• Chrome-plated cylinder working surface;
• The connecting rod and piston group (SHPG) are made of forged steel.

These 3 points give Patriot chainsaws a reliable engine that dramatically increases tool life.

It is worth noting the unification of Patriot chainsaws. Many users note the excellent interchangeability of spare parts. From tires and chains, to carburetors and engine components.

Patriot PT 555

Of the advantages, the engine power is 3 horsepower. Weight 7 kg. The chainsaw is really powerful, it can cut large trees, it is positioned by the manufacturer as a professional one, although it is not. Engine parts are not designed for continuous operation, the chainsaw is suitable for those who need to cut something massive from time to time.

Patriot Chainsaw Range

Over the past years, Patriot chainsaws have been very popular among the population of our country. All this thanks to the good price-performance ratio. Chainsaws are not whimsical in operation, the build quality is good. Spare parts are not expensive and freely available. Patriot saws are considered an excellent option for a summer cottage, the lineup includes more than a dozen models. As part of the article, we will consider the most popular tools.

The gasoline cutter won’t start after winter

In such cases, the unit must be serviced. Remove the fuel system, including filters (air, fuel), disassemble the carburetor, clean and rinse each unit. Blow out the filters with air. Pay attention to fuel quality and octane number.

It should be borne in mind that products of such well-known companies as STIHL, Husgvarna and other brands will not run on cheap gasoline with a low octane number.
Suitable fuel for them is from the AI ​​92 brand and above from car refueling stations and then from well-recommended ones, since there is also bad gasoline at refueling stations. The use of high-octane and high-quality gasoline will determine how long the brushcutter will be used and how long it will last.

It is necessary to take into account one more fact that with a long storage of a diluted fuel mixture, its working qualities fall, which also leads to consequences in which the petrol cutter will not start. Therefore, it should be diluted in portions, that is, the amount of the mixture that is produced at a time.
The operating instructions clearly describe and explain the mixing ratio of gasoline and oil. Strict observance of the correct proportions will at least save you from several questions about why the petrol cutter will not start and what to do in such cases.

The benzokos starts up and stalls. What to do?

1. There is a spark, and everything seems to be normal, but the petrol cutter will not start, in such cases, you should check the air access valve to the fuel tank. A clogged valve leads to the creation of a vacuum in the tank, in which the carburetor does not receive enough gasoline, so the petrol brush will start, but then stall. To exclude this reason, you need to clean the valve and try to start a petrol cutter with a tank cap that is not completely twisted.
2. If the brushcutter does not start at the same time, you should remove and clean the fuel filter, as well as check all the carburetor parts, and then try to start. The petrol cutter will not start again, the air filter is disconnected, try to start without it, if the mower starts up, the reason is in the air filter, replace it.

The benzokos does not start on a cold

When starting a cold engine, it is not recommended to press the gas. Tilting the brushcutter so that the air filter is on top, press the fuel suction button 5-6 times, set the function switch lever to the start position, pull the starter cord several times until the engine starts. After a few seconds of running the motor, turn off the starting system.

The petrol cutter will not start, the spark is gone

The loss of a spark entails checking the contacts and the correctness of the gap between them, the conducting wires to the candle and the candle itself.
The way to check the spark is to unscrew the candle, connect a wire to it, put the candle sideways to the engine casing and pull the starter several times as if starting a petrol cutter, while looking at the coal and the contact of the candle, a spark should run between them.
If there is no spark, take a new candle, follow the same procedure, if the spark cannot be traced, then there is a problem in the wire or contacts, it is better to replace them.

The petrol cutter will not start or will start, but stalls. What is the reason?

To understand this, you need to know the principle of operation of the unit as a whole. It also happens that, just bought, a new saw does not start, and it starts running around the service centers, in such cases it is recommended:

Carefully read the instruction manual;
to study in detail the method of the first start-up and running-in of petrol cutters;
try to understand how the product works;
how gasoline is pumped up and so on.

Reasons for malfunction of petrol cutters:

The quality of gasoline is poor;
incorrect proportion of gasoline and oil;
clogging of the fine filter;
the spark was gone.

The benzokos does not start when hot

If the brushcutter was recently in operation and has not yet had time to cool down but does not want to start, press the gas trigger, pull the starter cord sharply several times until the engine starts and only then the gas trigger is released. If enough time has passed and the brushcutter has managed to cool down, then it is necessary to start it as if it were cold.
We determine the availability of fuel and its supply.

First you need to make sure that there is a fuel mixture in the tank of a chainsaw that does not want to start, and it regularly enters the carburetor. With a full tank, we check how the mixture is fed through the gas line. Disconnect the fuel system pipe from the carburetor and try to pump it up. In the case of a complete order, when pumping, gasoline will be supplied in jerks in accordance with the standards set by the manufacturer. Poor or no fuel supply can result from:

• The fuel supply channel is clogged;
• Clogged fuel filter.

Often the reason for a poor start of the chainsaw can be a tank that is too full. In this case, you should pay attention to the presence of smudges under the saw case cover. If present, see the connection of the gasoline feed pipe to the carburetor. Most often, it is squeezed out by pressure when the tank cap is screwed on, filled up to the very neck, which prevents the engine from starting.

The quality of the fuel mixture can also be one of the reasons why the chainsaw does not start. If, after completing the work, the remaining gasoline is not drained, and the tool is left for long-term storage (more than 2 weeks), then the processes of gum formation and polymerization of components will begin to occur inside the tank. What can cause carbon deposits on the piston, rings and cylinder liner. Therefore, always prepare the mixture only in the required amount before work.

Checking the spark on the spark plug and eliminating the cause.

The first step in looking for reasons why your gasoline saw won’t start is to check the spark on the spark plug. There are many factors that affect the performance of this element. However, the main ones at the initial stage of instrument troubleshooting are:

• Incorrect carburetor adjustment;
• The presence of more than it should be, the amount of oil in gasoline;
• Clogged air filter.

All of them contribute to the formation of carbon deposits on the spark plug electrodes. In 50 cases out of 100, the saws do not start on a cold one due to the absence of a spark due to carbon deposits on the electrodes and their corrosion. As a result, the gap either decreases or increases.

Checking the spark plug with an idle chainsaw

It is quite easy to check for a spark. This will require:

• Remove the tip of the high-voltage wire;
• Unscrew the candle;
• Put the tip back on;
• Lean the candle with a skirt against the cylinder;
• Start with a starter.

If a good spark is observed between the electrodes at the time the chainsaw engine starts, then everything is in order with the ignition unit. If it is not there, then it is worth cleaning the element itself and checking the gap of the electrodes. If necessary, use a special probe to adjust the distance between the contacts.

There may be no spark on the spark plug for other reasons. Of the main faults affecting the poor start of the chainsaw and the unstable operation of the internal combustion engine at idle, from which the tool can stall, the following can be attributed:

• Overflow of the spark plug channel with fuel;
• Lack of contact between the high-voltage cradle and the tip of the candle;
• Failure of the ignition unit.

How to start a cold chainsaw if the candle channel is constantly flooding with gasoline? To eliminate the problem while starting the tool, you can use the following algorithm:

• Unscrew the candle with a special key;
• Wipe it with a clean and dry cloth;
• Dry for 2030 minutes;
• Remove carbon deposits with a file and adjust the gap between the electrodes;
• Drain the remaining fuel from the spark plug channel and dry it;
• Collect everything and try to start the mechanism.

If there is no spark with poor contact of the high-voltage cradle with the spark plug tip, check the connection. The check can be done using a conventional tester. If a defect is found and its elimination, the chainsaw should start without any problems.

If the check showed that the contact is reliable, and the saw will not start further, look for the cause in the ignition unit. As a rule, a faulty unit cannot be repaired or restored. It will require a complete replacement.

Checking the condition of the fuel and air filters.

If everything is in order with the fuel quality, the chainsaw engine may not start due to clogged fuel and air filters. To diagnose these elements, it will be necessary to perform a number of manipulations associated with their dismantling.

For the fuel filter:

1. Disconnect the gasoline supply channel from the carburetor;
2. Pump up fuel.

If there is little or no pressure in the pipe, disconnect the filter. Before this, free the tank from the mixture and remove the filter element itself. Dismantling is done with a wire hook. A clogged replacement cartridge that causes a poor starting of the chainsaw engine can be cleaned, but it is best to replace it with a new one. When operating the tool in dusty conditions, it should be cleaned on a regular basis.

A clogged air filter can cause the chainsaw engine to run erratically, making it stalling or difficult to start. Dust and dirt deposited on the adsorbent material impedes the flow of air into the system, making the fuel mixture so rich that starting the tool will sometimes be difficult.

Checking the air filter is one of the first steps in finding the cause of a poor start.

Care must be taken when removing the air filter, as dust accumulated on the surface of the saw during operation can enter the carburetor. And this is fraught with more expensive repairs. After detaching the cartridge, thoroughly clean it from the accumulated dirt and rinse it with the addition of detergent. Dry the element and place it in place just as carefully.

Identification and elimination of obvious malfunctions of the chainsaw.

To determine the reason why the chainsaw does not start or stalls when starting, it is necessary to troubleshoot the tool. The essence of the procedure is to consistently inspect the condition and operation of the main working elements of the saw motor. At this stage, we check:

• Spark plug present;
• Fuel supply;
• Filter status;
• The operation of the breather of the stalling unit built into the fuel cap;
• Functioning of the outlet channel.

Checking the outlet of the chainsaw.

One of the reasons that a chainsaw does not start well may be a clogged exhaust channel or its muffler. At the same time, a drop in power is noted in the process of sawing sawn timber and logs. This is most often due to resinous deposits on the spark arrestor or muffler channel, which are formed during the combustion of a poor-quality mixture of gasoline and oil, which impede the removal of exhaust gases.

Resonator clogged with carbon deposits can cause poor starting of the gasoline saw.

Eliminate the reason for the poor start of the chainsaw, in this case, you can remove the accumulated combustion products. To do this, perform a number of manipulations:

• Remove the muffler by unscrewing the screws;
• Remove the cooling panel and gasket;
• Remove the spark arrester;
• Disassemble the resonator housing;
• Wash all elements from carbon deposits with detergent;
• Let them dry completely;
• Collect everything in reverse order;

Finding reasons why your chainsaw won’t start

Amateur and professional chainsaws are complex devices. The service life of their two-stroke engines, components and assemblies has its limitations. For this reason, quite reliable and expensive tools, along with cheap Chinese units, periodically fail and refuse to start. The situation when the chainsaw does not start or stalls is not very pleasant and sometimes confuses the user. How to identify and correct a malfunction by returning the instrument to work.

• Identification and elimination of obvious malfunctions of the chainsaw.
• Checking the spark on the spark plug and eliminating the cause.
• We determine the availability of fuel and its supply.
• Checking the condition of the fuel and air filters.
• Checking the breather and cleaning it.
• Checking the outlet of the chainsaw.
• What if the chainsaw won’t start further?

Complex reasons for the failure of petrol cutters

If the step-by-step troubleshooting algorithm does not work, and your scythe still does not start or stalls, it is worth inspecting the carburetor and the engine itself. A clogged carburetor can be one of the reasons for erratic tool performance. There are three main problems here:

• Clogged ducts or nozzles. All this is cleaned by special washes or blown by a powerful jet of compressed air from the compressor. Do not use needles and wires, as the bore may be damaged;
• Worn carburetor gasket. Exit replacement of a failed gasket;
• Violation of tightness. To check this indicator, you can use an ordinary household tonometer, replacing it with a suitable pressure gauge. Watch the readings: if they do not change everything is fine, but if the pressure starts to drop, then some part of the carburetor is faulty. We’ll have to find it and replace it with a new one.

If everything is in order with the carburetor, then the petrol trimmer may not start due to wear of the piston group. If chips, scratches or scuffs are found, the piston or cylinder should be replaced. Piston rings are subject to mandatory checks. A small backlash of the piston when rocking the connecting rod indicates that it is time to change the rings. It is best to entrust this procedure to the specialists of the service center.

Why the petrol cutter won’t start troubleshooting

Caring for the personal plot, summer residents periodically encounter the fact that the petrol cutter does not start. There are many reasons for tool failure. For the correct diagnosis of the problem, the owner of a useful unit in the country needs to know the device and the principle of operation of its individual parts.

• How to start diagnostics of brushcutters
• Checking the fuel mixture
• We carry out diagnostics of a candle and a candle channel
• Diagnostics of filters for petrol cutters
• Breather and exhaust port
• Complex reasons for the failure of petrol cutters
• Rules for the operation and storage of petrol cutters

We carry out diagnostics of a candle and a candle channel

If the quality of the fuel mixture is not in doubt, and the brushcutter stalls when starting, then a flooded candle may be the cause. Here, for repairs, an ordinary candle wrench is suitable (every motorist probably has) and a spare candle.

• We unscrew the candle and wipe it;
• Dry it thoroughly (do not ignite);
• We drain the excess fuel in the chamber through the spark plug hole and dry it;
• We clean the old candle from carbon deposits using a file or a lady’s file;
• We expose a gap with a distance of 1 mm (you can check with any coin);
• We put everything back in place and try to start the trimmer.

If the candle is working, the socket where it is located is completely dry, and the petrol cutter does not want to start, lubricate the threaded connection with gasoline. It should be slightly damp. No matter how wonderful a spark the candle may give out, there is simply nothing to ignite in a dry chamber.

If the trimmer motor still does not start, you should exclude such a reason as the absence of a spark due to poor contact between the spark plugs and the high-voltage wire. If the connection is good and there is still no spark, most likely your ignition unit has flown. Here it will not be possible to do without a master, since the part is not repaired, but sold as a single unit.

Checking the fuel mixture

Before starting the engine of the gasoline streamer, check the presence and quality of the fuel mixture. Do not save, do not be greedy and do not be clever in this matter. Repair or replacement of the piston group will cost you too much (sometimes up to 70% of the cost of a new tool). Prepare the oil-fuel mixture strictly according to the instructions. Calculate its amount based on real needs. Excess gasoline left over after work loses its quality over time.

How to start diagnostics of brushcutters

If the brushcutter does not start or immediately stalls after starting, it is necessary to sequentially check all the main components and assemblies. The verification algorithm is as follows:

• Fuel tank (fuel quality);
• Candle and candle channel;
• Air filter;
• Fuel filter;
• Breather;
• Outlet channel.

These nodes are most often the source of major problems that can be eliminated after a thorough inspection.

Diagnostics of filters for petrol cutters

Another reason why the gasoline scythe stalls is the air filter. To eliminate it, try removing the filter and starting the trimmer without it. If possible, then you will have to change the air filter to a new one, or at least blow through and thoroughly clean the old one.

The petrol trimmer may not start if the fuel filter is dirty. This is the next step in our algorithm. Here we check the condition of the filter element and, if necessary, replace it with a new one. When replacing, try not to leave the suction pipe completely without a filter, this is prohibited by any operating instructions. Haste can turn into repairing the engine piston group.
