Why Trimmer Doesn't Develop Turnover

Original Italian-made Oleo-Mac gasoline and electric lawn mowers are considered reliable mowing tools that are valued for impeccable build quality and low-wear sharp knives for the cutting system. But, like every machine subjected to intense, unnormal load, the Italian wheeled lawn mower, especially the Oleo-Mac gas mower, needs a scheduled service.

Design Features of the Oleo-Mac Lawn Mower

Oleo-Mac Rotary Wheel Petrol Lawn Mowers consist of:

An aluminum or steel case, inside and outside of which key components of the equipment are located, including a casing with an internal combustion engine (ICE) with a manual or electric starter, a carburetor and a fuel tank.
Folding handle for maneuvering.
4 wheels (may be of the same diameter, but the front may be smaller than the rear)
Aerodynamic deck with a cutting knife system assembly located at the bottom of the case. The cutting system is a steel knife horizontally mounted and mounted on the ICE shaft. With a high speed of rotation, the knife successfully cuts grass, weeds with thick stems.
Grass catcher made of plastic, fabric or a combination plastic-fabric container for collecting grass.
System of the central lever or independent wheel multistage regulation of height of a cut.
Optionally, there may be a mulching plug, expanding the capabilities of the lawn mower by another mode.

Performing the same task, the Oleo-Mac electric lawnmower looks similar in appearance, but has a more compact design due to a lighter electric motor, lack of a fuel and oil tank. Wired power. a power cord for connecting to a 220 V power supply

In non-self-propelled lawnmowers, all the power of the motor is used to rotate cutting mowing knives. In self-propelled lawnmowers with a wheel drive, the engine power output is distributed between the wheels and the knife system. the operator simply leads the lawnmower in the right direction, but it is not necessary to push it as a non-self-propelled.

Basic operations for mowing (may be partially absent, depending on the model):

Picking grass in a container
Ejection back
Side impact
Mulching.

How is the engine of the lawn mower

The rotary-type Oleo-Mac lawnmower is equipped with a 4-stroke Emak gasoline internal combustion engine. The engine has 1 cylinder, it has air cooling, a manual or electric starter, it works from gasoline poured into the fuel tank (it is not necessary to make a fuel mixture from gasoline and engine oil).

The Oleo-Mac Network Lawnmowers are powered by an electric motor.

What kind of oil to pour in a lawn mower

Why the Oleo-Mac does not work

Before the beginning of the spring-summer season, when you are waiting for the rapid growth of grass vegetation in your area, you suddenly find that the mower does not start or does not work the way a European high-quality mowing machine should work. We have collected answers to questions regarding the main problems that the lawn mower may encounter.

Why does a lawn mower rip grass

The rotary lawn mower is equipped with knives that, at a high speed of rotation, beat and tear grass, and this is normal for equipment in which the mowing process is more like cutting. There is a problem that after cutting, the tips of the remaining trimmed grass turn yellow quickly. It is recommended to water the lawn after mowing, this will allow the greenery to recover and not change the natural color.

But there is another problem, why grass breaks and subsequently turns brown. these are blunt knives that do not cut, but tear off the ends of the grass.

If the knives are sharpened well, and the grass breaks when mowing, then the problem may be:

In a drop in the rotation speed of the motor shaft when mowing wet, thick and tall grass.
In an incorrectly installed knife (with the wrong side. point back)
In setting an insufficient cutting height for this section (you need to increase the cutting height).

Why does the lawn mower leave grass

Uneven mowing has the same reasons as tearing grass on a mowed lawn; in addition, unequal mowing speed in different areas with acceleration or deceleration in jerks creates areas with poorly cut grass. If the cause is a dull snap, you know what to do. And the problem with uneven movement in the area needs to be fixed by developing a constant speed of walking in the area with a working lawn mower.

And also practical advice, for those who want to know how to mow the lawn correctly. look 3 meters ahead of the machine, not the wheels. So mowing is more accurate and direct.

Why is the lawn mower warming

In general, 4-stroke engines in Italian gasoline mowers heat less, make noise and vibrate, but if there is a problem with heating the mower, this may indicate the following types of malfunctions:

Bearing roll, because of which the engine is warming up and the mower stalls.
A clogged air filter, as a result of which thermal protection can trip and block the knives.

Overheating of the electric motor in the mains lawn mower may mean that the engine has been overloaded due to the following reasons:

The current passing through the windings increased above the permissible current rating.
Replacement during repair with an electric motor with a lower rated power than a previously standing city one.
Reduced or increased voltage in the network, unbalanced phase load or one of the phases missing.

This is a difficult problem from a technological point of view, which is recommended to contact an authorized service center.

Why does the mower vibrate

The occurrence of strong vibrational vibrations and jerks when the lawnmower moves across the field most likely means a damaged knife or a loosened cutting mechanism on the motor shaft. Replacing damaged items and tightening bolts will fix the situation.

Why does the mower stall

There can be many reasons why the Oleo-Mac lawnmower does not start or stall. If the cause is a broken spark plug or the need to refuel with gasoline or oil, then you can solve the problem yourself. In other cases, contact professionals.

The lawn mower does not develop speed and lose power

This situation may occur with dull knives used on wet, thick and tall grass. Another similar symptom may indicate that the problem is in the crankshaft or the engine’s seizing piston. Among the causes of engine shutdown is triggered protection when there is insufficient oil in the crankcase.

In addition to the situations listed above, a lawnmower suddenly stops suddenly and needs to check if everything is in order with the front-wheel drive belt. In gasoline models, difficulties with a stalled lawn mower may arise due to insufficient clutch cable tension, clogged air and fuel filters.

If a foreign solid object (stone, for example) enters the cutting system, a sharp decrease in engine speed occurs and it may stall. Situations after which the engine does not start at all require urgent intervention by service personnel.

The lawn mower does not start at all

Stop lever (safety clip).
Throttle position
Fuel in the tank.
If there is no oil in the crankcase or its insufficient level, the engine of the mower will not start.
Electrical analogues may not start if there is no electricity in the network, a damaged mains cable, or undervoltage.
Spark plugs are clogged or worn.
It is necessary to clean the carburetor.
Clean the air and fuel filters.

Lawn Mower Service Oleo-Mac

Oleo-Mac gasoline lawnmowers, like all gasoline powered tools, must be transported to periodic scheduled service. This is a prerequisite of the factory warranty, which allows you to keep the mower operational. In addition, your tool needs the right and good fuel, engine oil, high-quality cutting equipment. Mowing tools, whether it is a gasoline or electric Oleo-Mac lawn mower, need to be looked after, they will answer for this with trouble-free operation and accurate mowing.

What do lawn mowers run on

In the passport data there is a type of gasoline recommended by the manufacturer. It is necessary to fill in within this type of gasoline, it is not necessary to pour with a higher octane rating. The operating time of the fuel is directly proportional to the growth of the octane number. Therefore, you must adhere to the manufacturer’s recommendations so as not to create problems and premature failure of the Oleo-Mac lawn mower.

Basic rules for filling gasoline:
1. Pour fuel into the gas tank when the engine is cold.
2. Refueling away from flammable objects, open flames, do not smoke!
3. Use open area or a well-ventilated area for refueling.
4. In the refueling tank, leave a backlash for the gasoline expanding when heated.
5. Avoid getting fuel on clothing and shoes.
6. Before storing the gas mower, you must drain the gas and start the engine to work out the residues left in the carburetor.

When to change the oil in the lawn mower

Since the engine in Oleo-Mac gas mowers is 4-stroke and has an oil sump with oil to lubricate the engine, there is no need to make a fuel mixture of gasoline and oil. However, the absence of an oil filter creates the need to change the oil every 50 hours (in practice, it is enough to do this annually as soon as the oil begins to darken and loses its fluidity).

How to sharpen a lawn mower knife

Despite the advice on the Internet regarding self-cutting of knives with a file or an electric grinder, it is recommended to contact a service center. Although, experienced mowers recommend a new knife for every new season.

How to adjust the mower carburetor

The carburetor is responsible for preparing a combustible mixture of air and gasoline for supplying it to the internal combustion engine cylinders. Adjustment and cleaning of the carburetor, as well as oil change, should be carried out regularly. over, this service task is not an easy one. To adjust the carburetor for optimum performance, similar to how it is done at the factory or during pre-sale preparation, contact an authorized Oleo-Mac service center. For work, you need to use special equipment (tachometer), so adjusting the carburetor by ear or by eye is not recommended. Incorrect engine speeds will cause the engine to run at higher temperatures, which can cause overheating and engine wedges.

It is necessary to clearly know the engine speed tolerances depending on its wear, therefore, to undergo maintenance, we strongly recommend contacting authorized craftsmen.

How to wipe grass from a lawn mower

Lawn Mower Cleaning Steps:

Stop the mower, mains. disconnect from the power supply.
From the bottom of the case, from knives and wheels, the remains of wet mulch can be carefully removed with a plastic or wood spatula.
At the end of the mowing season, more thorough cleaning is needed. the knife is wiped with a rag dipped in oil. Also, grease must be applied to the levers and bearings.
Do not wash the electric lawnmower!

Benzokosa stalls

When purchasing a brushcutter, you need to be prepared for the fact that, like in all other similar tools, it can also cause breakdowns that require repair.

However, you should not immediately run to the service center and pay a lot of money to the masters who convince you of a serious malfunction in the device.

Benzokosa stalls at high speeds on gas

Perhaps the most common complaint related to gas trimmers is: “Benzokosa stalls.”

Of course, this can be caused by a rather serious malfunction. However, most often the situation is much simpler than it seems at first glance.

To cope with such a problem, first of all, try to figure out its causes on your own, because after finding out the cause, it is much easier to deal with the problem, and sometimes it will even self-destruct.

In fact, the reasons are that when the brushcutter stalls at high speeds, there are quite a few of these reasons.

Another is the presence of malfunctions in the power system.

In this case, the brushcutter will stall at idle. Out of alignment or improper carburetor adjustment can lead to problems with the power system.

Vibrations that occur during the operation of the brushcutter can lead to misalignment.

Incorrect adjustment of the brushcutter can be corrected by simply adjusting

it in accordance with the requirements specified in the instruction manual.

In addition, sometimes gasoline trimmers can stall due to the valve located in the gas tank cap simply clogging or sticking.

To find out, try using a scythe by loosening the gas tank cap.

If the device works properly in this mode, clean the valve.

over, the brushcutter may stall due to poor fuel intake in the carburetor.

Why, then, the device starts up, you ask?

The reason for this is that at first the fuel gradually runs into the carburetor and is enough to work at high power.

However, then it is developed and at high speeds the engine begins to stall.

As for the carburetor, the problem here may also be that its body is too tight.

The reason that the brushcutter stalls at high speeds on gas may also be air leaks.

We are talking about the possible presence of space through which air can pass during the heating of the engine.

In addition, be sure to check the fuel intake hose. The problem may be that it is weakly held or cracked at all.

These are the main reasons why the brushcutter can stall.
