When the chainsaw starts and stops, it is caused by the carburetor or other parts. Causes of the malfunction:

  • Fuel does not flow well to the engine. It is due to a clogged breather.
  • Not enough fuel in the tank. Tilting the tool sideways, fuel residue runs off in one place. This causes the saw to stop working.
  • The fuel is of poor quality.
  • The spark plug insulator overheats when there is poor contact between the wire cap and the spark plugs. The contact between them becomes worse with sooting or mechanical shifting.
  • Spark plugs are faulty.
  • Fuel does not flow smoothly to carburetor through fuel filter or pump. As soon as the tool starts to rev up, it immediately stops.
  • If the air filter is dirty, the engine cannot withstand the high loads and stops.
  • Insufficient or no lubrication in the chain.

Depending on the chainsaw brand, parts of the lubrication system may vary slightly structurally, but their total number and connection scheme remains the same.

The main components of the lubrication system, are:

  • oil tank usually located in the engine crankcase.
  • Filter element, installed in the tank.
  • Lube line is a small diameter hose made of oil-resistant rubber.
  • The heart of the system. the oil pump.
  • The worm gear that transmits power from the engine to the pump.
  • The chain saw bar, it too can be considered an element of the lubrication system, as it has special holes for feeding oil, by the way and the chain itself is involved in the transportation of oil and therefore also has some elements designed just to provide lubrication.

How to start the chainsaw

  • Before starting the engine for the first time, all the parts of the Partner 351 chain saw should be securely tightened and the integrity of the housing checked.
  • Check chain tension before starting. The chain is tensioned or loosened as needed with the adjustment screw.
  • Check the amount of oil before each start.

How a chainsaw works

It should be noted that all chainsaws. Traditional devices, powered by an internal combustion engine.

Electric chainsaw ignition chain.

chainsaws are built with single-cylinder engines that use high-octane gasoline. The machine has no gearbox. It is a single-stage box that drives the chain. Simple design. The reliability and ruggedness of the tool, even in adverse conditions of use.

In addition to these units, the design of the chainsaw includes a cleaning system of air, which is fed to the engine to make a combustible consistency, the bar with the saw chain installed on it, the starter, which starts the power plant chainsaw, the chain tensioning mechanism, the ignition system and the system of depressing the exhaust. In addition, the chainsaw design provides the so-called emergency brake, which allows in an emergency situation to shut off the chainsaw power unit from the drive sprocket to prevent injury to the person operating the device.

Ignition system and chain saw starter

Chainsaws are now equipped with electric ignition units that don’t require adjustment or cleaning. The ignition system includes a flywheel with magnets, a module with an electrical system, a spark plug and a high-voltage wire.

The starter built into the device is used to start the saw motor by turning the crankshaft. The starter mechanism contains the following elements:

With a sharp pull of the cable, the starter ratchet engages with the teeth of the crankshaft, which causes it to rotate. A return spring is provided to reset the cable to its original position. To start the power plant you need to apply a certain force, because the engine starts only at a certain speed of rotation of the crankshaft.

Basic tuning

  • Tighten the screw T clockwise as far as it will go and then turn it 4.5 turns in the opposite direction.
  • Carefully tighten the H and L screws all the way down, then back them out two turns.
  • If the engine does not stall at idle, the chain does not move, the engine rapidly accelerates and runs smoothly, it’s pretty basic adjustment. In the unpleasant case, a clear adjustment is required. The chainsaw should be started and warmed up for 5-10 minutes.

How to start the chainsaw

The efficiency of any tool directly depends on compliance with the rules of its use. First and foremost, it’s about startup. This should be done in this sequence:

  • Start the chain brake, for which it must be pressed in the forward direction.
  • Remove the guide bar cover, if present.
  • Include a decompression valve to make starting easier.
  • Press in the fuel intake. This is to reduce the number of pulls.
  • Move the combination lever all the way down to the no-load start position by first locking the gas lever.
  • Position the tool on a flat surface, take the chainsaw with both hands in such a way that its cutting part is at a distance from this surface. Hold the handle with your left hand and the starter rope with your right hand. The tool must be secured with your foot, for which you can simply step on the back handle.
  • Now pull the starter rope taut and then pull it several times. Working in upward direction away from the housing.
  • The engine will stop after a short restart. So after that you need to move the combination lever up by one click and then restart.
  • If the engine is running, the throttle lever must be pressed and the combination lever must be set to idle.
  • The chain brake should now be removed and you can start using the tool.

Despite the simplicity of the process, some situations can arise where the chainsaw will not start. The reasons are not always related to the breakage of the tool. Maybe just not enough force was applied. If still after several attempts to start was unsuccessful, it is worth a thorough inspection of the unit.


Reviews that can be found on the Internet:

I do part-time work in the forestry. The workers there use, of course, professional saws, and I was given a chainsaw Poulan. I liked the machine, it is easy to start, easy to use. The vibrations are minimal and it works for a long time without cooling, even when it’s hot outside. (Dmitry).

I have used a Poulan saw for almost 5 years, my experience has been positive and I am satisfied with the reliability of the plastic parts. (Fedor).
