Putting a chainsaw into operation, regardless of the power supply mode, is a basic notion that you must master well when you want to use such a device. Join us for the most important information you need to have to start your chainsaw without worries.
Normally, starting a chainsaw is more or less complicated, depending on the power supply mode and, possibly, its brand and model, but, in general, you will go through a few steps and the tool will start working. Here’s what you need to know in order not to have emotions when starting the device:
Starting a chainsaw for the first time can cause a certain emotion or feeling of restraint that will make you forget all the precautions to be taken. Therefore, you must remain vigilant and focused.
When starting the engine, do not hesitate to move a few meters from the cutting location, working partners or various other equipment. If the device does not start correctly, this measure taken by you will avoid possible injuries or contact with fuel barrels, for example. Make sure that the saw blade is not in contact with any other object (sheath, tree, branches, etc.).
The work area must be clear enough to have enough freedom of movement, especially when a tree falls: you must have enough space to allow you to retreat safely. Also, the chainsaw should be used in very well ventilated spaces, preferably outdoors.
Indeed, vapors related to the consumption of gasoline are harmful to humans, therefore, the air must be constantly renewed. In addition, dust, sawdust and wood chips can be inhaled, which is dangerous to health. Do not hesitate to wear a protective mask to avoid ingestion of these toxic substances.
The support handle must be clean and dry: there must be no petrol or traces of lubricating oil on the chain, with the risk of the handle slipping or losing control of the device.
There are several ways to hold the chainsaw while starting.
On the ground: The device must be placed on a flat surface and must be in a stable position, as well as the user. The chain or blade should not be in contact with anything. The left hand should hold the front handle firmly and press the saw. The right foot must be passed through the rear handle to keep the car on the ground.
Between the legs: You must tighten the back handle between the thighs or knees, and the left hand must tighten the front handle well.
Cold start of a chainsaw
First, check that the chain brake is applied correctly. Press the starter located near the end of the blade. If the saw has a compression valve, it is also possible to activate it to facilitate starting (the valve closes once the chain is started).
With your right hand, pull the starting rope until you feel resistance. From this moment, you can pull the rope several times, until it stops. From now on, you can press the launch button to “authorize” the start. When you’re done, pull the rope again: the engine will start. To release the chain, the brake must be released by pulling the handle toward you until it “clicks”. The chainsaw can be used now.
These points that I have presented to you are for information purposes only and do not replace the set of operating instructions provided with the chainsaw or available on the manufacturer’s website.
When the engine is cold, you should not run it at full speed immediately. Leave the device idling for one minute after starting to gradually warm up the engine. Also, after the work session ends, let it “spin” for a few minutes at idle to gradually reduce its temperature.
Gasoline chainsaw running-in
The manufacture of chainsaws is currently extremely precise. At the beginning of the tool life, friction is used, so that the motor elements fit and adjust to each other during the first use. Normally, it is not a necessity, especially since the chainsaws are already “rolled” in the factory. However, some manufacturers recommend a new adjustment period for new chainsaws:
For gasoline chainsaws, such as the Little Forester chainsaws (the list of the most popular models here ), during the first 3 feeds it is recommended not to run the engine at full speed, to avoid overloading it. The maximum power of the car should be reached only after 5 to 15 feeds.
Electric saw running
What I mentioned about thermal chainsaws also applies to electric chainsaws. Their manufacturing process is extremely precise and reliable, and the devices are run in the factory. As with gasoline engines, avoid using them “completely” when idling (ie without cutting wood), so as not to run the engine at overspeed.
However, electric coal motors can (and should) be run in. Indeed, the new coals that conduct electricity come into contact with the collector on a small area. Therefore, the running of the electric motor consists simply in “grinding” these coals to increase this contact surface and thus to improve the transmission of current. Using the electric chainsaw at maximum idle power can damage the coal and create electric arcs that will damage the manifold. The current will pass less and the motor will not run at full power.
The process of running an electric motor is quite technical. The engine should first be disassembled, then immersed in 90 ° alcohol and kept at low voltage for 30 minutes. Unfortunately, this method is not available to everyone. Therefore, it is recommended, when using chainsaws in the woods for the first time, to start with small diameter cuts so that you can run the engine without immediately lifting it to full power.
When the chainsaw does not start, even after four or five attempts, do not insist. First check the operating status of the starter. If not, the spark plugs must be checked. Also, make sure that the fuel tank is at least half full and that the fuel valve, if any, is open.
If the starter fulfills its function and if the petrol reaches the carburetor, it is necessary to check the ignition. If the chainsaw stops when you accelerate , there may be a carburetor failure.
