Abstract: Chainsaw is short for gasoline saw chain or gasoline-powered saws, which are power saws used for logging and timber building. A Chainsaw engine is a two-stroke engine, the use of fuel for the oil and gasoline mixture. Fuel configuration can not be randomly allocated, must be strictly by the machine comes with the oil distribution pot oil distribution. Mixed oil should be used now, can not use has been configured for a long time mixed oil. The following article is specific for you to introduce the common knowledge of the chainsaw, I hope you can help.

Chainsaws are easy to carry, operation recommendations, that is, in terms of maintenance is more complex, need to pay attention to many aspects:

1. Before working on the chainsaw, you need to let it run at low speed for a few minutes to see the chainsaw lubrication saw chain machine oil called a line of oil before you can start working. When working, the throttle can be set to use at high speed. Did not work through 1 tank of oil, need to rest for a period of time, roughly 10 minutes. After the work is completed, you need to clean up the chain saw's heat sink to ensure that the machine's normal heat dissipation.

2. Chainsaw air filter every 25 hours to dust, if encounter special circumstances, you can deploy it. The foam filter can be cleaned with washing liquid or gasoline, and then cleaned again with water, squeeze to dry, and then soaked in oil, squeeze the excess oil can be installed.

3. When using the new chainsaw, you need to pay attention to the tightness of the saw chain to be able to push the saw chain rotation, hand-held saw chain, guide teeth and guide plate parallel shall prevail, use a few minutes, pay attention to the observation again, and so on a few times.

In the use of chainsaws, to ensure that there is no biological existence around 20 meters, check the grass there are no hard objects, rocks, etc., to ensure safety. For the chainsaw needs to be set aside when not in use, you need to clean the body, drain the fuel mixture, burn out the fuel in the carburetor; remove the spark plug, add 1-2ml of 2 stroke oil to the cylinder, pull the starter 2-3 times, and install the spark plug.

What is the reason why the chainsaw can not start?

First: check the oil and electric circuit, see if the oil filter is not clogged, the carburetor is pumping oil normally, whether the spark plug is electric, remove the spark plug and put the top on top of the metal, pulling the machine is able to see whether the spark plug is electric.

Second: remove the air filter, by the way, check whether the air filter is clean.

Third: remove the carburetor, and then drop a few drops of oil into the cylinder, and start the machine a few times. If it doesn't start, you'll have to wash the carburetor or replace it, and finally check the cylinder. Teach you a way to maintain the machine, if you do not use the machine for a long time in the future, you have to put the oil tank to the oil out. Start the machine to burn through the carburetor and cylinder oil. In order to avoid residual oil clogging carburetor, usually more cleaning air filter, lubricant must be used to lubricate the effect of some good.

What is the reason for the chain saw to stall?

There are generally two situations:

1 Suddenly add flameout: the transition of the carburetor is not good, the L screw of the carburetor needs to be readjusted.

2 idle stall: air leakage or carburetor adjustment mismatch.
