19Cutting instructionGeneralIn all circumstances the operation of the chain saw is a one-man job.It is difficult at times to take care of your own safety, so don't assume the responsibility for ahelper as well.After you have learned the basic techniques of using the saw, your best aid will be your owngood common sense.The accepted way to hold the saw is to stand to the left of the saw with your left hand on thefront handle so you can operate the throttle trigger with your right index finger.Before attempting to fell a tree, cut some small logs or limbs.Be thoroughly familiar with the controls and the responses of the saw.Start the engine, see that is running properly.Squeeze the trigger to open the throttle wide open, then start the cut.It is not necessary to press down hard to make the saw cut.If the chain is properly sharpened, the cutting should be relatively effortless.Pushing the saw too hard will slow the engine and cutting will actually be more difficult.Some material may adversely affect the housing of your chain saw.(Example: palm tree acid, fertilizer etc.)To avoid housing deterioration carefully remove all packed saw dust around clutch and guidebar area and wash with water.DANGERDo not let the nose or tip of the guide bar touch anything while engine is running toavoid kickback.
