ss7EAR SUITABLEUHEARINGBPROTECTION SUCHIAS earmuffs or earplugs to protect against objectionable or uncomfortable loud noises.

ss$O NOT LET THE TIP OF THEHBAR TOUCHPANYTHING while the engine is running.

At cutting speed the chain is moving at a high rate of speed.

Should the tip contact a limb or log while the chain is moving, the tip will be pushed upward with considerable force.

This is known as kickback. Avoid it!

In all circumstances the operation of the chain saw is a one-man job.

It is difficult at times to take care for your own safety, so don’t assume the responsibility for a helper as well.

After you have learned the basic techniques of using the saw, your best aid will be your own good common sense.

The accepted way to hold the saw is to stand to the left of the saw with your left hand on the front handlebar and your right hand on the rear 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.

Become thoroughly familiar with the controls and the responses of the saw.

Start the engine, see that it is running properly. Squeeze the trigger to open the throttle wide open and start the cut. If the chain is properly sharpened, the cutting should be relatively effortless.

It is not necessary to press down hard to make the saw cut.

Pushing the saw too hard will slow the engine and cutting will actually be more difficult.

Some material may adversely affect the housings of your chain saw.

(Example palm Tree Acid, fertilizer etc.)

To avoid housing deterioration, carefully remove all packed sawdust around clutch and guide bar area and wash with water. Coat metal parts with light oil.
