Operating a chain saw should not be taken lightly. Operator carelessness, according to the Outdoor Power Equipment Institute, is the leading cause of accidents, and a good place to start regarding equipment awareness is the operator's manual. OPEI recommends regular and occasional chain saw users also should observe the following:

• Never operate a chain saw with one hand.

• Never operate a chain saw when fatigued.

• Dress accordingly, including use of safety footwear, snug-fitting clothing, protective gloves, and eye, hearing and head protection.

• Move the chain saw at least 10 feet from the fueling point before starting engine.

• Keep children, bystanders and animals away when operating the saw.

• Don't start cutting until the work area is clear, footing is secure, and there is a planned retreat path from a falling tree.

• Keep all body parts away from the saw chain when engine is running.

• Make sure saw chain is not in contact with other objects or surfaces before starting.

• Carry saw with engine off, guide bar and saw chain to the rear, and muffler away from the operator's body.
