GENERAL SAFETY RULES

ALL CHAIN SAW SERVICE, other than the items listed in the instruction manual and all maintenance, should be performed by competent chain saw service personnel. (For example, if improper tools are used to remove the flywheel or if an improper tool is used to hold the flywheel in order to remove the clutch, structural damage to the flywheel could occur and subsequently could cause the flywheel to burst.)

KEEP SAFE-T-TIP ANTI-KICKBACK NOSE GUARD properly mounted on the guide bar to prevent rotational kickback.

FOLLOW THE SHARPENING and maintenance instructions for the saw chain.

USE ONLY THE REPLACEMENT GUIDE BARS and low kickback chains specified for your saw.

DO NOT adapt your powerhead to a bow guide or use it to power any attachments or devices not listed for your saw.

SAVE THESE INSTRUCTIONS. Refer to them fre- quently and use to instruct other users. If you loan someone this tool, loan them these instructions also.

SPECIFIC SAFETY RULES

WARNING:

The warnings, labels, and instructions found in this section of the operator's manual are for your safety. Failure to follow all instructions may result in serious personal injury.

GENERAL PRECAUTIONS

DO NOT CUT VINES and/or small underbrush (less than 3 in./76 mm in diameter).

MUFFLER SURFACES ARE VERY HOT during and after operation of the chain saw; keep all body parts away from the muffler. Serious burns may occur if contact is made with the muffler.

Always hold the chain saw with both hands when the engine is running. Use a firm grip with thumbs and fingers encircling the chain saw handles.

Never let anyone use your chain saw who has not received adequate instructions in its proper use. This applies to rentals as well as privately owned saws.

Before you start the engine, make sure the saw chain is not contacting any object.

Operate the chain saw only in well ventilated areas.

SAFETY APPAREL

Wear snug fitting clothing. Always wear heavy, long pants, boots, and gloves. Do not wear jewelry, short pants, sandals, or go barefoot. Do not wear loose fitting clothing, which could be drawn into the engine or catch the chain or underbrush. Wear overalls, jeans, or chaps made of cut resistant material or ones that contain cut resistant inserts. Secure hair so that it is above shoul- der level.

Wear non-slip safety footwear and heavy-duty gloves to improve your grip and to protect your hands.

Wear eye protection which is marked to comply with ANSI Z87.1, as well as, hearing and head protection when operating this equipment.

REFUELING (DO NOT SMOKE!)

To reduce the risk of fire and burn injury, handle fuel with care. It is highly flammable.

Mix and store fuel in a container approved for gasoline.

Mix fuel outdoors where there are no sparks or flames.

Select bare ground, stop the engine, and allow it to cool before refueling.

Loosen the fuel cap slowly to release pressure and to keep fuel from escaping around the cap.

Tighten the fuel cap securely after refueling.

Wipe spilled fuel from the unit. Move 30 feet (9 m) away from refueling site before starting engine.

Never attempt to burn off spilled fuel under any circum- stances.

CUTTING/WORK AREA

Do not operate a chain saw in a tree.

Do not cut from a ladder, this is extremely dangerous.

Keep bystanders and animals out of the work area. Do not allow other persons to be nearby during starting or cutting with the chain saw.

Note: The size of the work area depends on the job being performed as well as the size tree or workpiece involved. For example, felling a tree requires a larger work area than making other cuts (i.e., bucking cuts, etc.).
