2. Keep a good firm grip on the saw with both hands, the right hand on the 
rear handle, and the left hand on the front handle, when the engine is 
running. Use a firm grip with thumbs and fingers encircling the chain 
saw handles. A firm grip will help you reduce kickback and maintain 
control of the saw. Don’t let go.
3. Make sure that the area in which 
you are cutting is free from 
obstructions. Do not let the nose 
of the guide bar contact a log, 
branch, or any other obstruction 
which could be hit while you are 
operating the saw.
4. Cut at high engine speeds.
5. Do not overreach or cut above 
shoulder height.
6. Follow manufacturer’s sharpening and maintenance instructions for the 
saw chain.
7. Only use replacement bars and chains specified by the manufacturer or 
the equivalent.
Correct Use Of Chain Brake
Chain Brake Operation
• Set the lever in the unlocked position before starting to cut.
• If the brake is tripped by kickback 
reaction, the chain will stop 
immediately. Release the throttle 
to avoid possible damage to the 
engine or clutch.
• Do not attempt to operate the 
engine with the brake locked.
Testing The Brake
• Start the engine on a solid level 
surface and run at a fast idle until 
warm.
• Hold the saw firmly by the 
handles and accelerate the 
engine to a fast idle.
