CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A dull

chain makes a sawdust powder and cuts

slowly . See CHAIN SHARPENING.

nance:

S Saw cuts to one side or at an angle.

S Saw has to be forced through the cut.

S Inadequate supply of oil to bar/chain.

Check the condition of guide bar each time

chain is sharpened. A worn guide bar will

damage the chain and make cutting difficult.

After each use, ensure ON/STOP switch is

in the STOP position, then clean all sawdust

from the guide bar and sprocket hole.
