CHAIN SHARPENING

WARNING:
Improper chain sharpen-
ing techniques and/or depth gauge mainte-
nance will increase the chance of kickback
which can result in serious injury.
WARNING:
Wear protective gloves
when handling chain. The chain is sharp and
can cut you even when it is not moving.
Conditions which indicate the need for chain
sharpening:
S Reduction in size of wood chips. The size
of the wood chip will decrease as the chain
gets duller until it becomes more like a
powder than a chip. Note that dead or
rotted wood will not produce a good chip.
S Saw cuts to one side or at an angle.
S Saw has to be forced through the cut.
Tools required:
S 5/32 inch (4 mm) diameter round file and
file holder
S Flat file
S Depth gauge tool
TO SHARPEN CHAIN:
1. Move ON/STOP switch to the STOP
position.
2. Check chain for proper tension. Adjust
chain tension if necessary. See CHAIN

3. Sharpen cutters.
S To sharpen the cutters, position the
3
/ inch
file holder level (90˚) so that it rests
4
on the top edges of the cutter and
depth gauge.
NOTE:
