SERVICE AND ADJUSTMENTS
CHAIN SHARPENING
WARNING: Improper chain sharp-
ening techniques and/or depth gauge
maintenance will increase the chance of
kickback which can result in serious in-
jury.
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 pro-
duce 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. Ad-
just chain tension if necessary. See
CHECK CHAIN TENSION section.
3. Sharpen cutters.
S To sharpen the cutters, position
the file holder level (90 ˚) so that it
rests on the top edges of the cut-
ter and depth gauge.
NOTE: The chain has both left
and right hand cutters.
