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 c ut y ou even when it is
not moving.
Conditi ons which indicat e the need for
chain shar pen ing:
S Reduction in s ize 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 ch ip. Note
that dead or rotted wood will not pro-
duce a good chip.
S Saw cuts to one side or at an ang le.
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
