SERVICE AND ADJUSTMENTS
CHAIN SHARPENING
WARNING: Impr oper chain sharp-
ening techniques and/or depth gauge
maintenance will increase the chance of
kickback which can resul t in ser i o us injury.
WARNING: Wear protective gloves
when handling chain. The chain is sharp
and can cut you even when it is not mov-
ing.
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
TO SHARPEN CHAIN:
1. Move

S To s harpen the cutters, position
the file holder level (90˚) so that it

ter and depth gauge.
