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:
SReduction 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.
SSaw 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
SFlat file
SDepth 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.

SFile on the forward stroke only. Use 2 or 3 strokes per cutting edge.
SKeep all cutters the same length when filing.
SFile enough to remove any dam- age to cutting edges (side plate and top plate of cutter).
