CHAIN SHARPENING

WARNING: Improper chain sharp- ening 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:

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 produce a good chip.

SSaw cuts to one side or at an angle. S Saw has to be forced through the cut.

Depth Gauge

SAlign the 30˚ file holder marks paral- lel with the bar and to the center of the chain.
