when handling chain The chain is sharp and
can cut you even when it is not mowng.
Cond_ons which indicate the need for chain
sharpening:
• Reduction in size of wood chips The size
of the wood chip wiil 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.
• Saw cuts to one side or at an angle
• Saw has to be forced through the cut.
