Before performing any maintenance, make sure
the tool is unplugged from the power supply to
avoid accidental starting and possible serious
personal injury.
For smooth and fast cutting, the chain needs to
be maintained properly. The following conditions
indicate that the chain requires sharpening:
 Wood chips are small and powdery
 Chain must be forced through the wood during
cutting
 Chain cuts to one side
During maintenance of the chain, consider the
following:

 Improper filing angle of the side plate can in-
crease the risk of a severe kickback.
 Depth gauge (or raker clearance) setting de-
termines the height the cutter enters the wood
and the size of the wood chip that is removed.
