USING THE POWER SHARP SYSTEM
[MODEL .3536901
12
Model .353690 is equipped with a Power Sharp
System that will perform approximately 80% of
the sharpening necessary for the saw chain. The
Power Sharp System utilizes a built-in grinding
stone to sharpen the cutter top plates,and set
depth gauges. As the built-in sharpener is used,
the cutter side plates gradually will be altered,
About every 3rd to 5th time the Power Sharp
System is used, hand filing is required to correct
the c_btter side plates.
• Sharpen the saw chain when:
--wood chips become small and powdery.
Wood chips made by the chain should be
about the size of the teeth of the chain.
--saw_e_uts to one side.
--saw has to be forced through the cut.
