Cleaning the Saw Body
Sharpening the chain (continued)
Make a test cut to determine if the chain has been sufficiently sharpened. If not,
repeat the sharpening procedure until the chain is sufficiently sharp.
CAUTION: SHARPENING WITH THE POWERSHARP ® SYSTEM
PRODUCES LOW ENERGY SPARKS.
WARNING: POWERSHARP SHOULD NOT BE USED IN THE PRESENCE OF
EXPOSED, EXTREMELY FLAMMABLE MATERIALS, SUCH AS GASOLINE
AND ACETYLENE.
IMPORTANT: IT IS NORMAL TO SEE A SMALL AMOUNT OF SPARKS AND
SMOKE DURING SHARPENING, AS THE CUTTERS CONTACT THE STONE
AND FRICTION HEATS THE CHAIN.
REPLACING THE SHARPENING STONE
The sharpening stone is designed to wear at the same rate as the chain.
Always replace the stone when replacing the chain, even if appears to have
more life.
CAUTION: REPLACE POWERSHARP ® SAW CHAIN AND THE
SHARPENING STONE AT THE SAME TIME. FAILURE TO DO SO COULD
RESULT IN DECREASED PERFORMANCE OR DAMAGE TO THE CHAIN
AND/OR SHARPENING STONE.
IMPORTANT: THE POWERSHARP ® INTEGRATED SHARPENING SYSTEM
IS FOR USE ONLY WITH POWERSHARP CHAINS.
With the chainsaw off and cool, and the power line removed from the power
supply, remove the side cover by removing the side cover knob. Install the new
sharpening stone as follows:
Remove the two screws holding the sharpening stone. Remove the stone (See
Fig. W).
Make sure the PowerSharp ® lever and surrounding area are free of debris.
Place the new stone in position. Replace the screws and tighten snugly.
Reinstall the side cover and tighten the side cover knob.
