Sharpening with PowerSharp®
WARNING: PowerSharp should not
be used in the presence of exposed,
extremely flammable materials such as
gasoline and acetylene.
CAUTION: Sharpening with the
PowerSharp system produces low energy
sparks.
CAUTION: The PowerSharp integrated
sharpening system is for use only with
PowerSharp chain. Never attempt to
sharpen other chain with the integrated
sharpener. Damage to the chain and
sharpener will occur.
INTRODUCTION TO POWERSHARP
This chainsaw is equipped with the PowerSharp
integrated sharpening system, a fast and easy
way to sharpen chain on the saw. It is time to
sharpen the saw chain when cuts take longer
or the wood chips become smaller, turning the
saw to dust in extreme cases.
SHARPENING THE CHAIN
IMPORTANT: PowerSharp chain uses
unique top-sharpening cutters and
can only be sharpened with a genuine
PowerSharp sharpener.
• With the saw at full speed, lightly lift the
PowerSharp lever for 3–5 seconds (Fig. 34).
Sparks will be visible when the cutters are in
contact with the sharpening stone.
