Chainsaw Model CS1500
Operating the Chainsaw
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 – seconds (Fig. ).
Sparks will be visible when the cutters are in
contact with the sharpening stone.
• 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.
IMPORTANT: Do not apply too much force
when sharpening. Excessive force can
reduce the performance of the sharpening
stone.
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.
WHEN TO REPLACE 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 it
appears to have more life. See “Replacing a
Worn Saw Chain and Sharpening Stone” in this
manual.
