• Replace the sharpening Stone when a new
Power Sharp + chain is installed, The sharpen-
ing stone will wear to the shape of the worn chain
and will cause excessivewear to a new chain if not
replaced. Replacement Power Sharp_+ Chain,
Stock No. 71-3618, comes suppliedwith a Shar-
pening Stone Replacement. Refer to replacement
instructionsinthis section.
tCAUTIONilAIways wear gloves when handling
the chain. The chain is sharp and can cut
you easily, even when it is not moving.
e 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 cuts to one side.
--saw has to be forced through the cut.
• Remove the sharpening stone ifa standard orcon-
ventional, chisel-type chain is substituted for the
PowerSha_ ® Chain. See inst.j._Jonsfor,_moving
