CHAIN MAINTENANCE
See Figures 35 - 36.
WARNING:
Before performing any maintenance, make sure
the tool is unplugged from the power supply to
avoid accidental starting and possible serious
personal injury.
Use only a low-kickback chain on this saw. This
fast- cutting chain provides kickback reduction
when properly maintained.
For smooth and fast cutting, maintain the chain
properly. The chain requires sharpening when the
wood chips are small and powdery, the chain must
be forced through the wood during cutting, or the
chain cuts to one side. During maintenance of the
chain, consider the following:
 Improper filing angle of the side plate can
increase the risk of severe kickback.
 Raker (depth gauge) clearance.
• Too low increases the potential for kickback.
• Not low enough decreases cutting ability.
 If the cutter teeth hit hard objects such as nails
and stones, or are abraded by mud or sand on
the wood, have an authorized service center
sharpen the chain.
MAINTENANCE
NOTE: Inspect the drive sprocket for wear
or damage when replacing the chain. If signs
of wear or damage are present in the areas
indicated, have the drive sprocket replaced by
an authorized service center.
NOTE: If you do not fully understand the correct
procedure for sharpening the chain after reading
the instructions that follow, have the saw chain
sharpened by an authorized service center or
replace with a recommended low-kickback chain.
