CHAIN REPLACEMENT
• Inadequate supply of oil to the bar
and chain.
Check the condition of the guide bar
each time the chain is sharpened. A
worn guide bar will damage the chain
and make cutting difficult. To maintain
guide bar:
• Disconnect the chain saw from the
power source. See instructions under
"Chain Replacement".
• Remove bar and chain from saw.
• Clean all sawdust and any other
debris from the guide bar groove and
sprocket hole after each use.
Remove Sawdust From Guide
Bar Groov_
Sprocket Hole
• Add lubricant to sprocket hole after
each use.
• Burring of guide bar rails is a normal
process of rail wear. Remove these
burrs with a flat file.
• When rail top is uneven, use a flat file
to restore square edges and sides.
File Edges and
sides Square
Worn Groove Correct Groove
Replace the guide bar when the groove
is worn, the guide bar is bent or
cracked, or when excess heating or
burring of the rails occurs. If replace-
ment is necessary, use only the guide
bar specified for your saw in the repair
parts list or on the decal located on the
chain saw.
CLEAN UNIT & LABELS
• Clean the unit and labels using a
damp cloth with a mild detergent.
• Wipe off the unit and labels with a
clean dry cloth.
WARNING: Avoid accidental starting.
Always unplug the saw from the power
source before installing a bar and/or
chain.
CAUTIO N: Wear protective gloves
when handling chain. The chain is
sharp and can cut you even when it is
not moving.
It is normal for a new chain to stretch
during the first 30 minutes of operation.
You should recheck your chain tension
frequently and adjust the chain tension
as required. See "Check Chain Ten-
sion" in the Maintenance section.
