CHAIN SHARPENING
Chain sharpening requires special
tools. You can purchase sharpening
tools at Sears or go to a professional
chain sharpener.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the
cut.
• Inadequate supply of oil to the bar
and chain.
Check the condition of the guide bar
before each use and each time the
chain is sharpened. A worn guide bar
will damage the chain and make cut-
ting difficult. To maintain guide bar:
1. Move ON/STOP switch to STOR
2. Remove bar and chain from saw.
3. Clean the oil holes and bar groove
after each 5 hours of operation.
4. Clean all sawdust and any other
debris from the guide bar groove
and sprocket hole after each use.

6. Burring of guide bar rails is a nor-
mal process of rail wear. Remove
these burrs with a flat file.
7. When rail top is uneven, use a flat
file to restore square edges and
sides.

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, also specified on the replace-
ment bar and chain decal located on
the chain saw.
CLEAN UNIT & LABELS
• Clean the unit and labels after each
use with a damp cloth and a mild de-
tergent.
• Wipe off unit with a clean dry cloth.
CLEAN AIR FILTER
A dirty air filter decreases the life and
performance of the engine and in-
creases fuel consumption and harmful
emissions. Always clean your air filter
after 15 tanks of fuel or 5 hours of op-
eration, whichever comes first. Clean
more frequently in dusty conditions. It
is advisable to replace your air filter
with a new one after every 50 hours of
operation, or annually, whichever
comes first. To clean filter:
1. Loosen 3 screws on cylinder cov-
er.
2. Remove cylinder cover.
3. Remove air filter.
4. Clean the air filter using hot soapy
water. Rinse with clean cool water.
Air dry completely before reinstal-
ling.
5. Reinstall air filter.
6. Reinstall air filter cover and 3
screws (15-20 in-lbs.).
