CLEANING AND MAINTENANCE
CARE OF GUIDE BAR
Uneven bar wear causes most guide bar prob-
lems. Incorrect sharpening of chain cutter
and depth gauge settings often cause this.
When bar wears unevenly, it widens guide
bar groove (see Figure 30). This causes chain
clatter and rivet popping. Saw will not cut
straight. Replace guide bar if this occurs.
Inspect guide bar before sharpening chain.
A worn or damaged guide bar is unsafe. A
worn or damaged guide bar will damage
chain. It will also make cutting harder.
CLEANING SAW BODY
NOTICE: Below are instructions
for servicing your chain saw. Any
servicing not mentioned below
should be done by an authorized
service center.
WARNING: Remove battery
from chain saw before servicing.
Severe injury or death could oc-
cur from body contact with mov-
ing chain.
WARNING: Cutting edges on
chain are sharp. Use protective
gloves when handling chain.
WARNING: When cleaning saw
body,
• do not submerge saw in
any liquids
• do not use products
that contain ammonia,
chlorine, or abrasives
• do not use chlorinated
cleaning solvents, carbon
tetrachloride, kerosene,
or gasoline
Keep saw body clean. Use a soft cloth damp-
ened with a mild soap and water mixture.
Wipe saw body to clean.

Normal Guide Bar Maintenance
1. Remove guide bar from chain saw.
2. Remove sawdust from guide bar
groove periodically. Use putty knife
or wire (see Figure 31).
3. Clean oil slots after each day of use.
4. Remove burrs from sides of guide
bar. Use fl at fi le to make side edges
square.
Replace guide bar when
• bar is bent or cracked
• inside groove of bar is badly worn
4. Hold fi le guide level. Make sure 30°
mark on fi le guide is parallel to cen-
ter of guide bar (see Figure 33). This
will insure that you fi le cutters at 30°
angle.
5. File from inside towards outside of
cutter until sharp. Only fi le in this one
direction (see Figure 33). Note: Two or
three strokes with fi le should sharpen
cutter.
6. After each cutter is sharpened, move
chain forward to sharpen next cutter.
File all cutters on one side of chain.
7. Move to other side of chain and repeat
process.
WARNING: Remove battery
from chain saw before servicing.
Severe injury or death could oc-
cur from body contact with mov-
ing chain.
WARNING: Cutting edges on
chain are sharp. Use protective
gloves when handling chain.
SHARPENING SAW CHAIN
Keep chain sharp. Your saw will cut faster
and more safely. A dull chain will cause
undue sprocket, guide bar, chain, and motor
wear. If you must force chain into wood and
cutting creates only sawdust with few large
chips, chain is dull.
Items Needed to Sharpen Chain
Purchase these items from your local
dealer, hardware store, or chain saw sup-
plies outlet.
• 5/32" round fi le
• Depth gauge tool
• File guide
• Vise
• Medium sized flat fi le
