OPERATING CHAIN SAW
Continued
Trimming a tree is the process of cutting limbs from
a living tree. Make sure your footing is firm. Keep
feet apart. Divide your weight evenly on both feet.
Follow directions below to trim a tree.
1. Make first cut six inches from tree trunk on un-
derside of limb. Use top of guide bar to make
this cut. Cut 1/3 through diameter of limb (see
Figure 16).
2. Move two to four inches farther out on limb.
Make second cut from above limb. Continue cut
until you cut limb off.
3. Make third cut as close to tree trunk as possible
on underside of limb stub. Use top of guide bar to
make this cut. Cut 1/3 through diameter of stub.
4. Make fourth cut directly above third cut. Cut down
to meet third cut. This will remove limb stub.
CLEANING AND
MAINTENANCE
NOTICE: Below are instructions for ser-
vicing your chain saw. Any servicing not
mentioned below should be done by an
authorized service center.
CLEANING SAW BODY
WARNING: Unplug chain saw from
power source before servicing. Severe
injury or death could occur from electrical
shock or body contact with moving 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 am-
monia, chlorine, or abrasives
• do not use chlorinated cleaning sol-
vents, carbon tetrachloride, kerosene,
or gasoline
Keep saw body clean. Use a soft cloth dampened with
a mild soap and water mixture. Wipe saw body to clean.
CARE OF GUIDE BAR
Uneven bar wear causes most guide bar problems.
Incorrect sharpening of chain cutter and depth gauge
settings often cause this. When bar wears unevenly,
it widens guide bar groove (see Figure 17). 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.
Normal Guide Bar Maintenance
1. Remove guide bar from chain saw.
2. Remove sawdust from guide bar groove periodi-
cally. Use putty knife or wire (see Figure 18).
3. Clean oil slots after each day of use.
4. Remove burrs from sides of guide bar. Use flat
file to make side edges square.
Replace guide bar when
• bar is bent or cracked
• inside groove of bar is badly worn
Note: When replacing guide bar, see Replacement
Parts and Accessories, page 21, for proper bar.
SHARPENING SAW CHAIN
WARNING: Unplug chain saw from
power source before servicing. Severe
injury or death could occur from electrical
shock or body contact with moving chain.
WARNING: Cutting edges on chain
are sharp. Use protective gloves when
handling 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, hard-
ware store, or chain saw supplies outlet.
• 5/32" round file
• Depth gauge tool
• File guide
• Vise
• Medium sized flat file
Sharpening Cutters
Use file guide for 30° filing.
1. Adjust chain for proper tension (see Saw Chain
Tension Adjustment, pages 16 and 17).
2. Clamp guide bar in vise to hold saw steady. Note:
Do not clamp chain.
3. Press 5/32" round file (attached to file guide) into
groove between top plate and depth gauge on
chain. File guide should rest on both top plate
and depth gauge (see Figure 19). Note: File at
midpoint of guide bar.
