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.

CARE OF GUIDE BAR

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

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, 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.
