Log Supported On One End
1. Make first cut on underside of log (see Figure
15). Use top of guide bar to make this cut. Cut
1/3 through diameter of log. This cut will keep
section from splintering when cut.
2. Make second cut directly above first cut. Cut
down to meet first cut. This cut will keep log
from pinching guide bar and chain.
Log Supported On Both Ends
1. Make first cut from above log (see Figure 16).
Cut 1/3 through diameter of log. This cut will
keep section from splintering when cut.
2. Make second cut on underside of log, directly
under first cut. Use top of guide bar to make this
cut. Cut up to meet first cut. This will keep log
from pinching guide bar and chain.
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
underside of limb. Use top of guide bar to make
this cut. Cut 1/3 through diameter of limb (see
Figure 17).
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.
