WARNING: When cutting limb that

is under tension, use extreme caution.

Be alert for wood springing back. When

wood tension is released, limb could

spring back and strike operator causing

severe injury or death.

Limbing is removing branches from a fallen tree.

Make sure your footing is firm. Keep feet apart.

Divide your weight evenly on both feet. Do not

remove larger limbs under tree that support log off

ground. Remove each limb with one cut (see Figure

15). Clear cut limbs from work area often. This will

help maintain a safe work area.
Make sure you start your cut where limb will not

pinch saw during cutting. To avoid pinching, start cut

on freely hanging limbs from above limb. Start cut on

limbs under tension from under limb. If pinch occurs,

turn saw off, lift limb, and remove saw.

LIMBING A TREE

WARNING: Avoid kickback. Kickback

can result in severe injury or death. See

Kickback, pages 4 and 5, to avoid risk

of kickback.

WARNING: Be alert for falling over-

head limbs. Watch your footing while

exiting area.

3. As felling cut nears hinge, tree should begin to fall.

Note: If needed, drive wedges into felling cut to

control direction of fall. If tree settles back and

pinches chain, drive wedges into felling cut to re-

move saw. Only use wedges made of wood, plastic,

or aluminum. Never use wedge made of steel. This

could cause kickback and damage to chain.

4. When tree begins to fall, quickly

• remove saw from felling cut

• release trigger to turn saw off

• put saw down

• exit area using retreat path

4. Remove dirt, stones, loose bark, nails, staples, and

wire from tree where you will make felling cuts.

5. Stay on uphill side when felling tree. Tree could

roll or slide downhill after falling.

Felling Procedure
A) Felling Notch

A properly placed felling notch will determine direc-

tion tree will fall. Place felling notch on side of tree in

direction you want tree to fall (see Figure 14). Follow

directions below to create a felling notch.
1. Make lower notch cut as close to ground as pos-

sible. Hold saw so guide bar is horizontal. Cut

1/3 the diameter of tree trunk (see Figure 14).

Note: Always make this horizontal lower notch

cut first. If you make this cut second, tree can

pinch chain or guide bar.

2. Start upper notch cut the same distance above

first cut as first cut is deep.

Example: If lower notch cut is eight inches deep,

start upper notch cut eight inches above it. Cut

downward at 45° angle. The upper notch cut should

meet end of lower notch cut (see Figure 14).

3. Remove tree trunk wedge created by notching cuts.

B) Felling Cut

1. Make felling cut two inches higher than lower

notch cut and on opposite side of tree (see Figure

14). Keep felling cut parallel to lower notch cut.

2. Cut towards notch.

WARNING: Do not cut all the way

through tree. Leave about two inches

of tree diameter uncut directly behind

felling notch (see Figure 14). This uncut

portion acts as a hinge. The hinge helps

keep tree from twisting and falling in

wrong direction.
