LIMB CUT

KEEP WORK OFF GROUND

LEAVE SUPPORT LIMBS UNTIL LOG IS CUT

RIGHTWRONG

Hang-Ups

Use a portable or tractor-mounted winch to pull the tree down.

CAUTION!

Do not abandon a leaning, hung or lodged tree. Such trees are a danger to other people and must be taken down. Mark off the area if you have to leave in order to obtain assistance.

Limbing a tree

Limbing consists of removing the branches from a fallen tree.

When limbing, leave larger, lower limbs to support the log off the ground. Remove the small limbs in one cut as illustrated. Branches under tension should be cut from the botom up to avoid jamming the chain saw.

STOP WARNING!

A majority of kickback accidents occur during limbing operations. Do not engage the guide bar’s kickback zone. Take great care to avoid contact between the nose of the guide bar and the log, limbs or other objects.

Be extremely cautious of limbs under tension. They can spring back toward you and cause loss of control and injury.

1.Stand on the left side of the trunk.

2.Maintain a secure footing resting the saw on the trunk.

3.Maintain full control by holding saw close to you.

STOP WARNING!

Keep well away from chain.

4.Move only when the trunk is between you and the chain as shown.

CAUTION!

Watch out for springback from limbs under tension.

Cutting logs or wood.

Support logs on other logs, or wood on a sawhorse or equivalent. Never cut through a piece of wood that is lying on the ground. Contact with sand, stone or soil will blunt cutting edges.

If the saw jams.

Stop the motor.

Raise the log or change its position using a thick branch or pole as a lever.

STOP WARNING!

Do not try to pull the saw free. If you do, you can deform the handle or be injured by the saw chain if the saw is suddenly released.
