OPERATION

LIMBING

See Figure 20.

Limbing is removing branches from a fallen tree.

Work slowly, keeping both hands on the chain saw with a firm grip. Always make sure your footing is secure and your weight is distributed evenly on both feet.

Leave the larger support limbs under the tree to keep the tree off the ground while cutting.

Limbs should be cut one at a time. Remove the cut limbs from the work area often to help keep the work area clean and safe.

Branches under tension should be cut from the bottom up to avoid binding the chain saw.

Keep the tree between you and the chain saw while limbing. Cut from the side of the tree opposite the branch you are cutting.

SPRINGPOLES

See Figure 22.

A springpole is any log, branch, rooted stump, or sapling which is bent under tension by other wood so that it springs back if the wood holding it is cut or removed. On a fallen tree, a rooted stump has a high potential of springing back to the upright position during the bucking cut to separate the log from the stump. Watch out for springpoles, they are dangerous.

WARNING:

Springpoles are dangerous and could strike the operator, causing the operator to lose control of the chain saw. This could result in severe or fatal injury to the operator.

PRUNING

See Figure 21.

Pruning is trimming limbs from a live tree.

Work slowly, keeping both hands on the chain saw with a firm grip. Always make sure your footing is secure and your weight is distributed evenly on both feet.

When pruning trees it is important not to make

 

 

 

 

 

 

 

 

 

the finishing cut next to the main limb or trunk

 

 

 

 

 

 

 

 

 

 

 

 

until you have cut off the limb further out to

 

 

 

 

 

 

reduce the weight. This prevents stripping the

 

 

 

 

 

 

bark from the main member.
