LIMBING

Limbing a fallen tree is much the same as bucking. 

Never stand on the tree that you are limbing. 

When limbing, caution is the word.  
Be careful of the tip touching other limbs.  
Always use both hands. 

Don’t cut with the saw overhead or aligned  
vertically with your body. If the saw should kick-
back, you may not have enough control to prevent 
possible injury. 

BUCKING

Bucking is the sawing of a log or fallen tree into 
smaller pieces.  
There are a few basic rules which apply to all  
bucking operations.  
Keep both hands on the handles at all times.  
Support logs if possible.  
When cutting on a slope or hillside, always stand 
uphill. 

Keep in mind that the wood is heavy and that it will 
bend and pinch the saw if improperly supported. 
The trunk will weaken at the point where you make 
the cut unless the tree is lying on perfectly flat 
ground or supported as shown.  
If you make the cut with the tree on the ground, 
don’t let the saw’s chain dig into the earth; it is 
harmful for the saw, and you stand a good chance 
of being struck by flying debris. 

To cut the trunk, use the bucking and two-cut  
sequence shown.  
The first cut should be no deeper than one-third the 
trunk diameter.

   DANGER

• Kickback is generated when the rotation of 

the chain is arrested for some reason.  
The most dangerous effect of this action 
occurs when the nose of the bar contacts 
another object, the chain is momentarily 
stopped and all the energy of the engine 
throws the bar upwards and backwards 
towards the operator. 

• The chain saw industry and government 

agencies have attempted to prescribe 
various safety devices, but the best 
protection is to avoid kickback. 

• Comply with the safety precautions as 

listed in this Manual and Safety Manual.
