LIMBING 

Limbing is removing the branches from a felled tree. 

 WARNING! 

A majority of kickback accidents occur during limbing. 

Do not use the nose of the guide bar. Be extremely cautious and avoid contacting the log, other limbs or 

objects with the nose of the guide bar. Be extremely cautious of limbs under tension. They can spring back 

towards you and cause loss of control resulting in injury. (Fig. 2-7G) 

Stand on the left side of the trunk. Maintain a secure footing and rest the saw on the trunk. 

Hold the saw close to you so that you are in full control of it. Keep well away from the chain. 

Move only when the trunk is between you and the chain. Watch out for spring back of limbs under tension. 

LIMBING THICK BRANCHES 

When limbing thick branches, the guide bar may get pinched easily. Branches under tension often snap up, 

so cut troublesome branches in small steps. Apply the same principles as for cross cutting. 

Think ahead and be aware of the possible consequences of all your actions. 

CROSS CUTTING/BUCKING 

Before starting to cut through the log, try to imagine what is going to happen. Look out for stresses in the 

log and cut through it in such a manner that the guide bar will not get pinched. 

CROSS CUTTING LOGS, PRESSURE ON TOP  

Take a firm stance. Begin with an upper cut. 

Do not cut too deeply-about 1/3 of the log diameter is enough. 

Finish with a bottom cut. The saw cuts should meet. (Fig. 2-7H)
