LIMBING
Limbing is removing the branches from a feller
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)
THICK LOG, LARGER THAN GUIDE BAR
LENGTH
Begin by cutting on the opposite side of the 
log. Pull the saw towards you followed by
previous procedure. (Fig. 2-7J)
If the log is lying on the ground make a boring
cut to avoid cutting into the ground. Finish with 
a bottom cut. (Fig. 2-7K)
WARNING! KICKBACK DANGER!!
Do not attempt a boring cut if you are not 
properly trained. A boring cut involves the use 
of the nose of the guide bar and can result in 
kickback.
CROSS CUTTING LOGS, PRESSURE ON 
BOTTOM
Take a firm stance. Begin with a bottom cut.
The depth of the cut should be about 1/3 of 
the log diameter.
Finish with an upper cut. The saw cuts should 
meet. (Fig. 2-7L)
THICK LOG, LARGER THAN GUIDE BAR
LENGTH
Begin by cutting on the opposite side of the 
log. Pull the saw towards you, followed by
previous procedure.
Make a boring cut if the log is close to the 
ground.
Finish with a top cut. (Fig. 2-7M)
WARNING! KICKBACK DANGER!!
Do not attempt a boring cut if you are not 
properly trained. A boring cut involves the 
use of the nose of the guide bar and can 
result in kickback. (Fig. 2-7N)
IF THE SAW GETS STUCK 
Stop the engine.
Raise the log or change its position, using a 
thick branch or pole as a lever.
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.
