UNdERbUCKING
See Figure 1.
Begin on the under side of the log with the top of the saw 
against the log; exert light pressure upward. During under-
bucking, the saw will tend to push back at you. Be prepared for 
this reaction and hold the saw firmly to maintain control.
LIMbING ANd PRUNING
See Figures  - .
Work slowly, keeping both hands on the saw with a firm 
grip. Maintain secure footing and balance.
 Keep the tree between you and the chain while limbing.
Do not cut from a ladder. This is extremely dangerous. 
Leave this operation for professionals.
 Do not cut above chest height. A saw held higher than 
chest height is difficult to control against kickback.
WARNING:
Never climb into a tree to limb or prune. Do not stand on 
ladders, platforms, a log, or in any position which can 
cause you to lose your balance or control of the saw.
 When pruning trees it is important not to make the flush 
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.
  •  Underbuck the branch 1/3 through for your first cut.
  •  Overbuck the branch to drop it.
  •  Finish  by  cutting  smoothly  and  neatly  against  the 
main member so the bark will grow back to seal the 
wound.
WARNING:
If the limbs to be pruned are above chest height, hire a 
professional to perform the pruning.
CUTTING SPRINGPOLES
See Figure .
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.
