CUTTING GUIDE

Fig. 6

NOTE: 

For second and final cuts (from top of limb or branch), 

hold front cutting guide against the limb being cut. This will 
help steady the limb and make it easier to cut. Allow chain to 
cut for you; exert only light downward pressure. If you force 
the cut, damage to the bar, chain, or engine can result.

  Release the trigger as soon as the cut is completed, allow-

ing the engine to idle. If you run the pruner at full throttle 
without a cutting load, unnecessary wear or damage can 
occur to the chain, bar, and engine.

Failure to follow proper cutting procedures will result in the 
bar and chain binding and becoming pinched or trapped in 
the limb. If this should happen: 

  Stop the engine. 

  Loosen the knob on the coupler. 

  Depress the button on the shaft; twist and pull the shafts 

to separate the pruner from the power head. 

  If the limb can be reached from the ground, lift the limb 

while  holding  the  attachment.  This  should  release  the 
“pinch” and free the pruner. 

  If the pruner is still trapped, call a professional for as-

sistance.

LIMBING AND PRUNING 

See Figures 8 - 9.

This unit is designed for trimming small branches and limbs 
up to 6 in. in diameter. For best results, observe the follow-
ing precautions.

  Plan the cut carefully. Be aware of the direction in which 

the branch will fall.

  Branches may fall in unexpected directions. Do not stand 

directly under the branch being cut.

  The most typical cutting application is to position the unit 

at an angle of 60° or less, depending on the specific situ-
ation, as shown below. As the angle of the pruner shaft 
to ground increases, the difficulty of making the first cut 
(from the underside of limb) increases. 

  Remove long branches in several stages.

  Cut lower branches first to allow the top branches more 

room to fall.

  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.  

Cut from side of tree opposite branch you are cutting.

  Do not cut from a ladder; this is extremely dangerous.  

Leave this operation for professionals.

  Do 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. Following proper cutting procedures will prevent 
stripping the bark from the main member. 

  Do not use the pruner for felling or bucking.

  To prevent electrocution, do not operate within 50 ft. of 

overhead electrical lines.

  Keep bystanders at least 50 ft. away.
