OPERATION
nRelease 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.
CUTTING GUIDE | Fig. 6 |
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:
nStop the engine.
nLoosen the knob on the coupler.
nDepress the button on the shaft; twist and pull the shafts to separate the pruner from the power head.
nIf the limb can be reached from the ground, lift the limb while holding the attachment. This should release the “pinch” and free the pruner.
nIf 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.
nPlan the cut carefully. Be aware of the direction in which the branch will fall.
nBranches may fall in unexpected directions. Do not stand directly under the branch being cut.
nThe 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.
�n Remove long branches in several stages.
�n Cut lower branches first to allow the top branches more room to fall.
60° MAXIMUM

nWork slowly, keeping both hands on the saw with a firm grip. Maintain secure footing and balance.
nKeep the tree between you and the chain while limbing. Cut from side of tree opposite branch you are cutting.
�n Do not cut from a ladder; this is extremely dangerous. Leave this operation for professionals.
�n 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.
�n Do not use the pruner for felling or bucking.
�n To prevent electrocution, do not operate within 50 ft. of overhead electrical lines.
�n Keep bystanders at least 50 ft. away.
