Operation - Ryobi RY52004 Operator's Manual

n 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.
CUTTING GUIDE
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:
n Stop the engine.
n Loosen the knob on the coupler.
n Depress the button on the shaft; twist and pull the shafts
to separate the pruner from the power head.
n 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.
n 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.
n Plan the cut carefully. Be aware of the direction in which
the branch will fall.
n Branches may fall in unexpected directions. Do not stand
directly under the branch being cut.
n 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.
n Remove long branches in several stages.
n Cut lower branches first to allow the top branches more
room to fall.

OPERATION

n Work slowly, keeping both hands on the saw with a firm
grip. Maintain secure footing and balance.
n Keep 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.
