Limbing And Pruning - Ryobi RY40050 Manuel D'utilisation

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 motor can result.
 Release the trigger as soon as the cut is com-
pleted.
Failure to follow proper cutting procedures will
result in the bar and chain binding and becom-
ing pinched or trapped in the limb. If this should
happen:
 Stop the motor and remove the battery pack.
 If the limb can be reached from the ground,
lift the limb while holding the saw. This should
release the "pinch" and free the saw.
 If the saw is still trapped, call a professional for
assistance.

LIMBING AND PRUNING

See Figures 10 - 11.
This unit is designed for trimming small branches
and limbs up to 6 in. in diameter. For best results,
observe the following 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 posi-
tion the unit at an angle of 60° or less, depend-
ing on the specific situation, as shown. As the
angle of the pole saw 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 branch-
es 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 dan-
gerous. Leave this operation for professionals.
OPERATION
 Do not 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 pole saw for felling or bucking.
 To prevent electrocution, do not operate within
50 ft. of overhead electrical lines.
 Keep bystanders at least 50 ft. away.
