Maintenance; Operation - Ryobi RY52604 Operator's Manual

 Do not cut from a ladder; this is extremely dangerous.
Leave this operation for professionals.
 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 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.
POSITION FOR STARTING

obstructions are in the immediate vicinity. Make sure nothing
can come in contact with the bar and chain. Ensure that the
bar and chain is not touching the ground.

MAINTENANCE

GENERAL MAINTENANCE
Avoid using solvents when cleaning plastic parts. Most
plastics are susceptible to damage from various types of
commercial solvents and may be damaged by their use. Use
clean cloths to remove dirt, dust, lubricant, grease, etc.
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating lubricant, etc., come in con-
tact with plastic parts. Chemicals can damage, weaken, or
destroy plastic, which may result in serious personal
injury.
All pruner service, other than the items listed in the instruc-
tion manual maintenance instructions, should be performed
by competent pruner service personnel. (For example, if
improper tool is used to hold the flywheel in order to remove
the clutch, structural damage to the flywheel could occur
and subsequently could cause the flywheel to burst).
