Adjustments and replacement to the bar and chain may be
carried out by the customer. All other parts should be replaced
at an authorised service centre.

the chain while the motor is running. The chain is very
sharp; always wear protective gloves when performing

REPLAcING ThE BAR ANd chAIN
See Figures 10 - 15.
For replacement Chain and Bar contact Ryobi Customer
Service.
WARNING:
To avoid possible serious injury, stop engine before
replacing the bar, chain, or performing any maintenance
operation.
Remove the bar nut and drivecase cover.
The bar contains a bar stud slot that fits over the bar
stud.
The bar also contains a chain tensioning pin hole which
fits over the chain tensioning pin.
Place the bar onto the bar stud so that the chain tension-
ing pin fits into the chain tensioning pin hole.
Fit the chain over the sprocket and into the bar groove.
The cutters on the top of the bar should face toward the
bar tip, in the direction of the chain rotation.
Replace the drive case cover and reinstall the bar nut.
Tighten the bar nut finger tight only; the bar must be free
to move for tension adjustment.
OPERATION
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 tool 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 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.
MAINTENANcE
WARNING:
When servicing, use only identical replacement parts.
Use of any other parts may create a hazard or cause
product damage.
WARNING:
Always wear safety goggles or safety glasses with side
shields during power tool operation. If operation is dusty,
also wear a dust mask.
WARNING:
Before inspecting, cleaning, or servicing the unit (except
for carburetor adjustments), shut off engine, wait for all
moving parts to stop, disconnect spark plug wire and/or
ensure that the engine cut off switch remains in the off
position. Failure to follow these instructions can result in
serious personal injury or property damage.
GENERAL MAINTENANcE

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, oil, grease, etc.
WARNING:
Do not at any time let brake fluids, petrol, petroleumbased
products, penetrating oils, etc., come in contact with
plastic parts. Chemicals can damage, weaken, or destroy
plastic, which may result in serious personal injury.
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
See Figure 9.
Lay the pruner on the ground and ensure that no objects or
obstructions are in the immediate vicinity. Make sure nothing
can come in contact with the bar and chain, including dirt on
the ground.
