MAINTENANCE
Remove the brush cap with a flat blade screwdriver.
Brush assembly is spring loaded and will pop out when
you remove the brush cap.
Remove the brush assembly (brush and spring).
Check for wear. If worn, always replace in pairs. DO
NOT replace one side without replacing the other.
Reassemble using new brush assemblies.
Make sure curvature of brush matches curvature of
motor and that the brush moves freely in the brush tube.
Make sure the brush cap is oriented correctly (straight)
and replace.
Tighten the brush cap securely. DO NOT over tighten.
PROPER CARE OF CUTTERS
Get faster more accurate cutting results by keeping
cutters clean and sharp. Remove all accumulated pitch
and gum from cutters after each use.
When sharpening cutters, sharpen only the inside of the
cutting edge. Never grind the outside diameter. Be sure
when sharpening the end of a cutter to grind the
clearance angle the same as originally ground.
PROPER CARE OF COLLET
From time to time, it also becomes necessary to clean
your collet and collet nut. To do so, simply remove collet
nut from the collet and clean the dust and chips that have
Collected. Then return the collet nut to its original position.
GENERAL
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.
WARNING:
When servicing use only identical Ryobi
replacement parts. Use of any other parts may
create a hazard or cause product damage.

Use clean cloths to remove dirt, carbon dust, etc.
When electric tools are used on fibreglass boats, sports
cars, wallboard, spackling compounds or plaster, it has
been found that they are subject to accelerated wear and
possible premature failure, as the fiberglass chips and
grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently it is not recommended
that this tool be used for extended work on any fiberglass
material, wallboard, spackling compounds or plaster.
During any use on these materials, it is extremely
important that the tool is cleaned frequently by blowing
with an air jet.
LUBRICATION
All of the bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of the
unit under normal operating conditions. Therefore, no
further lubrication is required.
BRUSH REPLACEMENT (Fig. 11)
Your trimmer has externally accessible brush
assemblies that should periodically be checked for
wear. Proceed as follows when replacement is
required:
WARNING:
Failure to unplug your trimmer could result in
accidental starting causing serious injury.
WARNING:
Do not at anytime let brake fluids, fuel,
petroleum-based products, penetrating oils,
etc. come in contact with plastic parts. They
contain chemicals that can damage,
weaken or destroy plastic.
WARNING:
Always wear safety goggles or safety
glasses with side shields during power tool
operation or when blowing dust. If operation
is dusty, also wear a dust mask.
UNPLUG YOUR TRIMMER.
