MAINTENANCE
When electric tools are use on fiberglass 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.
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.
WARNING:
When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or cause product
damage.
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. Use clean cloths
to remove dirt, carbon dust, etc.
WARNING:
Do not at any time let brake fluids, gasoline, petroleum-
based products, penetrating oils, etc. come in contact
with plastic parts. They contain chemicals that can
damage, weaken, or destroy plastic.
PROPER CARE OF CUTTERS
Get faster and 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
collet and clean the dust and chips that have collected. Then
return collet nut to its original position. Tighten collet nut on
collet without a cutter installed.
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.
