MAINTENANCE
GENERAL
All parts represent an important part of the double
insulation system and should be serviced only at an
authorized service center.
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, petro-
leum-based products, penetrating oils, etc. come in
contact with plastic parts. They contain chemicals that
can damage, weaken or destroy plastic.
It has been found that electric tools are subject to
accelerated wear and possible premature failure when
they are used on fiberglass boats, sports cars, wallboard,
spackling compounds, or plaster. The chips and grindings
from these materials are highly abrasive to electric tool
parts, such as 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.
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.
DOUBLE INSULATION
Double insulation is a concept in safety in electric power
tools, which eliminates the need for the usual three-wire
grounded power cord. All exposed metal parts are isolated
from the internal metal motor components with protecting
insulation. Double insulated tools do not need to be
grounded.
IMPORTANT
Servicing of a tool with double insulation requires extreme
care and knowledge of the system and should be
performed only by a qualified service technician. For
service, we suggest you return the tool to your nearest
authorized service center for repair. Always use original
factory replacement parts when servicing.
EXTENSION CORDS
The use of any extension cord will cause some loss of
power. To keep the loss to a minimum and to prevent
tool overheating, use an extension cord that is heavy
enough to carry the current the tool will draw.
A wire gage size (A.W.G.) of at least 16 is recommended
for an extension cord 100 feet or less in length. When
working outdoors, use an extension cord that is suitable
for outdoor use. The cord's jacket will be marked WA.
CAUTION:
Keep extension cords away from the drilling area and
position the cord so that it will not get caught on lum-
ber, tools, etc., during drilling operation.
WARNING:
Check extension cords before each use. If damaged
replace immediately. Never use tool with a damaged
cord since touching the damaged area could cause
electrical shock resulting in serious injury.
Extension cords suitable for use with your drill are
available at your nearest authorized service center.
WARNING:
When servicing use only identical Ryobi replacement parts. Use of any other parts may create a hazard or
cause product damage.
