MAINTENANCE
WARNING:
When servicing, use only identical replacement
parts. Use of any other part 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, 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.
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 14 is recommended for
an extension cord 25 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.
WARNING:
Keep extension cords away from the cutting area
and position the cord so that it will not get caught
on lumber, tools, etc., during cutting operation. Fail-
ure to heed this warning may result in serious per-
sonal injury.
CAUTION:
Check extension cords before each use. If dam-
aged, replace immediately. Never use tool with a
damaged cord since touching the damaged area
could cause electrical shock resulting in serious
injury.
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:
To ensure safety and reliability, all repairs should
be performed by a qualified service technician at a
Authorized Service Center to avoid risk of personal
injury.
