MAINTENANCE
WARNING:
Always wear safety
goggles or safety glasses with side shields
during power tool operations, or when
blowing dust. If operation is dusty, also wear
a dust mask.
It has been found that electric tools are
subject to accelerated wear and possible
premature failure when they are used to
work on fiber glass boats and sports cars,
wallboard, spackling compounds or
plaster. The chips and grindings from these
materials are highly abrasive to electrical
tool parts, such as bearings, brushes,
commutators, etc. Consequently, it is not
recommended that this tool be used for
extended work on any fiberglass mate-
rial, wallboard, spackling compound or plas-
ter. During any use on these materials, it is
extremely important that the tool is cleaned
frequently by blowing with an air jet
WARNING:
Do not at any time let
brake fluids, gasoline, petroleum-based
products, penetrating oils, etc. come in
contact with plastic parts. Chemicals can
damage, weaken or destroy plastic, which
may result in serious personal injury.
Periodic maintenance allows for long life
and trouble-free operation. A cleaning,
lubrication and maintenance schedule should
be maintained. As a common preventive
maintenance practice, follow these
recommended steps:
1. When work has been completed, clean
the tool to allow smooth functioning of
the tool over time.
2. Use clean damp cloths to wipe the tool.
3. Check the state of all electrical cables.
4. Keep the motor air openings free from
oil, grease and sawdust or woodchips,
and store tool in a dry place.
5. Be certain that all moving parts are well
lubricated, particularly after lengthy
exposure to damp and/or dirty conditions.
LUBRICATION
All of the bearings in this tool are lubricated
with a sufficient amount of high-grade
lubricant for the life of the tool under normal
operating conditions. Therefore, no further
lubrication is required.
WARNING:
For your safety, always
turn off switch and remove battery pack
before performing any maintenance
or cleaning.
GENERAL MAINTENANCE
The tool may be cleaned most effectively
with compressed dry air. Always wear safety
goggles when cleaning tools with
compressed air.
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, dust, oil,
grease, etc.
WARNING:
When servicing, use
only identical MASTERFORCE replacement
parts. Use of any other parts may create a
hazard or cause product damage. To ensure
safety and reliability, all repairs should be
performed by a qualified service technician
at an Authorized Service Center.
