MAINTENANCE
WARNING:
Before inspecting, cleaning, or performing any
maintenance, make sure the switch is in the
OFF
(O)
position, wait for all moving parts to stop, and
disconnect from the power supply. Failure to follow
these instructions can result in death, serious
personal injury, or property damage.
WARNING:
Always wear eye protection with side shields
marked to comply with ANSI Z87.1. Failure to do
so could result in objects being thrown into your
eyes, resulting in possible serious injury.
WARNING:
When servicing use only identical replacement
parts. Use of any other parts may create a hazard
or cause product damage.
GENERAL MAINTENANCE
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:
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.
Electric tools used on fiberglass material, wallboard, spack-
ling compounds, or plaster are subject to accelerated wear
and possible premature failure because the fiberglass chips
and grindings are highly abrasive to bearings, brushes,
commutators, etc. Consequently, we do not recommended
using this tool for extended work on these types of materials.
However, if you do work with any of these materials, it is ex-
tremely important to clean the tool using compressed air.
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 lubrica-
tion is required.
POWER SUPPLY CORD REPLACEMENT
If replacement of the power supply cord is necessary, this
must be done by an authorized service center in order to
avoid a safety hazard.
CLEANING THE BITS
Get faster more accurate cutting results by keeping
bits clean and sharp. Remove all accumulated pitch and
gum from bits after each use. When sharpening bits, sharpen
only the inside of the cutting edge. Never grind the outside
diameter. When sharpening the end of a bit, be sure to grind
the clearance angle the same as originally ground.
CLEANING THE COLLET
From time to time, it becomes necessary to clean the 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.
