WARNING: When servicing, use only
identical replacement parts. The use of any
other part may create a hazard or damage the
rotary tool.
Do not abuse power tools. Abusive practices
can damage the tool and the workpiece.
WARNING: Do not attempt to modify this
rotary tool or to create accessories. Any such
alteration or modification is considered to be
misuse, and could result in a hazardous
condition that may lead to serious injury. Doing
so will also void the warranty.
CLEANING
Do not use solvents to clean plastic parts. Many
plastics are susceptible to damage from various
types of commercial solvents. Use a clean cloth
to remove dirt, dust, oil, grease, etc.
WARNING: Do not allow brake fluids,
gasoline, petroleum-based products, penetrating
oils, etc. to come into contact with plastic parts.
These substances contain chemicals that can
damage, weaken, or destroy plastic.
Power tools are subjected to accelerated wear
and possible premature failure when they are
used on fiberglass boats and sports cars,
wallboard, spackling compounds, or plaster. The
chips and grindings from these materials are
extremely abrasive to some parts of power
tools, including bearings, brushes, commutators,
etc. Therefore, it is recommended that this tool
not be used for extended work on any fiberglass
material, wallboard, spackling compound, or
plaster. If this rotary tool is used on these
materials for an extended period, it must be
cleaned frequently by blowing it out with an air
jet.
WARNING: Wear safety goggles or
safety glasses that have side shields whenever
performing any operation with a rotary tool. It is
also critical to wear safety goggles or safety
glasses that have side shields, as well as a dust
mask, when blowing dust out of the tool using
an air jet. Failure to observe these safety
precautions could result in permanent eye or
lung damage.
LUBRICATION
All of the bearings in this rotary tool have been
lubricated with a sufficient quantity of high-grade
lubricant for the life of the tool under normal
conditions. No further lubrication is required.
REPLACING MOTOR BRUSHES
The carbon motor brushes will wear down and
require replacing. The time intervals between
replacements will vary depending upon the type
of materials being cut and the hours of use. It is
recommended that the brushes be checked
after each 10 hours of use. When the length of
the carbon brush reaches 1/4" (6.35 mm), the
brushes should be replaced.
1. Remove the motor brush caps (1) with a
small slot screwdriver by turning them counter
clockwise (Fig. 12).
2. Remove the brush & spring assemblies (2).
3. Insert new brush & spring assemblies.
4. Reinstall the brush caps.
NOTE: Make sure the brush caps are not
cross threaded and do not over tighten.
