GENERAL SAFETY WARNINGS

5
WARNING: Read all safety warnings and
all instructions. Failure to follow the warnings
and instructions may result in electric shock, fire
and/or serious injury.
Save all warnings and instructions for future
reference.
Work area safety
Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. Power tools
create sparks which may ignite the dust or
fumes.
Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
Electrical safety
Power tool plugs must match the outlet.
Never modify the plug in any way. Do not
use any adapter plugs with earthed
(grounded) power tools. Unmodified plugs and
matching outlets will reduce risk of electric
shock.
Avoid body contact with earthed or
grounded surfaces such as pipes, radiators,
ranges and refrigerators. There is an
increased risk of electric shock if your body is
earthed or grounded.
Do not expose power tools to rain or wet
conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord
for carrying, pulling or unplugging the power
tool. Keep cord away from heat, oil, sharp
edges or moving parts. Damaged or
entangled cords increase the risk of electric
shock.
When operating a power tool outdoors, use
an extension cord suitable for outdoor use.
Use of a cord suitable for outdoor use reduces
the risk of electric shock.
If operating a power tool in a damp location
is unavoidable, use a residual current device
(RCD) protected supply. Use of an RCD
reduces the risk of electric shock.
Personal safety
Stay alert, watch what you are doing and use
common sense when operating a power tool.
Do not use a power tool while you are tired
or under the influence of drugs, alcohol or
medication. A moment of inattention while
operating power tools may result in serious
personal injury.
Use personal protective equipment. Always
wear eye protection. Protective equipment
such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
Prevent unintentional starting. Ensure the
switch is in the off-position before
connecting to power source and/or battery
pack, picking up or carrying the tool.
Carrying power tools with your finger on the
switch or energizing power tools that have the
switch on invites accidents.
Remove any adjusting key or wrench before
turning the power tool on. A wrench or a key
left attached to a rotating part of the power tool
may result in personal injury.
Do not overreach. Keep proper footing and
balance at all times. This enables better
control of the power tool in unexpected
situations.

PERSONAL SAFETY –cont’d
Dress properly. Do not wear loose clothing
or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose
clothes, jewelry or long hair can be caught in
moving parts.
If devices are provided for the connection of
dust extraction and collection facilities,
ensure these are connected and properly
used. Use of dust collection can reduce dust-
related hazards.
Do not let familiarity gained from frequent
use of tools allow you to become
complacent and ignore tool safety
principles. A careless action can cause severe
injury within a fraction of a second.
Power tool use and care
Do not force the power tool. Use the correct
power tool for your application. The correct
power tool will do the job better and safer at the
rate for which it was designed.
Do not use the power tool if the switch does
not turn it on and off. Any power tool that
cannot be controlled with the switch is
dangerous and must be repaired.
Disconnect the plug from the power source
and/or the battery pack from the power tool
before making any adjustments, changing
accessories, or storing power tools. Such
preventive safety measures reduce the risk of
starting the power tool accidentally.
Store idle power tools out of the reach of
children and do not allow persons unfamiliar
with the power tool or these instructions to
operate the power tool. Power tools are
dangerous in the hands of untrained users.
Maintain power tools. Check for
misalignment or binding of moving parts,
breakage of parts and any other condition
that may affect the power tool’s operation. If
damaged, have the power tool repaired
before use. Many accidents are caused by
poorly maintained power tools.
Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to
control.
Use the power tool, accessories and tool bits
etc. in accordance with these instructions,
taking into account the working conditions
and the work to be performed. Use of the
power tool for operations different from those
intended could result in a hazardous situation.
Keep handles and grasping surfaces dry,
clean and free from oil and grease. Slippery
handles and grasping surfaces do not allow for
safe handling and control of the tool in
unexpected situations.
Service
Have your power tool serviced by a qualified
repair person using only identical
replacement parts. This will ensure that the
safety of the power tool is maintained.
POWER TOOL SAFETY
SAVE THESE INSTRUCTIONS FOR REFERENCE

WARNING: Know your rotary tool. Do
not plug the tool into the power source until
you have read and understand this
Instruction Manual. Learn the tool’s
applications and limitations, as well as the
specific potential hazards related to this tool.
Following this rule will reduce the risk of electric
shock, fire, or serious injury.
Always wear eye protection. Any
power tool can throw foreign
objects into your eyes and cause
permanent eye damage.
ALWAYS wear safety goggles (not glasses) that
comply with ANSI safety standard Z87.1.
Everyday glasses have only impact resistant
lenses. They ARE NOT safety glasses.
WARNING: Glasses or goggles not in
compliance with ANSI Z87.1 could cause
serious injury when they break.
Hold tool by insulated gripping surfaces
when performing an operation where the
cutting tool may contact hidden wiring or its
own cord. Contact with a “live” wire will make
exposed metal parts of the tool “live” and shock
the operator.
Always make sure the work surface is free
from nails and other foreign objects. Cutting
into a nail can cause the bit and the tool to jump
and damage the bit.
Never hold the workpiece in one hand and
the tool in the other hand when in use. Never
place the hands near or below the cutting
surface. Clamping the material and guiding the
tool with both hands is much safer.
Never lay workpiece on hard surfaces like
concrete, stone, etc. Protruding cutting bit may
cause the tool to jump
Always wear safety goggles and dust mask.
Use only in well-ventilated area. Using
personal safety devices and working in a safe
environment reduces risk of injury.
After changing the bits and accessories or
making adjustments, make sure the collet
nut and any other adjustment devices are
securely tightened. Loose adjustment devices
will be violently thrown.
Always use the correct collet size. If the collet
size is larger than the accessory shank size it
will not grip the shank properly, leading to
possible injury to the operator or damage to the
tool.
Always check accessory bits, grinding
stones, cut-off wheels etc. for damage
before each use. Damaged accessories can
break during use and cause serious injury.
Never use dull or damaged bits. Sharp bits
must be handled with care. Damaged bits can
snap during use. Dull bits require more force to
push the tool, possibly causing the bit to break.
Never touch the bit during or immediately
after use. After use the bit is too hot to be
touched by bare hands.

WARNING: Keep the extension cord
clear of the working area. Position the cord so
it will not get caught on the workpiece, tools or
any other obstructions while you are working
with the power tool.
Make sure any extension cord used with this
tool is in good condition. When using an
extension cord, be sure to use one of heavy
enough gauge to carry the current the tool will
draw. An undersized cord will cause a drop in
line voltage resulting in loss of power and
overheating.
The table to the right shows the correct size to
use according to cord length and nameplate
ampere rating. If in doubt, use the next heavier
gauge. The smaller the gauge number the
heavier the cord.
Be sure your extension cord is properly wired
and in good condition. Always replace a
damaged extension cord or have it repaired by a
qualified electrician before using it. Protect your
extension cord from sharp objects, excessive
heat and damp or wet areas.
Use a separate electrical circuit for your power
tools. This circuit must not be less than 14
gauge wire and should be protected with either
a 15 A time delayed fuse or circuit breaker.
Before connecting the power tool to the power
source, make sure the switch is in the OFF
position and the power source is the same as
indicated on the nameplate. Running at lower
voltage will damage the motor.

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.
