CALIFORNIA PROPOSITION 65 WARNING
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities may contain
chemicals, including lead, known to the State of California to cause cancer, birth defects, or other reproductive
harm. Wash hands after handling.
Some examples of these chemicals are:
• Lead from lead-based paints.
• Crystalline silica from bricks, cement, and other masonry products.
• Arsenic and chromium from chemically treated lumber.
Your risk from these exposures varies depending on how often you do this type of work. To reduce your ex-
posure to these chemicals, work in a well-ventilated area with approved safety equipment such as dust masks
specially designed to filter out microscopic particles.
GENERAL SAFETY RULES

DOUBLE INSULATION
Double insulation is a concept in safety in electric power tools, where two systems of insulation
are provided. This eliminates the need for the usual three-wire grounded power cord. All exposed
metal parts are isolated from the internal metal motor components with protecting insulation.
Double insulated tools do not need to be grounded.
WARNING: The double insulated system is intended to protect the user from electric shock re-
sulting from a break in the tool’s internal insulation. Observe all normal safety precautions to avoid
electrical shock.
1. REPLACEMENT PARTS
When servicing use only identical replacement parts.
NOTE: Servicing of a product with double insulation requires extreme care and knowledge of the system and
should be performed only by a qualified service technician. For service, we suggest bringing the product to you
nearest authorized service center for repair. Always use original factory replacement parts when servicing.
2. POLARIZED PLUGS
To reduce the risk of electric shock, this equipment has a polarized plug (one blade is wider than the other).
This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If
it still does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
3. SERVICE AND REPAIR. To avoid danger, electrical appliances must only be repaired by qualified service
technician using original replacement parts; otherwise this may result in considerable damage to the user.
WARNING: To avoid electrocution, do not use in wet or damp areas or expose to rain.
GUIDELINES FOR USING EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw.
An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table below
shows the correct size to be used according to cord length and nameplate ampere rating. When in doubt, use a
heavier cord. The smaller the gauge number, the heavier the cord.
ELECTRICAL INFORMATION
Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension
cord or have it repaired by a qualified person before using it. Protect your extension cords from sharp objects,
excessive heat and damp/wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be pro-
tected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is
in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate.
Running at a lower voltage will damage the motor.

WARNING: Read and thoroughly understand all instructions and safety information before operat-
ing this rotary tool. Failure to do so may cause serious injury.
OPERATION
OPERATING THE ROTARY TOOL
As with all power equipment, a rotary tool can be dangerous if it is not assembled or used properly. Do not
operate this power tool if you have doubts or questions regarding operation safety. Call our customer service
department at 1-800-232-1195 M-F 8-5 CST to address your questions or concerns.
WARNING: Always wear ANSI Z87.1-approved safety glasses, safety gloves and suitable work cloth-
ing. Do not wear jewelry, neckties or other loose clothing which could get caught in moving parts. Hold
the tool away from your face and body in case parts and chips fly out unexpectedly during operation.
WARNING: Do not start or operate this tool in the presence of flammable liquids or gases. Sparks
generated by the rotary tool could ignite these flammable materials.
1. Inspect the tool for any damage before use. Immediately discard any accessories with bent shafts or any other
damage. Make sure that the ventilation slots on the tool are not obstructed, otherwise the motor may overheat.
2. The power switch is located on the underside of the handle. To switch on the tool, flip it to I (the ON posi-
tion). To switch off the tool, flip the switch to O (the OFF position). Be certain the tool is in the OFF position
when not in use and during all maintenance activities.
3. Set the suitable speed for your operation. Turn on the tool and let the motor reach full speed. Slowly lower
the accessory bit onto the workpiece and guide the tool with light, even pressure.
NOTE: Do not exert excessive pressure on your tool as it may damage your workpiece and the accessory bit.
Let the tool do the work. For better results, make several progressive passes until the desired cutting depth or
finish is achieved.
4. Lift the tool away from the workpiece and turn OFF the switch. Wait for the tool to come to a complete stop
before setting it down. Do not touch the rotary accessory or workpiece immediately after operation as they can
be very hot. Follow the instructions on the next page for properly maintaining your tool and accessories.
ADJUSTING THE SPEED OF THE ROTARY TOOL (Fig. 15)
The variable speed adjustment wheel on the top of the rotary tool is used to set
the desired rotation speed. The speed for your rotary tool ranges from 8,000
to 35,000 RPM. To increase the speed, turn the wheel forward to a higher
number. To decrease speed, turn the wheel backwards to a lower number.
Set the suitable speed for your operation, workpiece and accessories:
• Use slow speeds for plastics, ceramics, precious metals and low-melting point materials to prevent damag-
ing the material. All brushing applications and delicate polishing require slow rotary speeds lower than 15,000
RPM.
• Use higher speeds when working on wood, metal and glass. Drilling, carving, cutting, routing, shaping or rab-
bets are generally performed more efficiently at faster rotary speeds.
As a general rule, larger attachments should be used at a lower speed. The best way to determine the suitable
speed is to test on a scrap piece of similar material, observe the results and adjust the speed accordingly.
