UDOS 51E –Operator’s Manual v1.6
Prior to using, read, understand
and follow all safety warnings,
cautions, instructions, and specifications provided with
this power tool. Failure to follow all of the instructions
provided with this power tool may result in significant
property damage, personal injury, or death.
Do not operate the tool in the
presence of flammable vapors,
gases, liquids or dust. Powered tools may create sparks
at any time the tool plugged into a power source,
potentially resulting in an explosion.
Work in a neat, clean and well-lit area. Clutter and dimly
lit areas can result in accidents.
Keep bystanders away during operation. Proper personal
protective equipment must be worn by the tool operator
and any bystanders.
This tool must be plugged into
an outlet that exactly matches
the plug provided with the tool. NEVER MODIFY THE
POWER PLUG. Confirm the outlet and circuit providing
power to the tool is of sufficient capacity.
Do NOT expose or operate the tool in wet conditions.
Water entering the tool, or standing in or near water
while the tool is plugged in, greatly increases the risk of
electric shock.
Do NOT abuse the power cord. Never carry, swing, or
drag the tool by the power cord. DO NOT unplug the tool
by pulling on the power cord.
Inspect the power cord for any damage or degradation
such as cracks, splits, and swelling prior to use. Using the
tool with a damaged or degraded cord increases the risk
of electric shock.
The use of Ground Fault Circuit Interrupter (GFCI)
protected power source is recommended. A GFCI circuit
reduces the risk of electric shock.
Do NOT use this tool if you are
tired, or under the influence of
drugs, medications, or alcohol. Operating the tool while
impaired can result in serious personal injury or death.
Use Personal Protective Equipment (PPE). Always wear
ANSI Z87.1 protective eyewear and hearing protection
when using the tool. Additional PPE such as non-skid
safety shoes, vibration reduction gloves, particulate mask,
respirator, and a hardhat used when conditions indicate,
can greatly reduce the risk of personal injury.
Never carry the tool with you finger on or near the
trigger. Unintentional starting of the tool can result in
personal injury. Always confirm the trigger is in the off
(non-locked) position when plugging the tool into a power
source.
Dress properly. Do NOT wear loose fitting clothing, or
jewelry while operating the tool. Tie back long hair.
Loose clothing, jewelry, and hair can very quickly become
caught in the moving parts of the tool.
Do NOT overreach with the tool. Never operate the tool
with one hand. Always maintain proper control of the
tool by using both hands. Losing control of the tool can
result in serious personal injury.
Do NOT overload the tool. Select the proper size tool and
accessories for the job. Failure to do so can damage the
tool and result in an unsafe work condition.
Inspect the tool before use. Ensure the power switch
operates correctly, the power cord is in good condition,
and the mode adjustment mechanism is operating
smoothly.
Use only specified accessories. The use of unspecified
accessories may compromise performance, possibly
result in an unsafe work condition, and will void the
warranty.
This power tool is a combination Dual Action and Rotary
Polisher/Sander. It is intended for use in finish
correction of painted and gel-coated surfaces. Failure to
adhere to the following instructions may result in
significant property damage, serious personal injury, or
death. Operations such as sawing,
grinding, wire brushing, or
cutting-off are not authorized. Performing operations for
which a tool is not designed may result in an unsafe work
condition.
Use only accessories recommended for this power tool.
Use of non-authorized accessories will result in
substandard performance and may lead to an unsafe
work condition. Wear personal protective
equipment. Depending on the
application, use a face shield, with safety goggles or safety
glasses. As appropriate, wear dust mask, hearing
protectors, gloves and workshop apron capable of
stopping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris
generated by various operations. The dust mask or
respirator must be capable of filtrating particles
generated by your operation. Prolonged exposure to high
intensity noise may cause hearing loss.
Inspect tool and accessories
before use. The use of damaged,
cracked, or otherwise compromised accessories can
result in breakage and thrown hi-speed fragments. After
inspecting and installing an accessory, in an area free of
bystanders, with rotating plane of the tool pointed away,
run the tool at its maximum speed for one minute to
confirm proper operation. If any thrown fragments, or
excessive imbalance is encountered, immediately stop
the tool and inspect the tool and accessories thoroughly.

Do NOT cover the cooling vents
with your hand during
operation. Obstructed vents can lead to motor
overheating, resulting a thermal shutdown and potential
tool damage. Beware of tool kickback.
Kickback is a result of misuse and
can occur when tool rotation is suddenly stopped by an
obstruction. A strong opposite direction reaction torque
is then transmitted through the tool body to the operator.
This can cause serious personal injury. To avoid kickback
avoid using the tool in areas where the rotating
accessories can become caught or pinched, such as
around mirrors, antennas, panel gaps and sharp contours.
The secure use of both hands on the tool in the designed
positions will minimized the risk of personal injury if
kickback occurs. Never use one hand to operate the tool.
Do not allow any loose portion
of a polishing bonnet or its
attachment strings to spin freely. Tuck away or trim any
loose attachment strings. Loose and spinning attachment
strings can entangle your fingers resulting in a severe
laceration or even amputation. Loose attachment strings
can snag on the workpiece resulting in kickback.
Position the cord clear of the spinning accessory. If you
lose control, the cord may be cut or snagged and your
hand or arm may be pulled into the spinning accessory.
Never lay the power tool down until the accessory has
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your
control.
Do not run the power tool while carrying it at your side.
Accidental contact with the spinning accessory could snag
your clothing, pulling the accessory into your body

If an extension cord is used,
ensure the extension cord gauge
is adequate for the tool. The UDOS tool is double
insulated thus the use of both 2 and 3 conductor
extension cords is permitted. If the standard UDOS power
cord is not long enough for the application, use the

The tool is equipped with load sensing. If an overload
condition occurs, the motor will stop pausing for about 1-
2 seconds, then try to restart. If after 6 restarts the
overload condition still exists, the motor will shut down.
Release the trigger, and allow the tool to cool for 3
minutes before continuing.
The rotational speed of the tool is adjusted using the
scroll thumb wheel on top of the handle. The following
table provides the approximate spindle RPM for each
setting of the thumb wheel.
The 6 white Stall-Aware®
marks on the top of the
UDOS backing plate
provide a convenient
indication of the orbital
rotation of the pad. During
normal operation the
Stall-Aware® markings will
rotate clockwise and
appear similar to the
pattern shown.
Applying more pressure
will cause the pattern to
shift to a series of clockwise
rotating circles as shown,
indicating a pending stall.
If excessive downward
pressure is applied, the
circle pattern will appear to
stop then rotate counter
clockwise, indicating a full
stall. Decrease the pressure
on the tool to restore proper
orbital action.

To reduce the risk of injury,
unplug the tool before perform
any inspection and/or cleaning.
Inspection
Become familiar with the proper performance behavior of
the tool. Periodically inspect the tool for issues such as
undue noise, excessive vibration, misalignment or binding
of moving parts, breakage of parts, or any other condition
that may affect the tool operation. Return the tool to an
authorized service center for repair.
Cleaning
Clean dust and debris from vents. Keep handles clean,
dry and free of oil or grease. To avoid the risk of shock,
Do NOT spray cleaners directly on the tool. Instead apply
the cleaner to a cloth first, then wipe the tool. Use only
mild soap and a damp cloth to clean, since certain
cleaning agents and solvents are harmful to plastics and
other insulated parts. Some of these include gasoline,
turpentine, lacquer thinner, paint thinner, chlorinated
cleaning solvents, ammonia and household detergents
containing ammonia. Never use flammable or
combustible solvents around tools. To avoid the risk of
shock, Do NOT spray cleaners directly on the tool.
