GENERAL SAFETY WARNINGS
WARNING:
Before using this tool or any of its accessories, read this manual and follow all Safety
Rules and Operating Instructions. The important precautions, safeguards and
instructions appearing in this manual are not meant to cover all possible situations.
It must be understood that common sense and caution are factors which cannot be
built into the product.
EYE, EAR & LUNG PROTECTION
SYMBOL MEANING
ALWAYS WEAR EYE PROTECTION THAT CONFORMS WITH CSA
Z94.3 or ANSI SAFETY STANDARD Z87.1
FLYING DEBRIS can cause permanent eye damage. Prescription
eyeglasses ARE NOT a replacement for proper eye protection.
Non-compliant eyewear can cause serious injury if broken during
the operation of a power tool.
Use hearing protection, particularly during extended periods of
operation of the tool, or if the operation is noisy.
WEAR A DUST MASK THAT IS DESIGNED TO BE USED WHEN
OPERATING A POWER TOOL IN A DUSTY ENVIRONMENT.
Dust that is created by power sanding, sawing, grinding, drilling, and
other construction activities may contain chemicals that are known
to cause cancer, birth defects, or other genetic abnormalities. These
chemicals include:
• Lead from lead-based paints
• Crystalline silica from bricks, cement, and other masonry products
• Arsenic and chromium from chemically treated lumber.
The level of risk from exposure to these chemicals varies, according to
how often this type of work is performed. In order to reduce exposure
to these chemicals, work in a well-ventilated area, and use approved
safety equipment, such as a dust mask that is specifically designed to
filter out microscopic particles.
To avoid electrical hazards, fire hazards or damage to the tool,
use proper circuit protection.
This tool is wired at the factory for 120 Volts AC operation. It must be

GENERAL SAFETY RULES
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 a ground fault circuit interrupter
(GFCI) protected supply. Use of a ground fault circuit interrupter (GFCI) 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.
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.

5
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.
Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing,
and gloves away from moving parts. Loose clothes, jewellery 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.
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.
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,
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.
BATTERY TOOL USE AND CARE
1. Charge a rechargeable battery using only the charger recommended by the
manufacturer. Chargers are often designed for a particular type of rechargeable
battery unit. There is a risk of fire if a battery charger specified for a particular
type of battery is used with other batteries.
2. Only the rechargeable battery units supplied are to be used with an electrical
power tool. The use of other rechargeable battery units may lead to the danger
of injury or fire.
3. When they are not being used, store rechargeable battery units away from
paperclips, coins, keys, nails, screws or other small metal objects that could
cause the contacts to be bridged. Short circuiting the contacts of a rechargeable
battery unit may result in heat damage or fire.

OPERATING
ON/OFF SWITCH
To turn the sander ON, ensure battery is charged and inserted into the back of
position. (Fig. 2)
Fig 2
SPEED ADJUSTMENT
Your orbital sander is equipped with a speed setting wheel. To set speed, turn speed
wheel to desired speed setting. Note, the lowest number equals the lowest speed
setting. The highest number is the highest speed.
SANDPAPER SELECTION
Selecting the correct grit and type of sandpaper is extremely important in achieving
a high- quality sanded finish. Aluminum oxide, silicon carbide and other synthetic
abrasives are best for power sanding. Natural abrasives such as flint and garnet are
too soft for economical use in power sanding. In general, coarse grit will remove the
most material and finer grit will produce the best finish in all sanding operations.
The condition of the surface to be sanded will determine which grit will do the best
job. If the surface is rough, start with a coarse grit and sand until the surface is
uniform. Medium grit may then be used to remove scratches left by the coarser grit.
Fine grit should be used for finishing the surface. Always continue sanding with each
grit until the surface is uniform.
WARNING: Always wear safety goggles or safety glasses with side shields when
operating your sander. Failure to do so could result in foreign objects being thrown
into your eyes resulting in possible serious eye damage.
Always wear an appropriate dust mask and hearing protection when
using your sander.

WARNING:
For safety reasons, the operator must read the sections of this Owner’s
Manual entitled “GENERAL SAFETY WARNINGS”, “POWER TOOL
SAFETY”, “SPECIFIC SAFETY RULES”, “EXTENSION CORD SAFETY”
and “SYMBOLS” before using this cut-out tool.
Verify the following every time the pad sander is used:
1. Safety glasses and dust mask are being worn.
2. Hearing protection is being worn.
3. Sandpaper is the correct type for the job.
Sandpaper is in good condition and is properly installed.
Failure to adhere to these safety rules can greatly increase the
chances of serious injury.
SANDING
Clamp or otherwise secure your workpiece to prevent it from moving under the
sander while being sanded.
WARNING: An unsecured workpiece could be thrown toward the operator
causing injury.
Place the sander on the workpiece so that the complete sandpaper surface is in
contact with the workpiece. Turn the sander ON by pressing on the side of the
ON/OFF switch. Move the sander slowly over workpiece making successive passes
in parallel lines, circles or crosswise movements.
Upon completion of the sanding operation, turn the sander OFF by pressing on the
opposite side of the ON/OFF switch. Wait until the sanding pad comes to a complete
stop before removing it from the workpiece.
WARNING: Your sander should only be turned ON when the entire surface
of the sanding pad is in contact with the workpiece. Failure to follow this sanding
procedure could result in loose sandpaper which could result in possible injury.
NOTE: Hold the sander using the grip on top of the sander. Be careful NOT to cover
the motor cooling vents with your hand. Motor damage may occur from over heating
if the cooling vents are covered.
DO NOT FORCE THE SANDER. The weight of the sander usually provides
adequate pressure. Let the sander and the sandpaper do the work. Applying added
pressure will slow the motor, increase the wear on the sandpaper and greatly reduce
the sander speed. Motor damage may occur if excessive downward pressure is
applied. It will also create an inferior finish on sanded work. Any finish or resin on
wood will soften from the frictional heat, causing the sandpaper to become clogged
very quickly. Do not sand in one spot too long as the sander’s rapid action may
remove too much material, making the surface uneven. Extended periods of sanding
may tend to overheat the motor. If this occurs, turn sander OFF, wait until the
sanding pad comes to a complete stop and remove it from the workpiece.
Check to make sure your hand has not been covering the cooling vents. Let the
motor cool before continuing the sanding operation.

the workpiece.
WARNING: DO NOT attempt to modify tools or create accessories.
Any such alteration or modification is misuse and could result in a hazardous
condition leading to possible serious injury. It will also void the warranty.
Remove accumulated dust and debris regularly using a soft DRY brush.
It has been found that electric 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 highly abrasive to electric tool parts such as bearings, brushes,
commutators, etc. Consequently, it is not recommended that this tool be used
for extended work on any fiberglass material, wallboard, spackling compounds or
plaster. During any use on these materials it is extremely important that the tool is
cleaned frequently by blowing it out with an air jet.
WARNING: Always wear safety goggles or safety glasses with side shields
during all sanding operations. It is critical that you also wear safety goggles or
safety glasses with side shields and a dust mask while blowing dust out of the
cut-out tool with an air jet. Failure to take these safety precautions could result
in permanent eye or lung damage.
