SAFETY GUIDELINES
WARNING!
Safety symbols in this instruction manual are used to flag possible
dangers. The safety symbols and their explanations require your full
understanding. The safety warnings do not, by themselves, eliminate
any danger, nor are they substitutes for proper accident prevention
measures.
WARNING!
This Safety Alert Symbol indicates caution, warning, or danger. Failure
to obey a safety warning can result in serious injury to yourself or
others. To reduce the risk of injury, fire, or electric shock, always follow
the safety precautions.

GENERAL POWER TOOL SAFETY WARNINGS
WARNING!
Read all safety warnings and 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.
The term “power tool” in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
WORK AREA SAFETY
• Keep the 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.
SAFETY GUIDELINES

model no. 054-7276-4 | contact us 1-888-670-6682
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 ground
ed.
• 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 ground-fault
circuit interrupter (GFCI) protected supply. Use of a 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.
• 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 energising 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.
• 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 that these are connected and properly used. Use of these
devices can reduce dust-related hazards.
SAFETY GUIDELINES

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 more safely 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, 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.
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.
SAFETY GUIDELINES FOR THE CORDED 1/4-SHEET ORBIT SANDER
• Hold power tools by insulated gripping surfaces when performing an
operation where the tool may contact hidden wiring or its own cord. Contact
with a “live” wire may make exposed metal parts of the power tool “live” and
could give the operator an electric shock.
• Use clamps or another practical way to support and secure the workpiece to
a stable platform. Holding the work by hand or against your body is unstable
and may lead to loss of control.
• Always wear eye protection and a dust mask for dusty applications and when
absorbed by your eyes and inhaled easily and may cause health complications.
Protect your hearing while using this tool.
SAFETY GUIDELINES

8
model no. 054-7276-4 | contact us 1-888-670-6682
• Empty the dust canister frequently and after completion of sanding. Be
extremely careful of dust disposal; materials in fine particle form may be
explosive. Do not throw sanding dust on an open fire. Spontaneous combustion
may, in time, result from the mixture of oil or water with dust particles.
• Do not wet sand with this sander. Liquid entering the motor housing is an
electrical shock hazard.
• The label on your tool may include the following symbols. The symbols and
their definitions are as follows:
V ..................... Volts
A ..................... Amperes
Hz ................... Hertz
W .................... Watts
min ................. Minutes

SANDING
This sander can be used for most sanding operations on materials such as wood,
plastic and painted surfaces. Do not use the sander for wet sanding.
1. Plug the sander into the power source.
2. Place the sander on the workpiece so that the sandpaper is fully in contact
with the workpiece.
3. Start the sander.
4. For best sanding results, apply light pressure on the sander, but do not force
the tool.
5. Move the sander slowly over the workpiece, making successive passes in
parallel lines, circles, or crosswise movements. The removal rate and the
sanding pattern are determined by the choice of sandpaper and the work
surface.
6. Do not allow the sander to stay on one spot for too long, as the sander’s rapid
action may remove too much material and make the surface uneven.
7. Upon completion of the sanding operation, remove the sander from the
workpiece, turn the sander off, and wait until it comes to a complete stop
before putting it down.
