Safety guidelines for power tools
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
4
headline bars
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.
continuation tabs
• Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep the
cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of
electric shock.
SAFETY GUIDELINES
7
model no. 054-7180-0 | contact us 1.800.689.9928
• 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.
notes
• 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.
• 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
Personal safety
• 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.
• Stay alert, watch what you are doing and use common sense when operating a power tool. Do
not use the tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention
while operating power tools may result in serious personal injury.
Special safety rules for sanders
• 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.
warnings
• Prevent unintentional starting. Ensure that the switch is in the off-position before connecting to a
power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on
the switch or plugging in 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.
• Hold power tools by the insulated gripping surfaces when performing an operation where the
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.
• A suitable breathing respirator must be worn while sanding lead paint, some woods and metal
to avoid breathing the harmful/toxic dust or air.
• Always wear safety goggles and a dust mask when sanding, especially when sanding overhead.
• The machine is not suitable for wet sanding.
• Do not overreach. Keep proper footing and balance at all times. This enables better control of the power
tool in unexpected situations.
• Do not use sanding paper that is larger than needed. Extra paper extending beyond the sanding pad
can also cause serious lacerations.
• 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.
• Secure the workpiece. A workpiece clamped with clamping devices or in a vice, is held more securely
than by hand.
• 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.
• Attach the dust bag to the tool and empty it frequently. Do not throw sanding dust on an open fire
because materials in fine particle form may be explosive.
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.

notes
3. Move the sander evenly over the entire work surface. The weight of the sander alone is sufficient for
normal use. Any excess pressure will alter the sanding action, providing an uneven finish, and will cause
extra wear to both the sander and sandpaper.
4. Never allow the sander to remain in one place on the work surface for too long or excessive material will
be removed.

5. The sander should never be turned off while resting on the workpiece. Lift the sander from the workpiece
and then turn it off.
6. Do not use the sander without sandpaper, or the pad will be damaged.
7. For optimum performance, make sure your hand does not cover the air ducts located on the sander, and
make sure that neither oil nor water comes in contact with the motor.

Sanding tips
1. Align the punch plate with the sanding pad and push down on the sander until the punch plate pierces the
sandpaper (see fig 2).
2. Remove the punch plate from the sanding
notespad.
1. Starting and stopping the sanding – Contact the workpiece with the tool only after it has reached full speed
and remove it from the work before turning the switch “OFF”. Operating in this manner will prolong switch
and motor life and will greatly increase the quality of your work.
2. Excessive pressure to the sander may result in an uneven sanding job and premature grit wear. Constant
and excessive pressure can cause overheating and possible damage to the motor, as well as premature
wear out of the pad.
a. Light pressure: recommended for fine work.
b. Moderate pressure: recommended for rough work.
c. Heavy pressure: does not allow the sand paper to rotate properly.
3. If the surface is rough, start sanding with a coarse grit, then medium, and then finish with a fine or extrafine grit. This procedure will vary with different types of material sand work.
warnings
4. Continue to sand with each grit until the surface looks uniform.
5. When going from one grit size to a finer size, do not skip more than two grit sizes.
6. To remove the greatest amount of stock, use a coarse grit and move the sander steadily over the entire
surface against the grain as well as with the grain. DO NOT REMAIN IN ONE SPOT TOO LONG. It may
remove too much material and uneven sanding will result.
7. Sanding with the grain of the wood gives the smoothest final finish.
WARNING!
• To reduce the risk of injury, turn the sander off and disconnect it from power source. An
accidental start-up can cause injury.
