ATTACHING ABRASIVE PAPER
Turn off and unplug the tool before making any adjustments or removing or
installing attachments or accessories. Be sure the switch is in the "OFF" position.
Your sander is designed to use 1/4 sized sanding sheets. You can size this paper by
a. cutting full sized (9" x 11") sandpaper into 1/4 sheets of 4-1/2" x 5-1/2".
b. cutting 1/2 sheet sandpaper into two 4-1/2" x 5 1/2" sheets. Pre-cut 4-1/2" x 5-1/2" sandpaper is
available at extra cost.
For normal operations, to attach the abrasive paper to your unit:
1. Soften the stiff sandpaper by pulling it over the 90° edge of a table or other straight edge (Fig. 1).
Concentrate on softening the edges that will be clamped.
2. Release the front and rear clamps by pulling up on the clamp levers (A) Fig. 2, and disengaging
them from the tabs on the base plate.
3. Insert one long edge of the abrasive paper (C) Fig. 4 under the front paper clamp until it contacts
the paper-limiting ribs. Close the front paper clamp (B) Fig. 3 and hook it into the lock position
behind the tab on the base plate.
4. Stretch the paper over the sanding pad and insert it under the opposite clamp in the same way.
5. If you are using the dust extraction feature, perforate the sandpaper with the provided paper punch
(Fig. 5).
SWITCH
To turn the unit on, depress the "ON" side of the dust protected switch Fig. 6. To turn the tool off,
depress the "OFF" side of the switch.
PAPER PUNCH
Turn off and unplug the tool before making any adjustments or removing or
installing attachments or accessories. Be sure the switch is in the "OFF" position.
A paper punch (Fig. 5) is provided with your sander to let you perforate regular sandpaper to make dust
collection possible.
To perforate your sandpaper, install the sandpaper on the tool as instructed in this manual. With the
sander turned off and unplugged, place the paper punch on the paper so that the tabs at the edges of
the punch are against any two adjacent sides (A) Fig. 5 of the sanding pad. Press the punch against
the pad so that the 8 points penetrate the paper. Press the punch into the pad as far as it will go.
Remove the paper punch. You can use an alternate method of perforating the paper by fastening the
punch to a suitable work surface with #8 flathead screws. Two holes are provided in the punch for this
purpose. Press the sander (with the paper attached) on the punch.
SAVE THESE INSTRUCTIONS!
Read all instructions. Failure to follow all instructions listed below may result in electric
shock, fi re and/or serious injury. The term “power tool” in all of the warnings listed below refers to your
mains-operated (corded) power tool or battery-operated (cordless) power tool.
To reduce the risk of injury, user must read instruction manual.
GENERAL SAFETY RULES
1) Work area safety
a)
Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) 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.
c) Keep children and bystanders away while operating a power tool. Distractions can
cause you to lose control.
2) Electrical safety
a) 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.
b) 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.
c) Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
d) 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. Use only 3-wire extension cords that
have 3-prong grounding-type plugs and 3-pole receptacles that accept the tool's plug.
e) 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. 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 following table shows the correct size to use depending on cord length
and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the
gauge number, the heavier the cord.

3) Personal safety
a) 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.
b) Use safety equipment. Always wear eye protection. Safety equipment such as
dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate
conditions will reduce personal injuries.
c) Avoid accidental starting. Ensure the switch is in the off-position before plugging in.
Carrying power tools with your finger on the switch or plugging in power tools that have the
switch on invites accidents.
d) 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.
e) Do not overreach. Keep proper footing and balance at all times. This enables better
control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewelry. Keep your hair, clothing and
gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in
moving parts.
g) If devices are provided for the connection of dust extraction and collection facilities,
ensure these are connected and properly used. Use of these devices can reduce dust-
related hazards.Accessories that may be suitable for one tool, may become hazardous
when used on another tool.
4) Power tool use and care
a) 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.
b) 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.
c) Disconnect the plug from the power source before making any adjustments,
changing accessories, or storing power tools. Such preventive safety measures reduce
the risk of starting the power tool accidentally.

d) 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.
e) Maintain power tools. Check for misalignment or binding of moving parts, breakage
of parts and any other condition that may affect the power tools operation. If
damaged, have the power tool repaired before use. Many accidents are caused by
poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc., in accordance with these
instructions and in the manner intended for the particular type of power tool, 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.
5) Service
a) 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.
ADDITIONAL SAFETY RULES FOR PAINT REMOVAL
Extreme care should be taken when removing paint. The peelings, residue, and
vapors of paint may contain lead, which is poisonous. Exposure to even low levels of lead can
cause irreversible brain and nervous system damage. Young and unborn children are particularly
vulnerable.
Before beginning any paint removal process you should determine whether the paint you are
removing contains lead. This can be done by your local health department or by a professional who
uses a paint analyzer to check for lead.
Lead-based paint should only be removed by a professional.
Persons removing paint should follow these guidelines:
1. Keep the work area well ventilated. Open the windows and put an exhaust fan in one of
them. Be sure the fan is moving air from inside to outside.
2. Remove or cover any carpets, rugs, furniture, clothing, cooking utensils, and air ducts.
Such preventive safety measures reduce the risk of exposure.
3. Place drop cloths in the work area to catch any paint chips or peelings. Wear protective
clothing such as extra work shirts, overalls and hats. Such preventive safety measures
reduce the risk of exposure.
4. Work in one room at a time. Furnishings should be removed or placed in the center of the
room and covered. Work areas should be sealed off from the rest of the dwelling by sealing
doorways with drop cloths.
5. Children, pregnant (or potentially pregnant) women and nursing mothers should not
be present in the work area until the work is done and all cleanup is complete. Such
preventive safety measures reduce the risk of injury.
6. Wear a dust respirator or a dual filter (dust and fume) respirator mask which has been
approved by the Occupational Safety and Health Administration (OSHA), the National
Institute of Safety and Health (NIOSH), or the United States Bureau of Mines. These
masks and replaceable filters are readily available at major hardware stores. Be sure the mask
fits. Beards and facial hair may keep the masks from sealing properly. Change filters often.
DISPOSABLE PAPER MASKS ARE NOT ADEQUATE.
7. Keep food and drink out of the work area. Wash hands, arms, and face and rinse mouth
before eating or drinking. Do not smoke or chew gum or tobacco in the work area.
8. Clean up all removed paint and dust by wet mopping the floors. Use a wet cloth to clean all
walls, sills and any other surfaces where paint or dust is clinging. DO NOT SWEEP, DRY DUST
OR VACUUM. Use a high phosphate detergent or trisodium (TSP) to wash and mop areas.
9. At the end of each work session, put the paint chips and debris in a double plastic bag,
close it with tape or twist ties and dispose properly. Such preventive safety measures
reduce the risk of exposure.
10. Remove protective clothing and work shoes in the work area to avoid carrying dust into
the rest of the dwelling. Wash work clothes separately. Wipe shoes off with a wet rag, then
wash that rag with the work clothes. Wash hair and body thoroughly with soap and water.
SAVE THESE INSTRUCTIONS!
MOTOR
Do not operate your tool on a current on which the voltage is not within correct limits.
Do not operate tools rated A.C. only on D.C. current. To do so may seriously damage the tool.
OPERATION
• ALWAYS WEAR EYE PROTECTION.
• It is not advised to sandpaper painted surfaces that may contain lead. See page 2 for
Precautions to Take When Sanding Paint.
• Clean your tool out periodically.
• Empty dust bag frequently. Especially when sanding resin coated surfaces such as
polyurethane, varnish, shellac, etc. The accumulation of fi ne sanding dust particles may self
ignite and cause fi re.
• Do not operate this tool for long periods of time. Vibration caused by the operating action
of this tool may cause permanent injury to fi ngers, hands, and arms. Use gloves to provide
extra cushion, take frequent rest periods, and limit daily time of use.
Some dust created by power sanding, sawing, grinding, drilling, and other con-
struction activities contains chemicals known to cause cancer, birth defects or other reproduc-
tive harm.
Some examples of these chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To reduce
your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, such as those dust masks that are specially designed to fi lter out microscopic particles.
Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and
other construction activities. Wear protective clothing and wash exposed areas with soap and water.
Allowing dust to get into your mouth, eyes, or lay on the skin may promote absorption of harmful
chemicals.
Use of this tool can generate and/or disburse dust, which may cause serious and per-
manent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection appro-
priate for the dust exposure. Direct particles away from face and body.
Wear appropriate hearing protection during use. Under some conditions and duration of
use, noise from this product may contribute to hearing loss.
ADDITIONAL SPECIFIC SAFETY RULES
Hold power tools by insulated gripping surfaces when performing an operation where the cutting 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.
