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 fl am-
mable 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) Grounded tools must be plugged into an outlet properly installed and grounded in accor-
dance with all codes and ordinances. Never remove the grounding prong or modify the plug in
any way. Do not use any adaptor plugs. Check with a qualifi ed electrician if you are in doubt
as to whether the outlet is properly grounded. If the tools should electrically malfunction or
break down, grounding provides a low resistance path to carry electricity away from the user.
Applicable only to Class I (grounded) tools.
b) Double insulated tools are equipped with a polarized plug (one blade is wider than the
other.) This plug will fi t in a polarized outlet only one way. If the plug does not fi t fully in the
outlet, reverse the plug. If it still does not fi t, contact a qualifi ed electrician to install a polarized
outlet. Do not change the plug in any way. Double insulation eliminates the need for the three
wire grounded power cord and grounded power supply system. Applicable only to Class II
(double insulated) tools.
c) 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.
d) Do not expose power tools to rain or wet conditions. Water entering a power tool will in-
crease the risk of electric shock.
e) 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 ground-
ing-type plugs and 3-pole receptacles that accept the tool's plug.
f) When operating a power tool outdoors, use an extension cord suitable for outdoor use. If
an extension cord is to be used outdoors, it must be marked with the suffi x W-A or W following
the cord type designation. 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.
Minimum Gauge for Cord Sets

120V 0-25
240V 0-50 51-100
Ampere Rating Gauge of wire in AWG units
From 0 to 6 amps 18
" 6 to 10 amps 18
" 10 to 12 amps 16
" 12 to 16 amps 14
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 infl uence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in serious personal injury.
b) 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.
c) Avoid accidental starting. Be sure the switch is in the off-position before plugging in. Carrying
power tools with your fi nger 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) 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.
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 haz-
ards. Accessories that may be suitable for one tool, may become hazardous when used on
another tool.
4) Power tool use and care
a) Use clamps or other practical way to secure and support the workpiece to a stable platform.
Holding the work by hand or against your body is unstable and may lead to loss of control.
b) 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.
c) 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.
d) Eject 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.

e) 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 dan-
gerous in the hands of untrained users.
f) Maintain power tools. Check for misalignment or binding of moving parts, break-
age 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.
g) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting
edges are less likely to bind and are easier to control.
h) Use the power tool, accessories and tool bits etc., in accordance with these instruc-
tions and in the manner intended for the particular type of power tool, taking into ac-
count 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 qualifi ed repair person using only identical re-
placement parts. This will ensure that the safety of the power tool is maintained.
ADDITIONAL SPECIFIC SAFETY RULES
Some dust created by power sanding, sawing, grinding, drilling, and other
construction activities contains chemicals known to cause cancer, birth defects or other
reproductive 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.
• Accessories must be rated for at least the speed recom mended on the tool warning label.
Wheels and other accessories running over rated speed can fly apart and cause injury. Accessory
ratings must be above listed minimum wheel speed as shown on tool nameplate.
• Hold tool 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.
• Always wear eye protection and a respirator when sanding.
• Sanding of lead-based paint is not recommended. See "PRECAUTIONS TO TAKE WHEN
SANDING PAINT" for additional information before sanding paint.
• Do not operate the unit without the dust container.
• Clean your tool out periodically.
• Empty the dust container frequently, especially when sanding resin coated surfaces such
as polyurethane, varnish, shellac, etc. Dispose of coated dust particles according to the finish
manufacturer's guidelines, or place in a metal can with a tight-fitting metal lid. Remove coated dust
particles from the premises daily. The accumulation of fine sanding dust particles may self ignite
and cause fire.

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.
ATTACHING ABRASIVE PAPER
Your sander is designed to use 5" (127 mm) sanding discs with an 8-hole dust extraction pattern.
Sanding discs for the model 343 and 343VS attach with hook and loop. Sanding discs for the model
344 attach with pressure sensitive adhesive (PSA).
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.
1. Turn the sander over so that the sanding pad is facing upward (Fig. 1).
2. Clean the dust from the vinyl pad face.
3. Hold the pad with one hand to keep it from rotating (Fig. 2).
4. With the other hand, align the holes and place the disc directly on top of the pad (Fig. 3).
NOTE: Do not use the sanding screen (the screen used for sanding drywall) directly on the hook and
loop pad. The screen will not hold and will damage the hooks on the pad. The hooks will wear very
rapidly if left in contact with the work surface while the tool is operating.
SWITCH
To turn the unit on, depress the "ON" side of the dust protected switch (B) Fig. 4). To turn the tool
off, depress the "OFF" side of the switch.
SPEED CONTROL DIAL (343VS only)
The speed control dial (A) Fig. 5 allows you to increase or decrease the speed from 7,000-12,000
orbits per minute. The optimal speed setting for each application is very much dependent on
personal preference. Generally, you will want to use a higher setting on harder materials and a lower
setting on softer materials. Material removal rate increases as speed increases.
PAD BRAKE
These sanders are equipped with a pad brake that prevents over-speeding of the pad. If the tool
is lifted off the work surface while the motor is running, the brake will limit pad rotation to no more
than 400 RPM.
The pad brake uses a belt to provide the braking action. Eventually, this belt may require replace-
ment. If the brake fails to limit pad rotation, send the sander to a Porter-Cable service facility or
replace the belt yourself using the information in "BELT REPLACEMENT" in the maintenence
section of this manual.
