Some dust created by power sanding, sawing, grinding,
drilling, and other construction activities contains chemicals
known (to the State of California) 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
• arsenic and chromium from chemically-treated lumber
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, always wear
NIOSH/OSHA approved, properly fitting face mask or respirator when using
such tools.

Read all instructions. Failure to follow all
instructions listed below may result in electric
shock, fire 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
SAVE THESE INSTRUCTIONS
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.
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.
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.

5
GENERAL SAFETY RULES continued
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.
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.

6
1. 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.
2. Sanding of lead-based paint is not recommended. Lead-based paint
should only be removed by a professional.
3. Always maintain a firm grip on the sander handles with both hands to
prevent loss of control.
4. Do not operate sander without all guards and covers securely in place.
5. Wear eye and hearing protection. Always use safety glasses. Everyday
eyeglasses are NOT safety glasses. USE CERTIFIED SAFETY EQUIPMENT.
Eye protection equipment should comply with ANSI Z87.1 standards.
Hearing equipment should comply with ANSI S3.19 standards.
6. Use of this tool can generate and disburse dust or other
airborne particles, including wood dust, crystalline silica
dust and asbestos dust. Direct particles away from face and body.
Always operate tool in well ventilated area and provide for proper dust
removal. Use dust collection system wherever possible. Exposure to the
dust may cause serious and permanent respiratory or other injury, including
silicosis (a serious lung disease), cancer, and death. Avoid breathing the
dust, and avoid prolonged contact with dust. Allowing dust to get into
your mouth or eyes, or lay on your skin may promote absorption of harmful
material. Always use properly fitting NIOSH/OSHA approved respiratory
protection appropriate for the dust exposure, and wash exposed areas with
soap and water.

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.

EXTENSION CORD SELECTION
If an extension cord is used, make sure the conductor size is large enough to
prevent excessive voltage drop which will cause loss of power and possible
motor damage. A table of recommended extension cord sizes will be found in
this section. This table is based on limiting line voltage drop to 5 volts (10 volts
for 230 volts) at 150% of rated amperes.
If an extension cord is to be used outdoors, it must be marked with the suffix W-
A or W following the cord type designation. For example – SJTW-A to indicate it
is acceptable for outdoor use.

Abrasives are available in precut sheets or in rolls that can be cut-to-fit
the various profiles.
E. Offset “Shutter” Pad: This pad permits access to recessed surfaces,
such as those found on louvered shutters. (Fig. 6) Special PSA Abrasives
are available in rolls that can be cut-to-fit this pad.

12
SELECTING THE ABRASIVE
The best finishes can be achieved by selecting the proper type of abrasive.
coarser grit abrasives will remove the most material while finer grit abrasives
will produce the best finishes.
Achieve best results by selecting the proper size and type of abrasives. Start
the work with an abrasive grit just coarse enough to remove high spots and
excessive roughness. Follow with a second sanding using a grit one or two
grades finer. Continue using successively finer grits until the desired finish is
obtained.
ATTACHING PAD OR PROFILE MOUNTING PLATE
All of the accessory pads and profile mounting plates are attached to the tool
in the same way. Each pad or mounting plate has two posts (A) Fig. 7 used to
attach it to the Profile Sander.
One pad post fits into a pocket (B) Fig. 7 in the tool, and the other post is
locked into place by a tab (C) Fig. 7. The mounting post area (of all the pads
and mounting plates) is symmetrical. The pad (or mounting plate) can be
attached to the Profile Sander with either end forward, which allows the use
of both pointed ends of each sheet of pad abrasive, and permits the profile
holders to be mounted in the best position for each particular application.
To attach a pad or mounting plate to the Profile Sander:
1. Position one of the pad (or mounting plate) posts (A) Fig. 7 into the
pocket (B) Fig. 7 of the Profile Sander (Fig. 8).
2. Depress latch button (D) Fig. 9, seat pad to sander, and release latch
button to secure the pad in place (Fig. 10).
3. To remove pad (or mounting plate), depress latch button (D) Fig. 9, and
pull pad away from sander.

ATTACHING PROFILE TO MOUNTING PLATE
Individual profiles may be mounted to either the Single Profile Mounting Plate,
or the Angled Profile Mounting Plate (Figs. 11 and 12). The individual profiles
are pressed into the slot on the mounting plate by hand, and can be removed
from the mounting plate by pulling outward on one end of the profile.
ATTACHING ABRASIVES
Three different types of abrasives that can be used with the Profile Sander
are:
HOOK & LOOP SHEETS: These are precut sheets with hook & loop backing
and dust extraction holes. This abrasive is used with the diamond shaped
Hook & Loop Pad. Align the abrasive with the sander pad and press into place
with the palm of your hand. Use a light twisting motion to lock the hooks into
the loops. To remove abrasive, lift one corner with your fingernail and peel it
off. These abrasives may be removed and reattached several times.
PSA SHEETS: These are precut sheets with pressure sensitive adhesive.
Precut diamond shaped sheets are available to fit the optional diamond
shaped PSA Pad. Precut rectangular sheets are available to fit all of the
individual profiles. Peel the protective sheet from the back of the abrasive.
Align the abrasive with the sander pad and press firmly into place. To remove
abrasive, lift one corner with your fingernail and peel it off. Discard the used
abrasive.
PSA ROLLS: These are 21/2" wide rolls with pressure sensitive adhesive. This
abrasive is used with the individual profiles and with the extended “shutter”
pad. Unroll a strip of abrasive to fit the particular profile (or pad), and cut to
length with scissors. NOTE: For best results, the abrasive should cover all
of the exposed profile below the profile holder. Firmly press the abrasive in
place on the profile (or pad). To remove abrasive, lift one corner with your
fingernail and peel it off. Discard the used abrasive.
NOTE: PSA Pads and Profiles must be clean for the abrasives to adhere
properly. Clean the pads and profiles with soap and water.
PSA Adhesives work best at temperatures above 25° F. If PSA abrasives,
pads, or profiles are stored at lower temperatures, warm them before use.
Store PSA Pads in a dust-free environment to prevent contamination of the
adhesive.

ATTACHING OPTIONAL DUST WAND
NOTE: A wide variety of accessories, including a dust wand, is available for
this tool. Please refer to your Porter-Cable Catalog to determine if the dust
wand is supplied as standard equipment with your particular tool package.
The dust wand is available as an accessory, and may be used with any
Porter-Cable Model 444 Profile Sander.
The dust wand requires an external vacuum source (shop vac or dust
collection system). To attach dust wand to sander:
1. Insert dust wand pin (A) Fig. 13 into hole (B) Fig. 13.
2. Thread knob (C) Fig. 14 into tool, and tighten firmly.
3. Connect the dust wand to your vacuum source with a 1" vacuum hose.
TO START AND STOP SANDER

SPEED CONTROL (444VS only)
Model 444VS is equipped with a variable speed control. Operating speed is
adjustable between 2100 SPM (Strokes Per Minute) and 6000 SPM.
Speed is adjustable by turning thumbwheel (B) Fig. 15A. Thumbwheel
position #1 provides the slowest operating speed (2100 SPM) and position
#6 the fastest (6000 SPM). Speed may be changed while motor is running or
while stopped.
USING THE SANDER
The Porter-Cable Profile Sander has been designed for one-hand operation
(Fig. 16). The sander can be easily guided over the work surface with one
hand. The normal weight of the machine is sufficient for efficient sanding.
Additional pressure on the tool will slow down the speed of the pad, reduce
the sanding efficiency, and put an additional burden on the motor.
The Profile Sander uses an “in-line” sanding motion. To achieve the best
surface finish, sand “in-line” with the wood grain. Faster removal rates can
be achieved by operating the sander across the grain while working out
rough areas, and then finishing by sanding with the grain.
FINE FINISHING
The action of the tool causes thousands of tiny abrasive grits to move
against the work at high speed. Each grain moves in the same direction
and at a constant speed, causing the cutting action to be uniform over the
entire pad surface. Start the work with an abrasive grit just coarse enough to
remove the high spots and excessive roughness.
Follow with a second sanding using a grit one or two grades finer. Continue
with successively finer grits until the desired finish is obtained. DO NOT GO
FROM A COARSE GRIT TO A VERY FINE GRIT IN ONE STEP.
REMOVING PAINT AND VARNISH
Read and follow all instructions in the “ADDITIONAL
SAFETY RULES FOR PAINT REMOVAL” section of this manual.
Fig. 16

16
To remove old paint and varnish:
1. Use a coarse, open coat abrasive to avoid the usual clogging of the
abrasive surfaces.
2. Keep the machine moving over new areas to avoid heating and softening
the material being removed.
Try to work the entire surface at the same time by working in wide, over-
lapping arcs. Do not concentrate on small areas. When using liquid removers
or heaters to speed the work, scrape away all excess paint or varnish with
a putty knife or other suitable scraping tool, and allow the wood to be cool
and dry before sanding.
DOORS AND MOLDINGS
The “in-line” motion of the Profile Sander is ideally suited for use in the
recessed corners and on the intricate profiles found on moldings and raised-
panel doors. The diamond shaped pads make sanding the recessed corners
easy, while the wide variety of available sanding profiles allow you to exactly
match each detail of intricate molding configurations.

LA PROPOSICION DE CALIFORNIA 65
Algunos tipos de aserrín creados por máquinas eléctricas de lijado,
aserrado, amolado, perforado u otras actividades de la construcción, contienen materiales
químicos conocidos (en el Estado de California) como causantes de cáncer, defectos de
nacimiento u otros daños del aparato reproductivo. Algunos ejemplos de dichos productos
químicos son:
• El plomo contenido en algunas pinturas con base de plomo
• Sílice cristalizado proveniente de los ladrillos, el cemento y otros productos de
albañilería
• Arsénico y cromo de madera tratada químicamente
Su riesgo por causa de estas exposiciones varía, dependiendo de con cuánta frecuencia
realice este tipo de trabajo. Para reducir su exposición a estos agentes químicos: trabaje en
un área bien ventilada y trabaje con equipo de seguridad aprobado, use siempre protección
facial o respirador NIOSH/OSHA aprobados cuando deba utilizar dichas herramientas.
Lea y entienda todas advertencias y las instrucciones operadoras
antes de utilizar cualquier instrumento o el equipo. Cuando se usa instrumentos o equipo,
