starting operations.
To learn more about Porter-Cable
visit our website at:
The Model and Serial No. plate is located on the main
housing of the tool. Record these numbers in the
spaces below and retain for future reference.

2. Dress properly. Do not wear loose clothing or jewelry. Contain long
hair. Keep your hair, clothing, and gloves away from moving parts.
Loose clothes, jewelry, or long hair can be caught in moving parts.
3. Avoid accidental starting. Be sure switch is OFF before plugging in.
Carrying tools with your finger on the switch or plugging in tools that have
the switch ON invites accidents.
4. Remove adjusting keys or wrenches before turning the tool ON. A
wrench or a key that is left attached to a rotating part of the tool may result in
personal injury.
5. Do not overreach. Keep proper footing and balance at all times.
Proper footing and balance enable better control of the tool in unexpected
situations.
6. Use safety equipment. Always wear eye protection. Dust mask, non-
skid safety shoes, hard hat, or hearing protection must be used for
appropriate conditions.
TOOLS USE AND CARE
1. 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.
2. Do not force tool. Use the correct tool for your application. The
correct tool will do the job better and safer at the rate for which it is
designed.
3. Do not use tool if switch does not turn it ON or OFF. A tool that
cannot be controlled with the switch is dangerous and must be repaired.
4. Disconnect the plug from the power source before making any
adjustments, changing accessories, or storing the tool. Such preventive
safety measures reduce the risk of starting the tool accidentally.
5. Store idle tools out of reach of children and other untrained
persons. Tools are dangerous in the hands of untrained users.
6. Maintain tools with care. Keep cutting tools sharp and clean.
Properly maintained tools, with sharp cutting edges are less likely to bind
and are easier to control.
7. Check for misalignment or binding of moving parts, breakage of
parts, and any other condition that may affect the tool’s operation. If
damaged, have the tool serviced before using. Many accidents are
caused by poorly maintained tools.
8. Use only accessories that are recommended by the manufacturer
for your model. Accessories that may be suitable for one tool may become
hazardous when used on another tool.
SERVICE
1. Tool service must be performed only by qualified repair personnel.
Service or maintenance performed by unqualified personnel may result in a
risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow
instructions in the Maintenance Section of this manual. Use of
unauthorized parts or failure to follow Maintenance Instructions may create a
risk of electric shock or injury.
3
293741 - 09-30-01.qxd 2/13/02 9:31 AM Page 4
SPECIFIC SAFETY RULES AND SYMBOLS
1. Accessories must be rated for at least the speed recommended on
the tool warning label. Wheels and other accessories running over rated
speed can fly apart and cause injury.
2. 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 also make exposed metal parts of the
tool “live” and shock the operator.
3.
WARNING: There are certain applications for which this tool was
designed. Porter-Cable strongly recommends that this tool NOT be modified
and/or used for any application other than for which it was designed. If you
have any questions relative to its application DO NOT use the tool until you
have written Porter-Cable and we have advised you.

MOTOR
Many Porter-Cable tools will operate on either D.C., or single phase 25 to 60
cycle A.C. current and voltage within plus or minus 5 percent of that shown
on the specification plate on the tool. Several models, however, are designed
for A.C. current only. Refer to the specification plate on your tool for proper
voltage and current rating.
CAUTION: 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.
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.

may be installed on either side of the front housing to facilitate either right-
handed or left-handed operation. NOTE: This bailing handle SHOULD BE
USED AT ALL TIMES to maintain complete control of the machine.
Attach bailing handle (A) Fig. 2 with two M8 x 1 cap screws provided one of
which is shown at (B) Fig. 2. Tighten securely with 6mm allen wrench
provided.

VARIABLE SPEED
Speed is adjusted two ways:
1. With switch (A) Fig. 4, in the locked ON position use thumbwheel (C) Fig.
5, to adjust the speed (approximately 1000 RPM to 3000 RPM).
2. Switch (A) Fig. 4, can also be used to adjust the speed, 0 RPM to
approximately 3000 RPM, with maximum speed depending on the position
of thumbwheel (C) Fig. 5.
USING POLISHER
1. If item to be polished is light
enough to be moved by the
rotating polishing pad, it should
be securely anchored to prevent
possible bodily injury.
2. Hold polisher firmly by the
rear and auxiliary handles (see
Fig. 6), making sure polishing pad
is clear of work and foreign
objects. Start polisher and lower
at an angle so that approximately
Fig. 6
1/2 or slightly less of the polishing
pad contacts the work.
3. Move polisher in long continuous sweeping strokes. DO NOT HOLD
POLISHER IN ONE SPOT as this will create heat and possibly damage
surface being polished.
4. Lift polisher from work before turning off motor.
5. Always be sure motor has stopped before setting polisher down.
6. When using polisher to apply products (polishes, waxes, cleaners, etc).
always:
Read and follow directions supplied with product.
Start and stop polisher with pad against work surface, do not run
polisher while pad is not in contact with work surface.

293741 - 09-30-01.qxd 2/13/02 9:31 AM Page 8
POLISHING TIPS
USE ONLY QUALITY POLISH MADE FOR POWER POLISHING APPLICATION
and apply per manufacturer’s instructions.
For best results, thoroughly clean surface to be polished.
When polishing automobiles, wash the car thoroughly to remove dust, dirt
and other abrasives that may scratch the finish.
Buffs or pads may become gummed up after a period of use. They may be
washed out with soap and water. Shake out as much water as possible and
then spin dry on machine. Do this in an area where you will not splatter articles.
MAINTENANCE
KEEP TOOL CLEAN
Periodically blow out all air passages with dry compressed air. All plastic
parts should be cleaned with a soft damp cloth. NEVER use solvents to clean
plastic parts. They could possibly dissolve or otherwise damage the material.
CAUTION: Wear safety glasses while using compressed air.
FAILURE TO START
Should your tool fail to start, check to make sure the prongs on the cord plug
are making good contact in the outlet. Also, check for blown fuses or open
circuit breakers in the line.
LUBRICATION
This tool has been lubricated with a sufficient amount of high grade lubricant
for the life of the unit under normal operating conditions. No further
lubrication is necessary.
BRUSH INSPECTION AND LUBRICATION
For your continued safety and electrical protection, brush inspection and
replacement on this tool should ONLY be performed by an AUTHORIZED
PORTER-CABLE SERVICE STATION or a PORTER-CABLE/DELTA SERVICE
CENTER.
At approximately 100 hours of use, take or send your tool to your nearest
Authorized Porter-Cable Service Station to be thoroughly cleaned and
inspected; worn parts replaced, when necessary; relubricated with fresh
lubricant, if required; reassembled with new brushes; and performance tested.
Any loss of power before the above maintenance check may indicate the
need for immediate servicing of your tool. DO NOT CONTINUE TO OPERATE
TOOL UNDER THIS CONDITION. If proper operating voltage is present,
return your tool to the service station for immediate service.
