ALWAYS
use safety glasses. Everyday eyeglasses are NOT safety glasses. Also use
face or dust mask if cutting operation is dusty. ALWAYS WEAR CERTIFIED SAFETY EQUIPMENT:
• ANSI Z87.1 eye protection (CAN/CSA Z94.3),
• ANSI S12.6 (S3.19) hearing protection,
• NIOSH/OSHA/MSHA respiratory protection.
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, and
• 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, such as those dust masks that are specially designed to filter 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 disperse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.
Always wear proper personal hearing protection that conforms to ANSI S12.6
(S3.19) during use.
Under some conditions and duration of use, noise from this product may
contribute to hearing loss.

ADDITIONAL SAFETY RULES FOR PAINT REMOVAL
1. Sanding of lead based paint is NOT RECOMMENDED due to the difficulty of controlling the
contaminated dust. The greatest danger of lead poisoning is to children and pregnant women.
2. Since it is difficult to identify whether or not a paint contains lead without a chemical analysis,
we recommend the following precautions when sanding any paint:
PERSONAL SAFETY
1. No children or pregnant women should enter the work area where the paint sanding is being
done until all clean up is completed.
2. A dust mask or respirator should be worn by all persons entering the work area. The filter
should be replaced daily or whenever the wearer has difficulty breathing. See your local
hardware store for the proper NIOSH approved dust mask.
3. NO EATING, DRINKING or SMOKING should be done in the work area to prevent ingesting
contaminated paint particles. Workers should wash and clean up BEFORE eating, drinking
or smoking. Articles of food, drink, or smoking should not be left in the work area where dust
would settle on them.
ENVIRONMENTAL SAFETY
1. Paint should be removed in such a manner as to minimize the amount of dust generated.
2. Areas where paint removal is occurring should be sealed with plastic sheeting of 4 mil thickness.
3. Sanding should be done in a manner to reduce tracking of paint dust outside the work area.
CLEANING AND DISPOSAL
1. All surfaces in the work area should be vacuumed and thoroughly cleaned daily for the
duration of the sanding project. Vacuum filter bags should be changed frequently.
2. Plastic drop cloths should be gathered up and disposed of along with any dust chips or other
removal debris. They should be placed in sealed refuse receptacles and disposed of through
regular trash pick-up procedures. During clean up, children and pregnant women should be
kept away from the immediate work area.
3. All toys, washable furniture and utensils used by children should be washed thoroughly before
being used again.
Accessories must be rated for at least the speed recommended on the tool warning label.
Accessories running over rated speed can fly apart and cause injury. Accessory ratings must always be
above tool speed as shown on tool nameplate.
SAVE THESE INSTRUCTIONS FOR FUTURE USE
MOTOR
Be sure your power supply agrees with nameplate marking. 120 Volts AC means your tool will operate on
alternating current. As little as 10% lower voltage can cause loss of power and can result in overheating.
All PORTER-CABLE tools are factory-tested; if this tool does not operate, check the power supply.

OPERATION
To reduce the risk of injury, turn unit off and disconnect it from power source
before installing and removing accessories, before adjusting or when making repairs.
An
accidental start-up can cause injury.
AUXILIARY HANDLE (FIG. 1)
An auxiliary handle (A) is furnished with the tool. You can install the auxiliary handle on either side
of the front housing to facilitate either right-handed or left-handed operation.
Use this handle at all times to maintain complete control of the tool.
TO START AND STOP TOOL (FIG. 1)
Make certain that the switch is in the “OFF” position, and the power source is the same as that
specified on the tool’s nameplate.
1. Connect the tool to the power source.
2. Slide the switch button (B) forward to start the motor. Slide the switch button to the rear to
stop the motor.
VARIABLE SPEED (FIG. 2)
Adjust the speed by turning the thumbwheel (C). Thumb-wheel position #1 provides the slowest
operating speed (2500 OPM) and position #6, the fastest (6800 OPM). You can change the speed
while the motor is running or while it is stopped.
USING THE POLISHER (FIG. 3)
If your workpiece is so light that it can be moved by the rotating pad, anchor it
securely to prevent possible bodily injury.
1. Read and follow the directions supplied with the product (polishes, waxes, cleaners, etc.).
2. Apply a small amount of the product directly to the polishing pad.
3. Grasp the polisher firmly with both hands - one hand on auxiliary handle and one hand on
motor housing.
4. Position the polisher with the polishing pad against the work surface and start the polisher.
NEVER run or stop the tool when it is not in contact with the work surface.
5. Move the polisher back and forth in a sweeping motion, over-lapping each previous pass.
6. DO NOT apply additional pressure. Allow the polisher to work under its own weight.
7. Do not mix products (wax, polish, cleaner, etc.) on the same pad. Label each pad to prevent
confusion.
8. The polishing pad is designed for product application only. Remove product residue with a soft
cotton cloth.
INSTALLING/REMOVING ABRASIVE DISC (FIG. 4)
1. Place the tool on the work-bench with the pad (G) up.
2. Clean dust from the pad face.
3. Position the disc on the sander pad and press the disc firmly on the pad.
4. Position the tool with the abrasive contacting scrap material. Start the tool and operate it
momentarily with firm pressure to seat the disc to the pad.
Failure to properly seat the disc to the pad may result in the disc being thrown from
the pad, causing personal injury.
6. Remove the disc by peeling it away from pad.
NOTE FOR PSA PADS:
Do not store the tool with the abrasive disc installed. Heat generated by
the sanding operation increases the adhesive bond between the disc and the pad. If the disc is left
on the pad for an extended period of time after use, it will be difficult to remove.
CHANGING THE BACK-UP PAD (FIG. 5)
1. Engage the flats of the spindle (D) with the supplied spindle wrench (E).
NOTES:
A. If necessary, rotate the pad by hand to expose the spindle flats.
B. The pad is removed in Figure 5 for clarity.
C.
A spacer is supplied with the 7346SP and 7424XP to allow the backup pad to clear the
eccentric plate screws (F). Mount the spacer on the shaft before attaching the backup pad.
2. While holding the spindle with the wrench, use your other hand to rotate the pad counter-
clockwise to remove.
3. To install the pad, reverse the above procedure.
USING THE SANDER (FIG. 6)
Secure the workpiece to prevent it from moving. Friction between the sanding disc and the
workpiece can spin the workpiece away from sander and may cause bodily injury.
Always use eye protection. To reduce the risk of injury, all users and bystanders must
wear eye protection that conforms to ANSI Z87.1.
Use of this tool can generate and/or disburse dust, which may cause serious and
permanent respiratory or other injury. Always use NIOSH/OSHA approved respiratory protection
appropriate for the dust exposure. Direct particles away from face and body.
INSTALLING ACCESSORY DUST COLLECTION ADAPTER AND HOSE (FIG. 4, 7, 8)
1. Remove sander pad (G).
2. Loosen Phillips head screw (H) on dust collection adapter (I) and slide the adapter up onto the
vacuum housing (J) as shown in Figure 7.
3. Orient dust hole (K) as shown and tighten Phillips head screw.
4. Attach dust hose adapter (L) and dust hose (M) as shown.
