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.

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.

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.

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.

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

An auxiliary handle (A) Fig. 1 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

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) Fig. 1 forward to start the motor. Slide the switch button to the rear to stop the motor.

VARIABLE SPEED

Adjust the speed by turning the thumbwheel (C) Fig. 2. Thumb-wheel position #1 provides the slow- est 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)

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.

1.Place the tool on the work-bench with the pad up (Fig. 4).

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

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.

1.Engage the flats of the spindle (D) Fig. 5 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 Fig. 5 for clarity.

C.A spacer is supplied with the 7346SP and 7424XP to allow the backup pad to clear the eccen- tric plate screws (F) Fig. 5. 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 counterclock- wise 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 work- piece 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

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.

1.Remove sander pad (G) Fig. 4.

2.Loosen Phillips head screw (H) Fig. 7 on dust collection adapter (I) and slide the adapter up onto the vacuum housing (J) as shown in Fig. 7.

3.Orient dust hole (K) Fig. 8 as shown and tighten Phillips head screw.

4.Attach dust hose adapter (L) and dust hose (M) as shown.

CLEANING

Periodically blowing dust and chips out of the motor housing using clean, dry compressed air is a suggested maintenance procedure. To reduce the risk of serious personal injury, ALWAYS wear ANSI Z87.1 safety glasses while using compressed air.

When cleaning, use only mild soap and a damp cloth on plastic parts. Many household cleaners contain chemicals which could seriously damage plastic. Also, do not use gasoline, turpentine, lacquer, paint thinner, dry cleaning fluids or similar products which may seriously damage plastic parts. Never let any liquid get inside the tool; never immerse any part of the tool into a liquid.

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.
