1.  Remove the three gear case cover screws (B) Fig. 5 counter-clockwise with a 9/64" hex 

wrench.

NOTE: Retain the screws in case you want to use the power unit without the paint remover 
attachment. (Using the the longer screws without the paint remover attachment will damage the 
internal gears).
2.  Attach the paint remover attachment on the power unit (Fig. 6). Secure it with three round head 

machine screws (supplied). Tighten the screws firmly.

3.  Thread the aluminum and sponge rubber back-up pad (A) Fig. 7 on the machine spindle. Hand 

tighten.

4.  Select the Porter-Cable tungsten carbide disc with grit size best suited for the job. Center the 

disc on the back-up pad (Fig. 8) and thread the disc retaining nut on the spindle. Depress the 
spindle lock pin (A) Fig. 8 and rotate pad by hand until the lock engages and stops the pad 
rotation. Hold the spindle lock pin down while using the spanner wrench (B) Fig. 8 to firmly 
tighten the disc retaining nut.

The Model 7403 is designed for use with specific discs and pads. The use of any other back-up 
pads or discs could be hazardous.
HOW TO HOLD THE TOOL
Hold the tool firmly with both hands (Fig. 9).

TO START AND STOP THE TOOL
To start the tool, depress the trigger (A) Fig. 10. To stop the tool, release the trigger. This tool has a 
lock button (B) Fig. 10, conveniently located in the tool handle. To keep tool running continuously, 
depress the trigger (A) and push in the switch locking button (B) on the left side of the handle. While 
holding the button in, release the trigger. To release the locking button, depress the trigger and 
release.

 Make certain that the switch is in the “OFF” position before connecting the tool to the 

power source to avoid unintentional starting.
VARIABLE SPEED 
You can adjust the speed of this tool by turning the thumbwheel (C) Fig. 10. Thumbwheel position 
#1 provides the slowest operating speed (3300 RPM) and position #6 the fastest (4500 RPM). You 
can change the speed while the  motor is running or not running.
ADJUSTING GUIDE SCREWS 

before installing and removing accessories, before adjusting or when making repairs. An 
accidental start-up can cause injury. 
For most applications, position the buttonhead guide screws (A) Fig. 11 so that a straight-edge (B) 
placed on them will just barely clear the pad edge (C). In this position, the pad rim will not rub the 
clapboard edge on which the screws ride. You can adjust the screws to keep the pad edge farther 
away from the overlapping clapboard. To change the positions of the screws, loosen the lock nuts, 
adjust the screws and tighten lock nuts. Make sure the screws do not turn or change position while 
tightening lock nuts.
ADJUSTING SIDE RAILS 

before installing and removing accessories, before adjusting or when making repairs. An 
accidental start-up can cause injury. 
Two knobs (A) Fig. 12 are provided for controlling the movement of the side rails, above or below 
the pad. For manual instruction purposes, the right knob is on the same side of the motor frame 
as the sander handle. The right side rail is controlled by this knob. To lower the right side rail, turn 
the right control knob toward the front of the machine. To raise the right side rail, turn the right 
control knob toward the rear of the machine. To lower the left side rail, turn the left control knob 
toward the rear of the machine. To raise the left side rail, turn the left control knob toward the 
front of the machine.
The distance of the rails above and below the pad edge determines the depth of cut. For most 
applications, satisfactory operation will result when one side rail is adjusted so it is 1/32" above 
the pad edge, and the other rail 1/32" below the pad edge (see Fig. 12). For removing very thin 
coats of paint, make the depth of cut smaller by moving the rail above the pad downward. Use a 
piece of scrap lumber to try several positions until you find the height best suited for the job. Do 
not change the position of the rail that is 1/32" below the pad edge.
SPOT SANDING
To sand small areas, start the motor and place the button-head guide screws against the edge of 
the clapboard above the sanding area. Lower the abrasive disc on the clapboard and move the 
machine back and forth from left to right until the paint has been removed (Fig. 13). To sand close to 
the edge of the board above, tilt the tool forward.
To sand the lower part of wide clapboards, move the tool down and up, back and forth from left to 
right, and in circles. To spot sand from a ladder, firmly anchor the ladder close enough to the work 
area to prevent excessive reach. Work with one arm outside one of the legs of the ladder and the 
other between the rungs of the ladder (Fig. 14).
SANDING LARGE AREAS
Use a scaffold to sand large areas that cannot be reached from the ground. Sand in the same 
manner that you would sand small areas - left to right, right to left, up, down, or in a circular path 
until you have covered the entire surface.
SANDING UP TO WINDOW OR DOOR FRAMES
If the window or door frame is on your left, adjust the left rail of the paint remover so that it is higher 
than the edge of the pad. Adjust the right rail so that it is lower than the edge of the pad. If the 
window or door frame is to your right, adjust the rails in the opposite way.
REMOVING PAINT FROM PORCHES
To remove paint from porches, raise one rail above the pad edge and lower the other rail below the 
pad edge. The machine can be moved from left to right, right to left, or in circular paths (Fig.15).
FLOOR EDGING
Adjust the paint remover guide screws so that paint can be removed up to the intersection of two 
surfaces. This, coupled with the light weight and ease of handling, makes the Disc Sander–Paint 
Remover ideal for secondary floor edging jobs.
SANDING MASONRY
The Paint Remover is excellent for preparing masonry surfaces for painting. Use a #24 or #36 grit 
carbide disc for this job since the grit on paper discs is quickly destroyed. Masonry is sanded in the 
same manner as wood.
