To obtain the best finish, start with a “COARSE” grade of abrasive and change to “MEDIUM” and “FINE” grades as work progresses.

A wide range of available PORTER-CABLE Sanding Belts are listed in the back of the manual. It is recommended that you keep a full assortment on hand so you will always have the correct belt for any job you may encounter.

GENERAL SANDING

1.CAUTION: SECURE WORK and maintain a FIRM GRIP on sander. Friction between sanding belt and work will try to move the work backwards and the sander forwards.

2.CAUTION: ALWAYS be sure switch is OFF before connecting sander to power circuit.

3.HOLD SANDER OFF the work and start motor.

4.LOWER SANDER TO WORK, letting the rear part of the belt touch first. Level the machine as it is moved forward.

5.GUIDE the machine over the work in overlapping strokes allowing the sander to do the work.

6.AVOID applying excessive pressure when sanding. The weight of the machine is usually sufficient for a fast smooth finish. A slight increase in pressure may speed removal of material, while too much pressure will slow the motor and decrease removal.

7.WORK BACK and FORTH over a fairly wide area to obtain an even surface.

8.DO NOT let the machine tilt or the edge of the belt will make a deep cut into the surface.

9.DO NOT PAUSE in any one spot during the sanding operation because the belt will quickly remove material making the surface uneven.

10.LIFT SANDER FROM WORK BEFORE TURNING OFF MOTOR.

11.ALWAYS be sure motor has completely stopped before setting sander down.

FAST SANDING ON ROUGH WORK

To smooth a rough surface quickly, use a coarse grit abrasive belt. With the belt positioned diagonally across the grain, move the sander in the direction of the grain as shown in Fig. 5. Overlap the strokes well and cover the entire surface, working from both sides of the board. That is, once with the sander angled to the left and once angled to the right. Smooth the surface by guiding the sander back and forth with the grain. Change the belt to a medium grit and follow the same procedure. Finish off by thoroughly working over the grain lengthwise. Change again to a fine grit and work entirely back and forth with the grain. Always finish your work by sanding with the grain.

REMOVING OLD PAINT AND VARNISH

CAUTION: Read and follow ADDITIONAL SAFETY RULES FOR PAINT REMOVAL section of this manual.

Your sander is an excellent tool for removing old paint and varnish from flat surfaces. Two problems are common to such work. One is loading the abrasive with the material being removed and the other is overheating the paint or varnish by working too long in one place. Use a coarse grit open coat abrasive belt and a single stroke action to overcome the loading
