7. To remove disc, peel disc away from pad. NOTE: Do not store machine with an abrasive disc installed. Heat generated by the sanding operation increases the adhesive bond between the disc and pad. If disc is left on pad for an extended time after use, it can become difficult to remove. 10 Fig. 2 Fig. 3 Models 333 and 333VS: 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Place machine on workbench with pad up (see Fig. 3). 3. Clean dust from pad face. 4. Position Hook & Loop Abrasive Disc onto sander pad, aligning the dust extraction holes in paper with holes in pad. NOTE: When using 8-hole abrasive on model 333VS, align the hole pattern in the abrasive with the groove in the sander pad. Do not use PSA (Pressure Sensitive Adhesive) disc with Hook & Loop pad as the disc may be thrown from the pad causing personal injury. 5. Press disc firmly onto pad. Failure to properly seat disc to pad may result in disc being thrown from pad causing personal injury. 6. To remove disc, peel disc away from pad. DUST COLLECTOR (Models 333, 333VS and 334) 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Position dust collector to sander nozzle as shown in Fig. 4. Seat collector onto nozzle. 3. Periodically remove dust container from flange and empty collected dust, Fig. 5. NOTE: A slight twisting action will ease removal and reassembly. Tap container lightly to remove compacted dust. DO NOT WASH CONTAINER. Dry compressed air may be used to blow out container. DUST COLLECTOR NOZZLE Fig. 4 11 Wear safety glasses while using compressed air. Never run sander with dust container or dust collector assembly removed. Dust could be blown into eyes. The dust collector may be replaced with Accessory Hose so that tool can be used with a remote vacuum system. FLANGE DUST CONTAINER Fig. 5 OPERATION TO START AND STOP SANDER 1. Make certain the switch is in the “OFF” position, and the power source is the same as that specified on the tool’s nameplate. 2. Connect the tool to the power source. Keep hands and body parts away from rotating disc. Contact with rotating disc can cause severe cuts and abrasions. 3. The switch button, (A) Fig. 1, is labeled “ON” and “OFF”. Depress the “ON” end of the switch button to start motor. Depress the “OFF” end of the switch button to stop motor. SPEED CONTROL (333VS) Model 333VS is equipped with a variable speed control. Operating speed is adjustable between 5000 OPM (Orbits Per Minute) and 12000 OPM. Adjust speed by turning thumbwheel (B) Fig. 1A. Thumbwheel position #1 provides the slowest operating speed (5000 OPM) and position #6 the fastest (12000 OPM). Speed may be changed while motor is running or while it is stopped. HOW TO HOLD SANDER These sanders are designed to be held either around the main housings, Fig. 7, or by the top of the main housings, Fig. 8. When sanding for long periods, it is recommended you periodically alternate between the two holding positions. Fig. 7 Fig. 8 12 PAD BRAKE These sanders are equipped with a pad brake that prevents over-speeding of the pad. If the tool is lifted off the work surface while the motor is running, the brake will limit pad rotation to no more than 400 RPM. The pad brake uses a belt to provide the braking action. Eventually, this belt may require replacement. If the brake fails to limit pad rotation, send the sander to a Porter-Cable service facility or replace the belt yourself as explained under BELT REPLACEMENT in the MAINTENANCE SECTION of this manual. USING THE SANDER 1. Secure work to prevent it from moving during the sanding operation. Friction between the sanding disc and work will try to spin work away from sander and may cause bodily injury. 2. WEAR SAFETY GLASSES AND DUST MASK. 3. Place sander pad in light contact with the work before switching the motor “ON”. 4. Grasp sander firmly and move switch to “ON” position. 5. Move sander in long overlapping strokes. Tipping sander or stopping in one spot can produce an uneven finish. 6. When finished, keep pad in contact with work, move switch to “OFF” position and lift sander from the work. Allow pad rotation to stop completely before setting sander down.

DISCONNECT TOOL FROM POWER SOURCE. 2. Grasp pad with hand and use phillips screwdriver to remove three pad retaining screws, Fig. 9 (turn screws counterclockwise to remove). 3. Lift pad from sander. 4. Reverse procedure to install new pad. Tighten pad retaining screws 25 to 30 in-lbs. PAD RETAINING SCREWS Fig. 9 13 BELT REPLACEMENT 1. DISCONNECT TOOL FROM POWER SOURCE. 2. Remove back-up pad (see CHANGING BACK-UP PAD). 3. Remove the old belt and clean the belt mounting area. 4. Position the new belt around pulley (A) Fig. 10, and start it onto the shoulder of the pad support (B). 5. Rotate the pad support as you “walk” the belt onto it (see Fig. 11). 6. Reassem...
