4. Sanding of lead-based paint is not recommended. Lead-based paint should only be removed by a professional. 5. Always keep the base of the sander in contact with a secure workpiece to prevent loss of control. 6. Do not operate Oscillating Sander without all guards and covers securely in place. 7. Some wood contains preservatives which can be toxic. Take extra care to prevent inhalation and skin contact when working with these materials. Request, and follow, any safety information available fro

In addition, it might cause the sander to jump on the work. Let the sander do the work. FINE FINISHING The action of the Porter-Cable Finishing Sander causes thousands of tiny abrasive grits to move in circular orbits against the work at high speed. Each grain moves in the same direction at a constant speed so the cutting action is uniform over the entire pad surface. Crossing and re-crossing of the abrasive grits from all directions quickly levels surface irregularities to a fine, uniform smoot

KEEP FOOD AND DRINK out of the work area. Wash hands, arms, and face and rinse mouth before eating or drinking. Do not smoke or chew gum or tobacco in the work area. 8. CLEAN UP ALL REMOVED PAINT and dust by wet mopping the floors. Use a wet cloth to clean all walls, sills and any other surfaces where paint or dust is clinging. DO NOT SWEEP, DRY DUST OR VACUUM. Use a high phosphate detergent or trisodium (TSP) to wash and mop areas. 9. AT THE END OF EACH WORK SESSION put the paint chips and debr

4. Remove adjusting keys or wrenches before turning the tool ON. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury. 5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enable better control of the tool in unexpected situations. 6. Use safety equipment. Always wear eye protection. Dust mask, nonskid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. TOOLS USE AND CARE 1

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

Align the dust extraction holes in paper with holes in pad (334 ONLY). 5. Press disc firmly onto pad. 6. Position machine with abrasive contacting

2. Install the abrasive to the sander as described in the ATTACHING STIKIT™ ABRASIVE section, or the ATTACHING CONVENTIONAL ABRASIVE section of this manual. 3. Position the sander to the punch (see Fig. 6), aligning the sander pad with the two corner guides on the punch. Push sander onto the punch until seated (see Fig. 7). 4. Remove sander from punch.

cutting full sized (9" x 11") sandpaper into 1/4 sheets of 4-1/2" x 5-1/2". b. cutting 1/2 sheet sandpaper into two 4-1/2" x 5 1/2" sheets. Pre-cut 4-1/2" x 5-1/2" sandpaper is available at extra cost. For normal operations, to attach the abrasive paper to your unit: 1. Soften the stiff sandpaper by pulling it over the 90° edge of a table or other straight edge (Fig. 1). Concentrate on softening the edges that will be clamped. 2. Release the front and rear clamps by pulling up on the clamp lever

Aluminum oxide is the softer of the two, but is tougher and more suited for woods and soft (non-ferrous) metals. Silicon carbide is extremely hard and is best suited for surfacing stone, marble, and glass. Abrasives are classed as open-coated (with grits spaced apart), or closed- coated (with grits close together). Closed coatings provide hard, fast cutting action for hardwoods and dense metals, while open coatings are more suited to soft materials and painted surfaces. To obtain the best finish

If the joint is slightly uneven, use a fine abrasive and very light sanding pressure to get it smooth before making the finishing runs. For lengthy work on walls or other vertical surfaces, the sander can be counterbalanced with a length of sash cord, two small pulleys, a light wood frame and a weight the same as or slightly less than the weight of the sander. The frame consists of two pieces leaned against the wall with a third piece nailed across their top ends. The two pulleys are located so
