For a service parts list or to learn more about Porter-Cable visit our website at: com MOTOR Many Porter-Cable tools will operate on either D.C., or single phase 25 to 60 cycle A.C. current and voltage within plus or minus 5 percent of that shown on the specification plate on the tool. Several models, however, are designed for A.C. current only. Refer to the specification plate on your tool for proper voltage and current rating. Do not operate your tool on a current on which the voltage is not within correct limits. Do not operate tools rated A.C. only on D.C. current. To do so may seriously damage the tool. 6 EXTENSION CORD SELECTION If an extension cord is used, make sure the conductor size is large enough to prevent excessive voltage drop which will cause loss of power and possible motor damage. A table of recommended extension cord sizes will be found in this section. This table is based on limiting line voltage drop to 5 volts (10 volts for 230 volts) at 150% of rated amperes. If an extension cord is to be used outdoors it must be marked with the suffix W-A or W following the cord type designation. For example – SJTW-A to indicate it is acceptable for outdoor use.

Used as a Random Orbit Sander the tool provides rapid stock removal with 80 to 100 grit paper and swirl-free finishing with 120 to 150 grit paper. ASSEMBLY AUXILIARY HANDLE An auxiliary handle (A), Fig. 1, is furnished with the tool. The auxiliary handle may be installed on either side of the front housing to facilitate either right-handed or left-handed operation. THIS HANDLE SHOULD BE USED AT ALL TIMES TO MAINTAIN COMPLETE CONTROL OF THE TOOL. Fig. 1 A 7 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 future confusion. 8. The polishing pad is designed for product application only. Remove product residue with a soft cotton towel. Fig. 3 INSTALLING/REMOVING ABRASIVE DISC DISCONNECT TOOL FROM POWER SOURCE. 1. 2. Place machine on workbench with pad up (See Fig. 4). Fig. 4 3. Clean dust from pad face. 4. Tear a new abrasive disc from roll and position disc to the sander pad. 5. Press disc firmly onto pad. 6. Position machine with abrasive contacting scrap material. Start machine and operate momentarily while exerting firm pressure to seat disc to pad. Failure to properly seat disc to pad may result in disc being thrown from pad causing personal injury. 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. USING THE SANDER 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. 1. 9 Fig. 5 Wear ANSI Z87.1 safety glasses and dust mask. 3. Place sander to work (see Fig. 5) with abrasive disc resting FLAT on the work. NOTE: The Random Orbit mechanism allows the sander to be started and stopped with the pad in contact with the work or clear of the work. 4. Grasp sander firmly and move switch to “ON” position. 5. Keep sanding disc FLAT on work and move sander in long overlapping strokes. Tipping sander or stopping in one spot can produce an uneven finish. 6. When finished, stop sander and allow pad rotation to stop completely before setting sander down. CHANGING BACK-UP PAD DISCONNECT TOOL FROM POWER SOURCE. 2. Position spindle wrench (A), Fig. 6, (furnished with tool) to engage the flats on the spindle (B), Fig. 6. NOTES: A. It may be necessary to rotate the pad (by hand) to expose the spindle flats. B. Fig. 6 shows tool with pad removed for clarity. C. A spacer (not shown) has been supplied with the 7336SP and 7424 to add space for the backup pad to clear the eccentric plate screws (C) Fig. 6. Remove the spacer from the package and mount it on the shaft before applying the backup pad. 3. While holding the spindle with the wrench, rotate the pad counterclockwise (by hand) to remove. 4. To install pad, rev...
