If your vacuum cleaner requires a special connector (something other than the standard 1-1/4" to 2-1/2" connectors supplied with the Drywall Sander), contact your vacuum cleaner supplier for the proper adapter. 8 904374- 06-26-02.qxd 7/11/02 8:12 AM Page 9 TO START AND STOP DRYWALL SANDER Be certain that the power circuit voltage is the same as that shown on the specification plate of the tool, and that the switch is OFF. Connect the tool to the power circuit. The Drywall Sander is equipped with a “rocker” type switch (A) Fig. 4. The top end of the switch button is labeled “OFF”, and the bottom end of the button is labeled “ON”. To start the Sander, press the bottom (ON) end of the switch. To stop the Sander: press the top (OFF) end of the switch. SPEED CONTROL The Model 7800 Drywall Sander is equipped with a variable speed control. The speed is adjusted by turning the control knob (B) Fig. 4. The control knob is numbered “1” through “5”. The setting “1” is the slowest speed (approximately 1000 RPM) and “5” is the fastest speed (approximately 2,000 RPM). Use the higher speed settings for fast stock removal. Use the lower speed setting to reduce removal rate for more precise control. The Model 7801 Drywall Sander has a constant speed of 2,000 RPM. BRUSH-TYPE SKIRT On the Model 7800, a brush- type skirt (A) Fig. 5, surrounds the abrasive pad. This skirt serves two purposes: (1) It extends below the surface of the abrasive pad so that it contacts the work surface first, preventing the abrasive from “gouging” the work. (2) It helps contain the drywall dust until the vacuum cleaner pulls it away. Replace the skirt if it is damaged or if it is worn excessively. Replacement skirts are available from any Porter-Cable Service Center (see the list in back of this manual). Since the Model 7801 requires no vacuum cleaner, the skirt is shorter, but provides the same purpose as #1 in the preceding paragraph. Fig. 4 Fig. 5 CAUTION: DISCONNECT TOOL FROM POWER SOURCE. 9 904374- 06-26-02.qxd 7/11/02 8:12 AM Page 10 TO REPLACE SKIRT (1) Remove abrasive pad (see ABRASIVE PAD REPLACEMENT). (2) Use phillips screwdriver to remove the six retaining screws (B) Fig. 5. (3) Lift the skirt out of housing. (4) Position new skirt to housing and install the six retaining screws. (5) Replace the abrasive pad. SANDING DRYWALL The Drywall Sander has a unique articulating sanding head. the head can swivel in multiple directions, allowing the abrasive pad to conform to the work surface (Figs. 6, 7, and 8). This action enables the operator to sand the top, middle, and bottom of a wall or ceiling joint without changing position. WALL Fig. 6 CEILING Fig. 7 CEILING Fig. 8 1. Turn the vacuum cleaner switch “ON”. (Model 7800 only). CAUTION: Wear a respirator approved by NIOSH for “Dust and Mist”. 2. Turn Drywall Sander switch “ON”. 3. Position the Drywall Sander lightly against the work surface. Apply just enough pressure to align the sanding head with the work surface. 4. Apply additional pressure to engage the abrasive pad on the work surface. Move the Sander in an overlapping pattern to smooth the drywall compound down to a “featheredge”. Apply ONLY enough pressure to keep the abrasive pad flat against the work. Excessive pressure can cause unacceptable swirl marks and unevenness in the work surface. 10 904374- 06-26-02.qxd 7/11/02 8:13 AM Page 11 Keep the Sander in constant motion while the abrasive pad is in contact with the work surface. Use a steady, sweeping motion. Stopping the Sander on the work, or moving the Sander erratically can cause unacceptable swirl marks and unevenness in the work surface. NOTE: Do not allow rotating abrasive pad to contact sharp protrusions. Contact with protruding objects (nails, screws, electrical boxes, etc.), can severely damage the abrasive pad. ABRASIVE PAD REPLACEMENT CAUTION: DISCONNECT TOOL FROM POWER SOURCE. 1. Grasp the abrasive pad and the sander housing to prevent pad rotation. 2. Rotate the pad retaining nut (A) Fig. 9 counterclockwise and remove. 3. Lift off the large metal washer (B) Fig. 9, and the abrasive pad (C) Fig. 9. Fig. 9 NOTE: When the abrasive pad (C) Fig. 9 is lifted off the Sander, the abrasive back-up disc (A) Fig. 10 is exposed. Please note that this back-up disc is also covered with an abrasive material., and is used ONLY to prevent “slippage” between the back-up disc and the foam- backed abrasive pad. it is NOT suitable for use as a sanding abrasive. DO NOT USE THE SANDER WITHOUT A PROPER ABRASIVE PAD Position the new abrasive pad to the back-up disc, and center the hole of the disc on the hub (B) Fig. 10 of the back-up disc. 5. Position the large metal washer (B) Fig. 9, and the retaining nut (A) Fig. 9, to the Sander. 6. Rotate the retaining nut clockwise to hand tighten (while holding the abrasive pad as described in step 1). 11 904374- 06-26-02.qxd 7/11/02 8:13 AM Page 12 Fig. 10 TRANSPORTATION AND STORAGE Keep the Drywall Sander dry during transport and storage.
