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.
