Installing an Additional Ring

When the sanding pad is below the level of the plastic cover, please insert the back-up ring, to raise the height of

the sanding pad.

Speed Adjustment

The sanding speed can be adjusted according to different conditions and sanding quality requirements.

The Drywall Sander is equipped with a variable speed control. The speed is adjusted by turning the control knob.

The control knob is numbered 1 through 6 with ‘1’ being the slowest speed (Approximately 1500 RPM) and ‘6’

being the fastest speed approximately 3000 RPM).

Use the higher speed settings for fast stock removal. Use the lower speed setting to reduce removal rate for

more precise control.

Turn ON/OFF

Make sure that the power circuit voltage is the same, as shown on

the specification plate on the Sander, and that the Sander switch is

OFF. Connect Sander to the power circuit.

The Drywall Sander is equipped with a safety ON/OFF trigger

switch. Push the front small trigger (Step1), and then press the

bigger button (Step2) to start the machine. Then release the button

to turn OFF the machine.

Sanding Drywall

The Drywall Sander has a unique articulating sanding head: the abrasive pad to conform to the work surface.

This enables the operator to sand the top, middle and bottom of a wall or ceiling joint. When sanding a tall wall

and ceiling, please use a ladder.

The sanding pad’s height could be adjusted by itself when it meets an uneven wall.

CAUTION: Wear a respirator approved for Dust and Mist.

1. Turn Drywall Sander switch ON.

2. Position the Drywall Sander lightly against the work surface (apply just enough pressure to align the sanding

head with the work surface).

3. Apply additional pressure to engage the abrasive pad to the work surface while moving 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.

Keep the Sander in constant motion while abrasive pad is in contact with the work surface. Use a steady,

sweeping motion. Stopping the Sander (on the work area) 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.
