OPERATION
HOW TO HOLD A DRYWALL SANDER
The drywall sander should be held with both hands on
the main tube. The hands may be positioned anywhere
along the main tube to provide the best combination of
reach and leverage for the particular application.
CAUTION
Keep hands on Main Tube. Do not place hand into area
around the sanding head. The sanding heads swivels in
multiple directions and could pinch hand.
CONNECT DRYWALL SANDER TO VACUUM
CLEANER
The following items are furnished with the drywall sand-
er (Fig. 3, 4).
One vacuum hose: 4m long (includes a standard 38mm
vacuum cleaner connector on end and a special swivel
connector on the sander end), with a static dissipating
feature to dissipate static electrical charges that are
sometimes experienced when recovering drywall dust.
One 38mm to 47mm adapter (adapts the 38mm hose
connector to fit a 47mm vacuum cleaner).
INSTALL AS FOLLOWS:
1. Install a special drywall dust bag into your vacuum
cleaner, following the instructions supplied with
the vacuum cleaner.
2. CAUTION:
Failure to use a vacuum cleaner rated for drywall
dust will increase the level of airborne dust par-
ticles in the work area. Continued and prolonged
exposure to high concentrations of airborne dust
may affect the respiratory system function.

3. Connect the vacuum hose to the drywall sander.
Open the drywall sander's hose connector by
turning the large nut counterclockwise a couple
of turns. Push the vacuum hose swivel connector
into the drywall sander connector and seal firmly.
Turn the large nut clockwise to tighten connector.
4. Install the six "hook & loop" type straps, to pre-
vent tangling of the sander cord and the vacuum
hose. Lay the cord and the vacuum hose out paral-
lel to each other. Space the straps at approximate-
ly two foot intervals, beginning two feet from the
drywall sander. Wrap the long end of each strap
around the vacuum hose and close. Then wrap the
short end of each strap around the cord and close.
5. Connect the vacuum hose to your vacuum clean-
er: Use the 38mm to 47mm adapter if necessary,
if your vacuum cleaner requires a special connec-
tor (something other than the standard 38mm to
47mm connectors supplied with the drywall sand-
er), contact your vacuum cleaner supplier for the
proper adapter.
TO START AND STOP DRYWALL SANDER
Make sure power circuit voltage is the same as shown on
the specification plate on the sander, and that the
Sander's switch is OFF. Connect Sander to power circuit.
The drywall sander is equipped with finger touch switch.
Please see as below picture shown:
To connect with electric power, press the power button,
then press the on / off switch to turn on the machine.
Press the on / off switch again to turn off the machine.
Switch off the power by pressing the power button.
SPEED CONTROL (Fig. 2.7)
The drywall sander is equipped with a variable speed
control. The speed is adjusted by "+","-" from numbered
"1" through "7" with "1" being the slowest speed (approx-
imately 900 rpm) and "7" being the fastest speed (approx-
imately 2100 rpm).Use the higher speed settings for fast
stock removal. Use the lower speed selling to reduce
removal rate for more precise control.
BRUSH-TYPE SKIRT
A brush-type skirt surrounds the abrasive pad and it
serves two purposes: (1) it extends below the surface of
the abrasive pad so that it contacts the work surface first.
This positions the sanding head parallel to the work sur-
face, before the abrasive contacts the work surface, pre-
venting the abrasive from "gouging" the work surface. (2)
it also helps contain the drywall dust until the vacuum
cleaner pulls it away.
CAUTION
DISCONNECT SANDER FROM POWER CIRCUIT
To replace the brush-type skirt: (1) Remove abrasive pad
(see ABRASIVE PAD REPLACEMENT). (2) Use Phillips
screwdriver to remove the six retaining screws (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 .This
enables the operator to sand the top, middle and bottom
