• Make sure that the voltage of the power supply circuit is the same as the one indicated on the sander's nameplate and that the sander's circuit breaker is
turned o. Connect the sander to the power supply circuit.
• The sander is equipped with a suitable locking switch. Press the switch No.1 as shown in the gure below. Do not loosen your hand. If the tool is in the "ON"
posion, pressing the lockout switch will sll turn the tool on.
• Press the switch again and the lock will be turned o.

• The drywall sander is equipped with variable speed control. The speed is adjusted by turning the control knob. The
control knob goes from "MIN" to "MAX" (from the slowest speed to the fastest speed: 1000-2100 rpm).
• Use the higher speed sengs for quick removal. Use the lower speed sengs to reduce the rate of removal for beer
control.

A special type brush, as shown below, surrounds the abrasive pad No.3. This brush serves two purposes:
• It extends under the surface of the abrasive tread, so that it rst makes contact with the work surface. This places the abrasive head parallel to the work
surface before the abrasive contacts the workpiece, thus prevenng "etching".
• The special apron also helps to retain the drywall dust unl the vacuum cleaner removes it.
CAUTION! Disconnect the sander from the power circuit.
To replace the apron:
• Remove the abrasive pad.
• Use a suitable screwdriver to remove the apron from the housing and secure the new apron
• to the housing with a plasc clip.

The drywall sander has a unique arculated sanding head. The head can rotate in mulple direcons, allowing the sanding pad to adapt to the work surface
(see A/B/C below). This allows the operator to sand the top, middle and boom of a wall or ceiling without changing its posion.
• Turn on the vacuum cleaner switch.
CAUTION! Wear an approved "dust and mist" mask.
• Turn the drywall sander switch to ON.
• Place the drywall sander lightly on the work surface (apply enough pressure to align the sanding head with the work surface).
• Apply addional pressure to engage the sanding pad to the work surface.
• Apply ONLY enough pressure to keep the abrasive pad at on the workpiece. Excessive pressure may cause swirl marks and unevenness on the work surface.
• Keep the sander in constant moon while the abrasive pad is in contact with the work surface. Use a steady, sweeping moon.
• Stopping the sander (on the work) or errac sander movement can cause swirl marks and unevenness on the work surface.
NOTE: Do not allow the rotang abrasive pad to come in contact with sharp projecons. Contact with protruding objects (nails, screws, electrical boxes, etc.)
can cause serious damage to the abrasive pad.

ATTENTION! Disconnect the sander from the power circuit.
• To prevent the pad from becoming detached, grasp the abrasive pad and the sander housing, securing the pad rmly to the housing.
• Secure the nut with the inner hex and rotate the pad retaining nut.
• Li up the large metal washer, and the abrasive pad.
NOTE: When the abrasive pad is lied o the sander, the backup sanding disc is exposed. Keep in mind that this backup disc is also covered with abrasive material.
This abrasive material is ONLY used to prevent "slippage" between the backup disc and the foam backed abrasive pad, it is NOT suitable for use as a grinding material.
• Place the new abrasive pad on the spare disc, making sure that the center hole of the abrasive pad is centered in the spare disc.
• Place the large metal washer and nut on the sander.
• Rotate the nut clockwise to ghten it by hand while holding the abrasive pad as described above.
