TROUBLESHOOTING

ASSEMBLY

To avoid injury from accidental startups, turn switch OFF and remove the plug from the power source outlet before making any adjustments.

1. Unfold the front and back of the drywall sander. Push the clasp into the closed position to keep the drywall sander assembly from unfolding (Fig. A).
   
2. Attach the sanding disk of your choice to the face of the hook and loop base pad. Ensure the holes on the sanding disks align with the holes on the bottom of the pad (Fig. B).
   
3. Attach the optional handle extension by inserting the pole into the main drywall sander. Tighten the nut to lock the handle extension in place.
4. If you would like to use a dust collection device, screw the hose connection port into the end of the additional handle extension. If you choose not to use the handle extension, attach the hose connection port directly into the end of the main drywall sander assembly.
5. Connect one end of the dust hose to the end of the hose connection port and another to the dust extraction device of your choice.
   

OPERATION

1. Hold the machine with both hands.
2. Do not hold the machine by the machine's head.
3. Before operation, make sure every fastener and nut has been properly engaged and that the sanding pad has been properly installed and aligned.
4. Before switching on the machine, keep the sanding head slightly away from the work surface.
5. Do not press down too hard in order to avoid overloading the sander. Use proper pressure for better sanding effects. If the machine slows or bogs down, immediately lessen the applied pressure. The quality of the results are mainly determined by choosing the right abrasive material for the job.
6. Once the sanding task has been completed, turn off the machine. Wait for the pad to stop rotating before setting down the machine.

VARIABLE SPEED CONTROL

Use the speed wheel (Fig. D - 1) to adjust anywhere from 600 to 1500 RPM. This drywall sander is equipped with constant speed control to keep the pad running at a consistent rate despite changes in applied load.

TURNING ON THE DRYWALL SANDER

After setting the variable speed to your desired RPM, power the machine by pressing forward on the power switch (Fig. D - 2).

MAINTENANCE

REPLACE THE SANDING PAD

Insert the hex wrench into the hexagonal screw (Fig. E - 1) located in the center of the hook and loop sanding pad. Hold the pad firmly while turning the wrench to unscrew the center hex screw. Replace the pad with an identical part suited for this particular model of drywall sander. Attach firmly in place using the hexagonal screw.

CLEANING AND MAINTAINING YOUR DRYWALL SANDER

Your drywall sander requires no additional lubrication or maintenance. Always store your sander in a dry place away from children. If the supply cord is damaged, it must be replaced by the manufacturer or a similarly qualified technician. Do not use a damaged tool.

If excessive sparking occurs, have the carbon brushes checked by a qualified electrician. Only a qualified technician should change the carbon brushes.

Clean the unit immediately after using it. Regularly clean the unit with a damp cloth and a little soft soap. Do not use cleaners or solvents as they will attack the plastic of the unit. Make sure water does not get into the unit.

ELECTRICAL INFORMATION

GROUNDING INSTRUCTIONS

IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path of least resistance for an electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into a matching outlet that is properly installed and grounded in accordance with ALL local codes and ordinances.

DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper outlet installed by a licensed electrician.

IMPROPER CONNECTION of the equipment grounding conductor can result in electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or replacement of the electric cord or plug is necessary, DO NOT connect the equipment grounding conductor to a live terminal.

CHECK with a licensed electrician if you do not completely understand the grounding instructions or whether the tool is properly grounded.

USE ONLY THREE-WIRE EXTENSION CORDS that have three-pronged plugs and outlets that accept the tool's plug as shown in Fig. A. Repair or replace a damaged or worn cord immediately.

In all cases, make certain the outlet in question is properly grounded. If you are not sure, have a licensed electrician check the outlet.

This tool is for indoor use only. Do not expose to rain or use in damp locations.

Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table below shows the correct size to be used according to cord length and nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.

Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it. Protect your extension cords from sharp objects, excessive heat and damp/wet areas.

Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected with a 15 A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage the motor.

This tool must be grounded while in use to protect the operator from electric shock.
