Assembly and operating

Installing a sanding dis

To install a sanding disc, firmly press the sanding disc (1) onto the hook & loop pad (2) (Fig. 1).

To remove the sanding disc (1), simply peel the disc away from the hook & loop pad (2) (Fig. 2).

On/Off switch

To turn the switch ON, press the left hand side of the switch (1) (Fig. 3). To turn the switch OFF, press the right hand side of the switch (2).

Connecting the dust bag assembly to the sander

Slide the dust bag connector (1) into the dust port (2) in the rear of the detail sander(Fig. 4).

When the dust bag connector is pressed fully into the dust port, turn the dust bag approximately 15° clockwise to lock the dust bag onto the sander.

Cleaning the dust bag

Remove the dust bag assembly (1) from the dust port by rotating it counter clockwise approximately 15° and pulling it out of the dust port (Fig. 5). Carefully shake the dust bag assembly with the end cap opening (2) pointing downward to remove the sanding dust. Reinstall the dust bag assembly as noted in Fig 4.

Sanding disc selection

Make sure you select the correct size and style of sanding disc for your detail sander. The correct disc will:

Have a diameter of 5”.

Have a row of eight 3/8’’ holes that match the hole pattern in the sander base.

Have a backing for use with the hook & loop disc attachment system.

Selecting the correct grit and type of sandpaper is extremely important in achieving a high quality sanded finish. Aluminum oxide, silicon carbide and other synthetic abrasives are best for power sanding. Natural abrasives such as flint and garnet are too soft for economical use in power sanding.

In general, coarse grit will remove most material. Fine grit will produce the best finish in all sanding operations. The condition of the surface to be sanded will determine which grit will do the best job.

Sanding

Clamp or otherwise secure your workpiece to prevent it from moving under the sander while being sanded. Secure the workpiece in a vice if possible.

Place the sander on the workpiece so the complete sanding disc surface is in contact with the workpiece. Turn the sander ON by pressing on the left hand side of the ON/OFF switch. Move the sander slowly over the workpiece making successive passes in parallel lines, circles or crosswise movements. Because the random orbital motion of the sanding disc moves in tiny circles, it is not necessary to move the sander with the grain or in the same direction for successive passes (Fig. 6).

Upon completion of the sanding operation, turn sander OFF by pressing on the right hand side of the ON/OFF switch. Wait until the sanding disc comes to a complete stop before removing it from the workpiece.

Clean the dust box often

Clean the dust bag often. It will be more efficient when it is not clogged with sanding dust. To clean the dust bag, see Fig. 5.

Do not force the sander. The weight of the sander usually provides adequate pressure. Let the random orbital sander and the sanding disc do the work. Applying added pressure will slow the motor, increase the wear on the sandpaper and greatly reduce the sander speed. Excessive pressure will overload the motor causing possible damage from the motor overheating. It will also create an inferior finish on sanded work. Any finish or resin on wood will soften from the frictional heat, causing sandpaper to become clogged quickly. Do not sand in one spot too long as the tool’s rapid action may remove too much material, making the surface uneven.

Extended periods of sanding may tend to overheat the motor. If this occurs, turn the sander OFF, wait until the sanding disc comes to a complete stop and remove it from the workpiece. Check to make sure your hands have not been covering the cooling vents. Let the motor cool before continuing the sanding operation.
