Diagram Description (Fig 7): Shows the speed adjustment dial on the sander's motor housing. Arrows indicate turning the dial towards "6" to increase speed and towards "1" to decrease speed.

Selecting Sanding Discs

Selecting the correct size grit and type of sanding disc is an extremely important step 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 power sanding. In general, when sanding, coarse grit removes the most material and fine grit produces the best finish. The condition of the surface to be sanded determines which grit will do the best job. If the surface is rough, start with a coarse grit and sand until the surface is uniform. Then use medium grit to remove scratches left by the coarser grit. Finally, use finer grit for finishing the surface. Always continue sanding with each grit until the surface is uniform.

Attaching Sanding Discs (See Figure 8)

Warning: Failure to switch off the tool and remove battery pack could result in accidental starting causing possible serious injury.

Note: You can reuse hook-and-loop type sanding discs for the life of the sanding abrasive. We recommend that you clean the backing pad occasionally by brushing it lightly with a small brush for best adhesion.

Changing the Sanding Discs

The sander is packed with sanding sheets and pads designed for a variety of uses. To change, simply pull the used sheet or pad off the base and attach the desired sheet or pad by pressing it onto the base of the sander.

Using the Dust Canister

The dust canister provides a dust collection system for the sander. Sanding dust is drawn up through the holes of the sanding disc and collected in the dust canister during sanding.

Removing and Installing Dust Canister (Fig. 9)

Diagram Description (Fig 9): Shows the dust canister being removed from the sander's dust port. It highlights the dust port and the dust canister, showing how they connect.

Warning: Failure to switch off the tool and remove battery pack could result in accidental starting causing possible serious injury.

Cleaning and Emptying the Dust Canister

For more efficient operation, empty the dust canister when it is no more than half full. This will permit the air to flow through the canister better. Always empty and clean the dust canister thoroughly upon completion of a sanding operation and before placing the sander in storage.

To empty canister, remove dust canister and pour out the dust inside.

Note: Do not wash the micro filter with soap and water. Dust may become more firmly lodged in the pores, which will reduce dust collection, and damage the micro filter.

Operating the Sander (Figures 10 and 11)

  1. Follow these steps to operate the sander.
  2. Secure the work to prevent it from moving under the sander.
  3. Keep your head away from the sander and the sanding area. Your hair could be drawn into the sander causing serious injury.
  4. Place the sander on the workpiece so that all of the sanding disc surface is in contact with the workpiece.

Warning: Unsecured workpieces could be thrown towards the operator causing injury.

Warning: Keep your head away from the sander and the sanding area. Your hair could be drawn into the sander causing serious injury.
