MAINTENANCE PROCEDURES

Your Oscillating Edge Sander requires little

maintenance beyond the routine inspection,

lubrication, and cleaning.

ROUTINE INSPECTION

It is a good idea to routinely inspect any quality

woodworking tool in order to keep it in optimum

condition. This includes inspecting all hardware for

tightness, ensuring drive belts are in good condition,

and cleaning debris and grime from any surfaces and

moving parts.

LUBRICATION

The sealed motor of your Oscillating Edge Sander

is maintenance-free. However, it is recommended

that you periodically lubricate the gears in the gear

box using a quality #2 grease or equivalent. To keep

the sander table and other bare metal parts in good

working condition, apply an occasional coat of quality

paste wax, free of silicone or synthetics

CLEANING THE SANDING BELT

Regularly inspect and, if necessary, clean the sanding

belt with a high quality gum rubber belt cleaner. If you

notice sanding performance is significantly decreasing,

it may be time to replace the sanding belt. Refer to

directions on page 11.
