MAINTENANCE

General Sanding Belts

Regular maintenance on your Model W1678 helps ensure optimum performance. Inspect your machine each time you use it for the following conditions. Adjust, repair, or replace parts when worn.

1.Inspect for loose bolts and panels.

2.Make sure the work area is clean, and remove any tools or rags from the machine.

3.Replace worn electrical parts like the emergency stop switch, ON and OFF push buttons, and damaged cords and plugs.

4.Replace damaged sandpaper, motor V-belts, or conveyor drive chains and sprockets.

5.Correct any other condition that could hamper the safe operation of this machine.

6.Routinely clean the sandpaper with a PRO-STIK®15" x 20" cleaning pad shown in Figure 51.

As sanding drums are used, the sandpaper can quickly become "loaded" with sawdust. If not removed, this sawdust may harden on the abrasive surface and can glaze instead of sand the wood, thus, rendering the sandpaper useless.

To avoid this condition, routinely clean the sandpaper with a rubber gum abrasive cleaner such as the D3003 PRO-STIK®15" x 20" cleaning pad shown in Figure 51. to extend the life of the sandpaper.

The Model W1678 allows you to use two different grit sandpapers at once. The first drum is fitted with a coarser grit than the second. Usually this translates into combinations of successive group types. A common selection for a workpiece that is planed before it is sanded, is the 100/150 grit combination.

Overall, the general rule of thumb is to sand a workpiece with sandpaper that uses progressively higher grit numbers, with no one grit increase of more than 50.

Ultimately, the type of wood you use and your stage of finish will determine the best grit types to install on your sander.
