TYPES OF OPERATIONS

Flat surface sanding is demonstrated in Figure 16, where the major surface is sanded in a flat plane.

Edge sanding is a common type of long surface sanding that can be done using the fence. See Figure 17.

Edge sanding and flat surface sanding can also be done with the belt in a vertical position, by using the fence assembly as a table.

Miters and compound miter cuts can be sanded using the table and the optional miter gauge (available from your Powermatic dealer). Special fixtures can also be designed to use on the table for circular and form sanding.

Contour sanding can be done using the idler pulley with the end guard swung down. See figure 18.

CAUTION: Always swing the end guard

!back in position and fasten it down immediately after the completion of any operation that required the guard to be moved out of position.

!CAUTION: Keep in mind that abrasive sanding develops heat, so burns can occur on wood if

you try to remove material too fast. With metal, it may be necessary to have a container of water nearby to keep the workpiece cool enough to hold it by hand.

Flat surface and contour sanding can be done in the horizontal, 45-degree, and vertical position of the belt arm. To change position, pull out the shot pin and swing arm to the desired position, then release shot pin (Figure 11).

MAINTENANCE

Make periodic or regular inspections to ensure that your sander is properly adjusted, that all screws are tight, the belts in good condition, that dust has not collected in the motor or electrical enclosures and there are no loose or worn electrical fittings or wiring.

LUBRICATION

All bearings used on the Model 31 Sander are sealed for life and require no lubrication.

Monthly lubrication schedule:

The idler slide, Figure 19, and table trunnion (B-Fig. 8), with good quality, non-hardening grease.

The table clamp screw (A-Fig. 8 on page 9) and belt arm shot pin (B-Fig. 11 on page 10) with SAE No. 10 oil.
