2 Position Belt cover - Figure 2 & 3
The belt sander has an aluminum sanding belt cover at the front. When the handle is
positioned in the uppermost position, this cover can be raised as shown in Figure 2
(Arrow 1) and locked in this position to:
a.) Improve accessibility to narrow areas.
b.) Allow the use of the smaller diameter front roller to sand with (normally the aluminum
cover prevents this when in the "down" position).
c.) Expose the top part of the belt for more versatile sanding (Figure 3).
To lower the belt cover, grasp the flange on the side and move it slightly in the
direction shown in Figure 2 (Arrow 2) and return it to its closed position.
Note: The sanding belt cover cannot be locked in its raised position unless the bail handle
is in the uppermost position.
WARNING: The sanding belt is exposed when the belt cover is raised. Use extra
caution when operating in this mode.
Adjusting The Sanding Belt Tracking - Figure 4
Turn the machine upside down (Figure 4), hold it firmly with one hand, start motor and
release switch immediately after observing tracking of sanding belt. If abrasive belt runs
outward, turn tracking adjustment knob clockwise and counterclockwise if belt runs inward.
Belt life will be greatly increased by keeping the tracking adjustment set properly. To
prevent the sanding belt from rubbing against the sander housing, keep the edge of the
belt about 7/64 in. (2.7mm) to 13/64 in. (5.1mm) from the housing as shown in figure 4.
