Extension Cords
If an extension cord is necessary, make sure the
cord rating is suitable for the amperage listed on
the machine's motor plate. An undersize cord
will cause a drop in line voltage resulting in loss
of power and overheating.
The chart in Figure 19 shows the correct size
cord to use based on cord length and motor
plate amp rating. If in doubt, use the next
heavier gauge. The smaller the gauge number,
the heavier the cord.
Adjustments
Drum Height Control
The drum height and depth of cut are controlled
by the height adjustment handle (see Figure 5).
Rotating the handle counterclockwise lowers the
drum, clockwise raises it. One revolution of the
handle will move the drum approximately 1/16”
(or 1/4 turn = approx. 1/64”).
Switch Lock
Unauthorized use of the sander can be
prevented by pulling out the key (Figure 20).
Press switch to OFF position before removing
the key. When the key is removed, the machine
can not be started.
To replace the key, slide it back into the switch
until it snaps.
Depth Gauge
The depth gauge indicates the distance between
the bottom of the sanding drum and the top of
the conveyor surface. Adjustment is performed
by “zeroing” the gauge.
1. Loosen screw (A, Figure 21) with a 9/16”
wrench sufficiently to allow indicator needle
(B) to be turned to depth gauge scale (C).
2. With an abrasive strip on the drum, lower
sanding drum to where it touches top of
conveyor belt.
3. At this drum position, the depth gauge
indicator needle (B) should align with the
zero mark of the scale. If it does not, loosen
screw (A) and raise or lower indicator
needle to align with zero on the scale.
4. Re-tighten screw (A).
