Extension Cords

If an extension c or d is necessary, mak e sure t he
cord r ating i s suit able f or the am perage listed on
the machine's motor plate. An undersize cord
will cause a drop in line v oltage 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 cor d.

Adjustments

Drum Height Control

The drum height and depth of cut are controll ed
by the height adjustment handle (see Figure 5).
Rotat i ng the handl e count ercloc kwise lowers the
drum, clockwise raises it. One revolution of the
handle will move the drum approximately 1/16”
(or 1/4 tur n = 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 . W hen the key is rem oved, the machi ne
can not be st ar ted.
To replace the key, slide it back into the switch
until it snaps.

Depth Gauge

The dept h gauge indicates the di stanc e between
the bottom of the sanding drum and the top of
the conveyor surface. Adjustment is performed
by “z er oing” the gauge.
1. Loosen screw (A, Figure 21) with a 9/16”
wrench sufficiently to allow indicator needle
(B) to be tur ned 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 m ar k of t he scale. If it does not, loosen
screw (A) and raise or lower indicator
needle to ali gn with zero on the scale.
4. Re-tight en screw (A) .
