Never use an adapter to
connect the three-prong electrical plug to a non-
grounded, 2-pole receptacle. Do not modify the
plug provided. Improper connection of the
grounding conductor can result in a risk of
electric shock.
Check with a qualified
electrician or service person if you do not
completely
understand
these
grounding
instructions or if the proper grounding of this
tool is in doubt. Failure to comply may cause
serious or fatal injury.
Repair or replace damaged or worn cord
immediately.
7.2
Extension Cords
The use of extension cords is discouraged; try to
position machines near the power source. If an
extension cord is necessary, make sure it is in good
condition. When using an extension cord, be sure to
use one heavy enough to carry the current your
product will draw. An undersized cord will cause a
drop in line voltage resulting in loss of power and
overheating. Table 1 shows correct size to use
depending on cord length and nameplate ampere
rating. If in doubt, use the next heavier gauge. The
smaller the gauge number, the heavier the cord.

Adjustments
Disconnect sander from power
source before making adjustments.
8.1
Drum Height Control
Drum height and depth of cut are controlled by
height adjustment handle (see Figure 5-1). Rotating
handle clockwise lowers drum, counterclockwise
raises it. One revolution of handle will move drum
approximately 1/16” (or 1/4 turn = approx. 1/64”), as
shown on the label below handle.
8.2
Depth Scale
The depth scale indicates distance between bottom
of sanding drum and top of conveyor belt.

Conveyor Belt Tension/Tracking
Conveyor belt tension adjustment may be
necessary during the break-in period to compensate
for belt stretching.
