WARNING: Electrical wiring should be done
by a qualified electrician. The machine must
be properly grounded to help avoid electrical shock
and associated hazards including possible death.
ADJUSTMENTS
Before putting power to the sander, inspect the machine
thoroughly. Check to ensure that all screws are tight, all
mechanical functions work freely, belt runs freely and
tracks properly, and the disc runs freely and does not
come into contact with the guard or table.
Turn the motor on and check for proper rotation direction
of the belts. The sanding belt should move from the
idler pulley toward the drive pulley while the disc should
rotate counter-clockwise with the operator facing the
disc.
Run the sander without sanding for a short period to
ensure the belt tracks properly and the disc adhesive
sticks properly to the disc.
ABRASIVE BELT INSTALLATION
To install or replace an abrasive belt, proceed as follows
(Figures 5 and 6):
1. Loosen the knob (A) and swing the belt end guard
(B) out of position.
2. Remove the side guard (C) by loosening and
removing the two screws holding it. Release tension on
the belt by loosening the tension knob (E) at the back of
the belt arm. Loosen the tracking screw (F) on the side of
the belt arm and move the drum forward.
3. Slide the worn sanding belt off the idler and driving
drums and install a new belt.
4. Retighten the belt tension screw (E) and tracking
screw (F). Check the tracking manually to ensure the belt
tracks properly. Put the side guard (C) back on and
secure with the screws. Swing the end guard (B) back
into position and re-tighten the knob (A).
ABRASIVE BELT ALIGNMENT
1. To properly align the abrasive belt, tighten the belt
tension screw (E) until the belt is relatively tight. See
Figure 5.
2. Manually rotate the belt with one hand while at the
same time adjusting the tracking screws with the other
hand until the belt is tracking in the center of the idler and
driving pulley. Caution is necessary since excessive
tension can stretch a belt to the point where it will not
track.
