Installing the Trackers
TM
Trackers dramatically reduce tracking
adjustments of the conveyor belt by guiding the
belt towards the center of the rollers and by
keeping the belt from running off the rollers.
The Trackers are installed on the underside of
the conveyor belt as follows:
1. Disconnect the machine from the power
source.
2. Raise the sanding drum to its highest
position (see
Drum Height Control
on
page 11).
3. Remove the tension from the conveyor belt
(
Conveyor Belt Tension
on page 11).
4. Referring to Figures 2 and 3: The tracker is
positioned on the underside of the conveyor
belt, on the infeed side of the sander,
(closest to the rubber covered drive roller
and gear motor). The back of the tracker is
magnetized and will stick to the sidewall of
the conveyor bed. Do not install the tracker if
the edge of the conveyor belt is damaged of
torn.
5. When the tracker is installed, slide the
conveyor belt into the bottom slot of the
tracker.
Note:
When installed properly, only the
bottom lip of the tracker will be visible. The
top slot is to be used if the bottom slot wears
out.
6. When installing the second tracker, repeat
steps four and five. Use both trackers unless
the conveyor belt is damaged.
7.
Make sure all of the switches are off.
Reconnect the power to the machin
e.
8.
Tension the conveyor belt (see Conveyor
Belt Tension
on page 11). With both trackers
installed, it is very important to have equal
tension on both sides of the conveyor belt.
Tighten both sides of the adjustment screws
until equal tension is obtained.
9. Turn the conveyor on full speed and
carefully place both hands on the conveyor
belt to check the tension. If the conveyor belt
can be stopped, continue increasing the
tension until the conveyor belt cannot be
stopped by placing both hands on the belt
while the conveyor is operating at full speed.
10. Continue to watch the tracking of the
conveyor belt and adjust it only if necessary;
do not allow the conveyor belt to buckle
under the conveyor bed.
