Tracker kit
Stock No.: PM2244‐213
Trackers dramatically reduce tracking adjustments of
conveyor belts. They are already installed on your
sander. The following information is for resetting or
replacing your trackers, should that become
necessary.
1.
Disconnect sander from power source/unplug.
2.
Raise drum as high as it will go.
3.
Turn both conveyor take‐up screws to relieve
conveyor belt tension and slide driven roller fully
inward.
4.
Remove the 2 bolts and loosen 2 wing screws
holding conveyor table to sander base.
5.
Lift conveyor table and slide it out of sander.
Turn conveyor table upside down. Be careful not
to damage conveyor belt.
6.
On the underside of the conveyor table, there
are U‐channels welded to the table. The Tracker
is positioned on the inside of the first U‐channel
on the infeed side of sander (Figure 11‐1). The
back of tracker is magnetized and will stick to
side wall of conveyor table. Do not install tracker
if edge of conveyor belt is damaged or torn.
Figure 11‐1: Underside of conveyor shown
7.
With first tracker installed, slide conveyor belt
into bottom slot of tracker.
Note:
When installed
properly, only bottom lip of tracker will be
visible. The top slot can be used if bottom slot
wears out.
8.
Install second tracker opposite the first. Use both
trackers unless the second one does not fit in
conveyor or unless conveyor belt is damaged.
9.
Turn conveyor table right‐side up and reposition
it onto sander. Re‐attach three mounting screws
and tighten.
Caution:
Be careful not to knock
tracker(s) out of conveyor table when turning
conveyor over. Trackers may break if allowed to
fall.
10.
Make sure all switches are off. Connect power to
sander and plug in motor.
11.
Tension conveyor belt using take‐up screws. If
both trackers are installed, it is very important to
have equal tension on both sides of conveyor
