Tracker Kit (98-0080)
Trackers dramatically reduce tracking adjust-
ments of conveyor belts. They are already
installed on your sander. The following
information is for re-setting or replacing your
trackers, should that become necessary. Refer
to Figure 32.
1. Disconnect power to sander, and disconnect
motor cord from control box receptacle.
2. Raise drum as far as it will go.
3. Loosen the conveyor take-up screw nuts to
relieve conveyor belt tension and slide
driven roller fully inward. Slide conveyor belt
to one side of bed.
4. Remove the four bolts holding the conveyor
table to the sander base.
5. Lift conveyor bed and slide it out of the
sander. Turn conveyor bed upside down. Be
careful not to damage the conveyor belt.
6. On the underside of the conveyor bed, there
are U-channels welded to the bed. The
Tracker is positioned on the inside of the
first U-channel on the infeed side of sander
(the U-channel closest to the rubber covered
drive roller and gear motor). The back of the
Tracker is magnetized and will stick to the
side wall of the conveyor bed. Do not install
Tracker if the edge of the conveyor belt is
damaged or torn.
7. With the first Tracker 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.
8. Install second Tracker opposite the first. Use
both Trackers unless the second one does
not fit in conveyor or if conveyor belt is
damaged.
9. Turn conveyor bed right side up and re-
position the bed onto the base. Re-attach
the four mounting bolts and tighten.
Caution: Be careful not to knock Tracker(s)
out of conveyor bed when turning conveyor
over.
10. Make sure all switches are off. Connect
power to sander and plug in motor.
11. Tension conveyor belt using take-up screw
nuts. If both Trackers are installed, it is very
important to have equal tension on both
sides of the conveyor belt. Tighten both
sides of take-up screw nuts until equal
tension is obtained.
12. To check tension, turn on conveyor full
speed and place both hands on conveyor. If
conveyor belt can be stopped, continue
tensioning until conveyor belt cannot be
stopped by both hands on the belt while the
conveyor is operating at full speed.
13. Make sure conveyor belt runs smoothly
inside Tracker slot and that magnet is
holding the Tracker in position.
14. Continue to watch tracking of conveyor and
adjust only if necessary, making sure to
keep equal tension on conveyor belt at all
times and not allowing conveyor belt to
buckle under conveyor bed.
