machine is start ed or operat ed.

37. Keep your hands clear when feeding parts onto the conveyor. The part will be forced down as it

begins to feed into the machine, causing a pinching action between the part and the table. Use

running machine. Turn off the electrical power and stop the machine before attempting to retrieve
parts f r om w ithin it. Keep your hands away f r om the sanding area. Contact with inter nal moving parts

Installing the Trackers

TM

Trackers dramatically reduce tracking
adjustments of t he conveyor belt by guiding the
belt towards the center of the rollers and by
keeping the belt fr om running off t he 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 te nsio n from the c onveyor belt

(Conveyor Belt Tensi on on page 11).

4. Refer ring to Fi gures 2 a nd 3: T he tr acker is

positioned on t he underside of t he conveyor
belt, on the infeed side of the sander,
(closest to the rubber covered drive roller
and gear motor) . The back of the tr acker is
magnetized a nd will stick to t he sidewall of
the conveyor bed. Do not install t he tracker if
the edge of the co nveyor 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
bot tom lip of the tr acker will be visib le. T he
top slot is to be used if the bottom slot w ear s
out.

6. When installing the second tracker, repeat

steps f our and five. Use bot h track er s unless
the conveyor belt is damaged.

Conveyor Drive Motor

7. Make sure all of the switches are off.

Reconnect the power t o the machine.

8. Tension the conveyor belt (see Conveyor

Belt Tension on page 11). Wit h both trackers
installed, it is very important to have equal
tension on both sides of the conveyor belt.
Tighten both sides of the adjustme nt screw s
until equal tension is obtained.

9. Turn the conveyor on full speed and

carefully place both hands o n t he co nveyor
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 f ull speed.

10. Continue to watch the tracking of the

conveyor belt and adjust it o nly if necess ar y;
do not allow the conveyor belt to buckle
under the conveyor bed.
