ELECTRIC SYSTEM SERVICING

It is necessary to use a voltmeter and an ohmmeter
to perform the simple servicing procedures.
MEASURING RESISTANCE (OHMMETER)
1) Disconnect the power supply.
2) Set the ohmmeter at x1000
scale and keep it there for
all resistance reading.
3) Touch the two probes
together and "zero" the
ohmmeter.
ELECTRICAL SERVICING
If the power switch is on and the rolls do not turn,
follow the procedure outlined below.
1)
Check the power supply for 110 volts.
2)
CAUTION: This troubleshooting step requires
bypassing the safety switches. Be extremely
careful to keep hands and clothing away from
any moving parts or electrical connections.
Remove the top cover. Remove the screws
retaining the inner panel with the guard inter-
lock attached. Let this panel hang. Depress
each microswitch placing a shim between the
microswitch button and the flange the button
protrudes through. With power on, read voltage
across 1 and 2 on terminal strip.
If the voltmeter reads: 110 volts, proceed to
Step 3.
If the voltmeter reads: "0" V: the problem is
either broken wires from the power supply to the
power switch or a defective power switch.

With the power on, read the voltage across 1
and 3 on the terminal strip.
If the voltmeter reads: 110 volts, proceed to
Step 4.

Replace the panel and the cover. Remove the

motor side cover. With the power on, check
whether the motor is turning or not. If the motor
does turn, check that the keys and set screws
in the sprocket are in position and tight. If the
motor does not turn, check that the reducer is
not bound up - replace the motor.
