Models 29 & 35: Troubleshooting Guide
For each symptom, run through steps in order shown.
Electrical Problems
2.
Key On Gets "Click", and Green Light Comes On, But Pushing or Pulling on
Bail gets No Action.
A.
Be sure forward/reverse bail circuit wiring and speed rheostate wiring is all tight and
unbroken.
Note that the speed-selecting rheostat may need periodic cleaning in some ex
treme work environments. To do
this, use "Contact Cleaner" only, the kind
used to clean radio and TV tuners. Open the Central Command, and spray some
carefully down the shaft of the rheostat Cleaning almost always solves a rheo
stat problem.
If you think the problem is in the speed-selecting rheostat, please call 1-800-634-
4060 for a test procedure to verify its condition.
B.
Replace Central Command.
C.
If still a problem, call 1-800-634-4060 for advice.
3.
Machine Runs Fine in Forward, But Cannot Be Shifted Into Reverse.
A.
Remove Rear Control Panel from Central Command and Check both mechanical
Connection between bail and forward reverse switch and the electrical contacts.
This switch receives power from the key switch, and sends it back to Central Com
mand's microprocessor. No power = forward; power on = reverse.
B.
Check Switch Output.
C.
Replace Central Command.
