POWER PRO Troubleshooting Guide
1. Does the battery indicator light when the button is pressed?
a. NO: Replace battery with fully charged battery. If the indicator still does not light, the problem is with the
battery terminals, the control board or the Hall Sensor Cable. Contact a service technician at (800) 327-
0770 or (269) 324-6500.
b. YES, the indicator flashes red at a constant rate. Replace battery with fully charged battery.
c. YES, the indicator flashes red with long and short flashes. This indicates an error in the electrical system.
Check all electrical connections. If this doesn't eliminate the error code, there is a connection broken at
some point in the electrical system. Please contact a service technician at (800)-327-0770 or (269) 324-
6500.
d. YES, the indicator lights solid green. Continue to number 2.
2. Does the motor turn on when the (+) button is pressed and held?
a. NO: Try the other set of switches. If this works, replace the first switch. If this doesn't work, the problem
could be a faulty A-valve solenoid, A-valve, control board, or motor. Replace these components in that
order, trying the function after each.
b. YES: Does the cot drive up, and then drift down?
i. NO: The problem is a faulty A-valve solenoid, A-valve, or motor. Replace these components in that
order, trying the function after each.
ii. YES: Continue to number 3.
3. The problem is most likely with the cap-side manual valve or the B-valve.
a. Use the manual release lever to raise and lower the cot a couple of times.
b. Push the cap-side manual valve in by tapping the stem with a punch and hammer.
c. Loosen the manual release cable until it will no longer pull the valves. If this fixes the drift, re-adjust the
manual release cable until proper function is achieved (See page 70 for how to adjust the cable).
d. Replace the B-valve.
e. Replace the cap-side manual valve.
f. If none of the above fixes the drift, the manifold may need to be replaced. Please contact a service
technician at (800) 327-0770 or (269) 324-6500.
4. For leaking hydraulic fluid, wipe the area clean so the source of the leak can be found, then tighten or replace the
leaking component.
