PROBLEM
POSSIBLE CAUSES
CORRECTIVE ACTION
Actuators don’t hold charge.
New actuators.
It may be necessary to 100
-
200 lifts
before the actuators hold their
charge due to internal lubrication.
Actuators run backwards
Switch wires reversed.
Recheck wiring.
Battery wires reversed.
Recheck wiring.
Actuators (or one) will not
operate
Ignition switch is at OFF position.
Turn ignition switch at ON position.
Broken wires or bad connection.
Check for poor connections.
Control switch is inoperative.
Replace control switch.
Relay or breaker is damaged.
Replace the relay or breaker.
Actuators are damaged.
Replace or repair actuators.
Actuators run but with
insufficient power or line speed.
Weak battery.
Recharge or replace battery.
Check charging system.
Poor battery connection.
Check battery terminals for
corrosion. Clean when required.
Actuators are damaged.
Replace or repair actuators.
HOW TO KNOW
POINTS TO CHECK
Actuators are damaged.
The ultimate test is to connect the actuators directly to the battery and
reverse the wires to test both directions. If the actuators don't work, they
are damaged.
The breaker is damaged.
Check the resistance with multimeter on both terminals of the breaker. If no
contact, replace the breaker. (Sometimes, it could take a few minutes for
the breaker to automatically reset itself).
