PROBLEM SOLUTION
Bed will not lift heavier
bales/arms will not release
bale when suspended in air
Turn the counter-balance valve ¼ turns clockwise until bale lifts
properly. Do not tighten screw all the way in. If problem persists,
turn pressure relief set screw in ¼ turn clockwise until bale lifts
properly. Do not tighten screw all the way in. If problem still per-
sists then power unit is failing.
Bale shutters or falls too fast Turn the counter-balance valve ¼ turn clockwise until bale goes
down properly. Do not tighten screw all the way in.
Bale goes down too fast Turn counter-balance valve ¼ turn counter clockwise until desired
speed is achieved. If bale starts to shutter/go down too fast, turn
same screw clockwise ¼ turn.
Fluid leaking under bed or in
tool box
Check hose connection at leak. Tighten or replace if needed.
Leaks in tool box are best diagnosed by activating the remote
while watching the power unit. Determine where the leak is com-
ing from and replace O-ring / plug / valve if needed. Some leaks
are fixed by tightening the plug/valve. Make sure the plastic res -
ervoir is not cracked.
How to Check
Solenoid Check the two posts. If posts show voltage, then the solenoid is good.
Pump Make sure there is good voltage to the motor. If motor checks out good check for
broken or worn gear. If there is a grinding or metallic noise, the pump needs to be
replaced.
Motor Check amp range using chart below. Arm & spike beds draw different amps at
different pressures.
