PLATFORM WILL NOT RAISE, MOTOR RUNS
1.
Raise the Platform to bed height. Fill the Reservoir to about the middle. Do
not overfill as this causes spillage.
2.
The Motor Solenoid (“M”) Valve should be the only solenoid energized
during the “RAISE” function. Verify that no other Solenoid is energized.
3.
The 4-Way Solenoid Valve may be stuck in the “open” position.
OLD STYLE PUMPS: Verify that the “F” Solenoid Valve is not energized
during the “RAISE” function. Remove the “F” Solenoid Valve Body and clean.
To clean the Valve, remove the Valve Coil from the Valve Cartridge. Using a
paper clip, push on the Plunger inside the Valve Cartridge. It should move
freely approximately 1/8”. Inspect O-Ring and wash the Cartridge in solvent to
remove any foreign substances inside the Cartridge. If Plunger still does not
move freely (approx. 1/8”), then replace the Valve Cartridge.
NEW STYLE PUMPS: Verify that the “C”
Solenoid Valve is not energized during the
“RAISE” function. Remove the “C” Solenoid
Valve Body and clean.
