PLATFORM WILL NOT RAISE

1. Verify that power is being supplied to the Solenoid Terminal �A�. Rechargethe battery if less than 12 volts.

2. Fill Reservoir to within 1/2� below the top with the recommended hydraulicfluid.

3. Touch a jumper wire to terminals �A� & �C�. If motor runs, check Switch,Switch connections, and White wire. Correct the connections or replacethe Switch.

4. Touch heavy jumper cables to terminals �A� & �B�.a. If motor runs, replace the motor solenoid.b. If motor does not run, repair or replace the pump motor.

5. Check for structural damage. Replace worn parts.

6. Check filter in the pump Reservoir. Replace if necessary.

7. Check for a broken motor-to-pump coupler. Replace if necessary. A wornpump is extremely noisy, and needs replacement.

8. If equipped with a Low Voltage Thermal Switch (LVTS), system could shutdown if the motor temperature or battery voltage level reach an unaccept-able level. Read decal P/N 264776 located near the switch to determinewhat steps need to be taken to correct the problem.

PLATFORM WILL NOT LOWER

1. Verify that power is being supplied tothe Solenoid Terminal �A� (Ref. Fig. 1).Recharge the battery if less than 12volts.

2. Check for structural damage or lack oflubrication. Replace worn parts.

3. Check Solenoid Valve for power by holding a screwdriver approximately1/4� from the top nut of the Solenoid. Energize the unit. (See Fig. 2). Agood solenoid will draw the screwdriver to the nut by a magnetic force.The Coil can be replaced by removing the Nut and Wires.

4. Check the Valve Stem by removing the Coil Assembly, (Item 1, Fig. 3).Unscrew the Valve Stem, (Item 2, Fig. 3), from the Pump. Push on theplunger that is located inside the Valve Stem by inserting a paper clip inthe end. If the Plunger does not move freely approximately 1/8�, replacethe Valve Stem.

5. If equipped with a Low Voltage Thermal Switch (LVTS), system couldshut down if the motor temperature or battery voltage level reach anunacceptable level. Read decal P/N 264776 located near the switch todetermine what steps need to be taken to correct the problem.

PLATFORM RAISES BUT LEAKS DOWN

1. Check Solenoid Valves for electrical shorts byholding a screwdriver approximately 1/4� fromthe top nut of the Solenoid. (See Fig. 1). Thesolenoid should not draw the screwdriver tothe nut with a magnetic force, unless thetoggle switch is actuated. The Coil can bereplaced by removing the Nut and Wires.

2. Check the Valve Stem by removing theCoil Assembly, (Item 1, Fig. 2). Unscrewthe Valve Stem, (Item 2, Fig. 2), from thePump. Push on the plunger that is locatedinside the Valve Stem by inserting a paperclip in the end. If the Plunger does notmove freely approximately 1/8�, replacethe Valve Stem.

3. Check the Hydraulic Cylinder. With thePlatform on the ground, remove theBreather Plug or Vent Line from the VentPort of the Cylinder. Raise the Platform tobe level with the bed. If hydraulic fluidstreams from the Vent Port, the PistonSeals are worn. Replace the Seals.(See Fig. 3).

PLATFORM RAISES PARTIALLY AND STOPS

1. Lower the opened Platform to the ground. Fill the Reservoir to within 1�from the top with the recommended Hydraulic Fluid.

2. Verify that the Battery shows 12 volts or better under load from pumpmotor. The use of a voltage load tester is recommended.

3. Check for Structural damage, or lack of lubrication. Replace worn parts.

4. Check Filter in the Pump Reservoir. Replace if necessary.

5. Check for a broken motor-to-pump coupler. Replace if necessary. A wornpump is extremely noisy, and needs replacement.

6. If equipped with a Low Voltage Thermal Switch (LVTS), system couldshut down if the motor temperature or battery voltage level reach anunacceptable level. Read decal P/N 264776 located near the switch todetermine what steps need to be taken to correct the problem.

1. Verify that the Battery shows 12 volts or better under load from pumpmotor. The use of a voltage load tester is recommended.

2. Check for Structural damage or lack of lubrication.Replace worn parts.

3. Check the Hydraulic Cylinder. With thePlatform on the ground, remove theBreather Plug or Vent Line from theVent Port of the Cylinder. Raise thePlatform. If hydraulic fluid streams fromthe Vent Port, the Piston Seals areworn. Replace the Seals.

4. With Platform on the ground, removethe pressure hose and fitting from thePump and replace it with a 0-3000 PSI Pressure Gauge. Hold theswitch in the �UP� position. Adjust the Relief Valve on the side of thePump until the gauge shows 2800 to 3000 PSI . (See Fig. 2)

5. If Pump cannot produce 2800-3000 PSI with a minimum of 12 Voltsavailable, the Pump is worn and needs to be replaced.

PLATFORM RAISES SLOWLY

1. Verify that power is being supplied toTerminal �A�. Recharge the battery if lessthan 12 Volts registers on the VoltageTester. (See Fig. 1)

2. Lower the opened Platform to the ground.Fill the Pump Reservoir to within 1� fromthe top with the recommended hydraulicfluid.

3. Verify the Pump Motor is grounded to thevehicle frame.

4. Check for leaking hoses and fittings.Tighten or replace as required.

5. Check for structural damage or lack oflubrication. Replace worn parts.

6. Check the Filter in the Pump Reservoir. Replace if necessary.

7. With Platform on the ground, remove the pressure hose and fitting from the Pump andreplace it with a 0-3000 PSI Pressure Gauge. Hold the switch in the �UP� position.Adjust the Relief Valve on the side of the Pump until the gauge shows 2800 to 3000 PSI(See Fig. 2).

8. With the Platform on the ground, remove breather plug or vent line from vent port ofcylinder. Raise the Platform to bed level. If hydraulic fluid streams from the Vent Port,

LIQUID SEALANT APPLICATION

Clean all threads with a soft brush and a suitable cleaning solvent.

Dry threads thoroughly with compressed air or shop towel.

Apply the Liquid Sealant (Compound PLS 2), to the external threads ofthe Male Connector.

Assemble the fitting and torque it to the prescribed value.

Check for leakage. If leakage exists, remove the fitting and return toStep # 1.

If fitting is loosened or removed, return to Step # 1.
