LIFTGATE WILL NOT LIFT RATED CAPACITY

1.

Verify that the Battery shows 12 volts or better under load from pump

motor. 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 the

Platform on the ground, remove the
Breather Plug or Vent Line from the
Vent Port of the Cylinder. Raise the
Platform. If hydraulic fluid streams from
the Vent Port, the Piston Seals are
worn. Replace the Seals.

4.

With Platform on the ground, remove

the pressure hose and fitting from the
Pump and replace 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)

5.

If Pump cannot produce 2800-3000 PSI with a minimum of 12 Volts

available, the Pump is worn and needs to be replaced.
