The lift does not work

There is no power

Check power and restore if
necessary

The electrical wires are
disconnected

Replace

Fuses are blown

Replace

One of limit switches is faulty.

Check the switch and relevant
connection for proper operation.
Replace, if needed.

The lift does not raise
when the lifting button
is pressed

The motor direction of rotation is
not correct

Interchange the phases on the main
switch

The oil in the hydraulic unit is not
sufficient

Add some hydraulic oil

The lifting button is faulty

Check UP button and connection
for proper operation. Replace, if
needed

The lowering solenoid valve does
not close

Check and clean, if dirty, or replace,
if faulty

The emergency screw of lowering
valve does not close

Retighten the screw

The suction pump filter is dirty

Check and clean if needed

The lift does not lower
when the lowering
button is pressed

The motor does not operate properly
and does not release the mechanical
safeties

Check the motor

The lift goes up instead of going
down
-Because safety air valve is faulty

Replace air valve

-Because the air does not reach the
circuit

Verify the compressor and air hose
ability

-Because electric board is faulty

Replace electric board

The lowering solenoid valve does
not discharge

Verify if it is powered and check
the magneto for damages (replace if
disconnected or burnt)

The lowering solenoid valve is not
operating

Verify if it is powered and check
the magneto for damages (replace if
disconnected or burnt)

The lowering button is faulty

Check the lowering button and
connection for proper operation.
Replace, if needed

The lift does not stop at
the safety height

The safety height limit switch is not
adjusted correctly or it is faulty

Adjust or change the limit switch

The electric board is not operating

Replace electric board

and does not release the mechanical
safeties

Check the motor
