The motor runs but the lift does not rise
The lift is overloaded
Check the vehicle weight and/or the balance of the
vehicle on the lift
The motor is being operated on very low voltage Provide the correct power supply to the motor
Deposits in the parachute valve
Clean the lowering valve
The pump is sucking in air Tighten the coupling on the intake line.
The intake fitting has separated from the pump Replace the fittings
The oil level is low
Fill the tank to the correct level with ISOVG32 hy-
draulic oil or Dexron III ATF
The release valve is incorrectly set Replace the release valve
The lowering valve is open Repair/replace the lowering valve
The lift lowers slowly
Deposits in the check valve set Clean the check valve
Deposits in the lowering valve set Clean the lowering valve
There are oil leaks Repair the external leak
The lift rises slowly or oil leaks from the inlet
deaerator cap
Air has mixed with the oil Change oil, Dexron II ATF or ISOVG32 hydraulic oil
Air is being taken in with the oil Tighten all couplings
The oil return line is loose Repair the external leak
The lift rises unevenly
The synchronisation cables are offset
Adjust the synchronisation cables to correct the
tension
The lift is installed on an uneven foundation
Adjust the lift so that the columns are at the same
height, (use shims no higher than 13 mm)
The anchoring bolt is not secure
The holes are too large
Move the lift and use a new drill to drill holes.
The correct anchoring methods and the minimum
installation requirements are described in the
installation instructions
The depth of the foundation or the concrete
quality is inadequate
Lay a new foundation slab in the lift zone as per
the requirements
The lift does not rise completely or the lifting
process is erratic.
Air in hydraulic lines or cylinders
Start the system and raise and lower the slider
block several times. Lower the lift to the bottom
position and refill the drive unit as in step 2
The oil level is low
Lower the lift to the bottom position. Fill the tank
with ISO VG32 hydraulic oil or Dexron III ATF to
at least the MIN mark
The locking latches do not engage The latch mechanism shafts are oxidised Contact service staff for support
