MANUAL LOWERING
If the car lift cannot perform lowering operations because of power supply interruption, faulty hydraulic valves
or electric trouble in the system, the lift can be lowered manually. For manual lowering operation (emergency),
perform the following:
• Make sure there are no obstacles blocking the lowering phase; remember that the car lift may not be lifted
again to remove possible obstacles.
• Disconnect main power supply.
Note: Manual lowering (emergency) operations should be preformed by authorized personnel specially trained
for operating the car lift only.
• See page 12 for hand pump operating instructions before using hand pump.
• Hook up hand pump to hand pump port shown in fig.5.
• Pump hand pump enough to raise lift enough to release locks.
• For operational air perform step 1 and with manual locks perform step 2 for lock release.
1. Release lock by pressing lock button found on control panel.
2. Manually remove locking bar.
• Press electric soleniod with screw driver to release hydraulic pressure and lower lift. See location of solenoid
