5.1.1 UP PUSH BUTTON
If pressed, it activates the electric motor and
mechanisms that lift the carriage.
5.1.2 LOWERING LEVER
By pressing down the lowering lever, it activates the
pressure relief valve. The oil from oil cylinder returns
to the oil tank. The carriage lowers.
5.2 OPERATING SEQUENCE
Position the lift arms in the hold points prescribed for
the vehicle, adjusting the disks to the same height.
Each time the carriages are brought down to the
ground, check the position of the disks under the
chassis of the vehicle before raising the carriages
again.
5.2.1 LIFTING
Press the up push button until reaching the required
height. As the carriages are raised, the safety
wedges are inserted automatically into each of the
iron pad under the carriage. Regarding lift limits and
safety devices,
see pages 6, 7 “RISKS WHILE THE
VEHICLE IS BEING RAISED”
.
5.2.2 PARKING
Once the required height has been reached, keep
pressing the lowering lever on the power pack. The
movement is stopped automatically when the safety
wedge rests on the level of the first slot that they
come in contact with while the carriages are coming
down.
5.2.3 LOWERING
Before lowering the carriages, the safety wedges
must be disconnected. Press the up button to lift the
carriages about 3 cm. Then pull the lock release
lever to release the safety wedges.
(Fig. 40)
Then
hold the lowering lever on the power pack to lower
the carriages. Lowering speed is regulated by the
“flow regulating valve” in the pump. Lowering stops
when the hydraulic cylinders are completely
unloaded. When the carriages are totally lowered,
the automatic arm-blocking device opens and lets
the carriages rotate.
