38 OPI-POWER LIFT HDL 15000 - HDL 18000-V1.0-EN
• Switch on controls. Turn the main switch to posi-
tion “1”
• Lift the vehicle until the wheels are off the ground.
Push the “Lift” button.
• If the wheels are not blocked, interrupt the lifting
process and check for proper seating of the car-
rier plate.
Ensure secure vehicle placement on
the carrier plate, otherwise there is a
danger of the vehicle dropping.
• Raise the vehicle to the desired working height.
• Always observe the complete lifting process.

5.2 Lowering the vehicle
• Inspect the hazardous area. No person or object
may stand in the working area of the lift, or on the
lift.
• Place the vehicle to the desired work position or
lower it to the lowest position.
Push the “Lower” button. The lift raises briefly (un -
locking the safety cylinder) before the actual low-
ering process starts.
• Before reaching the lowest position the lift stops
the lowering process for safety reasons (CE
stop).
After a recheck of the hazardous area, push the
“Lower” button again. During lowering to the low-
est position an acoustic warning signal can be
heard.
• The lowering process must be continuously ob-
served.
• Once the lifting arms have reached the detect-
able lowest position, swivel the lifting arms out-
wards. For this, push the “unlock” button.
• The vehicle can be driven off the lift.
5.3 Travel measurement
• To measure the travel of the threaded spindle, a
Hall sensor is attached to the hydraulic cylinders
which counts the external ring in magnetised in -
crements. These increments are transmitted and
compared on the computer control system (axis
controller). An uneven lift rail is balanced to the
same height during a lifting or lowering move-
ment. The current height position of the lift can be
read off from the display.
• The computer control system monitors the entire
process of the lift during “lifting” and “lowering”.
• The lift lowers during normal operation at 0.05 me-
tres per second (HDL 6500: 0.039 meter per sec-
ond)
If the speed increases, e.g. due to a defect in
the hydraulic system, the computer control sys-
tem detects this problem and removes hydraulic
supply to the unlocking cylinders. The interactive
safety system is activated and the lift remains in
place.
5.4 Manual equalization of the lifting rails
Access to the DIP switch may solely
be done by a trained and authorised
specialist and only with the main
switch turned off.
Once the Computer Control System detects a
height difference of approx. 40 mm from one lift rail
to another, the lift automatically sets down.
