4. Safety regulations
Using automotive lifts for working the regulations of accident EN1493/Aug.98 (CEN/TC
98 „ Automotive lifts”) must be observed.
Especially the following regulations are very important:
• During working with the lift the operating instructions must be followed.
• The laden weight of the lifted vehicle mustn’t be more than 3000 kg for automotive lift
• Only trained personnel over the age of 18 years old are to operate this lift.
• During lifting or lowering the vehicle it must be observed from the operator.
• Position the polymer supports as described of the vehicle manufacturer under the
vehicle.
• If necessary use the ramps.
• It’s not allowed to stay under the lifted or lowered vehicle (except for the operator).
• It’s not allowed to transport passengers on the lift or in the vehicle.
• It’s not allowed to climb onto the lift or onto a lifted vehicle.
• The automotive lift must be checked from an expert after changes in construction or
after repairing carrying pads.
• It’s not allowed to start with operations at the lift before the main switch is switched off.
• It’s not allowed to install the standard-automotive lift in hazardous location.
5. Operating instructions
The Safety Regulations must be observed during working with the automotive lift.
Read the safety regulations in chapter 4 carefully before working with the lift!
5.1 Lifting the vehicle
• Drive vehicle over the lift, longitudinal axes on line of the lift.
If necessary use the ramps for the safe position of the vehicle. If the wheelbase is
too short and the wheels are standing on the ramps, remove the ramps.
• Block the vehicle against rolling, put into gear.
• Position elastomer-supports under the pick-up points of the vehicle as prescribed
by the vehicle-manufacturer.

Operating Instruction and Documentation
Sprinter NT
- 17 -
The vehicle must be positioned on the elastomer supports in a safe way, otherwise
there’s a danger that the vehicle might fall down.
• Check the dangerous places of the lift and be sure that there are no objects or
people in the immediate area of the lift or on the lift
• Switch on the control system; main switch on position ”1” (see pic.1)
• Lift vehicle until the wheels are free. Press button ”lifting”. Check that the vehicle
is safety positioned.
• Lift the vehicle on the working height. Press the button „lifting“ .
• Observe the complete process.

5.2 Lowering the vehicle
• Control the dangerous places of the lift and be sure that there are no objects or
people in the immediate area of the lift or on the lift
• Lower the vehicle to the working height or until the platform reaches the lowest
point; press the button “lowering“
• Observe the complete process.
• If the lift is in the lowest position, remove the polymer-supports.
• Drive the vehicle out of the lift.

5.3 Deaerate the cylinder
• The automotive lift is complete assembled. The connection of the tubes and pipes
are right associated. Only the right power supply , the right oil and the right
portion of the oil and the closeness of the hydraulic parts have to be checked.
If the hydraulic connections be open (prolongation the tubes), air can penetrate in
the tubes.
• If you have an unequal run of the lift. You must check the lift. Check the
coordination of the hoses.
• If necessary a dearing of the cylinder must be carried out at these symptoms:
abruptly lifting from the lowest position, unequal platform with load, not
complete lowering of a platform in the lowest position.
Right dearing:
Checks whether 14 litres are in the oil tank. Oil level = between the upper and the
lower marker.
• Raise the lift – without load – in the highest endposition.
• Open the both equalisation screw A1 and A2 at the hydraulic block.
Remove before the plastic covers.
Pic.4
Position X = the bore hole is for the equalisation screw
• Loose the locknut of the equalisation screws A1 and A2 with a suitable tool.
Unscrew one turn the equalisation screws with a suitable tool.
• Press the button “lifting” approx. 1 sec. The automotive lift can incline.
• Open the vent screw at one cylinder. (easily opening)

Pic.5
Position X = the vent screw at the cylinder
Attention: The lift sinks constantly to below. You can interrupt this process if you
close the vent screw.
• Open the vent screw so long, until only oil comes out of the bore hole. After this
close the screw.
• After this, open the vent screw from the other cylinder and deaerate as described.
Close the vent screw, otherwise a malfunction of the lift may occur.
• Raise the lift in the upper endposition. Press the button „lifting“ . If necessary repeat
the aeration.
• Check the vent screw. These must be closed.
• Lower the lift in the lowest position. Press the button „lowering“and hold it.
• If the lift reached the lowest position, close the equalisation screws (A1 and A2) and
secure it with the locknuts.
• Raise and lower the lift several times without load.
• Check the cylinder lever at the scissor again. (see pic.3)
•To ensure the equalisation of the lift, the chapter 5.4 must be observed
5.4 Equalisation the platforms
• During the normal work of the automotive lift it is almost impossible to get an
unequal run of the platform, by the two independent hydraulic systems.
• If you have an unequal run of the lift. Check the lift.
• If it is sure there is no leak in the hydraulics system and no other external fault, a
compensation may be carried out
• Lower the lift in the lowest position.
• Drive the vehicle from the lift.
• If necessary a compensation must be carried out at these symptoms:

abruptly lifting from the lowest position, unequal platform with load, not
complete lowering of a platform in the lowest position.
Right equalisation:
Assumption: One platform is higher than the other platform.
Measure:
• Lower the lift in the lowest position. Press the button “lowering”.
Equalize the lift without load, otherwise the vehicle can mighty fall down.
• Remove on the right side and the left side the covers of the operating unit.
pic. 2
Position X =
The bore hole in the cover is for the equalisation screw.
• Loose the locknuts (SW17) of the equalisation screws A1 and A2 with a suitable
tool.
• Open slowly the screw A1 and A2. Press the button “lowering” until both
platforms are on the lowest position.
• During this process both platforms get balanced.
Further measure:
• Close the equalisation screw A1 and A2 and safe it with the locknut.
Close after equalisation the screws A1 and A2 and the locknuts. Otherwise a
malfunction of the lift may occur.
• Raise the lift in the upper end position. Press the button “lifting”
• Open the screws A1 and A2.
• Press the button "lowering". Lower the lift approx. 50 mm
