4. Safety regulations
Using automotive lifts for working the Regulations of Accident Prevention (VBG1:
General Regulations in Germany, VBG14: Automotive lifts) must be observed.
Especially the following regulations are very important
•The laden weight of the lifted vehicle mustn’t be more than 3500 kg, the maximum
load sharing is 2:1, in drive-on direction or against drive-on direction
•While the automotive lift is working the operating instructions must be followed
•Only trained personnel over the age of 18 years od are to operate this lift
• While the vehicle is lifted or lowered it must be observed from the operator.
• Do not transport passengers on the lift or in the vehicle
• Do not climb onto the lift during lifting or lowering or onto a lifted vehicle
• The Automotive Lift must be checked from an expert after changes in construction
do not start with operations at the lift before the main switch is switched off
•Do not install the standard-automotive lift in hazardous location or in washing halls
•Keep key to a safe place during normal operation of the lift. The key must not be
in the lock.
5. Operating instructions
The Safety Regulations must be observed during working with the automotive
lift. Read the safety regulations in capter 4 carefully before working with the
lift!
The operating elements are shown in picture 1.
Lifting the vehicle with the automotive lift
•Drive vehicle on the lift, longitudinal directon and transverse direction in centre
Each wheel must stand completely on the rail otherwise the vehicle might
fall down
• Safe the vehicle against rolling away, switch into gear
•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
• Turn the key switch on position “ “
• Lift the vehicle on the working height. Observe the complete process
Lowering the vehicle with the automotive lift
•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.

• Turn the key switch on position “ “.
• The lift raised a little bit before the lowering starts
• Lower the lift on the working height . Observe the complete process.
Comment!
If the main lift is in a height of 200 mm over the floor the electric switched off
automatically. In this case turn the key in position “0“ and after in position “ “
again. You hear an accoustic warn signal until the lift is in the lowest position.
•Drive the vehicle from the lift if its in the lowest position.
Lowering into the ratchet strip
•Activate button „lowering in ratchet“ (see pic.1).
•Push button as long as all four ratchets are engaged and the lift does not move any
more.
Lifting out of the ratchet strip
•Turn the key on position “ “ until the ratchets are free.
Driving on an obstacle
If the lift is running onto an obstacle during the lowering, it stops automatically. In this
case push bypass switch on the operating column and turn the key on position “ “
simultaneous until the obstacle can be removed.
6. Troubleshooting
If the lift does not work properly, the reason for this might be quite simple. Please
check the lift for the potential reasons mentioned on the following pages. If the cause
of trouble cannot be found, please call the technical service.

Repairs at the lift’s security devices as well as repairs and examinations of the
electrical fittings may only be performed by specialists.
Problem: Motor does not start!
Potential causes • The main switch is not switched on
of trouble: • Fuse is defective: replace fuse
• Feed line is cut
• power failure
• the rope is torn and the limit switch is pressed
(call the technical service)
Problem: The Lift does not lowered, but lifting !
Potential causes • The coil of the magnetic valve is defective
of trouble: • The ratchets are engaged, move up the lift before lowering
Problem: The Lift does not lifting, but lowering !
Potential causes • the top limit switch is pressed
of trouble • the direction of the motor is wrong
Emergency lowering in case of power failure or defective valves
In case of power failure or defective valves the hydraulic valve for lowering of the lift,
there is the possibility to lower the lift by opening the hydraulic valve manually, so the car
can be driven off.
In case of power failure emergency lowering can only be performed when the
ratchets are not engaged (when the ratchets can be pulled back manually). In
case of defective valve the lift can be lifted a little bit by turning key to lifting
position (to right side) So there is the possibility of pulling back the ratchets
manually.
The emergency lowering must only be performed by persons instructed to use
the lift. Please refer to the regulation ”Lowering”.
• Pull back the ratchet manually and lay a suitable support (wedge, cloth) between the
ratchet-strip and the ratchet or fix the pulled-back ratchet with the help of a wire. So
the ratchet tooth of the ratchet can not engage in ratchet-strip any more. This step
should be taken at all of the four columns.
• Loosen emergency lowering screw (set screw) for one turn to start the lowering
(the emengency lowering screw is on the side of the rail);

with a hexagon socket screw key . (see pic.)
•Fasten emergency lowering screw and safe it with the red coloured security nut
when the lift is at lowest position.
After finishing the emergency lowering, the emergency lowering screw
and the security nut (coloured red) must be brought into the position they
have had before. Otherwise a malfunction of the lift can occur.
• Remove support or wire of the ratchets.
To guarantee the safe running of the lift the supports must be removed
from the ratchet to bring the ratchet in its normal function.
• Drive the vehicle from the lift.
7. Maintenance
Aregular service has to be performed every three months by the lift’ s operator accor-
ding to the following schedule. If the lift is in continuous operation or dirty environ-
ment, the maintenance rate has to be increased.
During daily operation the lift has to be watched carefully for its correct function. In
case of any malfunction or leakage the technical service has to be informed..
Maintenance schedule for the lift
• Clean piston rods of hydraulic cylinder from sand and dirt
• Clean and lubricate running pieces of the lift (hinge bolts, sliding pieces, sliding
surfaces) (multipurpose lipid)
• Grease all the lubricating nipples (multipurpose lipid)
• Check ratchets if they engage smoothly and grease striking surfaces.
