the supports are being moved. Place the supports only in the places intended by the vehicle
manufacturer so that the lifted vehicle is actually supported and secured.
Lowering the load:
Only open the relief valve very slowly (turn it anti-clockwise). If the relief valve is open, the load
pick-up is lowered. Lower the vehicle very slowly so that the load and the supports are not shaken.
If the jack has ever been repaired, only raise the vehicle until you can remove the supports. Lower
the vehicle very slowly afterwards.
Slowly turn the lever part anti-clockwise to lower the jack to the lowest position.

MAINTENANCE AND CARE INSTRUCTIONS
The inspection should be carried out each time before the jack is used. Check the device for
leaking hydraulic fluids and damaged and/or lost parts. If any defects are found, the jack must be
inspected immediately. Any jack that is damaged or badly worn or does not work as intended
must be repaired by the Service Department. It is recommended that an authorised repair facility
carry out an inspection annually. Any defective parts, stickers or warning signs should then be
replaced with new ones during the inspection.
Oiling:
All moving joints must be oiled regularly. Oil all the lift arm joints, front wheels and rear roller.
The owner and user is responsible for keeping the warning signs, information and instructions
intact. Replacement warning labels and replacement instructions are available from the
manufacturer.
