• Put selector switch into position „wheel free jack“
• Lift up vehicle until wheels are free; turn main switch to position „lift“, check if vehicle is fixed
on the automotive lift.
• Lift up vehicle onto desired operation height; turn main switch to position „lift“.
5.6 Lowering the vehicle with wheel free jack
• 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.
• Lower vehicle onto desired operation height or lowest position; turn main switch to position
„lower“.
• Observe complete lowering process.
5.7 Equalization of drive on rails
When the wheel free jack is used for a longer period without reaching the lowest position, an
unequal run can occur. Normally the rails equalize again after the hydraulic oil cooled off. If the
unequal run remains, follow these steps:
• put selector switch into mode „wheel free jack“
• turn main switch to position „lower“ and hold until both rails have reached the lowest position.
• wheel free jack returns to normal function.
