Vehicle positioning

DANGER – Risk of incorrect vehicle positioning
Risk of (fatal) injury due to the vehicle falling
or tipping up during lifting, when working on
the vehicle and on lowering.
¶
Position the vehicle exactly as described.
1. Make sure the support arms are fully lowered and
swivelled to the maximum clear width.
2. Drive the vehicle into position between the columns
such that it is straight and centered.
!
Heed the direction of travel. The operating unit must
be on the right lifting column when viewed in the
direction of travel.
3. Drive the vehicle forwards until the center of gravity
of the vehicle is on a level with the columns.
i
On many vehicles the center of gravity is roughly on
a level with the front door hinges.
4. Carefully open the door and get out of the vehicle.
!
Take care not to bang the vehicle door against the
column.
5. Check the jacking points specified by the vehicle
manufacturer for stability and corrosion.
6. Swivel the support arms under the vehicle and posi-
tion the mounts under the four jacking points.
7. Turn the mounts until they are in full contact with
the jacking points.
!
Never turn the mounts beyond the stop. The remai-
ning thread length would not guarantee firm sup-
port.
i
Use the spacer sleeves provided if the height adjust-
ment of the mounts is not sufficient.
!
Only use the spacer sleeves specified by Bosch.
Never fit wooden or concrete blocks.

Vehicle lifting

DANGER – Risk of vehicle falling or tilting!
Risk of (fatal) injury on lifting (or raising) the
support arms.
¶
Make sure there is no-one in the vehicle or
in the area of the lifting platform.
¶
Keep away from the support arms and the
vehicle.
¶
Observe the support arms, the jacking
points and the vehicle.
1. Pull the locking handle and press the control lever
upwards (o) for approx. 1 second.
 The support arms move upwards for as long as
the control lever is being pressed upwards.
2. Stop and check locking of the support arms. If ne-
cessary, move the support arm slightly to engage it.
3. Raise the vehicle until the tires are no longer in con-
tact with the ground. Then stop.
!
If the front and rear axles are not raised evenly, the
vehicle is incorrectly positioned. In this case: Lower
the support arms, re-position the vehicle and repeat
the lifting operation.
4. Check that the mounts are in firm contact with the
jacking points.
!
If the vehicle is not stable: Lower the support arms, re-
position the vehicle and repeat the lifting operation.
5. Continue raising the vehicle after ensuring its stability.
6. Raise as far as the required height or to the upper
end position and then release the control lever.
"
The lifting platform is raised and locked.
