Lifting and Lowering the Platform
Before the lift table platform is lifted, the lift table must be fixed in place by the two lockable
brakes on the two front swivel castors.
Tip:
If you want to use your lift table for a longer time at the same height position (without adjustment), you
can additionally fix it mechanically with the safety catch (see section
When adjusting the height, make sure that there are no objects between the scissor construction
under the platform and that the safety catches (
13) are unlocked.
Be aware of the risk of crushing hands and fingers, especially when positioning downwards.
Never reach into the scissors during height adjustment!
The height adjustment of the lift table is based on the scissor principle. The hydraulic power is transmitted to the
hydraulic cylinder via the foot pump, whereby foot pump and hydraulic cylinder form a fixed unit.

Before adjusting the height, first secure the lift table against rolling away with the two parking brakes. A foot
pedal for height adjustment is attached to the longitudinal side of the lift table (
Figure 6: Foot pedal UP/DOWN
•
By actuating the foot bar (
A
) downwards, the hydraulic cylinder re-
acts and transfers the force to the scissor unit. The platform moves
upwards gradually with repeated actuation. After approx. 40 actua-
tions the complete lifting height is reached.
•
When the foot bar (
A
) is released, the movement stops and the work-
ing platform remains in this position. In order to adjust the lift table
infinitely and exactly to the desired position, the foot bar (
A
) can be
released at any point.
•
By pressing the foot pedal (
B
) downwards, the working platform is
lowered downwards for the duration of actuation.

Before adjusting the height, first secure the lift table against rolling away with the two parking brakes (

).
Figure 7: Push button unit
•
The height of the table top is adjusted using the removable push-but-
ton unit (
Figure 7) which can be magnetically attached to the sup-
port frame.
•
The platform can be positioned upwards with the
button and
downwards with the
button.
•
The battery hydraulics are controlled according to the dead man's
principle, i.e. the lift table moves in the desired direction as long as
one of the two buttons is pressed. As soon as the button is released,
the table stops and remains in this position.

Accessories for the HS 300 LARGE | AH Battery Unit
•
An optional push-button unit with a 2 m spiral cable (instead of the standard cable) is available (Art.-No.
200.349.00). The push-button unit is additionally equipped with an emergency stop button.
•
As an alternative to the wired push button unit, a radio control for the battery hydraulics is available, which
enables completely wireless operation of the height adjustment (Art.-No. 190.151.00).
