7.3.3 Adjusting the seat angle
CAUTION
Incorrect handling of the seat tilt
Tipping over, falling out of the seating shell/seat due to errors in handling the product
►Before operating the seat tilt (seat angle adjustment), practise without the seated user.
►Only operate the seat tilt on a level, firm surface.
►Always activate the anti-tipper before operating the seat tilt (inclination of the seat).
►Before negotiating slopes or crossing obstacles, the seat tilt must be lowered (horizontal neutral position of
the seat). It is advisable to incline the seat tilt slightly to the rear when driving downhill.
►Drive only on slopes where the holding forces remain manageable.
►Never use the release lever to operate the seat tilt (seat angle adjustment) in an uncontrolled manner.
►When activating the release lever, always secure the user against falling out to the front or rear. To do so,
keep a firm grip on the push handle while activating the locking pedal until the adjustment system audibly
engages on both sides.
►Do not reach into the adjustment mechanism when using the seat tilt.
►Avoid getting caught in the Bowden cable as this can result in release of the seat tilt.
The seat can be moved back continuously up to an angle of 35° (see fig.13):
1) Hold the push handles/push bar firmly.
2) Activate and hold the release lever (see fig.14, item 1).
