Replacing the lifter actuator

Note
This chapter only deals with the replacement of the lifter actuator.
If you wish to replace the complete lifter module, please proceed as described in Chapter 8.9.3.
Possible methods:
The lifter actuator is very easy to replace if the lifter has been raised completely. Replacement is
slightly more complicated if the lifter is in the lowered position and cannot be run up. The work
required for both methods is described below.
● If you wish to replace the lifter when it is in the raised position, please proceed as described in
Chapter 8.9.5.1.
● If you wish to replace the lifter when it is in the lowered position, please proceed as described in
Chapter 8.9.5.2.
8.9.5.1

Method 1 - Removing the lifter actuator when the lifter is raised

WARNING: Danger of crushing!
The seat is very heavy. Injury hazard to hands if the seat is unintentionally folded down!
● You should seek help from a second person.
● Ensure that the seat is properly secured before you start removing the actuator!
Requirements:
● retaining ring pliers
● oblique pliers
● cable binder
Note
Make a careful note of the seat settings. Mark the fitting positions, alignments, cable routing etc,
and take photos with a digital camera if necessary.
Every change to the seat settings influences the centre of gravity of the mobility device. If the
seat settings are changed, the anti-tip system settings must be checked and readjusted if
necessary as described in Chapter 8.16.5.
● Run the lifter up to the top position if possible.
● If possible, tilt the seat with the tilt module as far as possible to the rear.
● Switch the controller off.
The actuator module for the lifter and the tilt actuators is fitted to the front edge of the seat support.
