Motors - Otto Bock Skippi Plus Service Manual

6.14 Motors

Each motor of the Skippi Plus has a red brake lever. To unlock the brakes, these have to be
pushed outwards which means that the brakes are released and that the Skippi Plus can
be pushed. This is also indicated on the display when switching on the wheelchair control.
After pressing the two brake levers inwards, the motors are ready for driving again.

Disassembling the motors
CAUTION
Risk of injury. Turn off the power wheelchair prior to performing any work on the motors.
If possible, always remove the battery packs from the drive unit sustainer as well.
For disassembling the motors, first disconnect the motor plugs from the control unit and separate
the drive unit sustainer from the rest of the wheelchair for better accessibility. This makes access
easier. Remove the battery packs from the drive unit sustainer and remove the fender using a
size 3 Allen wrench. Using appropriate materials such as pieces of wood, support the drive unit
sustainer to prevent it from wobbling or tilting to the side. Remove the drive wheel using a size
6 Allen wrench. The motor is attached to the drive unit sustainer with four carriage screws. For
disassembling you need a size 13 open-end wrench.
