5.22 Motor Brakes
5.22.1 Electro-magnetic brakes operate automatically when the
controller joystick is central with a delay of approximately 1/2
second. The controller automatically provides progressive
deceleration before the electro-magnetic brakes come into
operation.
5.22.2 To check the brakes are operating correctly: switch the
wheelchair on and move the joystick in any direction.The brakes
should disengage. Repeat this check in all four directions
ensuring the brakes engage each time the joystick is released to
its central position. An audible click from each motor indicates
the brakes are working.
5.23 Parking Brakes - Hand Operated
5.23.1 The parking brakes operate directly on to the tyre providing
positive locking of the drive wheels. They should only be used
when the motors are disengaged. The brake levers are situated
on the rear frame strut and can easily be operated by both user
and attendant. Pull up for on & down for off. (ensure that the
tyres are always inflated to the recommended pressure).
5.23.2 Care Points Avoid finger traps. Do not touch the drive wheels or
front casters.
5.23.3 Prevent children and others from putting their hands near the
drive wheels or front casters.
5.23.4 Never use the wheelchair with the drive wheels disengaged
unless there is someone in attendance as the motor brake will
not operate.
