A. Free-Wheeling:
Because the motors are designed to engage the electromagnetic brakes
when the vehicle is not in use or when the power is OFF, they also have a
manual feature that allows them to “free-wheel”. Free-wheeling is
accomplished by turning the free-wheeling levers to the freewheeling
position.(See Fig 24)
Warning !
→Never free-wheel your power wheelchair on a slope.
→Never free-wheel the motors while operating your vehicle.
→Always remember to engage the motors before turning the power back
ON.
(Fig 24)
B. Electromagnetic Brakes:
Your power wheelchair comes with an Electromagnetic Brakes., i.e. an
automatic
magnetic disc safety brake which is also known as Fail-Safe brake.
The Electromagnetic Brakes are automatic and work when the power
wheelchair is ON but in a steady state (i.e. Joystick is released to the
neutral position), even when the chair is on a slope. The Electromagnetic
Brakes will also be set when-
ever the power wheelchair is OFF, but the motor levers are in the engaged
(vertical) position.
Note
: Please refer to the section titled to check brake in the Maintenance &
Repair section in page 21 to make sure brakes are in good condition.
C. Thermal Protection:
Your power wheelchair controller is equipped with a safety system called
thermal
rollback. A built-in circuit monitors the temperature of the controller and
motors, the controller reduces the motor voltage and speed of the power
