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 free-wheeling position.(See Fig 18)
(Fig 18)
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.
D.
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 wheelchairs
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 17 to make sure brakes are in good condition.
E.
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 wheelchair. The
reduction of the speed allows the electrical components to cool down. Although
your power wheelchair will resume its normal speed when the temperature returns
to a safe level, we recommend that you turn the power off and wait for 5 minutes
before restarting to allow the components to cool down if you find that you have
lost speed suddenly.
