that allows them to "free-wheel". Free-wheeling is accomplished by adjusting the

Free- Wheeling Lever
Warning !
→Never free-wheel your power scooter 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 scooter comes with Electromagnetic Brakes., i.e. an automatic
magnetic disc safety brake which is also known as Fail-Safe brake. The electro-
magnetic Brakes are automatic and work when the power scooter is ON but in a
steady state (i.e. The finger lever control is released to the neutral position), even
when the scooter is on a slope. The Electromagnetic Brakes will also be set
whenever the power scooter is OFF, but the motor levers are in the engaged
(vertical) position.
Note: Please refer to the section titled "To check brakes" in the Maintenance & Repair
section in page 23 to make sure brakes are in good condition.
E. Thermal Protection:
Your power scooter controller is equipped with a safety system called thermal
rollback. A built-in circuit monitors the temperature of the controller and motors.
When they get too warm, power is automatically reduced and you will notice a
reduction in speed of the power scooter. This reduction of speed allows the
electrical components to cool down. Although your power scooter 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.
F. Main Circuit Breaker:
The main circuit breaker reset button is located in the front of the base frame after
removing the shroud.(See Fig 22 )
