Brake Release / Freewheel Operation 
 

In the event of power failure or the need to move 
the powerchair without driving, the 
electromagnetic brakes can be disengaged by 
operating the two yellow levers. One is located 
at the rear right of the powerchair (opposite), and 
the other as indicated on page 3. 

Rear Release 

Lever 

Pull the levers up toward you, this will then 
release the brakes allowing the powerchair to be 
pushed. Simply push the levers in to re-engage 
the brakes. 

 
Caution! Do not attempt to use your powerchair when not in gear. 
Freewheel mode should only be used in an emergency to manoeuvre the 
powerchair due to power failure or to move it WITHOUT AN OCCUPANT. 
Please ensure the brakes are re-applied as soon as possible after dis-
engagement.
