BRAKES

The parking brakes are part of the 
most important safety elements of a 
wheelchair. This function is provided 
by toggle joint brake/pressure brakes 
or air pressure independent drum 
brakes.

!

 Attention:

  Please observe the maintenance 

instructions as well as instructions 
in the section < 

General safety in-

structions

 > and < 

Brakes

 > in the 

safety instructions < 

Mechanical 

wheelchairs

 >.

The wheelchair

 

is equipped with two 

brake levers each of the knee-lever 
brake/pressure brake for the user (1).
2 drum brake levers are additionally 
available for the attendant (2).

!

 Attention:

  For optimal braking effect the 

drum brake (3) is to be kept free of 
grease, oil, gunge and dust.

 

– Danger of accidents!

•

  When activating and locking only 

one brake lever on slopes the free 
wheel rolls downhill around the 
braked wheel.

 

– Depending on the inclination of 
the road a sideward tilting has to 
be reckoned with.

•

  If possible propel the wheelchair 

over the handrims. – Perhaps dan-
ger of jamming in the area of the 
brake!
