• The distance between the pivot bolt and the outer tyre
cover at maximum open brake mechanism/device has
to be x =15 mm at the narrowest part.
• To adjust the distance you have to remove the two
hexagon socket screws at the brake mounting
(underside/bottom)Picture 18
• Then you pull the brake system along the mounting in
the correct position.
• The pivot bolt must be horizontal e.g. parallel to the
underground
• Finally you have to tighten up again both hexagon
socket screws.
• Make sure that the brake snaps in when you use the
brake lever and that it does not snap back.
The brake adjustment should be carried out by
trained experts. However if you have enough
experience you can do the job yourself. But
consider that wrongly adjusted brakes can have
life-threatening consequences.
In order to ensure optimal brake functioning
pneumatic wheels should have a pressure of
300-400 k Pa (3-4 bars). If the air pressure in
the tyres is not according to the regulations then
there is a danger of brake function loss.
