26.2.2 Setting the brake
Settings on the brake could be necessary for
the following reasons:
You have changed the tyre or the tyre
pressure.
You have changed the wheel tracking or
the position of the drive wheels.
The brake is pulling unevenly or
insufficiently after extended use.
To adjust the knee lever brake with pull cable
operation, proceed as follows on both sides:
1. Initial situation: Drive wheels mounted on
the product and the knee lever brakes
open.
2. Slightly loosen the M5 fixing screws
(AF 4 mm) which are used to attach the
brake to the brake mounting bar on the
brake mount.

3. Position the open brake so that there is
approx. 3 mm clearance between the
brake bolt and tyre up to a maximum of
4 mm. You can use the adjustment range
provided by the slots on the brake
mounting bar.

approx. 3 mm to maximum 4 mm, with opened

4. Tighten the M5 fixing screws (AF 4 mm)
again to 4 Nm.
5. Then check the correct setting of the
brakes: On a slope (7° gradient) the
product should stand firm with the brake
applied. This will happen if, with the brake
applied, the tyre is depressed or deformed
by approximately 4 mm by the brake bolt
(at prescribed air pressure in the tyres).
When the brake is open, the distance
between the braking bolt and the tyre is
approx. 3 to maximum 4 mm.
