5. Then check the correct setting of the
brakes: On a slope (7° gradient) the prod-
uct should stand firm with the brake ap-
plied. This is the case if, with the brake
applied, the tyre is depressed or deformed
by approximately 4
mm by the brake pin
(at the specified tyre inflation pressure).
When the brake is open, the distance be-
tween the brake pin and the tyre is approx.
3 to maximum 4 mm.
6. The
actuating force
of the brake lever can
be adjusted using the M5 joint screws and
M5 nuts. For this purpose, you need a slot-
ted screwdriver and an open-ended span-
ner (AF 8 mm). The screw is held at the
front with the slotted screwdriver and the
open-ended spanner (AF 8 mm) is used to
tighten or loosen the nut at the rear. An
important point here is that both joint
screws must be tightened equally as this
leads to a long-lasting uniform actuating
force of the brake lever.

force of the brake lever
Note:
The brake pin is usually mounted in the stand-
ard position (see following figure). The assem-
bly of the brake pin in the other possible posi-
tion (see following figure) may be necessary
after the adjustment of the drive wheels.
