23.3.1 Caster wheel fork with screw-on
axle on angle-adjustable caster-
wheel bearing blocks
To remove the caster wheel fork with screw-
on axle, the aluminium cap on the caster wheel
bearing block must first be removed. In order
to release the cap, you can run under the cap
using a commercially available cutter knife and
lift slightly at several points. Then the M12 nut
(AF 19 mm) is loosened using, e.g. an AF
19 mm socket. Now the caster wheel for rotary
axle can be pulled out from under the caster
wheel bearing block.

To assembly the caster fork with screw-on
axle, this is inserted with the caster wheel axle
into the caster wheel bearing block. Then the
M12 nut (AF 19 mm) is tightened again to
3 Nm and secured with thread lock fluid. Then
the aluminium cap is pressed back onto the
caster wheel bearing block.
For the rotary axle to run smoothly, the M12
nut must not be tightened to more than 3 Nm.
In case more sluggishness is desired, this can
be achieved using a higher tightening torque.
23.3.2 Caster wheel fork with screw-on
axle with welded caster wheel
bearing blocks
To remove the caster wheel fork with screw-
on axle, a wrench is used which is included in
the scope of delivery. This wrench is inserted
into the two holes on the nut of the caster
wheel bearing block and turned anti-clockwise,
e.g. using an AF 24 mm fork wrench. The
caster wheel fork needs to be held still. When
the nut has been completely removed, the
caster wheel fork can be pulled out.
