22.3.1 Caster fork with screwed axle
To
remove the caster fork with screwed
axle
, first the aluminium cap on the caster
wheel bearing block must 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 (socket)) is undone. Now the
caster wheel for rotary axle can be pulled out
from under the caster wheel bearing block.

To
assemble the caster fork with screwed
axle,
this is inserted into the caster wheel
bearing block with the caster wheel for rotary
axle. Then the M12 nut (AF 19 mm) is
tightened hand tight (so that the caster fork can
turn slightly in the caster wheel bearing block)
and secured using screw locking fluid. Then
the aluminium cap is pressed back onto the
caster wheel bearing block.
22.3.2 Caster forks with quick-release axle
The
caster wheel fork with a quick release
axle is removed

between the caster wheel and the inside of the
caster wheel fork. Grasp around the caster fork
and press the locking knob with your thumb.
The caster wheel fork can now be pulled out.

During the
assembly of the caster forks with
quick-release axle,
keep pressing the locking
knob and insert the caster wheel for rotary axle
back into the caster wheel bearing block.
When doing this, special attention should be
paid to ensure that the locking knob springs
out again after attaching the wheel as
otherwise the wheels are not secure. You will
know that if you can see the index groove (Fig.
65).
22.4 Setting the caster wheel for rotary
axle
For good properties for steering and driving
straight ahead of the product, the caster wheel
for rotary axle should be adjusted vertically to
the level ground.
Settings on the caster wheel for rotary axles
could be necessary for the following reasons:
the tipping point and / or sitting heights
have been changed.
the caster wheel axle no longer stands
vertically due to a fall or an impact.
The flattering of the caster wheels should
be reduced.
