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 forks with quick-release axle
The caster wheel fork with a quick-release
axle is removed by pressing the locking knob
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 other-
wise the wheels are not properly secured. You
will know this if you can see the index groove
(Fig. 71).
23.4 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.
To adjust the caster wheels for rotary axles,
the product should be standing on a level sur-
face and the wheel track of the drive wheels
must have already been set (chapter 22.2).
Now check if the caster wheels for rotary axles
are standing vertically to the level ground. For
this purpose, place an angle with height ad-
justable slider on the front edge of the caster
wheel bearing blocks. The slider should be
aligned at the middle of the caster wheel bear-
ing block.
If the front edge of the caster wheel bear-
ing block is standing vertically to the level
ground then the caster wheels for rotary axles
is also doing this.
Observe that the front edges of the caster
wheel bearing blocks are slightly rounded.
Thus, the distance above and below between
the slider of the angle and the front edge of the
caster wheel bearing blocks must be the same
size.
