Setting options on steering head

The angle-adjustable steering head can influ-
ence various parameters, such as the lifting
distance of the wheelchair steering wheels on
the adapted product, the distance between the
product wheel and wheelchair foot bed, or the
distance of the product's operating elements to
the user's body.
To adjust the angle of the steering head, the
four M6 adjustment screws (Metric size 3 mm)
must first be released on the top and bottom
on the steering head.

After then loosening the two M6 clamp screws
(Metric size 5 mm) the steering head can be
tilted by 25° on the side of the steering head
connection. When adjusting the angle of the
steering head, you must ensure that the wheel
can run freely (horizontal dimension between
M6 adjustment
screws
the extended steering axis) between 60 mm
and 120 mm.

When the right position has been found, the
two clamp screws must be tightened up again
with a tightening torque of 7 Nm and secured
with screw locking fluid. The associated nuts
(Metric size 17 mm) must be tightened for this.

Then, the M6 setting screws (Metric size
3 mm) must be turned again towards the steer-
ing head connection so that they rest on the
steering head connection. The M6 setting
screws are used so that the steering head can
no longer turn after the setting has been made.
