Setting Options On Steering Head - Proactive NJ1 Assembly Instructions Manual

Usage instructions Adapter & Adaptation
If the locking heads cannot be turned, this is
usually because the release cord of the folding
mechanism is incorrectly positioned (release
cord in front of the drill holes for the centring
pins) and therefore the locking plate cannot
rest completely on the folding mechanism.

holes for centring pins free

holes for centring pins hidden to the bottom left
If this is not the reason, then the distance of
the locking sliders must be adjusted. To
achieve this the distance measurement via the
nuts on the locking sliders (Metric size 17 mm)
after loosening the M5 threaded pins (Metric
size 2.5 mm) must be adjusted (Fig. 16) so that
the locking heads can be turned and the ten-
sion on the clamp levers is ideal (i.e. when the
clamp levers are tight there can be no play
between the locking sliders and folding arms
and there must always be a noticeable resis-
tance when tightening the clamp levers). Even
tension must be ensured on all 4 locking slid-
ers. Once the distance measurement and ten-
sion has been set, tighten the nuts by hand at
20 Nm and the threaded pins at 4 Nm and
secure the threaded pins with screw locking
fluid.

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 finally loosening the two M6 clamp
screws (Metric size 5 mm), the steering head
can be tilted by 25°. When the right position
has been found, the two clamp screws must be
tightened up again with tightening torque of
7 Nm and secured with screw locking fluid. The
associated nuts (Metric size 17 mm) must be
tightened for this.
