Adjusting The Caster Wheel Axles (When Fitted In Angle-Adjustable Caster-Wheel Bearing Blocks) - ProActiv SPEEDY F4 Usage Instructions

22.4 Adjusting the caster wheel axles
(when fitted in angle-adjustable
caster-wheel bearing blocks)
The following instructions are intended
for and may only be carried out by a rehabilita-
tion specialist dealer or PRO ACTIV
To ensure that the product has good properties
when steering and driving straight ahead, the
caster wheel axle should be adjusted to be
vertical to the level ground.
Adjustments on the caster wheel axles can be
required for the following reasons:

The tipping point and/or seat heights have
been changed.

The caster wheel axles are no longer verti-
cal due to a fall or an impact.

The flattering of the caster wheels should
be reduced.
To adjust the caster wheel axle, the product
should be placed on a level surface and the
wheel track of the drive wheels must have
already been adjusted (see chapter 21.2).
Now check to see if the caster wheel axles
are perpendicular to the level ground. For this
purpose, place an angle with height adjustable
slider on the front edge of the caster wheel
bearing blocks. The slider should be aligned at
the middle of the caster wheel bearing block.
Information:
If the front edges of the caster wheel bearing
blocks are perpendicular to the level ground,
the caster fork rotary axles are as well.
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.

Tool recommendation:
The angle with slider can be ordered from
PRO ACTIV (order number: 8000 901 000).
If the front edges of the caster wheel bearing
blocks are not standing vertical to the level
ground, the settings must be adjusted. First,
adjust the right caster wheel bearing block,
then the left one, and finally check the right
side again. To do this, proceed as follows:
1. Loosen the M5 stud bolt (AF 2.5 mm).

2. Undo the M6 fixing screw (AF 5 mm)
slightly on the frame inner side.
