Operating instructions TRAVELER 4all Ergo & 4you Ergo
The length is properly adjusted when the
folding arms are precisely aligned:
Figure 25: Folding arms aligned with correct length
adjustment of the folding mechanism middle section
(bottom view)
Then the new length of the folding mecha-
nism middle section is fixed. For this pur-
pose, insert the cylinder pin in the new po-
sition and push the clamp over the cylinder
pin so that this is located in the middle un-
der the recess of the clamp. Then tighten
the M6 clamp screws to 7 Nm torque again
and secure them with thread lock fluid.
7. With the shorter inlets in the bottom frame
tube, now you can remove the long M6
screws from the threads of the inlets and
reinsert the tube plugs at the ends of the
frame.
8. Then tighten each of the four M6 fixing
screws on the wheel plates to 10 Nm and
check the functioning of the folding
mechanism.
After each change to the tipping point:
the wheel track of the drive wheels must
be checked and readjusted if necessary
(see chapter 22.2).
the caster wheel axle must be readjusted
(see chapter 23.4).
the brakes must be readjusted (see chap-
ter 26).
Extreme settings, such as drive wheels
mounted far to the front is only permitted for
users with advanced wheelchair skills that are
able to exercise an active weight shift to the
front.
In order to minimise the risk of tipping to
the rear, we recommend the use of anti-tipping
supports, even with anti-tipping device set-
tings.
19 Back system
Avoid falling into the seating and back
padding as the risk of an adjustment, falling or
a defect is increased significantly.

19.1.1 Notes on the sitting posture
For a good sitting posture, we recommend
positioning the backrest vertical to the ground,
where possible.
With low backrest with adaptable belt cover
due to a disability, under certain circum-
stances, it may also be a benefit for a good
sitting stability to slightly tilt the backrest to the
front and to slacken the top belt of the back
padding so that the slack in the upper area is
greater (see chapter 19.2).
The adjustment possibility of the backrest an-
gle supports active sitting and ensures for
flexibility of the wheelchair user. An example in
the following:
if the angle of the seat has been changed
(see chapter 18.2), the angle of the back-
rest can be respectively readjusted.
When driving on slopes and when trans-
porting baggage (e.g., backpacks) on the
backrest, the centre of gravity shifts more
to the rear and the risk of tipping in-
creases. Then this can be counteracted by
a respective angle adjustment of the back-
rest to the front.
