marily for use indoors and on firm lev-
el surfaces.
The crossing of uneven surfaces,
grooves or edges, etc. can lead to a
full-braking. – Accident risk, user
could fall out of the wheelchair.
FRONT SEAT-HEIGHT
The adjustment should be car-
ried out by the specialist
dealer!
The seat tilt is infinitely variable by con-
stant chassis geometry.
HANDRIM
All handrims [9] are designed for a dis-
tance to the driving wheel [8] of 15 mm
(standard setting) and 25 mm (Fig.34).
Replacement of handrims or modifica-
tion of handrim distances should always
be carried out by your authorized spe-
cialist workshop.
Please observe the chapter
“Handrims” in your brochure “Safety
Notes -– Mechanical Wheelchairs”!
HAND AND SPOKE
GUARD
The hand and spoke guard prevents inju-
ries to the hands occurring by jamming
in the turning spokes of the wheels, as
well as damage to the spokes.
Handling:
Tools 2x slot screw drivers
– Dismantle clamping screws (A,
Fig.35) of the disc to be replaced.
– Replace defective disc.
– Position new disc (see note).
– Assemble clamping screws (A).
Note:
Gently press the hand and spoke
guard discs through the appropriate
grip wheels.
The notches on the circumference of
the discs lie above the handrim brack-
ets!
All three bores of the discs should be
positioned between two crossing
spokes!
Note:
If toe-in adjustment equipment is not
available, use two items of identical
height (e.g. bottles as in Fig.33) in or-
der to measure the spacings at the same
height.
– Readjust on each side for a ¼ of the
difference between the front and
rear measured drive wheel spacing.
• Measure the front spacing from drive
wheel to frame tube (Fig.32).
• Rotate the axle mount adapter in the
appropriate direction to readjust for
a ¼ of the difference on both sides.
• Compare the new spacing on both
sides.
Note:
The toe-in of both sides must be identi-
cal. Different toe-in settings will cause
your wheelchair to roll to the left or right
of a straight line.
– Tighten the adjustment screw (A,
Fig.31) of the tube clamp.
