Attention:
The skater wheels code 446 are
primarily for use indoors and on firm
level 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.
HANDRIM
All handrims are designed for a dis-
tance to the driving wheel of 15 mm
(standard setting) and 25 mm (Fig.37).
Replacement of handrims or modifica-
tion of handrim distances should always
be carried out by your authorized spe-
cialist workshop.

Remark:
Please observe the section
“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.37) of the disc to be replaced.
– Replace defective disc.
– Position new disc (see note).
– Assemble clamping screws (A).
+
Remark:
Gently press the hand and spoke
guard discs through the appropri-
ate grip wheels.
The notches on the circumference
of the discs lie above the handrim
brackets!
All three bores of the discs should
be positioned between two cross-
ing spokes!
If toe-in adjustment equipment is not
available, use two items of identical
height (e.g. bottles as in Fig.36) in order
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.35).
• 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.
+
Remark:
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 (C,
Fig.32) of the tube clamp.
