2.5 General safety instructions
Before each use be sure to check:
• frame, back tubes, attachments and accessories for visible damage, bends, cracks or missing/loose scews,
• wheels/quick release axles for rm t,
• sucient tire pressure, tire tread,
• functionality of the brakes,
• rm t of the angle adjustment elements/ eccentric clamps,
• rm t of the seat plate/ the back/ the foot plate,
• functionality of the anti-tipper/ seat and back straps,
• if all previously disassembled parts are re-inserted or rmly locked.
There is a risk of injuries (e. g. such as bruising) on all rotating or folding parts, including
adjustments, repairs and transport.
All wheelchair parts are to be handled with care. Do not throw or drop removable parts.
Before repairs or adjustments are made, clean/didinfect the wheelchair and secure it from
tipping over and/or falling down.
Only use original spare parts.
Safety nuts may only be used once. Lossened safety nuts must be replaced by new ones.
Only the regular maintenance of all safety-relevant parts on the wheelchair by a qualied
rehab workshop protects against damage and maintains our manufacturer's warranty.
Combination with products from other manufacturers
The wheelchair may only be combined with the electrical auxiliary drives apporved by the
manufacturer. Restrictions or adaptations as well as the attachment itself must be done by the
supplier of the additional system or the authorized specialist dealer.
Please check the conditions with the manufacturerer of the audiliary drives.
In combination of wheelchair and electric auxiliary drive, certain strains can occur which
can lead to damage to the wheelchair. Slowly approach obstacles and carefully overcome
them so that little force is applied to the caster, driving wheel and wheelchair as a whole.

3.1 Assembly Group Wheels
Version since 02/2017
The wheelchair is delivered with the appropriate toe-in, depending on the wheel camber adjust-
ment and attachment of the steering and pushing aid. When changing the camber or retrotting
the steering or pushing aid, it may be necessary that the toe must be changed.
(1) In order to avoid the so-called "eraser
eect", we generally assemble the matching
track compensation (A) at the factory. If the
camber is subsequently changed, it may be
necessary to replace the track compensation
adapter (A) with a suitable one (spare part).
To change toe-in:
• Remove drive wheels,
• and remove screw connection (B+C).
•
• Depending on the mounting variant
and camber, please observe the instructions on the following pages.
• After changing the toe settings:
• replace the screws (B+C) and tighten the screws (B).
• Check / correct the distance between the drive wheel and the side part or clothing protection by attaching the drive wheel.
The tires of the wheel must be at least 10 mm
away from the side panel or clothing guard.
Pay attention to the same distance left and
right!
(1) To insert or remove the quick-release axle
tting:
• loosen the screw connection (B) of the
tting (also the lock nut (2E) on the
inside),
• Turn the complete tting (C) to the
desired position and
• Tighten all screw connections again
(tightening torque of nuts M18 tting

To adjust the caster adapter:
• (1) loosen the screw (A), also on the
frame inside, with which the adapter is
attached to the frame tube,
• loosen the screw (B),
• bring the adapters into an exactly vertical position by turning the adjustment
disc (C) (with a at-head screwdriver),
• check the position by applying an angle.
• Retighten all screws; Screws (A) with 9
Nm, screw (B) with 7 Nm
• After each change to the drive wheel,
the steering head inclination must be
readjusted.
Safety nuts may only be used once. Once loosened safety nuts must be replaced by new
ones.
An incorrect steering head inclination leads to cornering through the castor wheels to
disturbing and obstructive "ascent and descent".
To replace the caster:
• (2) loosen the screw (A) on both sides,
• remove the steering wheel,
• put the new steering wheel on the sleeves.
• Then set the appropriate distances for
the existing steering wheel fork steering
wheel combination

3.7.1 Trum brake
The brake force of the drum brakes is set ideally by our technicians.
For safety reasons it is recommended to check the functionality regularly since a readjustment of the brake force or even a replacement of the Bowden cables becomes necessary from
permanent use.
(1+2) The following parts of the drum brake
are of importance in order to adjust the brake
force.
• setscrew (A)
• lock nut (B)
• push-on nipple (C)
• holder (D)
• inner cable (E)
• locking lever (F)
• clamp (G)
• brake shoe (H)
To install the Bowden cable:
• (3) place the push-on nipple (C) with the
setscrew (A) and the lock nut (B) at the
bottom end in the holder (D),
• guide the inner cable (E) through the
clamp (G),
• place the clamp (G) in the locking lever
(F) and
• push the locking lever (F) slightly forward toward push-on nipple (C), so that
a slight pull between clamp and push-on
nipple occurs.
• Tighten the clamp (G).
• Put the wheel back on and check if the
brake shoes (H) already grind against
the brake pad.
• For this, jack up the wheelchair or tilt it to
the side. The wheel must be able to turn
unhindered.
• Should the brake shoes grind (without using the control lever), loosen the
clamp (G) and
• give the locking lever (F) more room.
• After, retighten the clamp (G).

pressure, wetness, dirt, snow, ice, etc. or
worn tire tread or too large a distance between brake pressure pin and tire.
When the brake is open, the maximum distance between brake pressure pin (A) and tires
is:
Standard KHB max. 21 mm,
Pull-to-lock brake max. 11 mm,
KHB with roll-back lock max. 11 mm,
(Reserve technical changes)
