2 General information
2.5 General safety information
Check before every ride:
• Frame, back tubes, add-on parts and accessories for visible damage, bends, cracks or
missing / loose screws,
• Wheels / axles on tight t,
• sucient tire pressure, tire prole,
• Functionality of the brakes,
• tight t of the angle adjustment elements / eccentric clamps,
• rm closure of the seat plate / back / foot plate,
• Functionality of the anti-tipper / seat and back straps,
• whether all previously dismantled parts are reinserted and rmly locked.
There is a risk of injuries (e.g. crushing) on all rotating, rotatable or foldable parts, also
during adjustment and repair work as well as during transport.
All wheelchair parts are to be handled properly. Do not throw or drop removable parts!
Before starting the test, repair or adjustment work, clean / disinfect the wheelchair and
secure it against tipping over and / or falling.
Use only original spare parts.
Safety nuts may only be used once. Safety nuts that have been loosened must be repla-
ced with new ones.
Only regular maintenance of all safety-relevant parts on the wheelchair by a qualied
rehab workshop protects against damage and maintains our manufacturer's warranty.
Lifespan
Use beyond the specied service life leads to an increase in the residual risks and should
only be carried out after careful, qualied consideration by the operator. If the service life is
reached, the user or a responsible person should contact the specialist retailer. There you can
get information about the possibility of processing the product.
Combination with products from other manufacturers
The wheelchair may only be combined with the additional electrical drives approved by the
manufacturer. Restrictions or adjustments as well as the cultivation itself are the responsibility
of the provider of the additional system or the authorized specialist trade. Please ask the ma-
nufacturer of the additional drives for the requirements.
In the combination of a wheelchair and an additional electric drive, particular loads occur
which can lead to damage to the wheelchair. Approach obstacles slowly and overcome them
carefully so that little force is exerted on the caster wheel, drive wheel and the wheelchair as a
whole.

3.1.1 Activity
3.1 Wheels assembly
(A) (B)
Go carefully to the maximum and the user (!) desired point of tilt.
(1) To set the activity
• remove both drive wheels,
• loosen the nut and the screw (1A).
• Loosen the screw (1B) until it no longer
engages in the holes (1D).
• To make the chair more active, move
the entire holder forward on both sides.
• To adjust the chair more passively,
move the entire holder backwards on
both sides.
• The move must be done in parallel on
both sides.
• Re-establish the clamp connection by
inserting the screw (1B) into the selec-
ted hole (1D).
• Tighten the screw and nut (1A) again.
The further back you move the caster wheels, the greater the risk of the wheelchair tip-
ping forward when getting in and out.
The further you mount the drive wheels with the perforated plate to the front, the greater the
risk of the wheelchair tipping backwards.
(D)
(1)
3.1.2 Seat height in front
(2)
(A)
(B)
(2) The front seat height is adjusted via the
position of the caster wheel in the caster wheel
fork.
• Completely remove the screw connec-
tion caster wheel / caster wheel fork
(2A),
• Fasten the caster wheels in the desired
hole (2B) on both sides,
• Tighten the screw again.
After every change you have to check the
vertical tilt of the caster head and correct it if
necessary (see chapter caster head tilt).
Hair, lint, dirt, etc. collect on the bearings of the caster wheels, making the caster wheels
sti. Remove the caster wheels at short intervals and thoroughly clean the forks, axles and
sleeves.
Please proceed in the same way with plastic forks.
* Not with thru axle (castor wheel adapter)
Make sure that the mount is firmly seated and that there is no longer any play!

(A)
3.1.4 Positioning the steering angle
(3)
(B)
(C)
After every change to the drive wheel,
the functionality of the parking brakes must
be checked and the caster wheels and the
wheel track must be readjusted.
As a rule, the seat height at the back is selec-
ted approx. 2-3 cm lower than the seat height
in front in order to achieve a safe and comfor-
table sitting position with good distribution
of the seat pressure and to avoid "slipping
forward". However, other settings can also be
useful in individual cases.
• (1) Remove the drive wheels,
• remove the side panels / clothes guards
with the screws (1A) (simply remove the
plug-in side panels),
• (2) Remove the screw connection and
the threaded sleeves on the clamping
ange (2A),
• move the clamping ange to the desi-
red holes (2B)
• attach the screws and threaded sleeves
and tighten all screws again.
• Mount the side parts and put the drive
wheels back into the quick-release axle.
The clamping anges must be attached at the
same height on both sides. The lateral dis-
tance between the top tires and the side panel
should be as small as possible, but at least 10
mm.
An incorrectly set steering axis angle can lead to caster wheel utter and when cornering (due to
the wheel caster) to obstructive "uphill and downhill driving".
The steering axis angle must be readjusted after
each change to the rear and front seat height.
For adjusting the steering angle:
(A)
(A)
• Loosen the screws (3A) + (3C)
• Unscrew the threaded pins (3B) suci-
ently to be able to readjust the steering
head angle.
• Tighten the screws (3A) and (3C) so
that the steering head can just be mo-
ved and set the steering head angle to
90 °.
• Carefully screw in one of the threa-
ded pins (3B) until the rst resistance.
Then tighten the second set screw (3B)
against it.

To change the camber you have to order a
suitable camber adapter.
The following camber adapters can be selec-

Please ensure that there is sucient distance
to the side panel so that the drive wheel does
not touch the side panel when it is loaded
from the side.
After every change to the camber adap-
ter, it must be checked that the distance left
and right to the clamping ange is the same.
If you want to change the distance to the
frame, rst loosen on one side (2A) and (2B)
and move the adapter to the desired position.
Tighten the screw connections (2A) and (2B)
again. Now proceed in the same way with the
other side.
Be sure to check the functionality of the knee lever brake as well as the wheel toe-in and
the caster head angle of the caster wheels and readjust them if necessary.

(2) First check the tire pressure of the drive wheels (required information on the tire casing). To
adjust the brake, loosen both screws (C) on both sides, bring the brake body into the correspon-
ding position and tighten the screws (C) again.
3.5.2 Standard parking brake
(1+2) Every wheelchair is equipped with two
parking brakes. They consist of brake pressure
bolts (A), brake lever (B) (if necessary with an
extension) and adjusting screws (C).
Parking brakes are used only to lock the
wheels in a rest position. They are not desi-
gned to slow down the wheelchair while it is
in motion.
The correct functioning of the brakes
can be impaired by:
• tire pressure too low,
• Wetness, dirt, snow, ice, etc.
• worn tire prole and
• Too great a distance between the brake
pressure bolt and the tire.
Check the fastening of the brake pressure
bolts on the inside of the wheelchair at regular
intervals(D).
Readjust the brakes after making any
changes to the drive wheels. The drive
wheels of the wheelchair with occupants
must not slip on a ramp with a 12% incline
when the parking brake is on.
When the brake is open, the maximum dis-
tance between the brake pressure pin and the
tires is determined as follows:
Standard-KLB 21 mm
Pull-to-lock-Brake 11 mm
Cable brake 6 mm
(Technical changes reserved).
