6 Preparing the product for use
6.1 Assembly
CAUTION
Failure to verify readiness for use before putting into operation
Tipping, falling due to incorrect adjustment or installation
►Before you start using the wheelchair for the first time, check the chosen wheelchair settings with the support
of authorised personnel.
►After every assembly, check for proper mounting of the drive wheels. The drive wheels must be securely
locked in the quick-release axle housings.
►Pay particular attention to the stability against tipping and free running of the drive wheels.
►Check the tyre pressure. The correct tyre pressure is printed on the sidewall. Ensure that the pressure is the
same in both tyres.
The wheelchair is preassembled on delivery:
• Basketball version, Basketball ULW version (ultra lightweight; see fig.4)
• Rugby version (see fig.5, the "Rugby Offense" version is illustrated)
It takes just a few simple steps to prepare the wheelchair for use:
1) Attach the drive wheels to the quick-release axle mountings (see page24).
2) If necessary: Fit the seat cushion. The seat cushion is secured against sliding by being pressed on to the

7.5 Adjusting the back support upholstery / seat upholstery
7.5.1 Adjusting the back support upholstery
INFORMATION
A well-adjusted backrest provides lasting comfort for the wheelchair user and reduces the risk of secondary dam
age and pressure zones. Do not create too much pressure.
INFORMATION
Ensure that the user's pelvis is positioned as far back in the wheelchair as possible, i.e. between the backrest
tubes.
The back upholstery is attached to the frame tubes with hook-and-loop straps.
1) Fold up the backrest padding.
2) Open and loosen the hook-and-loop straps one after the other (see fig.13).
3) Sit and position the user in the wheelchair.
4) From the bottom to the top, adjust the tension of the hook-and-loop straps to the weight and anatomical condi
tion of the user and fasten the straps (see fig.14).
INFORMATION: The two ends of the hook-and-loop strap have to overlap by at least 100mm in each
case.
INFORMATION: Adjust the respective lower hook-and-loop straps somewhat tighter.
INFORMATION: Deviating adjustments may be required in specific cases; this is the responsibility of
the attending therapist.

7.5.2 Adjusting the seat upholstery
The seat upholstery usually does not need to be adjusted during the initial fitting. However, the tension can be
changed.
The seat upholstery is attached to the frame tubes with hook-and-loop straps.
1) If necessary: Place the seat cushion on the seat upholstery.
2) Open and loosen the rear hook-and-loop straps. Attach a hook-and loop strap from the middle diagonally over
the straps to secure them (see fig.15).
3) Sit and position the user in the wheelchair.
4) Adjust the tension of the hook-and-loop straps to the weight and anatomical condition of the user, and fasten
them one after the other (see fig.16).
INFORMATION: The two ends of the hook-and-loop strap have to overlap by at least 100mm in each
case.
INFORMATION: Keep the respective front hook-and-loop straps tight.
INFORMATION: Deviating adjustments may be required in specific cases; this is the responsibility of
the attending therapist.
15 16
7.6 Adjusting the leg supports
The distance between the footplates and the sitting surface influences sitting stability. The height adjustment acts
on the pelvis and ischial bones.
7.6.1 Adjusting the height of the foot plate
The height of the foot plate can be subsequently adjusted by inserting spacers.
1) Loosen and remove the screw connection under the foot plate (see fig.25).
2) Insert the four spacers according to the desired height.
3) Firmly retighten the screw connection.
