5.2 Options
The standard model can be fitted to the user's personal requirements thanks to a large range of options. For use of
these options: see Page22 ff.
5.3 Storage
5.3.1 Storage during daily use
The product should always be stored so it is protected against external influences.
5.3.2 Storage during extended disuse
The product must be stored in a dry place. Specific information for extended storage: see Page43.
It is not necessary to disassemble the product.
Maintain sufficient clearance from sources of heat. If the product is parked for an extended period of time or the
tyres overheat (e.g.in the vicinity of radiators or in case of exposure to strong sunlight behind glass), the tyres may
become permanently deformed.
During extended storage, the knee lever wheel lock on wheelchairs with PU tyres (=tubeless tyres) must be
released since tyre deformation may otherwise result.
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 qualified personnel.
►After every assembly, check for proper mounting of the drive wheels. The quick-release axles must be
securely locked in the receiver bushings.
►Pay particular attention to the stability against tipping, free running of the drive wheels and correct function of
the wheel locks.
►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 at delivery (see fig.3). A few simple steps are sufficient to prepare the wheelchair
for use:
1) Attach the drive wheels to the receiver bushings (see Page29).
2) If necessary: Fold up the backrest (see Page26).
3) If necessary: Fit the seat cushion. The seat cushion is secured against sliding by being pressed on to the
hook-and-loop fastener (see Page25).
4) If necessary: Fasten the calf strap to the frame tube above the caster attachment device (see Page24).
5) If necessary: Fold up the push handles (see Page27).

7.5 Adjusting the wheel locks
WARNING
Failure to verify brake functionality
Accident, user falls due to incorrect adjustment and improperly inflated tyres
►Check the correct spacing between the wheel lock bolt and tyre (see the following section for details).
►Check the correct position of the wheel lock bolt relative to the tyre. During braking, the wheel lock bolt has to
cover at least half the tyre width.
►Always carry out adjustments to the wheel lock on both sides.
►Ensure that the user can operate the wheel lock without great effort. The force required to do so must not
exceed 60N.
►Check the tyre pressure of the drive wheels. Note the information in the section “Technical data” or on the tyre
sidewall.
►Only use original drive wheels with a verified maximum radial out-of-round of 1mm.
Adjustment is required if the braking force decreases.
Special Requirements for Adjustments (All Types of Wheel Locks)
Depending on the adjustment, it may be necessary to rotate or replace the support for the wheel lock. This makes
further wheel lock adjustments possible.
7.5.1 Adjusting the knee lever wheel locks
1) Loosen the Allen head screws in the clamp brackets (Invader: see fig.10, item1; Invader Heavy Duty: see
fig.12, item1).
2) Adjust/move the support for the knee lever wheel lock to any position in the clamp bracket (Invader: see fig.10,
item2; Invader Heavy Duty: see fig.12, item2).
If necessary: Slide and twist the clamp bracket on the seat tube.
3) When the wheel lock is disengaged, the gap between the tyre and wheel lock bolt must not exceed 5mm (see
fig.11/see fig.13).
4) Tighten the Allen head screws to 15Nm.
→After adjustment, the left and right knee lever wheel locks must both have the same braking force.

3) Install the scissor wheel lock so that the full braking force is reached and the swivelling parts can also move
freely without colliding.
→The scissor wheel lock must not hit the frame when it is open (see fig.15).
→It must be impossible to push the wheelchair with the wheel locks engaged.
4) Re-tighten the Allen head screws to 15Nm (see fig.14).

7.6 Adjusting the back support upholstery / seat upholstery
7.6.1 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.16).
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.17).
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.

7.6.2 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.
Invader, Invader Heavy Duty
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.18).
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.19).
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.

On this version, the seat straps are threaded through metal loops on the frame tube. The adjustment is as
described above.
Please note: This version has two-piece seat straps (hook-and-loop version). A short strap (hook/hook version) is
attached in addition on the loop surface of the seat straps in the area between the seat tubes. The ends of the long
seat strap are then attached to this strap with hook-and-loop.

7.7 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.
7.7.1 Adjusting the lower leg length
The following adjustment instructions only apply to height-adjustable leg supports.
The required leg support height depends on the lower leg length of the user and the thickness of the seat cushion.
The adjustment must be made to exactly the same height on the left and the right so the frame cannot warp.
1) Loosen the mounting screws on both sides (see fig.22, item1).
2) Adjust the lower leg length (continuously adjustable). Ensure that the foot plate bar is inserted into the frame
tube by at least 40mm.
INFORMATION: A mark on the tube of the leg support indicates the minimum distance the tube must
be inserted during installation.
3) Before final attachment, align the leg support to exactly the same height on the left and right:
→Forexample, create a reference plane under the leg support on the left side with the help of a try square
(see fig.22, item2).
→Measure the distance between the reference plane (below) and the black bushing (above) exactly (see
fig.22, item3).
→Align the height of the leg support on the right side with millimetre accuracy as well (see fig.23, item1/2).
4) Tighten the mounting screws to 10Nm.

3) Before final attachment, align the leg support to exactly the same height on the left and right:
→Forexample, create a reference plane under the leg support on the left side with the help of a try square
(not illustrated).
→Measure the distance between the reference plane (below) and the seat clamp (above) exactly.
→Align the height of the leg support on the right side with millimetre accuracy as well.
4) Tighten the Allen head screws on the seat clamps to 7Nm.
