CAUTIOn
Risk of tipping as a result of missing or incorrectly mounted anti-tipper. Under no conditions should
the anti-tipper assume the function of transport wheels, for example to transport a person in the wheel-
chair with the rear wheels removed. The anti-tipper must audibly lock in place, before it is able to bear
loads. Firm seating must be verified by the user or by an attendant.
CAUTIOn
Risk of tipping as a result of changed diameters /mounting positions of the wheels. If the size and
position of the caster wheels or the rear wheel size are modified, the caster wheels may flutter when
driving at higher speeds. This can lead to blocking of the caster wheels and cause the wheelchair to tip
over. For this reason, you should always maintain the factory settings or, if modifications are required,
ensure that the wheelchair frame is aligned horizontally (see "Adjustment /assembly instructions").
CAUTIOn
Risk of falling as a result of unintentional loosening of the rear wheels. Always make sure that the
quick-release axles are correctly set on the rear wheel. The rear wheel must not be removable without
the button of the quick-release axle being depressed.
CAUTIOn
Risk of pinching, crushing, and falling due to unsecured screw connections.
• After any adjustment/ readjustment work, retighten the mounting screws/nuts firmly. Observe the
torque specifications.
• Any time you loosen a screw connection with thread lock, replace it with a new screw connection or
secure the old screw connection with medium strength thread locker (e.g. Loctite® 241).
CAUTIOn
Risk of falling due to missing self-locking nuts.
Always replace self-locking nuts with new self-locking nuts after disassembly.
Danger as a result of improper use of the tyres
CAUTIOn
Risk of accident as a result of insufficient or excessive tyre pressure. The effectiveness of the
wheel lock and the overall driving quality are dependent on adequate air pressure. The wheel locks
are only effective with sufficient air pressure and proper adjustment (approx. 5 mm distance, subject
to technical changes).
Before starting to use your wheelchair, check that the tyres are inflated correctly. The required air
pressure is printed on the side of the tyre. For rear wheels, it should be at least 3.5 bar. With properly
inflated rear wheels and even tyre pressure on both sides, your wheelchair is much easier to operate
and manoeuvre.
CAUTIOn
Risk of accident as a result of bad tyres. Insufficient tread depth of the tyres reduces adhesion.
Please note that when you operate your wheelchair in public road traffic, you are subject to road traf-
fic regulations.
