Danger as a result of incorrect assembly or settings
CAUTION
Risk of tipping as a result of incorrectly set wheels. Extreme settings (e.g. rear wheels mounted in
the most forward position) combined with an unfavorable body posture can cause the wheelchair to
tip even on level ground. Avoid extreme settings. For transfemoral amputees, the rear wheels must
be shifted backwards. Use of an anti-tipper is required.
CAUTION
Risk of tipping as a result of missing or incorrectly mounted anti-tipper. Under no condition
should the anti-tippers be used as transport wheels, e.g. when wanting to push the wheelchair while
the rear wheels are removed. The anti-tippers must audibly lock in place before they are able to bear
loads. Appropriate positioning must be verified by the user or by an attendant.
CAUTION
Risk of tipping as a result of using a different diameter or position of wheel. If the size and
position of the casters or the rear wheel size are modified, the casters may flutter when driving at
higher speeds. This can lead to blocking of the casters 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. You must not be able to remove the rear
wheel with out pressing the quick-release button.
Danger as a result of improper use of the tires
CAUTION
Accident risk due to insufficient or excessive tire pressure! The effectiveness of the wheel lock
and the overall driving quality are dependent on appropriate tire air pressure. The wheel locks are
only effective with appropriate air pressure and proper adjustment (approx. 5 mm distance, subject
to technical changes).
Before starting to use your mobility base with seating shell, make sure that the tires are inflated
to the correct specifications. The required air pressure is printed on the side of the tire. For rear
wheels, it should be at least 108 PSI (7.5 bar/350 kPa). Properly inflated rear wheel tires and
equal air pressure in both tires considerably improve the maneuverability of your wheelchair.
CAUTION
Risk of accident as a result of bad tires. Insufficient tread depth of the tires reduces traction.
When using your wheelchair in public traffic, you are subjected to public traffic regulations.
