Castors / Castor Forks; Brakes; Using The Knee Lever Wheel Lock - Otto Bock Ventus Instructions For Use Manual

Usage

6.3.6 Castors / castor forks

CAUTION
Incorrect caster wheel positioning
Risk of falling or tipping when leaning forward in the wheelchair
► Prior to activities that require you to bend forward in the wheelchair (e.g. tying your shoes), maximise the sta­
bility of the wheelchair. In order to do so, push the wheelchair backwards until the caster wheels turn forward.
The combination of castor wheels and castor forks ensures the ability to hold a straight line and navigate curves.
The different castor wheels (e.g. light rollers, design rollers, full rubber rollers, skate rollers) or castor forks (e.g.
castor forks with or without suspension) have been chosen by the qualified personnel according to the needs of the
user.

6.3.7 Brakes

CAUTION
Improper use of the wheel lock
Falling due to abrupt braking, rolling away of the wheelchair, crushing the hands
► Do not use the knee lever wheel lock as a driving brake.
► Always engage the wheel lock on both sides.
► When parking on uneven ground or during transfers (e.g. into a car), secure the wheelchair by activating the
knee lever wheel lock.
► Do not reach between the rear wheel and the knee lever wheel lock when driving the wheelchair.
► Ensure the knee lever wheel lock is properly adjusted (approx. 5 mm gap to the tyres, technical changes
reserved) and the tyre pressure is sufficient.
The wheel locks secure the parked wheelchair against rolling away.
