7.12 Caster wheels and caster forks
WARNING
Failure of caster wheels or caster forks
Falling, severe injury due to the wheelchair tipping over
► Regularly inspect the caster wheels and caster forks for damage.
► Regularly clean and oil the caster wheel axles and the threaded axles on the caster forks, especially in case of
stiffness.
► Inform the responsible qualified personnel in case of permanent changes to the driving characteristics.
CAUTION
Incorrect caster wheel position when leaning forward in the wheelchair
Tipping over, falling due to incorrect caster wheel positioning
► 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 caster wheels and caster forks ensures the ability to hold a straight line and navigate bends
securely.
7.12.1 Approach in case of stiffness
In case of stiffness, the caster wheel axles should be cleaned and oiled.
Oiling the caster axle
1) Remove dirt (e.g. hairs) from the caster wheel axle between the caster wheel and caster fork (see fig. 39,
item 1).
2) Lubricate the caster axle between the caster wheel and caster fork with a few drops of thin, resin-free oil (sew
ing machine oil).
