7.8.1 Special requirements for the FrogLeg caster fork

The spring-mounted caster fork allows for smoother negotiation of obstacles and offers damping on uneven terrain.

Ottobock recommends using smaller caster wheels for outdoor use. Due to the design, a slight fluttering of the

caster wheels may occur when driving quickly and using larger caster wheels. The user should adjust their driving

in this case.

In case of stiffness, the caster wheel axles should be cleaned and oiled.

Oiling the caster axle

1) Remove dirt (such as hairs) from the caster axle between the caster wheel and caster fork.

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).

The wheel locks secure the parked wheelchair against rolling away.

WARNING

Improper use of the wheel lock

Falls due to abrupt braking, rolling away of the product, crushing of hands

► Do not use the wheel lock as a driving brake.

► Always engage the wheel lock on both sides.

► Engage the wheel lock to prevent the product from moving when it is parked on uneven ground or during

transfers (e.g. into a car).

► Do not reach between the rear wheel and the wheel lock when driving the product.

lock the drive wheel securely when stationary.
