Dirt can impair the function of the seat,
So make sure you keep your seat clean.
Upholstery does not need to be removed from
the seat frame for cleaning.
Caution: take care with the
backrest - it may jerk forward and
cause injury!
When cleaning the backrest
cushion, the backrest must be
held in place when operating the
backrest lever.
ATTENTION: Do not clean the seat with a
pressure washer!
When cleaning the upholstery, make sure the
upholstery is not soaked.
Use standard commercially available uphol-
stery or plastics cleaning agent. Test first
for compatibility on a small, concealed area.
