The centre of gravity is adjusted by moving
the wheel to another position on the wheel
fastening. The wheel fastening has three
holes. The back holes make the chair most
safe with regard to tipping, whereas the
front holes make the chair easier to roll.
20” and 22” driving wheels can be placed
in any of the three holes, but 24” driving
wheels can only be placed in the two
backmost holes.
Always adjust the brakes after you
have adjusted the balance point!

the outward nut (37A) with a 24 mm
spanner while restraining the inward nut
with a 24 mm spanner
• Move the wheel casing to the desired
hole and screw the nut on again
