Chair adjustments
Wheel locks
To adjust, loosen the screws (1) on
the top of each clamp (2). Using a
5mm Allen key turn one of the
screws anticlockwise ¼ turn
(Fig. 37). Repeat the process with
the second of the two screws.
Loosen the screws until the clamp
can slide freely. Slide the clamp
towards the rear wheel until the grip
bar (3) embeds into the tyre (4)
approximately 4mm (3/16") when in
the locked position. Tighten the
screws to a torque setting of 15Nm.
Some adjustments to the wheel
lock position can be accomplished
without moving the clamp. To
adjust, loosen the two screws as
above. Slide the mounting bar (5)
forward or backwards and rotate it
to the correct angle position. The
grip bar should embed into the tyre
approximately 4mm (3/16") when in
the locked position. Tighten the
screws to a torque setting of 15Nm.
Warning:
Wheel locks when properly
adjusted, prevent the rear wheels
from turning when the chair is
stationary. Always adjust the wheel
locks after making any changes to
the rear axle sleeves position, so
that the grip bar embeds into the
tyre approximately 4mm (3/16")
when in the locked position.
