Chair adjustments
Knee lever brake (RXS only)
and wheel lock adjustment
To adjust, loosen the two screws
(1) on each clamp (2), and the
screws (3 - Fig. 35) on the
underside of each clamp (note the
screws are shown removed for
clarity). Using a 5mm Allen key turn
one of the screws anticlockwise ¼
turn (Fig. 34 and 35). Repeat the
process with the other screws.
Loosen the four screws until the
clamp can slide freely. Slide the
clamp towards the rear wheel until
the grip bar (4) embeds into the
tyre (5) 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 four
screws as above. Slide the
mounting bar (6) 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/knee lever brakes 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.
