7:4 Changing the front fork
Unscrew the protective stopper from the front fork attachment in order
to reach the retaining nut. Unscrew the nut and remove the front fork.
Take the washer from the fork's axle and place it on the new fork (with
the bevelled side (A) towards the fork). Insert the new fork into the at-
tachment. It is important that the washers in the attachment (under the
retaining nut) are in the correct order, with the spring washer (B) in the
middle. Tighten the retaining nut until it locks, then loosen it
1/2 -1 turn. This should give the spring washer the correct tension
which reduces the risk of the castor wobbling.
Tools: 19mm socket wrench and Phillips screwdriver
(!)
Also adjust the angle of the front fork attachment, see para 7:3
7:5 Rear wheel with quick release hub (option)
Press in the button on the wheel hub and slide the axle completely into
the shaft. Release the button and ensure that it pops out completely, and
that the wheel is securely mounted.
Always ensure that the wheel is securely mounted, and that the
button pops out fully.
7:6 Adjusting the brakes
The brakes are variably adjustable.
-
Loosen the nut (A) a couple of turns so that the brake block is
about 20mm from the tyre when the brake is not applied.
-
Make sure the brake sits securely in its track and tighten the nut.
Test the brakes.
Tool: 10 mm spanner
The effectiveness of the brakes is dependant upon the amount
of air in the tyres. The brakes are parking brakes only and should
not be applied when the wheelchair is in motion.
7:7 Seat cushion (accessory)
The cushion can be made even more comfortable by the use of a
comfort wedge which rounds-off the front edge of the seat.
Remember: Push the cushion all the way in, with the rounded corners
against the backrest.
The cushion is a standard model and is not suitable for users
with sitting sores.
