Now install a new tyre as follows:
•
Place one side of the new tyre across the rim.
•
Put the valve through the opening in the rim.
•
Carefully place the tyre around the rim.
•
Add a little air to the inner tube in order to position it comfortably around the rim.
•
Pull the tyre onto the rim as far as possible.
•
Allow all air to escape from the inner tube.
•
Now pull the tyre completely onto the centre of the rim as tightly as possible.
The rim has a room into which the tyre must be pulled, in order to create sufficient space to be able to pull the
complete tyre onto the rim by hand.
•
Pull the tyre completely onto the rim.
Do not use tyre levers to do this, because the inner tube is easily damaged by these. Moreover, the
tyre is easily assembled without tyre levers.
•
Make sure that the tyre is properly fitted onto the rim.
The inner tube may not protrude from under the tyre anywhere!
•
Pump up the tyre.
•
Mount the wheel back onto the wheelchair. See ’Removing the rear wheels’.
2.2.5
Adjusting the pressure brake
The wheelchair is fitted with pressure brakes on the rear
wheels, which the user can operate by hand.
Proper functioning of the brakes is essential. That’s why the
brakes have to be:
•
properly adjusted
•
replaced in time.
Adjust the brakes as follows:
•
Loosen screw (A) one turn using a 5 mm Allen key.
•
Slide brake unit (B) along the tube for the adjustment.
- away from the wheel: brake looser.
- towards the wheel: brake tighter.
•
Tighten the screw in the set position.

2.3.1
Rear wheels
To ensure proper operation of the wheelchair, it is very important that the tyres are kept at the correct pressure.
Soft tyres yield less than optimal driving for the wheelchair. It also costs more energy to move the wheelchair
forward. Moreover, tyre wear when driving on soft tyres is unnecessarily great.
For the right tyre tension, see ‘Product specifications'.
Note when filling the tyres that the pressure never exceeds the maximum specified value provided
in the table 'product specification', or as indicated on the side of the tyre. When in doubt, contact
your dealer / supplier.
For the inspection of the tyres, see the 'maintenance table'.
