SETTINGS
Adjusting the tension of the backrest upholstery
:
1) Lift up the backrest upholstery’s upper flap (1).
2) Loosen the bands.
3) Sit as far back in the chair as you can. If it feels as though you are not sitting far back
enough in the chair, it may be because the backrest upholstery’s lower flap is fastened
too far forward on the seat Loosen the flap (2) and then fasten it further back on the seat
upholstery.
4) Tighten the bands to ensure you have the necessary support.
5) Fold down the backrest upholstery’s upper flap (1).
6) The balance of the wheelchair
(Fig. 12)
U3 Light has a rigid rear axle and the balance is adjusted by moving the position of the
body relative to the rear axle. This is accomplished with moving the backrest into
three di-
ferent positions.
The further back you place the backrest the more ”tippy” the wheelchair
gets. This makes the wheelchair light at the front and more of the weight is moved to the
reawheels. The wheelchair becomes more easy to manouver and easier to ”lift up” on the
rearwheels, to climb obstacles like curbes, thresholds etc. The wheelchair must not be to
”tippy”. Then you risk to tip over and fall backwards. U3 Light comes in two versions, ”U3
Light”, normal balance and ”U2-light
L
”, light balance, check that you have recieved the
version you have ordered. U3 Light has 75 mm between the rear axle and the rearmost
part of the chassis and U2-light
L
, has 100 mm, see fig. 2.
