SERVICE MANUAL
94°
74°
90°
Adjustment from 16° close, tilted frontward (74°) to 4° open, tilted backward (94°) with respect to 90° to the seat.
If you need to open (tilt backward) the angle, before proceeding, with the adjustment, fold the backrest, loosen the nut C and screw the bolt
B that determine the end run, that it the point where it will lean on the frame. Such operations are not necessary when you need to close (tilt
forward) the angle.
The adjustment can be performed thanks to the two bolts A sliding along the slots through which they pass and fix the backrest tube.
Therefore, loosen the two bolts A on both backrest plates, tilt the backrest to the desired inclination and securely tighten the bolts.
Now check the locking system.
If the locking pin D does not lock, or there is too much play, it is necessary to adjust the end run bolt B.
Loose the nut C, fold the backrest and screw or unscrew the bolt B.
Open the backrest and check if it locks and its play.
To check the play, with the locked backrest, gently pull back it and forth.
If the play is still a lot, loosen the bolt B, whereas, if the backrest does not lock, screw the bolt B.
The correct adjustment is when the pin locks and the play is minimum. Then screw the nut C towards the tube.
Not only does the end run bolt B reduce the backrest play, but also it is very important as point of support of the backrest. In fact if it is badly
adjusted (a lot of play) the lock pin D will support all the backrest stress and it may be damaged or even brake.
Remember that the backrest angle can affect the point of balance of the wheelchair. In fact, with tilted backward backrest (open angle),
the wheelchair becomes less stable.
