Setting The Front Height Of The Seat; Setting The Perpendicularity Of The Front Fork Support Plate - OFF CARR ALHENA Instruction Manual

Be sure to have chosen the same position in both wheel-keeping compasses on the back of the frame. Asimmetric combinations
produce instability.
Once changed the position of the back wheels, it is essential to adjust the front forks' perpendicularity (see.
par.3.3) and the positioning of the parking brakes (see par.3.5) and, if necessary, to position the clothes-guards
(see par.3.4).
3.2

Setting the front height of the seat

It is possible to vary the front height of the wheelchair by changing the diametre of the front wheels or by choosing a different
position of the wheel on the fork:
Unscrew completely one of the "D" screws and remove
the "E" pern, on the side of the non-removed "D" screw,
being careful to the positions of the "F" spacers
If necessary, change the wheel
Position the wheel's hole in level with the most
appropriate fork hole;
Insert the "E" pivot, being careful to the original positioning of the "F"
spacers;
Fix the "D" screw.
3.3

Setting the perpendicularity of the front fork support plate.

Once the front and rear height seat are set-up is necessary to verify and if necessary to adjust the perpendicularity of the front
fork support plate. This adjustment is important to reach the maximum agility and the best driving sensitivity fa the wheelchair.
Remove the protective cap "A";
Loosen the two screw "B" that secure the fork support
plate;
Rotate the upper eccentric nut until the plate reaches
the perpendicular position;
tighten the two screws "B";
place again the protective cap "A".
Note: the two eccentric nuts have different profile. The upper nut with round profile allow a continuos adjustment of the plate
perpendicularity. In the lower position is assembled the exagonal profile eccentric nut. Is suggested to rotate it only
when the rotation of the upper nut is not enough to reach the right position.
