By changing the seat depth
1-acting on the screws “A” and “B”
that fix SHS holder to the frame:
•
unscrew completely and remove the
screws “A” and “B”;
•
change the rear axle position moving
the SHS holder;
•
fix the “A” and “B” screws.
Operations on the SHS holder have
always to be performed symmetrically
(both on left and right side).
Asymmetrical combinations produce
instability
2- changing the seat depth
•
unscrew completely and remove the
“A” screws;
•
move the telescopic insert until the
desired depth (the extension insert is
already pre-holed with steps of 2
cm);
•
fix the “A” screws.
The operations always have to be
performed symmetrically (both on right
and left side)
•
Pay attention to the proper camber adjustments before fixing tightly the wheel bushes
(see par 3.6);
•
connect again the wheels to the chair checking the proper assembly (see par.2.2);
•
changing the gravity centre is an operation that always has to be performed
symmetrically.
Be sure to choose the same position in both wheel bushes on the back of the frame.
Asymmetrical combinations produce instability.
Once changed the position of the back wheels, it is essential to adjust the front forks
perpendicularity (see. par.3.7), the proper camber of the rear wheel (see par.3.6), and the
positioning of the parking brakes (see par.3.13).
Note:
consider that the further the hub is connected, the more agile the wheelchair is, and the
further back it is assembled, the less active but the safest the wheelchair becomes.
