13) REVERSIBILITY OF SAFETY COUPLINGS
In business, there are not only wheelchairs equipped
with thrust handles (Fig. 34/a) but also wheelchairs
in which the rear thrust system consists of a shackle
(Fig. 35/a) placed in the rear part on the backrest.
In these cases, the safety couplings (Fig. 36/a) can be
rotated by 90° since they are equipped with a second
hole (Fig. 36/b). in this way, the red hook (Fig. 36/c)
grasps the shackle from the bottom and not lateral-
ly, and clamp the wheelchair to the steering bar as
safely as the traditional wheelchairs.
In order to carry out this operation follow this procedure:
1) remove the clamping screw placed in the edge of
the steering bar (Fig.36/d) and loosen the locking
handwheel (Fig. 36/e);
2) extract the safety clamp (Fig. 36/a) toward the out-
side (Fig. 36/f);
3) rotate the safety coupling (Fig. 37/a) of 90° (Fig.
37/b), to the left for the left one and to the right for
the right one;
4) insert the rotated coupling through the hole (Fig. 37/c)
into the arm (Fig. 37/d). Screw again the setscrew
placed in the edge of steering bar arms, previously
unscrewed;
5) approach the steering bar (Fig. 38/a) to the seat back
backrest of the wheelchair (Fig. 38/b). Pull the safety
piston (Fig. 38/c), hook the shackle (Fig. 38/d) using
the hook (Fig. 38/e) and release the piston (Fig. 38/c).

NOTE: ensure that the piston (Fig. 38/c) is placed
under the red hook (Fig. 38/e) so that it can't be
released from the wheelchair (Fig. 38/d);
6) lock the coupling turning the handwheel (Fig. 38/f).
7) lift the arms (Fig. 38/g) until the point in which the red
hook (Fig. 38/e) is placed in contact to the shackle
(Fig. 38/d).
