Check the stability with the user in the chair when the
chair has been adjusted. Adjust the angle of the seat and
backrest backwards to their maximum setting. Check
the risk of tipping. Re-adjust the balance of the chair
and/or anti-tip devices to obtain a chair that is stable
in all situations.
By moving the seating section (seat plus backrest) either
backwards or forwards, in relation to the lower frame
(and also in relation to the rear wheel and castors) you
also alter the chairs manoeuvrability and stability.
If the seating section is located in the forward posi-
tion (III) the chair is more stable (in regard to tip-
ping backwards), though slightly less manoeuvrable.
However, the chair also becomes somewhat more
susceptible to tipping forwards. If the seating section
is located in the rear position (II) the chair becomes
more manoeuvrable, though somewhat less stable (in
regard to tipping backwards). This can be countered
by lowering the anti-tip device, with which the chair is
fitted. Subsequently, you have a wheelchair that is both
manoeuvrable and safe.
If you want to alter the balance of the wheelchair it is
necessary to adjust the two fittings (A) and position of
gas piston (B) on frame bracket.. The two fittings are
used to move the chairs seating section forwards and
backwards and the gas piston enable you to move the
fitting for the chairs angle adjustment mechanism.
It is important that the two fittings and the gas piston
are adjusted and secured in the same relative positions
(table 3).
1. Adjust the upper attachment.
Take away the seat cushion, seat plate, legrests and
wheels. Put the chair with it's front facing down.
Adjust each of the fittings in this way: Slacken the
screw (C) on the upper side of the fitting by a
couple of turns, but do not unscrew it completely.
Unscrew screw (D) and turn the fitting until the
correct position ( II or III) is aligned with the screw
hole in the frame and then re-tighten screw (D).
Then, re-tighten screw (C).
NB – Never touch screw (E)!
2. Adjust the lower attachment.
Pull out pin (F) on the gas piston by opening clamp
and put the gas piston in position. For the right
position, see table (3).
NB – Be sure the pin is secured again with
clamp.
NB – There is a greater risk of tipping forward
when the seat is extended to the front.
