BALANCE AND STABILITY
Each attachment can be adjusted in three positions:
I = the chair becomes easy to propell, less stable
II = middle position
III = the chair becomes stable, less easy to propel
Do not touch this
screw!!
Tools: 5 mm Allen Key
10 mm Fixed spanner
Tools: 5 mm Allen Key
13 mm Spanner
Circlip pliers
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 set-
ting. 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 tipping
backwards), though slightly less manoeuvrable. How-
ever, the chair also becomes somewhat more sus-
ceptible to tipping forwards. This can be countered
by fi tting extended (forwards) castor mountings.
If the seating section is located in the rear position
(I) the chair becomes more manoeuvrable, though
somewhat less stable (in regard to tipping backwards).
This can be countered by lowering the anti-tip de-
vice, with which the chair is fi tted. 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 upper fi ttings (A), and
the lower(picture 2)The upper two are used to
move the chairs seating section forwards and back-
wards and the lower enable you to move the fi t-
ting for the chairs angle adjustment mechanism.
It is important that all four fi ttings are adjusted and
secured in the same relative positions (table 3).
1. Adjust the upper attachment.
Take away the seatcushion, seat plate and legrests.
Put the chair on it's backrest. Adjust each of the
fittings in this way: Slacken the screw (B) on the
upper side of the fitting by a couple of turns, but
do not unscrew it completely. Unscrew screw (C)
and turn the fitting until the correct position (I, II
or III) is aligned with the screw hole in the frame
and then re-tighten screw (C). Then, re-tighten
screw (B).
2. Adjust the lower attachment.
Put the gas piston in poistion. To get right poisition
look in table (3). Put the distance (D) between
the gas piston and the attachment. Asselmble the
screw (F) and the washers (E). Tighten the nut (G).
NB – There is a greater risk of forward tip-
ping when the seat is extended to the front.
