Link Rear Suspension - Quickie Helium Notice D'utilisation

Brakes...
The wheel locks have not been designed to be used as
brakes for a moving wheelchair. The wheel locks should
therefore never be used to brake a moving wheelchair.
Always use the hand-rims for braking. Make sure that the
gap between the tyres and wheel locks complies with
given specifications. To re-adjust, loosen the screw and
set the appropriate gap. Then re-tighten the screw
(Fig. 4.3 and 4.4).
CAUTION !
After each adjustment of the rear wheels, check the
wheel lock gap and re-adjust if necessary.
Brake lever extension
The longer lever helps to minimise the effort needed to set
the wheel locks.
The brake lever extension is screwed to the brakes. By
raising this, it can be flipped forward (Fig. 4.5).
CAUTION !
Mounting the wheel lock too close towards the wheel will
result in a higher effort to operate. This might cause the
brake lever extension to break!
Leaning onto the brake lever extension while transferring
will cause the lever to break! Splashing water from tyres
might cause the wheel lock to malfunction.
CAUTION !
Incorrect mounting of the wheel lock will result in a higher
effort to operate.
This might cause the wheel lock extension lever to break.
Compact brakes
Compact brakes are underneath the seat sling and are
operated by pulling the brakes towards the rear, in the
direction of the tyre. For the brakes to work properly, this
must be pulled until it reaches the stops, (Fig.4.6).

The One-arm Wheel Lock
The one arm wheel lock is underneath the seat sling and
is operated by pulling the brake lever, which is located on
the left or right side, towards the rear, in the direction of
the tyre. For the brakes to work properly, this must be
pulled until it reaches the stop, (Fig.4.6.1)
Adjustment
To adjust the brake, loose the screws (1) and mount the
wheel lock where it will work in a proper way (Fig,4.6.2).
CAUTION!
Incorrect mounting of the one arm wheel lock can lead to
serious injury of the user and other people.

a. To stiffen the suspension, turn the spring preload
adjustor (A)clockwise (looking up at the suspension
system from underneath the wheelchair).
b. To soften the suspension, turn the spring preload
adjustor (A) counter-clockwise (looking up at the
suspension system from underneath the wheelchair)
2. Alignment of Suspension Link Arms
