3.4 Parking Brakes
The parking brakes are used to immobilize the wheelchair
when it is stationary to prevent it from rolling away.
WARNING!
Risk of overturning if you brake sharply
If you engage the parking brakes while you are
moving, the direction of movement can become
uncontrollable and the wheelchair may stop
suddenly, which can lead to a collision or to you
falling out.
– Never engage the parking brakes while you are
moving.
WARNING!
Risk due to wheelchair being out of control
– The parking brakes must be operated
simultaneously.
– Do not engage the parking brakes to slow down
the wheelchair.
WARNING!
Risk of overturning
The parking brakes will not operate correctly
unless there is sufficient air in the tyres.
– Ensure the correct tyre pressure, 11.3 Tyres,
page 43.
CAUTION!
Risk of pinching or crushing
There may be a very small gap between the rear
wheel and the parking brake with the risk that
you could trap your fingers.
– Keep your fingers away from movable parts
when using the brake, always keep your hand
on the brake lever.
The distance between the brake shoe and the tyre
can be adjusted. The adjustment must be carried out
by a qualified technician.
The lever of the push handle can be folded back to
facilitate transfers. To do so, pull up the lever and
fold it backwards.
To operate the brake, refer to paragraph Using the
wheelchair, section 6.2 Braking during use, page 25.

WARNING!
Risk of tipping
If the standard backrest cover become slack, the
tipping point of your wheelchair is changed for
the worse.
– Slack standard backrest cover must be replaced
by a qualified technician.
3.5.2 Adjustable Backrest Cover

Adjusting the backrest cover
1. Remove the backrest cushion A.
2. Loosen the hook and loop strips B on the rear of the
backrest cover by simply pulling on them.
3. Tighten or loosen the strips as required then reattach
them.
WARNING!
Risk of tipping
If the bands are set very loose, the tipping point
of your wheelchair is changed for the worse.
– Ensure that the bands are set correctly.
IMPORTANT!
– Do not overtighten the bands; this is to ensure
that the geometry of the wheelchair is not
changed.
IMPORTANT!
– Only ever tighten the bands when the
wheelchair is unfolded.
3.5.3 Backrest cover height
The backrest cover height can be adjusted for all backrest
types.
WARNING!
Risk of tipping
The hanging of additional load (back pack or
similar items) onto your wheelchair back posts can
affect the rearward stability of your wheelchair.
This can cause the chair to tip backwards causing
injury.
– Therefore, Invacare strongly recommend the
use of anti-tippers (available as an option) when
using your back posts with additional load (back
pack or similar items).
The height of the backrest cover can be adjusted on
the back posts. The adjustment must be carried out
by a qualified technician.
