Wheel Alignment - Zippie Simba Notice D'utilisation

Wheel Alignment

Adjusting the wheel alignment
Important: To achieve the very best movement, the rear wheels must be
adjusted to their optimum position, which means correctly adjusting the wheel
alignment.
To do this, measure the distance between both wheels front and rear to
ensure that they are parallel to one another. The difference between both
measurements should not exceed 5 mm.
To adjust the wheels to make them parallel, loosen the screws and turn the
axle sleeve accordingly. Make sure that after any adjustment work, all screws
are tightened correctly (see the page on torque).

Setting the toe-in/toe-out to zero:
NOTE: A wheelchair with 0° camber cylinders cannot have toe-in or toe-out.
This setting is necessary only with 3°, 6° and 9° camber cylinders.
The term "toe-in or toe-out" defines how well the rear wheels of the chair are
aligned in relation to the ground. This determines how well the chair will run.
Normal resistance or rolling resistance is present when toe-in is set to zero.
To set toe-in/toe-out to zero: Loosen the Allen screws (1) (one on each side),
which secure the angle tube clamp. Check the ball in the horizontal (2) plane
and turn the angle tube (3) until the ball is in the centre. Toe-in is now zero.
Before tightening the screws (1), check that the camber tube is centred left-
to-right. The gap should be the same on both sides, or there should be no
gap at all. Tighten the screws to 10 Nm (Fig. 5.14 - 5.16).
Adjusting the wheelbase width
CAUTION!
When adjusting the rear wheelbase, adjust first one wheel then the other.
If both sides are loosened at the same time, this will alter the toe-in/toe-out
adjustment. To adjust the rear wheelbase, the parts of the camber (4) move
telescopically into or out of the camber tube (5), and lock into place when
they reach the end. Loosen screw (6) (located closest to the camber tube) on
the left side of the chair.
Move the quick-release axle inwards or outwards to achieve the desired
wheelbase. Tighten the screws to 10 Nm. Repeat this procedure on the right
side of the chair and adjust the gap so that it is the same amount as on the
left side (Fig. 5.17).
CAUTION!
The screws/bolts used on this wheelchair have thread locking fluid applied at
the factory. After that they should be replaced or alternatively re-secured with
threadlock to medium tightness.
