SERVICE MANUAL
It is advisable to pread a
drop of mild lock thread
glue on all grab screws
G .
WORK ON A FLAT AND EVEN SURFACE
Whenever the seat height is changed or as periodic maintenance, check the fork angle and, if necessary, adjust it in order to have the fork
axis perpendicular to the ground.
The adjustment is possible by means of the four grab screws G1 , G2 and G3 that make the axle P turn on the fulcrum F .

Perpendicularity
You can check the perpendicu-
larity with the help of a square
(or similar) vertically aligned to
the caster turned 90° with re-
spect to the driving direction of
the wheelchair
To turn the fork
backward
Loosen G1 and G3
Screw G2
To adjust the fork, once you know the direction (frontward or backward) towards which it is necessary to move the fork’s axle, proceed as
above-mentioned until reaching the correct angle.
You can also measure the perpendicularity by turning the fork by 360°: during the full turn, the wheel has to touch the surface in all posi-
tions.
If a headless bolt results hard to unscrew, DO NOT FORCE IT, but try to loosen the other two first.
If the fork’s axle (the axle P ) results hard to move, slightly loosen the bolt of the fulcrum F (remember to screw it after adjust-
ment).
Once you reach the correct angle, screw all three headless bolts all the way down to the axle P , but without tightening.
In order to fix the system, tighten first one and then the other less than a quarter of a turn at once, the grab screws G1 and G2 (the front
ones) checking the perpendicularity; in fact, it may slightly change during this phase.
Should that happen, correct the angle proceeding in the same manner.
When you have tightened both headless bolts G1 and G2 , you can tighten the headless bolt G3 .
Check the perpendicularity again and, if necessary, correct it.
