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

To turn the fork 

frontward 

Loosen

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.
