3.4 ADJUSTING AND FASTENING
PERMANENTLY
In order for it to work correctly, the rack must never
rest on the pinion.
1. Lower the gearmotor: turn the 4 support nuts
clockwise by half a turn (a constant distance (A)
between pinion and rack is constant for the entire
length of travel.
2. Carry out the following checks (move the leaf
manually to check the entire length of travel and
all the elements of the rack).
- Distance (A): with the gearmotor locked, it must be
possible to rock the leaf manually to the left and
right by a few millimetres.
- Gearmotor levelling: use a spirit level.
- Centring (B) of the rack and pinion.
3. Tighten the upper nuts to the fastening torques
indicated in the figure.
4. Press the guards onto the brackets.
