The operations described in this section are fundamentally important
to the integrity and operation of the gearmotor.
1. When you have installed the rack, lower the gearmotor
by 1.5mm (26-1), by adjusting the four support nuts
(27-1).
2. Check that the gearmotor is level using a spirit level (27).
3. Tighten the four upper lock nuts to a minimum torque of 40Nm
(27-2), using a hex spanner and a torque wrench.
4. Move the gate by hand and check that:
- There is 1.5 mm between the teeth of the rack and pinion along
the travel
- The rack remains engaged with the pinion along its travel
(26-2)
- The leaf and gearmotor do not touch at any point
- There is no friction.
