5. Ensure that the base microswitch block the operation of
the brushes when the base is lifted a few centimetres from the
ground.
6. If necessary, adjust the blade of the microswitch.
7. Carry out a functional test to check that, with the base down,
the brushes begin turning when the machine is set for working
operation.
8. For the correct height of the base, check that the thread of the
stem protrudes about 5 mm. Ensure that the brushes can be
easily removed and that there is sufficient space for the
passage of the fastening buttons below the brush holder
plates. Otherwise act on the thread adjustment.
9. Check the adjustment of the base lowering limit switches
in order to give the correct pressure of the base to the ground.
Pay attention that in the event of excessive pressure, the
wheels may rise slightly.
10. Check that when lifting, the base does not touch the tank and
when lowering without brushes it does not touch the floor.
Otherwise, proceed as follows:
• Using a small screwdriver as a lever, remove the plastic
cover of the microswitches inside the jack;
• Loosen the screws holding the micro sliding them to
determine the correct position;
• Tighten the screws;
• Replace the plastic cover;
• Perform a functional test.
11. Adjust the belt-stretcher spring to a length of 27mm under
compression.
12. Adjust the transversal inclination of the base:
• position the machine on an even, flat floor
• lower the base onto the floor with the brushes assembled
• loosen the screw and M8 nut that fix the left lifting arm
to the base
• rest the base on the floor so that the brushes touch the
floor simultaneously
• tighten the M8 screw and the locknut
