8.2.1 Cleaning the machine and adhesive plates.
To clean the machine properly, you can use non-pressurized water jets, adequately protecting the
following details:
- Electrical components;
- Ground control panel and console;
- Electric motor (if present).
After cleaning the machine, dry all the details, check the integrity of the adhesive plates and grease the
areas with grease nipples or the sliding pads of the telescopic appendages of the arms and stabilizers.
Warning: Never use gasoline, solvents or other flammable liquids as cleaning agents. Use non-flammable
and non-toxic authorized commercial degreasers.
8.2.2 Functional checks.
According to the periodicity described in the maintenance table, and always before each use of the
machine, it is necessary to check the correct operation of the controls and the emergency stops. In
particular, the checks to be carried out are the following:
- With the platform in the transport position, activate the carriage widening command to check the
correct functioning of the system;
- With the platform in transport configuration, position the machine with the fifth wheel tilted with
respect to the horizontal by a value greater than 1° laterally. Activate any command on the aerial
part and make sure that the system automatically returns the fifth wheel plane to horizontal;
- With the platform in transport configuration, position the machine with the fifth wheel inclined
with respect to the horizontal by a value greater than 1° longitudinally. Activate any command
on the aerial part and make sure that the system automatically returns the fifth wheel plane to
horizontal;
- With the platform in transport configuration, position the machine with the fifth wheel tilted with
respect to the horizontal at the maximum angle both longitudinally and laterally. Activate any
command on the aerial part and make sure that the system automatically returns the fifth wheel
plane horizontal;
- With perfectly stabilized machine:
o Raise and lower the main arm and make sure that the machine works correctly (the
levelling of the platform is an automatic movement, check the correct functioning). There
must be no load on the platform.
o Perform the extension and retraction manoeuvre and make sure that the machine works
correctly. There must be no load on the platform;
o Raise and lower the JIB and make sure the machine is working properly. There must be no
load on the platform;
o Carry out the basket rotation manoeuvre in both directions and make sure that the machine
works correctly. There must be no load on the platform;
o Carry out the column rotation manoeuvre in both directions and make sure that the
machine works correctly. There must be no load on the platform;
- Lift the platform to a height higher than the TRANSPORT position but lower than the maximum
translation position and move on uneven ground, check that the machine stops automatically when
the inclination of the frame with respect to the horizontal exceeds 1°. Release the translation
control, at the next translation or lifting command the system must automatically return the fifth
wheel plane to horizontal. At the end of the levelling the machine carries out the selected
movement;
- Raise the platform to a height higher than the TRANSPORT position and check that the manual
levelling control of the fifth wheel plane is automatically inhibited. In the same situation, the lane
widening / narrowing command must also be inhibited.
