ATTENTION:
all lubrication and greasing operations must be performed without
persons on the work platform.
Climb onto the work platform and repeat the test with the controls on board. Check the
state of the power supply cable of the controls on the ground in the part under the
turret. If the cable is twisted, remove the plug from the turret control panel and untwist.
5.9.2 Outriggers and interlock end run
Before all use, check for the correct operation of all stabilisers/boom interlock limit
switches. To carry out correct functioning test, stabilise the machine and check boom
functioning. Lower the boom, retract the outriggers one at a time and check that the
boom does not operate.
5.9.3 Overload device in the work platform
The efficiency of this device must be tested before every use. Stabilise the machine
for testing. Position the key selector switch on the work platform controls, position a
load such to exceed the maximum capacity slightly. The alarm is triggered, the LED
switches-on on the controls, an acoustic warning is heard, the power supply LED on
the control board switches-off and the machine blocks.
The machine should function correctly when the extra load has been removed.
5.9.4 Load cell calibration procedure
The user calibration allows to acquire an offset (tare) to reset to zero the load reading.
This operation is only possible if the current read load value is between -10% and +
10% of the maximum load around the original zero.
This calibration is always possible, just follow the procedure given below:
