Make sure to check the platform floor area, as
inspection of this area may uncover conditions that
could cause personal injury or machine damage.
5.4 FUNCTIONAL TEST
Before performing a functional test:
• Choose a firm, flat and level test area.
• Make sure the test area is free from obstructions.
For telescopic booms with three or more stages,
when checking the telescoping function of the
boom, ensure that all boom sections extend/
retract together at the same speed. If any anomaly
is observed, it could indicate potential movement
delays and loosening of the wire ropes. In such a
case immediately lower the platform to the
stowed position, turn off the machine, and have
the wire rope inspected and repaired by a
qualified service technician.
If any switch/handle returns to neutral position
and the corresponding movement does not stop,
remove the foot from the foot switch or push in
the emergency stop button to stop the machine.
NOTICE
• When the auxiliary power is in use, do not perform
two or more functions at the same time, because
certain operations may not respond due to the low
voltage in the auxiliary motor or pump.
• The auxiliary power switch can only be used for a
short time (to fully lower and retract the platform
from maximum angle/maximum extension) when
the main power source is not working, prolonged
operation may damage the motor.
Follow these steps to perform a functional test:
1. With no load applied on the platform, turn the
ground/platform control selector switch on the
ground controls to the ground control position, pull
out the emergency stop button on the ground con-
trols, and perform the following tests from the
ground controls:
1) Make sure that the relevant indicator lights on
the display illuminate and that no error or alarm
message is displayed during the entire functional
test.
2) Make sure that when the emergency stop button
on the ground controls is pressed, the controls
are powered off, the machine cannot be started
and no functions can operate.
3) Make sure that the horn sounds properly when
the horn button is pressed.
4) Activate the engine start switch – the engine
should start smoothly without abnormal noise (if
the machine is equipped with an engine).
