PRE-OPERATION INSPECTION
5) Activate any action switch without activating the
enable switch, the corresponding function must
not operate.
6) Activate the enable switch and any action switch
at the same time, the corresponding function
should operate normally.
7) Withthemain power source turned off, activate
the emergency power switch and any boom ac-
tion switch at the same time – the corresponding
function shall operate normally. After that, deac-
tivate the emergency power(This test is required
if the machine is equipped with an emergency
power switch).
2. Turn the ground/platform control selector switch on
the ground controls to the platform control position,
pull out the emergency stop button on the ground
controls and platform controls, and perform the fol-
lowing tests from the platform controls:
1) Make sure that when the emergency stop button
on the platform controller is pressed, the plat-
form controller is powered off and no function on
the platform controller can be activated.
2) Make sure that the horn sounds properly when
the horn button is pressed.
3) Activate the engine start switch – the engine
should start smoothly without abnormal noise (if
the machine is equipped with an engine).
4) Activate any action switch/handle without de-
pressing the foot switch – the corresponding ac-
tion will not operate.
5) Depress the foot switch and activate any action
switch/handle at the same time – the corre-
sponding action shall operate normally. Move
the switch/handle to the neutral position after an
action is performed; the corresponding action
should stop reliably and safely.
Note: When the travel function handle is re-
leased, the brake must be able to hold the ma-
chine on any slope within the maximum
gradeability reliably without sliding.
6) Move any action switch/handle 7 secs after the
foot switch is depressed – the corresponding ac-
tion must not operate and the buzzer will sound.
7) When the boom rotates beyond the rear wheels,
the rear position indicator light should flash and
the travel function should be deactivated. After
pressing the rear position travel drive switch, the
rear position indicator light Should illuminate
steadily, and the travel function should be
reactivated.
In this case, the direction of travel and
steering of the machine will be opposite to
the indicated direction. Operate the ma-
chine with caution!
8) With the machine in non-operating position,
push the high/low drive speed selector switch
upward – the machine will start to run at high
speed. Push the travel control handle to the full
drive position – the machine will travel at the
maximum travel speed.
9) With the machine in operating position, push the
high/low drive speed selector switch upward –
the machine will start to run at low speed. Push
the travel control handle to the full drive position
–the machine continues to travel at low speed.
10) When the machine travels on a slope with a
grade greater than or equal to the maximum al-
lowable tilt angle of the machine and smaller
than or equal to the maximum gradeability of the
machine, the chassis tilt indicator icon will illumi-
nate, and the tilt alarm will be triggered.
11) Without activating the main power source, de-
press the foot switch, and activate the emer-
gency power button and any boom action switch
at the same time – the corresponding action
should operatenormally. After that, deactivate
the emergency power(This test is required if the
machine is equipped with an emergency power
switch).
