OPERATION INSTRUCTIONS
Note: Only the high exhaust temperature indicator
light in solid ON state indicates that the engine
is performing automatic after-treatment regenera-
tion, which takes about 25-30mins. After the regen-
eration is completed, the high exhaust temperature
indicator light will go out. (No movements will be af-
fected during the automatic regeneration process)
Cancel EAT Process
NOTICE
If the machine is shut down unexpectedly due to
engine failure, make sure to correct the failure before
restarting the engine.
Cancel EAT process immediately if:
• Ground/platform control selector switch is turned
from ground control position to platform control
position.
• Any movement switch is turned on.
• Engine is powered off.
If EAT process is interrupted, make sure to restart EAT
process afterwards.
EAT Failed
If EAT process is not completed within the specified
time, a red warning message will be displayed on the
EAT System Info interface, and the corresponding fault
indicator light will light up. In such case, you need to
contact the engine manufacturer to complete the EAT
process.
7.7 HYDRAULIC GENERATOR (IF
EQUIPPED)
1. Start the engine and wait for the engine to run at idle
speed stably.
2. Stop all the movements of the machine, depress the
foot switch and turn on the hydraulic generator
switch, and the engine will automatically start to run
at high speed, and after the engine runs at high
speed stably for 5s, the solenoid valve of the
hydraulic generator will be energized and start gen-
erating electricity.
7.8 TURNTABLE ROTATION
Before performing turntable rotation, make sure
that the boom is sufficiently distant from
surrounding walls, obstacles, etc.
Perform operation from the ground:
1. Rotate the turntable clockwise: Move and hold the
enable switch, pull down the turntable rotation
switch, and the turntable will rotate clockwise.
2. Rotate the turntable counterclockwise: Move and
hold the enable switch, push upward the turntable
rotation switch, and the turntable will rotate
counterclockwise.
Perform operation from the platform:
1. Rotate the turntable clockwise: Depress the foot
switch, push the main boom luffing/turntable rotation
control handle to the left, and the turntable will rotate
clockwise.
2. Rotate the turntable counterclockwise: Depress the
foot switch, push the main boom luffing/turntable ro-
tation control handle to the right, and the turntable
will rotate counterclockwise.
Note: When performing the operation from the platform,
the rotation speed of the turntable is in direct proportion
to the travel distance of the handle. The shorter the trav-
el distance, the slower the speed.
