reduce nitrogen oxides (NOx) in exhaust emissions, and Diesel Exhaust Fluid (DEF) is used as
a reducing agent.
Use DEF that is compliant with the ISO (International Organization for Standardization) 22241
standard defined for AUS 32, or theAPI (American Petroleum Institute) standards.
WARNING : INJURY
Do not open the check door when the starter switch is in the AUTO or START position.
It will cause injury by rotating parts such as cooling fans and fan belt.
Always turn the starter switch to the STOP position and stop the engine, then close
and lock OPERATION PANEL DOOR before checking or maintaining the engine or
any equipment.
CAUTION : BURNS
Do not touch the engine and surrounding components immediately after stopping the
engine as they are still extremely hot.
While the engine is running, the SCR system is purging, and immediately after
operating, the SCR system and exhaust piping is extremely hot. Be careful not to
inadvertently touch them.

DEF, or other similar urea fluids, may be calledAdBlue depending on region.
AdBlue is a registered trademark of Verband der Automobilindustrie (VDA).
This generator is equipped with the SCR SYSTEM MONITER.
The indicator lights up according to the control operation of the SCR system.
(1) DEF LEVEL
It shows the amount of DEF in the tank.
All lamps are lit when the amount reaches to the maximum level, and FULL is lit.
The lit lamp decreases as the amount of DEF in the tank reaches to EMPTY.
< Note >
The engine will shut down upon DEF gets empty.
When replenishing diesel fuel, check the amount of DEF in the tank, and replenish DEF as
necessary.

(2) PURGE Indicator
After certain length of operation time, SCR system automatically increase the temperature of
the exhaust gas, and purges inside the system, thereby maintaining the system function.
This lamp is lit up during purging.
PERIODIC PURGE
Purge runs automatically after certain period of operating time. PERIODIC PURGE is lit
during operation.

FORCE PURGE
Purge forcibly runs in case that PERIODIC PURGE fails twice. FORCE PURGE is lit during
operation.
< Note >
During purging, electrical output capacity decreases to 80% of the rated output. Available
output capacity can be confirmed by Available Output Monitor.
FORCE PURGE failure does not stop the engine. Instead, the engine warning lamp will be lit.
In this case, contact distributor or dealer and ask for repair.
White smoke may be temporarily seen from the tailpipe during purging, but it is not a sign of
malfunction.
Smell of ammonia may be noticed during purging, but it is not a sign of malfunction.

(3) DEF Indicator
This lamp is lit or starts blinking to alert an error relating to SCR system which includes shortfall
of DEF, using DEF of low-quality, or disconnection of sensors.
Warning status ranges from stage-Ⅰto stage-Ⅲ. The engine will shut down at stage-3. In this
case, conduct inspection and repair immediately.
However, in case that you need restart the engine for unavoidable reasons, ESCAPE MODE
allows you to restart the engine for total time up to 30 minutes.
REFILL DEF
It is lit when the amount of DEF decreases to 10% or less.
Replenish DEF when it is lit.
EXH. SYSTEM
It lights up when abnormality of SCR System is detected.
Please contact distributor or dealer for repair.
ESCAPE MODE
It is lit when ESCAPE MODE is engaged.
(Refer to section "5-5. (4) Operating Escape Mode")
NO POWER (SHUTDOWN)
It is lit when the engine stops due to DEF shortfall or SCR system error.
Contact the authorized distributor where the generator was purchased.
