About Aftertreatment Device
The aftertreatment device removes particulate matter (PM)
and NOx (Nitrogen Oxide) from the exhaust gas. Follow the
instructions below to prevent the aftertreatment device
from being damaged.

WARNING: Exhaust gas from the aftertreatment
device, muffler, exhaust piping and tail piping
becomes hot during and right after engine running
and regeneration of aftertreatment device. Keep away
from the exhaust system or hot gas from the exhaust
piping during regeneration. Be careful to avoid skin
contact with exhaust gas. It may cause severe burns.
 White smoke may be generated during aftertreatment
device regeneration. Do not attempt to perform
aftertreatment device manual regeneration in a badly
ventilated area.
 Ammonia odor may occur during aftertreatment device
regeneration temporarily, but is not a trouble.
 Do not touch water coming directly out of the
aftertreatment device. The water is mildly-acidic by
oxidation catalyst mounted in the aftertreatment device.
If filter water spills on your skin, immediately flush it out
with clean water.

Precautions for Communication Terminal

 Electrical wave transmitted from the communication
terminal may cause malfunction of other electronic devices.
Inquire to the device manufacturer for information on
electrical wave disturbance when using an electronic device
near the communication terminal.
 Never attempt to disassemble, repair, modify or displace
the communication terminal, antennas or cables. Failure to
do so may result in damage and/or fire to the base machine
or to the communication terminal. (When required to
remove or install the communication terminal, consult your
authorized dealer.)
 Do not pinch or forcibly pull cables, cords or connectors.
Failure to do so may cause a short or broken circuit that may
result in damage and/or fire to the base machine or to the
communication terminal.
