OPERATING THE ENGINE
WARNING
To avoid personal injury or death:
• Read and understand Safe operation in the front
of this manual.
• Read and understand the safety labels located
on the tractor.
• To avoid the danger of exhaust-fume-poisoning,
do not operate the engine in a closed building
without proper ventilation.
• Never start the engine while standing on
ground. Start the engine only from the
operator's seat.
• Always set all shift levers to the “NEUTRAL”
positions and to place the PTO-clutch-control-
switch in the “OFF” position before starting the
engine.
(See PRECAUTIONS FOR OPERATING THE
TRACTOR on page 8, PRECAUTIONS FOR PARKING
THE TRACTOR on page 11, and PRECAUTIONS FOR
SERVICING THE TRACTOR on page 12)
IMPORTANT :
• Do not use starting fluid or ether.
• To protect the battery and the starter, make sure
that the starter is not continuously turned for
more than 10 seconds.
EXHAUST AFTERTREATMENT
DEVICES
WARNING
To avoid personal injury or death:
• During the diesel-particulate-filter (DPF)
regenerating operations, exhaust gases and
exhaust filter components reach temperatures
hot enough to burn people, or ignite or melt
common materials.
• Keep the tractor away from people, animals, or
structures which may be susceptible to harm or
damage from hot exhaust gases.
• During the regeneration, white exhaust gases
may be visible. Do not allow the regeneration in
a non ventilated garage or confined area.
• During regeneration, do not leave the tractor.
1. Diesel particulate filter (DPF)
muffler
This tractor is equipped with an engine with a diesel-
particulate-filter (DPF) muffler which serves to reduce
hydrocarbons, carbon monoxide, and other toxic gases,
all of which are contained in emissions of the diesel
engine, to harmless carbon dioxide and water. The
DPF also traps particulate matter (PM).
Please handle the exhaust aftertreatment devices
correctly and in an environmentally responsible
manner.
(1) Diesel particulate filter (DPF)
2. Handling points for DPF
regeneration
When a specific amount of particulate matter (PM) has
accumulated in the DPF muffler, it is necessary to
refresh the DPF muffler by burning the PM inside it.
This burning off work is called
“Regeneration” .
To extend the operating time to reach this regeneration,
and to avoid DPF muffler trouble, make sure to follow
the following handling matters.
Fuel
Be sure to use the ultra low sulfur fuel (S15).
IMPORTANT :
• Use of diesel fuel other than ultra low sulfur fuel
may adversely affect the engine and DPF
performance.
Use of fuels other than ultra low sulfur fuel
(S15) may not meet regulations for your region.
Engine oil
Use the DPF-compatible oil (CJ-4) for the engine.
