OPERATING THE ENGINE
WARNING
To avoid personal injury or death:
• Read and understand the safe operation
section.
• 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 the
ground. Start the engine only from operator's
seat.
• Make it a rule to set all shift levers to the
“NEUTRAL” positions and to place PTO clutch
control switch in “OFF” position before starting
the engine.
Details regarding safe operation can be found in a
different section.
(See SAFE OPERATION on page 7.)
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 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 tractor away from people, animals or
structures which may be susceptible to harm or
damage from hot exhaust gases.
• During regeneration, white exhaust gases may
be visible. Do not allow regeneration in an
unventilated garage or confined area.
• During regeneration, do not leave the tractor.
NOTE :
• Exhaust aftertreatment devices vary depending
on the model. In accordance with the following
table, refer to the appropriate item.
Model Exhaust aftertreatment device
M4N-071 DPF muffler only
M5N-091
M5N-111
DPF and SCR muffler
1. Dual exhaust aftertreatment
devices
Particulate matter (PM) and black smoke contained in
exhaust gases are trapped and removed by the diesel
particulate filter (DPF) muffler.
The SCR system then decomposes residual nitrogen
oxides (NO
x
) into harmless nitrogen (N
2
) and water
(H
2
O) for purification.
This dual exhaust gas purifying device provides for
clean exhaust gas at low fuel consumption.
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 diesel engine emissions, to
harmless carbon dioxide and water. The DPF also traps
particulate matter (PM).
Please handle exhaust aftertreatment devices correctly
and in an environmentally responsible manner.
