OPERATION OF THE ENGINE
PRECAUTIONS FOR
OPERA
TING THE ENGINE
WARNING
T
o avoid personal injury or death:
• To avoid the danger of exhaust fumes (carbon
monoxide) poisoning, do not operate the
machine in a closed building or any closed area
without proper ventilation.
• Always start the engine from the operator's
seat. Do not start the engine while standing
next to the machine. Before starting the engine,
sound the horn to get the attention of persons
standing nearby.
(1) Horn switch
IMPORTANT :
• Do not use starting fluid or ether.
• In order not to overload the battery and starter,
avoid start-ups of more than 10 sec.
• When the engine does not start in 10 sec.,
please wait 20 sec. or more, before restarting.
EXHAUST AFTERTREATMENT
DEVICES
WARNING
T
o 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 machine 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 the regeneration in a
non ventilated garage or confined area.
• During regeneration, do not leave the machine.
1. Diesel oxidation catalyst and
diesel particulate filter (DPF) muffler
The diesel-oxidation-catalyst and diesel-particular-filter
(Hereinafter
called DPF) 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).
To meet the emission regulations in your country, the
DPF is installed on your wheel loader.
Be sure to read this operator's manual before running
in your machine.
It is imperative for the machine owner and operator to
handle the DPF in a safe and environmentally
responsible manner.
(1) Diesel particulate filter (DPF)
NOTE :
• When
the DPF has trapped a specific amount of
particulate matter (PM), the engine computer
starts the process of regeneration or burning of
soot collected by the filter.
This burning process is called regeneration.
