components.
Components containing asbestos should be handled
in accordance with applicable regulations and industry
practice.
20. Do not open high-pressure fuel system. High-pressure
fluid remaining in fuel lines can cause serious injury.
Do not disconnect nor attempt to repair fuel lines,
sensors, or any other components between the high-
pressure fuel pump and injectors on engines with high-
pressure common rail fuel system.
21. To avoid hazardous high voltage, turn the key switch
to the OFF position if it is necessary to check to repair
the computer, harness or connectors.
22. For proceeding to regenerate the DPF, a warning
indicator appears on the LCD display to tell you to
increase the engine rpm to its specified level. Follow
that instruction.
23. When the Diesel Particulate Filter (DPF) is in the
regenerating cycle, the exhaust gas and the DPF
muffler become hot. During regeneration, take into
account that the muffler will be very hot and keep the
machine away from other people, animals, plants, and
flammable material. Also keep the area near the DPF
muffler clean and away from flammable material.
24. The DPF-regeneration-caused exhaust gas may
adversely affect people, animals and plants. Before
this action, look around the machine for added safety.
25. During DPF regeneration keep the surrounding
environment in mind. Do not allow the ambient
temperature to rise excessively due to heat from the
regeneration. If such occurs activate the inhibit switch.
26. Fire prevention
Excavator and some attachments have components
that are at high temperatures under normal operating
conditions. The primary source of high temperatures is
the engine and exhaust system. The electrical system,
if damaged or incorrectly maintained, can be a source
of arcing or sparks.
The following fire prevention guidelines will help to
keep your equipment up and running efficiently and
keep the risk of fire to a minimum.
A Blow off all accumulated debris near hot engine
exhaust components such as turbocharger and
exhaust manifold as well as exhaust pipes and muffler
more frequently when working in severe conditions.
A Clean out all accumulated flammable debris such as
leaves, straw, pine needles, branches, bark, small
wood chips and any other combustible materials from
inside the machine belly pans or lower unit structures
as well as from area in proximity to the engine.
A Inspect all fuel lines and hydraulic hoses for wear or for
deterioration. Replace them immediately if they begin
to leak.

A Examine electrical wiring and connectors frequently
for damage. Repair any wires that are loose or frayed
before operating the machine. Clean all electrical
connections and tighten all electrical connections as
necessary.
A Inspect the exhaust system daily for any signs of
leakage. Check for broken pipes and muffler and also
for loose or missing bolts, nuts and clamps. If any
exhaust leaks or fractured parts are found, repairs
must be completed prior to operation.
A Always keep a multipurpose fire extinguisher on or
near the machine. Be familiar with the operation of the
fire extinguisher.
