FIRE PREVENTION AND EXPLOSION PREVENTION
Regeneration
The exhaust gas temperatures during regeneration will be elevated. Follow proper fire prevention
instructions and use the disable regeneration function when appropriate.
General
All fuels, most lubricants, and some coolant
mixtures are flammable.
To minimize the risk of fire or explosion, the
following actions are recommended.
Always perform a Walk-Around Inspection,
which may help you identify a fire hazard.
Do not operate a machine when a fire hazard
exists. Contact your dealer for service. 3001SH01
Understand the use of the primary exit and alternative exit on the machine.
Do not operate a machine with a fluid leak. Repair leaks and clean up fluids before resuming machine
operation. Fluids that are leaking or spilled onto hot surfaces or onto electrical components can cause a
fire. A fire may cause personal injury or death.
Do not weld on or drill holes in the engine cover. Flammable material such as leaves, twigs, papers,
trash may accumulate in engine compartment.
Remove flammable material such as leaves, twigs, papers, trash and so on. These items may
accumulate in the engine compartment or around other hot areas and hot parts on the machine.
Keep the access doors to major machine compartments closed and access doors in working condition
in order to permit the use of fire suppression equipment, in case a fire should occur.
Clean all accumulations of flammable materials such as fuel, oil, and debris from the machine.
Do not operate the machine near any flame.
Keep shields in place. Exhaust shields (if equipped) protect hot exhaust components from oil spray or
fuel spray in a break in a line, in a hose, or in a seal. Exhaust shields must be installed correctly.
Do not weld or flame cut on tanks or lines that contain flammable fluids or flammable material. Empty
and purge the lines and tanks. Then clean the lines and tanks with a nonflammable solvent prior to
welding or flame cutting. Ensure that the components are properly grounded in order to avoid unwanted
arcs.
Dust that is generated from repairing nonmetallic hoods or fenders may be flammable and/or explosive.
Repair such components in a ventilated area away from open flames or sparks. Use suitable Personal
Protection Equipment (PPE).
Inspect all lines and hoses for wear or deterioration. Replace damaged lines and hoses. The lines and
the hoses should have adequate support and secure clamps. Tighten all connections to the
recommended torque. Damage to the protective cover or insulation may provide fuel for fires.

9. OPERATION IN THE SPECIAL WORK SITES
1) OPERATION THE MACHINE A COLD WEATHER
(1) Use proper engine oil and fuel for the weather.
(2) Fill the required amount of antifreeze in the cool-
ant.
50 C
(3) Refer to the starting engine in cold weather.
Start the engine and extend the warming-up
operation.
(4) Be sure to open the heater cock when using the
heater.
(5) Always keep the battery completely charged.
侍 Discharged batteries will freeze more easily
than fully charged.
(6) Clean the machine and park on the wood plates. 740TM94OP16
2) OPERATION IN SANDY OR DUSTY WORK SITES
(1) Inspect air cleaner element frequently. Clean or
replace element more frequently, if warning
lamp comes ON and buzzer sounds simultane-
ously, regardless of inspection period.
(2) Inspect radiator frequently, and keep cooling fins
clean.
(3) Prevent sand or dust from getting into fuel tank
and hydraulic tank during refilling.
(4) Prevent sand or dust from penetrating into
hydraulic circuit by tightly closing breather cap of
hydraulic oil tank. Replace hydraulic oil filter fre-
quently.
(5) Keep all lubricated part, such as pins and bush-
ings, clean at all times.
(6) If the air conditioner and heater filters clogged,
the heating or cooling capacity will drop. Clean
or replace the filters more frequently.

6. TOWING THE MACHINE
Personal injury or death could result when tow-
ing a disabled machine incorrectly.
Block the machine to prevent movement before
releasing the brakes. The machine can roll free
if it is not blocked.
Except for an emergency, do not tow this
machine. If it is inevitable to tow this machine,
observe the following.
1) GENERAL
(1) Parking brake cylinder of the machine is operat-
ed by the spring force and released by hydraulic 1
pressure.
If the engine does not operate, the brake will be
operated to stop the machine.
(2) When the machine is towed move it for a repair
to nearby place at the speed less than 2 km/hr
(1.2 mph). Transport it on a trailer, if it has to be
moved for a long distance.
(3) When the steering device and the brake of the
machine to be towed can not be operated, trans-
port by trailer.
Be careful when towing.
Be careful that the brake will not work if there
is any disorder in the braking system.
(4) When you tow the machine from the front,
attach the tow line to the tow eyes on the front 2
frame (1).
When you tow the machine from the rear, use
the tow rear eyes provided for lift & tie (2).
(5) Do not use a chain for pulling a disabled
machine. A chain link can break. This may cause
personal injury. Use a wire rope cable with ends
that have loops or rings. Place an observer in a
safe position in order to watch the pulling proce-
dure. The observer can stop the procedure, if
necessary. The procedure should be stopped if
the cable starts to break. Also, stop the proce-
dure if the cable starts to unravel. Stop pulling
740TM95TA09
whenever the towing machine moves without
moving the towed machine.
