Things You Should Know for Safe Operation

• Inspection and Maintenance

CAUTION .&.• Inspections should normally be performed when the engine is not

running. If you must perform an inspection while the engine isrunning for unavoidable reasons, be careful not to touch its movingparts.

• The engine is always hot immediately after being stopped. Be carefulnot to burn yourself. Whenever possible, inspections should beperformed when the engine is cold.

• After performing inspections or maintenance, make sure you do notleave rags or tools in the engine compartment. Flammable itemscould catch fire during engine operation.

E0326

WARNING .&.Always operate the engine in a well ventilated place. Operation ofthe engine in a poorly ventilated place can result in a poisonousbuildup of exhaust gases.

E0250

Always wear appropriateclothing and use toolscorrectly.

Before inspectingelectrical components,turn OFF the batteryswitch or disconnectthe (-) terminal ofthe battery.

-2-

In the event of an emergencyengine shutdown, identity andrectify the abnormality beforerestarting the engine.

o

E0057

CAUTION .&.The engine is hot immediately after beingstopped. Be careful not to bum yourself whenperforming inspections.

• Operation of New Engine

During your engine's running-in period(the first 60hours ofoperation),• Donot rev theengine;• Allow theengine to warm upfully before operation;• Make every effort to avoid overloading theengine.

The engine and transmission oils willdeteriorate rapidly during the running-inperiod. Thus, the oils must be replacedafter the following operation hourshave reached:Engineoil: first 60 hoursTransmission oil: first 250 hours

EOOO3

• Battery

DANGER .&.The battery emits explosive hydrogen gas.Never use naked flames or performoperations that may create sparks near thebattery.

WARNING .&.If battery fluid splashes in your eyes,immediately wash it out with plenty ofwater and seek medical attention.

CAUTION .&.Battery fluid contains sulfuric acid, so it canbum the skin and make holes in clothing ifspilled. Always handle battery fluid carefullyand wash away any spilled fluid with soap andplenty of water.

CAUTION .&.

• ASTM: American Society for Testing Materials.The ASTM recommends the usa of fuel with asulfur content of 0.5% or less. The use of fuelwith a sulfur content exceeding 0.5% shortensthe engine oil replacement interval by 50%.

• Fuel

Use only diesel fuel, without any compound,for the diesel engine.

WARNING .&.Never use gasoline or alcohol. If gasoline oralcohol is put into the fuel tankaccidentally, it must be completely drainedfrom the fuel system. Operation of theengine with gasoline or alcohol in the fuelsystem could cause a fire or explosion.

CAUTION .&.Always stop the engine before refueling it.Never smoke or use a lighter or other nakedflame while filling the fuel tank.

Fuel-Related Precautions

• After filling a fuel storage tank, allow 24 hoursfor dirt and water to sink to the bottom.

• Always refill the engine's fuel tank completelyafter engine operation. By minimizing theamount of air in the fuel tank, this reduces thelikelihood of moisture (the air's water content)freezing and causing corrosion and startingdifficulties.

• When refueling the engine from a storagetank, be careful not to draw up sediment fromthe bottom of the tank.

• To prevent dirt and water from entering thefuel storage tank and the engine's fuel tank, fitthe caps securely when refueling is complete.Periodically allow dirt and water to escape viathe drain plug at the bottom of each tank.

Simple Inspection and Maintenance

• Safety Precautions

This chapter contains easy-to-follow instructionsfor inspections and maintenance operations youcan do yourself.

CAUTION &

Improper adjustments can detract from theengine's performance and can cause theengine to pollute the environment by emittingblack smoke and excessive exhaust gases.

WARNING &Always operate the engine in a wellventilated place. Operation of the engine ina poorly ventilated place can result in apoisonous buildup of exhaust gases.

E0326

Always wear appropriateclothing and use toolscorrectly.

Before inspecting electrical components,

stop the engine, then turn OFF the batteryswitch or disconnect the (-) terminal ofthe battery.

E0327

NOTE• Maintenance and inspection intervals should

be shortened if the engine operates underparticularly severe conditions.

• The engine's fuel injection pump was adjustedfor optimal operation before leaving thefactory. Under no circumstances tamper withits seal and/or attempt to make adjustments.

• Inspections should normally be performedwhen the engine is not running. If you mustperform an inspection while the engine isrunning for unavoidable reasons, be carefulnot to touch its moving parts.

• The engine is always hot immediately afterbeing stopped. Be careful not to bumyourself. Whenever possible, inspectionsshould be performed when the engine iscold.

• After performing inspections ormaintenance, make sure you do not leaverags or tools in the engine compartment.Flammable items could catch fire duringengine operation.

-54-

• Inspection of Exhaust Color

Let the enginewarm up fullybefore inspecting the exhaustgas color. ~__-_-

E0035

Colorless/pale blue:NormalBlack Bad (indicates incomplete

combustion)White Bad (indicates that oil is leaking

past piston rings and burning incombustion chambers)

In the winter months, low temperatures maymake the exhaust gases appear white evenwhen the engine is operating normally.

• Battery Maintenance

DANGER .&The battery emits explosive hydrogen gas.Never use naked flames or performoperations that may create sparks near thebattery.

WARNING .&If battery fluid splashes in your eyes,immediately wash it out with plenty ofwater and seek medical attention.

CAUTION .&

• Battery fluid contains sulfuric acid, so it canburn the skin and make holes in clothing ifspilled. Always handle battery fluidcarefully and wash away any spilled fluidwith soap and plenty of water.

• Do not use the battery with the fluid levelbelow the LOWER level line. Doing sowould shorten the battery's service life andcould cause the battery to overheat andexplode.

• Store any used battery with its terminals atthe top. Storing the battery on its sidecould result in fluid leakage and in a fire.


Inspect and top up the battery fluidevery 125 hours or two weeks

(once a week in summer).

Acceptable rangeA5574

The fluid level should be between the UPPERand LOWER level lines or 10 to 15 mm (0.39 to0.59 in) above the plates.Some types of battery have only one level line.In this case, the line indicates the LOWER level.

-55-


10to15mm(0.39 to 0.59 in)-------------

A55?5

If the fluid level is too low, remove the caps andtop up the fluid with electrolyte or distilled water.

NOTE• Do not allow the fluid level to rise above the

UPPER level line or rise more than 15 mm(0.59 in) above the plates.

• Top up the fluid before charging the battery orrunning the engine. Note that in winter thefluid can freeze and damage the battery whenits specific gravity is low.

• Before inspecting/maintaining the battery orinspecting electrical components, stop theengine, then turn OFF the battery switch ordisconnect the (-) terminal of the battery.

• Remove the battery from the machine beforecharging it.

-56-

Clean the battery terminals every 250 hours.

A55??

• Make sure the caps are tightened securely onthe ports to prevent foreign matter fromentering the battery case.

• Remove any dirt from the terminals.• If the terminals are contaminated by white

powder (this indicates corrosion), clean themwith warm water. If the corrosion is severe,disconnect the battery cables and rub theterminals with sandpaper or a wire brush.

• Lightly smear the terminals with grease aftercleaning them.

NOTEWhen disconnecting the battery cables,disconnect the (-) cable first. When reconnectingthe cables, connect the (+) cable first.It is dangerous to have only the (-) battery cableconnected since sparks could be produced if atool or other metal object short-circuited the (+)terminal to the frame.

• Replacement of PreheatingCircuit Fuse

CAUTION .&.

Use a Mitsubishi genuine replacement fuse ofthe specified amperage. A fuse with adifferent amperage could cause a fire.

For safety, the air heater relay in the enginepreheating circuit is fitted with a fuse. If thepreheating indicator fails to glow red, checkwhether the fuse has blown.In the event that the fuse blows, rectify the faultand replace the fuse with a new one.

NOTEBefore replacing the fuse, stop the engine, thenturn OFF the battery switch or disconnect the (-)terminal of the battery.

• Cleaning and Replacement of Air Cleaner Element

Inspect and clean the elementEvery 250 hours and whenever the red signal appears in the dustindicator. (With a double-element air filter, only the outer element canbe inspected and cleaned.)

Replace the elementCyclone and cartridge type: Every 1,000 hours(With a double-element air filter, replace the outer and inner elementsat the same time.)

Cyclone (Single-Element) Type


NOTE• Shorten the inspection/cleaning and replacement intervals if the engine

is used in a particularly dusty environment.• It is not possible to clean and reuse the inner element of a double

• Since FUSO ANTIFREEZE has anticorrosionproperties, no additional corrosion inhibitor isrequired.

• Use FUSO ANTIFREEZE at a concentrationof 30% to 60%. At a concentration below30%, Fuso Antifreeze does not preventcorrosion effectively, and at a concentrationexceeding 60% it does not effectively preventthe coolant from freezing.

• When the ambient temperature is highenough that there is no risk of the coolantfreezing, replace coolant containingantifreeze with coolant containing a corrosioninhibitor. In warm weather, the use of coolantcontaining antifreeze makes the engine proneto overheating.

CAUTION .&Remember that the coolant replacementinterval depends upon the additive used.

Remove the radiator cap and top up the coolantuntil it reaches the bottom of the opening.

Adding Coolant

WARNING .&Do not open the radiator cap until thecoolant temperature has dropped. Whenremoving the radiator cap, cover the capwith a cloth and turn it slowly. Unless thecap is opened carefully, boiling coolant andsteam could spray out and scald you.

NOTE• If the coolant in the system contains antifreeze,

a corrosion inhibitor, or longlife coolant, makesure the additional coolant contains the sameadditive in the same concentration. Theaddition of plain water would simply dilute thecoolant in the system, resulting in lessprotection against freezing and corrosion.
