SEPTEMBER 2003
When the coolant level drops due to evaporation, add water
only to keep the anti ---freeze mixing ratio less than 50%. In case
of leakage, add anti ---freeze and water in the specified mixing
ratio before filling into the radiator.
Anti ---freeze absorbs moisture. Keep unused antifreeze in a
tightly sealed container.
Do not use radiator cleaning agents when anti ---freeze has been
added to the coolant. (Anti ---freeze contains an anti ---corrosive
agent, which will react with the radiator cleaning agent forming
sludge which will affect the engine parts.)
G. Radiator Cement
As the radiator is solidly constructed, there is little possibility of
water leakage. Should this happen, however, radiator cement
can easily fix it. If leakage is serious, contact your local
Ingersoll---Rand dealer.

Periodic Service
A. Fuel
Fuel is flammable and can be dangerous. You should handle fuel
with care.
CAUTION
DO NOT MIX GASOLINE OR ALCOHOL WITH DIESEL FUEL.
THIS MIXTURE CAN CAUSE AN EXPLOSION.
BE CAREFUL NOT TO SPILL FUEL DURING REFUELING. IF
FUEL SHOULD SPILL, WIPE IT OFF AT ONCE, OR IT MAY
CAUSE A FIRE.
DO NOT FAIL TO STOP THE ENGINE BEFORE REFUELING.
KEEP THE ENGINE AWAY FROM THE FIRE.
BE SURE TO STOP THE ENGINE WHILE REFUELING OR
BLEEDING AND WHEN CLEANING OR CHANGING FUEL
FILTER OR FUEL PIPES. DO NOT SMOKE WHEN WORKING
AROUND THE BATTERY OR WHEN REFUELING.
CHECK THE ABOVE FUEL SYSTEMS AT A WELL
VENTILATED AND WIDE PLACE.
WHEN FUEL AND LUBRICANT ARE SPILLED, REFUEL AFTER
LETTING THE ENGINE COOL OFF.
ALWAYS KEEP SPILLED FUEL AND LUBRICANT AWAY FROM
ENGINE.
B. Fuel Level Check And Refueling
(1.) Check to see that the fuel level is above the lower limit of the
fuel level gauge.
(2.) If the fuel is too low, add fuel to the upper limit. Do not overfill.
No.2---D is a distillate diesel fuel of lower volatility for engines in
industrial and heavy mobile service.

The cetane number is required not to be less than 45

NOTE
Be sure to use a strainer when filling the fuel tank, or dirt or
sand in the fuel may cause trouble in the fuel injection pump.
For fuel, always use diesel fuel. You are required not to use
alternative fuel, because its quality is unknown or it may be
inferior in quality. Kerosene, which is very low in cetane rating,
adversely affects the engine. Diesel fuel differs in grades
depending on the temperature.
Be careful not to let the fuel tank become empty, or air can
enter the fuel system, necessitating bleeding before next
engine start.
C. Air Bleeding The Fuel System
CAUTION
DO NOT BLEED A HOT ENGINE AS THIS COULD CAUSE
FUEL TO SPILL ONTO A HOT EXHAUST MANIFOLD
CREATING A DANGER OF FIRE.
Air bleeding of the fuel system is required if:
---
after the fuel filter and pipes have been detached and
refitted,
---
after the fuel tank has become empty, or
---
before the engine is to be used after a long storage.
[PROCEDURE A] (gravity feed fuel tanks only)
(1.) Fill the fuel tank to the fullest extent. Open the fuel filter lever.
(2.) Loosen air vent plug of the fuel filter a few turns.
(3.) Screw back the plug when bubbles do not come up any
more.
(4.) Open the air vent plug on top of the fuel injection pump.
(5.) Retighten the plug when bubbles do not come up any more.
