1. Oil-fill cap
Note: When using different oil, drain all old oil from
the crankcase before adding new oil.
5. Install the oil fill cap and dipstick.
6. Close the hood and secure it with the latches.

Checking the Cooling System

Service Interval: Before each use or daily
Check level of coolant at the beginning of each day. Capacity
of system is 12.3 liters (13 quarts).
1. Carefully remove the radiator cap.
CAUTION
If the engine has been running, the
pressurized, hot coolant can escape and cause
burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
1. Expansion tank
2. Check the coolant level in the radiator. The radiator
should be filled to the top of the filler neck and the
expansion tank filled to the FULL mark (Figure 35).
3. If the coolant is low, add a 50/50 mixture of water and
ethylene glycol anti freeze. Do not use water only or
alcohol/methanol base coolants.
4. Install the radiator cap and expansion tank cap.

Filling the Fuel Tank

Fuel tank capacity: 83 liters (22 gallons).
Use only clean, fresh diesel fuel with ultra low (<15
ppm) sulfur content meeting ASTM D 975 or EN 590
specifications. The minimum cetane rating should be 40.
Purchase fuel in quantities that can be used within 180 days
to ensure fuel freshness.
Important: Use of non-ultra low sulfur fuel will cause
damage to the engine emission system.
Use summer grade diesel fuel (No. 2-D) at temperatures
above -7° C (20° F) and winter grade (No. 1-D or No.
1-D/2-D blend) below that temperature. Use of winter grade
fuel at lower temperatures provides lower flash point and
cold flow characteristics which will ease starting and reduce
fuel filter plugging.
Use of summer grade fuel above -7° C (20° F) will contribute
toward longer fuel pump life and increased power compared
to winter grade fuel.
Important: Do not use kerosene or gasoline instead of
diesel fuel. Failure to observe this caution will damage
the engine.
