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.
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.

1. Expansion tank
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.
Adding Fuel
Use only clean, fresh diesel fuel or biodiesel fuels with
low (<500 ppm) or ultra low (<15 ppm) sulfur content.
The minimum cetane rating should be 40. Purchase
fuel in quantities that can be used within 180 days to
ensure fuel freshness.
Fuel tank capacity: 19 US gallons (72 l)
Use summer grade diesel fuel (No. 2-D) at temperatures
above 20° F (-7° C) 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 20° F (-7° C) 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.
WARNING
Fuel is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep fuel away from eyes and skin.
Biodiesel Ready
This machine can also use a biodiesel blended fuel
of up to B20 (20% biodiesel, 80% petrodiesel). The
petrodiesel portion should be low or ultra low sulfur.
Observe the following precautions:
• The biodiesel portion of the fuel must meet
specification ASTM D6751 or EN14214.
• The blended fuel composition should meet ASTM
D975 or EN590.
• Painted surfaces may be damaged by biodiesel
blends.
• Use B5 (biodiesel content of 5%) or lesser blends
in cold weather.
• Monitor seals, hoses, gaskets in contact with fuel as
they may be degraded over time.
• Fuel filter plugging may be expected for a time after
converting to biodiesel blendsd.
• Contact your distributor if you wish for more
information on biodiesel.
