containers on the ground, away from your vehicle
before filling.
•
Remove the equipment from the truck or trailer
and refuel it while it is on the ground. If this is not
possible, then refuel from a portable container
rather than a fuel-dispenser nozzle.
•
Do not operate the machine without the entire
exhaust system in place and in proper working
condition.
•
Keep the fuel-dispenser nozzle in contact with
the rim of the fuel tank or container opening at
all times until fueling is complete. Do not use a
nozzle lock-open device.
•
If you spill fuel on your clothing, change your
clothing immediately. Wipe up any fuel that spills.
•
Never overfill the fuel tank. Replace the fuel cap
and tighten it securely.
•
Store fuel in an approved container and keep it
out of the reach of children. Never buy more than
a 30-day supply of fuel.
•
Do not fill the fuel tank completely full. Add fuel to
the fuel tank until the level is 6 to 13 mm (1/4 to
1/2 inch) below the bottom of the filler neck. This
empty space in the tank allows fuel to expand.
– Avoid prolonged breathing of vapors.
– Keep your face away from the nozzle and fuel
tank opening.
– Avoid contact with skin; wash off spills with
soap and water.

Adding Fuel

Recommended Fuel
The engine runs on clean, fresh diesel fuel with
a minimum cetane rating of 40. Purchase fuel in
quantities that can be used within 30 days to ensure
fuel freshness.
Use summer-grade diesel fuel (No. 2-D) at
temperatures above -7°C (20°F) and winter-grade
diesel fuel (No. 1-D or No. 1-D/2-D blend) below
-7°C (20°F). Use of winter-grade diesel fuel at lower
temperatures provides lower flash point and pour
point characteristics, therefore easing startability and
lessening chances of chemical separation of the fuel
due to lower temperatures (wax appearance, which
may plug filters).
Using summer-grade diesel fuel above -7°C
(20°F) contributes toward longer life of the pump
components.
Important:
Do not use kerosene or gasoline
instead of diesel fuel. Failure to observe this
caution will damage the engine.
Biodiesel Ready
This machine can also use a biodiesel blended fuel
of up to B20 (20% biodiesel, 80% petrodiesel). The
petrodiesel portion should be ultra low sulfur.
Observe the following precautions:
•
The biodiesel portion of the fuel 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 blend
in cold weather.
•
Monitor seals, hoses, gaskets in contact with fuel
as they may degrade over time.
•
Fuel filter plugging may be expected for a time
after converting to biodiesel blends.
•
Contact your distributor for more information on
biodiesel.
Filling the Fuel Tank
1. Park the machine on a level surface.
2. Engage the parking brake.
3. Shut off the engine and remove the key.
4. Clean around the fuel-tank cap.
5. Fill the fuel tank to the bottom of the filler neck
(Figure 7).
Note:
Do not fill the fuel tank completely full.
The empty space in the tank allows the fuel to
expand.
