Petroleum Diesel
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.
Use summer-grade diesel fuel (Number 2-D) at
temperatures above -7°C (20°F) and winter-grade
diesel fuel (Number 1-D or Number 1-D/2-D blend)
below -7°C (20°F). Using winter-grade fuel at lower
temperatures provides a lower flash point and
cold-flow characteristics, which will ease starting and
reduce fuel-filter plugging.
Using summer-grade fuel above -7°C (20°F) will
contribute toward longer fuel-pump life and increased
power compared to winter-grade fuel.
Biodiesel
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:
Biodiesel fuel specification: ASTM D6751 or
EN14214
Blended fuel specification: ASTM D975 or EN590
Observe the following precautions:
•
Biodiesel blends may damage painted surfaces.
•
Use B5 (biodiesel content of 5%) or lesser blends
in cold weather.
•
Monitor seals, hoses, and gaskets in contact with
fuel as they may degrade over time.
•
Your machine might plug fuel-filter for a time after
converting to biodiesel blends.
•
Contact your authorized Toto distributor if you wish
for more information on biodiesel.
Adding Fuel
1. Park the machine on a level surface
2. Remove the cap from the fuel tank
3. Fill the tank until the level is 6 to 13 mm (1/4
to 1/2 inch) below the bottom of the filler neck
(Figure 15).
Note:
Fill the tank to about 6 to 13 mm (1/4 to
1/2 inch) below the top of the tank, not the filler
neck.
4. Install the fuel-tank cap tightly after filling the
tank (Figure 15).
Note:
If possible, fill the fuel tank after each use. This
minimizes possible buildup of condensation inside the
fuel tank.
