Fuel Specification; Filling The Fuel Tank - Toro Greensmaster 3420 TriFlex Operator's Manual

Fuel Specification

•
Fuel tank capacity: 22.7 L (6 U.S. gallons)
•
Recommended Fuel:
– For best results, 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 (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. Using winter-grade
fuel at lower temperatures provides lower flash
point and cold flow characteristics that will
ease starting and reduce fuel filter plugging.
Note:
Using summer-grade fuel above -7°
C (20° F) will contribute toward longer fuel
pump life and increased power compared to
winter-grade fuel.
– 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 blends.
◊ Contact your authorized Toro distributor for
more information on biodiesel.

Filling the Fuel Tank

1. Clean around the fuel-tank cap and remove it
(Figure 23 or Figure 24).

2. Add the specified fuel to the fuel tank until the
level is 25 mm (1 inch) below the bottom of the
filler neck.
This space in the tank allows the fuel to expand.
Important:
Do not fill the fuel tank
completely full.
3. Install the cap.
Note:
You will hear a click sound when the cap
is secure.
