and tighten it securely.
Checking the Engine-Oil
Level
Before you start the engine and use the machine,
check the oil level in the engine crankcase; refer to
Checking the Engine-Oil Level (page
Checking the Cooling
Systems
Before you start the engine and use the machine,
check the cooling systems; refer to
Engine-Cooling System (page 81)

Filling the Fuel Tank

Fuel Tank Capacity
132 L (35 US gallons)
Fuel Specification
Important:
Use only ultra-low sulphur diesel
fuel. Fuel with higher rates of sulfur degrades
the diesel oxidation catalyst (DOC), which causes
operational problems and shortens the service life
of engine components.
Failure to observe the following cautions may
damage the engine.
•
Never use kerosene or gasoline instead of diesel
fuel.
•
Never mix kerosene or used engine oil with the
diesel fuel.
•
Never keep fuel in containers with zinc plating on
the inside.
•
Do not use fuel additives.

•
Use only clean, fresh diesel fuel or biodiesel fuels.
•
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
fuel (No. 1-D or No. 1-D/2-D blend) below that
temperature.
Note:
Use of winter-grade fuel at lower temperatures
provides lower flash point and cold flow characteristics
which eases starting and reduces fuel filter plugging.
Using summer-grade fuel above -7°C (20°F)
contributes 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% petroleum diesel).
Sulfur content: Ultra-low sulfur (<15 ppm)
Biodiesel fuel specification: ASTM D6751 or
EN14214
Blended fuel specification: ASTM D975, EN590,
or JIS K2204
Important:
The petroleum diesel portion must
be ultra-low sulfur.
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, 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 if you
wish for more information on biodiesel.
