Checking The Engine Oil Level - Toro 25430 Operator's Manual

Using Biodiesel 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.
•
Biodiesel blends may be damage painted surfaces.
•
Use B5 with a biodiesel content of 5% or less in cold
weather.
•
Check seals, hoses, gaskets that come in contact with the
fuel, as they may degrade over time.
•
The fuel filter may become plugged for a time after
converting to a biodiesel fuel blend.
•
Contact your distributor for more information about
biodiesel fuel.
Storing Fuel
If you store fuel in a storage tank, it can accumulate foreign
material or water. Keep the fuel storage tank outside, and
keep the fuel as cool as possible. Remove water from the fuel
in the storage container at regular intervals.
Filling the Fuel Tank
Note: Fill the fuel tank of the machine at the end of each day
to prevent condensation in the fuel tank.
1. Clean around the fuel-tank cap (Figure 19), and remove
the cap from the tank.

1. Fuel cap
Note: Remove the cap slowly to reduce the air
pressure buildup.
2. Filler neck
2. Fill the fuel tank to the bottom of the neck to allow
the fuel room to expand.
Note: The fuel tank capacity is 75.7 L (20 US gal).
3. Install the fuel tank cap and tighten it securely by hand.

Checking the Engine Oil Level

Service Interval: Before each use or daily
The engine is shipped with oil in the crankcase; however,
check the oil level before and after you first start the engine.
Use only high-quality SAE 15W-40 heavy-duty engine oil with
an API classification of CH-4 or higher.
While SAE 15W-40 oil with an API classification of CH-4 or
higher is recommended for most climates, refer to Figure 20
for oil viscosity recommendations for extreme climates.

Note: Limited use of low-viscosity oils such as SAE 10W-30
with an API classification of CH-4 or higher can be used for
easier starting and providing sufficient oil flow at ambient
temperatures below -5°C (23°F). However, continuous use of
low viscosity oil can decrease engine life because of wear.
Toro Premium Engine Oil is available from an Authorized
Toro Service Dealer in either 15W-40 or 10W-30 viscosity
with API classification CH-4 or higher. See the Parts Catalog
for part numbers. Also, refer to the Engine Operator's Manual,
included with the machine, for further recommendations.
Important: If the oil level in the crankcase is too low
or too high and you run the engine, you may damage
the engine.
1. Remove the right-side panel; refer to Removing the
Side Panels (page 36).
2. Remove the dipstick (Figure 21) and wipe it clean with
a clean cloth (Figure 21).
