Operation; Checking The Engine Oil Level; Filling The Fuel Tank - Toro 03170 Operator's Manual

Operation

Note: Determine the left and right sides of the
machine from the normal operating position.

Checking the Engine Oil Level

Service Interval: Before each use or daily
The engine is shipped with oil in the crankcase;
however, the oil level must be checked before and after
the engine is first started.
Crankcase capacity is approximately 4 qt. (2.8 l) with
the filter.
Use high-quality engine oil that meets the following
specifications:
• API Classification Level Required: CH-4, CI-4 or
higher.
• Preferred oil: SAE 15W-40 (above 0ºF (-17ºC))
• Alternate oil: SAE 10W-30 or 5W-30 (all
temperatures)
Note: Toro Premium Engine oil is available from a
distributor in either 15W-40 or 10W-30 viscosity. See
the parts catalog for part numbers.
Note: The best time to check the engine oil is when
the engine is cool before it has been started for the
day. If it has already been run, allow the oil to drain
back down to the sump for at least 10 minutes before
checking. If the oil level is at or below the "add" mark
on the dipstick, add oil to bring the oil level to the "full"
mark. Do not overfill. If the oil level is between the
"full" and "add" marks, you do not need to add oil.
1. Position the machine on a level surface.
2. Remove the dipstick (Figure 35) and wipe it with
a clean rag.

3. Push the dipstick down into the dipstick tube and
ensure that it is seated fully, then pull the dipstick
out and check the oil level.
4. If the oil level is low, remove the oil fill cap
(Figure 36) and gradually add small quantities of oil,
checking the level frequently, until the level reaches
the Full mark on the dipstick.

5. Install the oil fill cap and close the hood.
Important: Be sure to keep the engine oil level
between the upper and lower limits on the oil
gauge. Engine failure may occur as a result of
over filling or under filling the engine oil.

Filling the Fuel Tank

DANGER
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others and
can cause property damage.
• Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
• Do not fill the fuel tank completely full. Add
fuel to the fuel tank until the level is 1/4 to 1/2
inch (6 to 13 mm) below the bottom of the filler
neck. This empty space in the tank allows the
fuel to expand.
• Never smoke when handling fuel, and stay
away from an open flame or where fuel fumes
may be ignited by a spark.
• Store fuel in a clean, safety-approved container
and keep the cap in place.
Use only clean, fresh diesel fuel or biodiesel fuels with
low (<500 ppm) or ultra low (<15 ppm) sulfur content.
