Adding Fuel to the Engine
Fuel tank capacity: 182 L (48 US gal)
Fuel type: ultra-low sulfur diesel (ULSD)
Use only diesel fuel for the machine that meets Specification
D975 of the American Society for Testing and Materials
International. See your diesel fuel distributor.
Attachments/Accessories
A selection of Toro approved attachments and accessories is
available for use with the machine to enhance and expand
its capabilities. Contact your Authorized Service Dealer or
Distributor or go to www.Toro.com for a list of all approved
attachments and accessories.
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 only enough
fuel that you expect to use within 30 days to ensure that it
stays fresh.
Use summer-grade diesel fuel (No. 2-D) at temperatures
above 20°F (-7°C) and winter-grade diesel fuel (No. 1-D or
No. 1-D/2-D blend) below 20°F (-7°C). Using winter-grade
22
trailer from a portable container rather than from a fuel
dispenser nozzle.
fuel at lower temperatures provides a lower flash point and
cold flow characteristics, which aid in starting the engine and
help prevent clogging the fuel filter.
• If you must use a fuel dispenser nozzle, keep the nozzle in
contact with the rim of the fuel tank or container opening
at all times until fueling is complete.
Using summer-grade fuel above 20° F (-7°C) contributes
toward a longer fuel pump life and increased power compared
to using winter-grade fuel.
Using Biodiesel Fuel
WARNING
Fuel is harmful or fatal if swallowed. Long-term
exposure to fuel vapors can cause serious injury
and illness.
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:
• Avoid prolonged breathing of vapors.
• The biodiesel portion of the fuel must meet specification
ASTM D6751 or EN14214.
• Keep your face away from the nozzle and the
fuel tank opening.
• The blended fuel composition should meet ASTM D975
or EN590.
• Keep fuel away from your eyes and skin.
• Biodiesel blends may damage painted surfaces.
• Use B5 with a biodiesel content of 5% or less in cold

and highly explosive. A fire or explosion from fuel
can burn you and others and can damage property.
the fuel, as they may degrade over time.
• The fuel filter may become plugged for a time after
converting to a biodiesel fuel blend.
• Fill the fuel tank outdoors in an open area when
the engine is cold. Wipe up any fuel that spills.
• Contact your distributor for more information about
biodiesel fuel.
• Never fill the fuel tank inside an enclosed area.
• Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
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.
• Store fuel in an approved container, and keep
it out of the reach of children. Never buy more
than a 30-day supply of fuel.
• Do not operate the machine without the entire
exhaust system in place and in proper working
condition.
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.
In certain conditions, fueling can release static electricity and
cause a spark, which can ignite the fuel vapors. A fire or
explosion from fuel can burn you and others and can damage
property.
1. Clean around the fuel-tank cap (Figure 19), and remove
the cap from the tank.
• Always place fuel containers on the ground, away from
your vehicle before filling.
• Do not fill fuel containers inside a vehicle or on a truck
or trailer bed, because interior carpets or plastic truck
bed liners may insulate the container and slow the loss
of any static charge.
• When practical, remove the equipment from the truck
or trailer, and refuel the equipment with its wheels on
the ground.
• If refuelling the equipment with its wheels on the ground
is not possible, then refuel such equipment on a truck or

Checking the Engine-Oil Level
Service Interval: Before each use or daily
Note: The engine is shipped with oil in the crankcase;
however, check the oil level before and after you first start
the engine.
Oil specification: API classification of CJ-4 or higher
Use only high-quality SAE 15W-40 heavy-duty engine oil with
an API classification of CJ-4 or higher.
While SAE 15W-40 oil with an API classification of CJ-4 or
higher is recommended for most climates, refer to Figure 22
for oil viscosity recommendations for extreme climates.
Figure 23
1. Dipstick
2. Dipstick tube
Figure 22
Note: Limited use of low-viscosity oils such as SAE 10W-30
with an API classification of CJ-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.
Figure 24
5. Insert the dipstick fully into the dipstick tube, then
remove the dipstick (Figure 23).
Toro Premium Engine Oil is available from an Authorized
Toro Service Dealer in either 15W-40 or 10W-30 viscosity
with API classification CJ-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.
6. Read the oil level on the dipstick (Figure 24).
Note: The oil level on the dipstick should be between
the H (high) mark and L (low) mark.
Important: If the oil level in the crankcase is too low
or too high and you run the engine, you may damage
the engine.
• If the oil level is too low, slowly pour a small
amount of the specified oil into the oil-filler neck
(Figure 65) and wait 3 minutes; refer to step 1 in
Filling the Engine with Oil (page 48).
Note: The best time to check the engine oil is when the
engine is cool before it has been started for the day. If the oil
level is at or below the Add mark on the dipstick, add oil to
the engine to bring the oil level up to the Full mark. Do not
overfill. If the oil level is between the Full and Add marks on
the dipstick, you do not need to add oil.
Important: Do not overfill the engine with oil.
• If the oil level is too high, drain the excess oil until
you obtain the correct oil level on the dipstick;
refer to Draining the Engine Oil (page 47).
1. Ensure that the machine is on a level surface.
7. Repeat steps 4 through 6 until the oil level is correct.
2. Lower all attachments, set the parking brake, stop the
engine, and remove the key.
8. Install the dipstick and oil-fill cap securely.
9. Install the left-side panel; refer to Installing the Side
Panels (page 46).

Note: Do not run the engine at full throttle below the peak
torque rpm (refer to the engine data plate for the peak torque
rpm) for more that 30 seconds.
4. Set the parking-brake button to the On position; refer
to Parking-Brake Switch (page 17).
Note: Do not run the engine at a low idle speed for long
periods of time, because it causes a low operating temperature
that can allow acids and deposits to form in the engine oil.
5. Ensure that all control levers are in the Neutral or
the Stop position; refer to Foot Pedal (page 18),
Utility-Traction Joystick (page 18), and Vibratory-Plow
/ Trencher-Motor Joystick (page 19).
Note: Do not operate the engine at full throttle below the
peak torque rpm (refer to the engine data plate for peak
torque rpm) for more than 30 seconds. Operating the engine

Operating the Machine in
Extreme Conditions
Both hot and cold weather place unusual demands upon
the machine and the attachments. You can minimize
temperature-related problems on the machine by performing
the following steps:
Operating the Machine in Hot Weather
1. Clean all dirt and debris from the radiator, heat
exchanger, hydraulic-fluid cooler, and engine area to
ensure that there is proper air flow to cool the engine.
2. Remove any debris from the air inlets in the nose and
side panels.
3. Use lubricants that have the correct viscosity; refer to
Changing the Engine Oil and Filter (page 47).
4. Operate the machine at an appropriate engine speed
and transmission range for the operating conditions;
do not overload the engine.
5. Use pressure-testing equipment to test the radiator cap
before the hot weather begins; replace the cap if it is
damaged.
6. Maintain the correct coolant level in the reservoir and
in the radiator, and ensure that there is a mixture of
50% ethylene glycol and 50% water in the cooling
system.

Important: If you must temporarily park the
machine on a slope or an incline, position the
machine at a right angle to the slope. Ensure that
the machine is behind an object that will not move.
2. Lower all attachments to the ground.
3. Set the parking brake.
4. Reduce the engine speed to idle and allow it to run for
3 to 5 minutes to adequately cool the engine.
Operating the Machine in Cold Weather
5. Turn the key switch to the Off position.
Operating your machine in cold weather requires special
attention to prevent serious damage to the machine.
Performing the following procedures will extend the service
life of your machine:
1. Clean the battery and ensure that it is fully charged.
Note: If you leave the machine unattended, remove
the key from the key switch.
Breaking in a New or Rebuilt Engine
Note: A fully charged battery at -17ºC (0ºF) has
only 40% of the normal starting power. When the
temperature decreases to -29ºC (-20ºF), the battery has
only 18% of the normal power remaining.
During the first 20 hours of operation of a new or rebuilt
engine, do the following:
• Run the engine at a normal operating temperature.
• Do not run the engine at low idle speeds for long periods
Note: The machine comes with a maintenance-free
battery. If you use a different battery and add water to
it when the temperature is below 0ºC (32ºF), ensure
that you charge the battery or run the engine for about
2 hours to prevent the battery from freezing.
2. Inspect the battery cables and terminals. Clean the
terminals, and apply a coat of grease on each terminal
to prevent corrosion.
3. Ensure that the fuel system is clean and free of water;
refer to Draining Water from the Fuel-Water Separator
(page 24).
