Checking The Cooling System - Toro 30849 Operator's Manual

• 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 distributor if you wish for more
information on biodiesel
1. Clean the area around the fuel tank cap (Figure 21).
2. Remove the fuel tank cap.
3. Fill the tank to the bottom of the filler neck. Do
not overfill. Install the cap.
4. To prevent a fire hazard, wipe up any fuel that may
have spilled.

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.

Checking the Cooling System

Service Interval: Before each use or daily
Clean debris off of the radiator and oil cooler daily
(Figure 22). Clean the radiator hourly if conditions are
extremely dusty and dirty; refer to Cleaning the Engine
Cooling System.
1. Access panel
2. Radiator
The cooling system is filled with a 50/50 solution of
water and permanent ethylene glycol anti-freeze. Check
the coolant level at the beginning of each day before
starting the engine.
The capacity of the cooling system is approximately
6 qt (5.7 l).
CAUTION
If the engine has been running, the pressurized,
hot coolant can escape and cause burns.
• Do not open the radiator cap when the engine
is running.
• Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
1. Check the coolant level in the expansion tank
(Figure 23). With a cold engine, the coolant level
should be approximately midway between the marks
on the side of the tank.
2. If the coolant level is low, remove the expansion
tank cap and replenish the system. Do not overfill.
3. Install the expansion tank cap.
