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 in. (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
Clean debris off of the radiator and oil cooler daily
(Fig. 13). Clean the radiator hourly if conditions are
extremely dusty and dirty; refer to Cleaning the Engine
Cooling System, page 36.

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 U.S.
quarts (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 (Fig. 14).
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.

Checking the Hydraulic System
The machines reservoir is filled at the factory with
approximately 3.5 U.S. gallons (13.2 l) of high quality
hydraulic fluid. Check the level of the hydraulic fluid
before the engine is first started and daily thereafter.
The recommended replacement fluid is:
Toro Premium All Season Hydraulic Fluid
(Available in 5 gallon pails or 55 gallon drums. See
parts catalog or Toro distributor for part numbers.)
Alternate fluids: If the Toro fluid is not available, other
fluids may be used provided they meet all the following
material properties and industry specifications. We do not
recommend the use of synthetic fluid. Consult with your
lubricant distributor to identify a satisfactory product Note:
Toro will not assume responsibility for damage caused by
improper substitutions, so use only products from reputable
manufacturers who will stand behind their
recommendation.
