Checking The Cooling System; Servicing The Hydraulic System Fluid - Toro 04383 Operator's Manual

2. Remove the fuel tank cap.
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, sealed, safety-approved
container.
3. Fill the tank until the level is 1/4 to 1/2 in. (6 to
13 mm) below the bottom of the filler neck. Do not
overfill. Install the cap.
4. Wipe up any fuel that may have spilled.

Checking the Cooling System

The capacity of the cooling system is approximately
3.6 qts. (3.4 L).
Clean debris off of the radiator screen and radiator daily
(Fig. 19) or hourly if conditions are extremely dusty and
dirty; refer to Cleaning the Radiator and Screen, page 30.

The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol antifreeze. Check the level
of the coolant at the beginning of each day before starting
the engine.
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. Park the machine on a level surface.
2. Check the coolant level (Fig. 20). It should be between
the lines on the reserve tank when the engine is cold.

3. If the coolant is low, remove the reserve tank cap and
add a 50/50 mixture of water and permanent ethylene
glycol antifreeze. Do not overfill.
4. Install the reserve tank cap.
Servicing the Hydraulic
System Fluid
Recommended Hydraulic Fluid
The hydraulic system is designed to operate on anti-wear
hydraulic fluid. The machine's reservoir is filled at the
factory with approximately 5.5 gallons (20.8 l) of ISO VG
46/48 hydraulic fluid. Check level of hydraulic fluid
before engine is first started and daily thereafter.
Appropriate hydraulic oils are listed below.
Important
Use only types of hydraulic fluids
specified. Other fluids could cause system damage.
