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. 25) or hourly if conditions are extremely dusty and
dirty; refer to Cleaning the Radiator and Screen, page 34.

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. 26). 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 machine's reservoir is filled at the factory with
approximately 5.5 gallons (20.8 liters) of high quality
hydraulic fluid. Check the level of hydraulic fluid before
the engine is first started and daily thereafter. The
appropriate hydraulic oils are listed below.
The following list is not assumed to be all-inclusive.
Hydraulic fluids produced by other manufacturers may be
used if they can cross reference to find an equivalent to the
products listed. Toro will not assume responsibility for
