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

2. Remove the fuel tank cap.
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). Refer to Cleaning the Radiator and Screen.
Figure 31
1. Radiator screen
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 (Figure 32). It should be
between the lines on the reserve tank when the engine
is cold.

1. Reserve tank
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.
Checking the Hydraulic Fluid
Level
Recommended Hydraulic Fluid
The machines reservoir is filled at the factory with
approximately 5.5 gallons (20.8 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 as follows:
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.
