Checking The Cooling System; Checking The Hydraulic-Fluid Level - Toro 04520 Operator's Manual

Checking the Cooling System

The capacity of the cooling system is approximately 4.6 L
(4.9 US qt). Keep the radiator screen clean; refer to
the Radiator Screen (page

Fill the cooling system 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
Note: It should be between the lines on the reserve
tank when the engine is cold.

Checking the Hydraulic-Fluid
Level
The hydraulic-fluid reservoir is filled at the factory with
approximately 20.8 L (5.5 US gallons) of high quality hydraulic
fluid. Before operating the machine each day, check level of
the hydraulic fluid in the white plastic window on the front of
the hydraulic-fluid reservoir (behind the seat on the left side).
The fluid should be between the lines in the window; if not,
add an appropriate fluid as described in the following sections:
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.
