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.
Caution
1. Carefully remove the radiator cap (Fig. 25).

2. Check the coolant level in the radiator. The radiator
should be filled to the middle of the horizontal filler
neck and the surge tank (Fig. 26) should be half way
between Full and Low.

3. If the coolant level is low, replenish the system. Do not
overfill.
4. Install the radiator cap.
Checking the Hydraulic System
Fluid
The machines reservoir is filled at the factory with
approximately 3.3 gallons (12.5 l) of high quality hydraulic
fluid. Check the level of hydraulic fluid before the
engine is first started and daily thereafter. 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
damage caused by improper substitutions, so use only
products from reputable manufacturers who will stand
behind their recommendation.
Multigrade Hydraulic Fluid – ISO VG 46
Normal Climate: 0 (–18C) to 110F (43C)
Mobil DTE 15M
Amoco Rykon Premium ISO 46
Chevron Rykon Premium Oil ISO 46
Conoco Hydroclear AW MV46
Exxon Univis N46
Pennzoil AWX MV46
Shell Tellus T 46
Texaco Rando HDZ 46
Important The ISO VG 46 Multigrade fluid has been
found to offer optimal performance in a wide range of
temperature conditions. For operation in consistently high
ambient temperatures, 65F (18C) to 120F (49C), ISO
VG 68 hydraulic fluid may offer improved performance.
Note: Many hydraulic fluids are almost colorless, making it
difficult to spot leaks. A red dye additive for the hydraulic
system oil is available in 2/3 oz. (20 ml) bottles. One bottle
is sufficient for 4–6 gal (15–22 l) of hydraulic oil. Order
part no. 44–2500 from your authorized Toro distributor.
Not recommended for biodegradable fluid (use food
coloring).
1. Position the machine on a level surface.
