DIESEL MODELS: CHECK THE
COOLING SYSTEM
Clean debris off the radiator screen, radiator and oil
cooler daily (Fig. 5), or hourly if conditions are extreme-
ly dusty and dirt.
The cooling system is filled with a 50/50 solution of
water and permanent ethylene glycol anti-freeze. Check
the level of coolant at the beginning of each day before
you start the engine. Capacity of the cooling system is
5.0 liters.
1. Carefully remove the cap from the radiator.
2. Check the level of coolant in the radiator. The radi-
ator should be filled to the top of the filler neck.
3. If the coolant level is low, replenish the system.
DO NOT OVERFILL. If coolant is added, bleed-
ing the system may be required; refer to Bleeding
The Cooling System.
4. Install the radiator cap.
CHECK THE HYDRAULIC
SYSTEM FLUID
The hydraulic system is designed to operate with Mobil
DTE26 or equivalent anti-wear hydraulic fluid. The
machine’s system is filled at the factory with approxi-
mately 12.5 liters (3.3 gallons) of fluid. However, check
the level of hydraulic fluid before you first start the
engine and daily thereafter.
Hydraulic Oil (recommended brands): (ISO 68)
Mobil DTE26
Shell Tellus 68
Amoco Rykon Oil #68
Conoco Super Hydraulic Oil 68
Exxon Nuto 68
Kendall Kenoil R&O AW 68
Pennzoil Penreco 68
Phillips Magnus A 68
Standard Energol HLP 68
Sun Sunvis 831 WR
Union Unaz AW 68

Note: All are interchangeable.
IMPORTANT Use only the hydraulic oils speci-
fied. Other fluids could cause system damage.
Note: A red dye additive for the hydraulic system oil is
available in 20 ml. (2/3 oz) bottles. One bottle is suffi-
cient for 15–23 liters (4–6 gal.) of hydraulic oil. Order
Part No. 44-2500 from your authorized Toro distributor.
1. Position the machine on a level surface.

removed and cause burns.
