Check The Cooling System - Toro GROUNDSMASTER 580-D 30581 Operator's Manual

Before Operating
1. Dipstick
The engine uses any high-quality detergent oil having the
American Petroleum Institute—API—"service
classification" CD. Oil viscosity recommendations are:
AMBIENT TEMPERATURE
–28.9° to –6.7°C
–6.7° to 40.6°C
40.6° C and up
Note: Do not use multi-viscosity oils.
1. Engine Oil Fill Cap
IMPORTANT: Check oil after every 5 hours operation,
or daily. Change the oil and filter after the first 50
hours, then change both every 100 hours operation
thereafter. Change the oil and filter more often when the
engine is operated in extremely dusty or dirty
conditions.
5. Insert the dipstick into the tube and close and latch
the hood.

CHECK THE COOLING SYSTEM

(DAILY)
The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol anti-freeze. Check the
coolant level at the beginning of each day before starting
the engine. Capacity of the cooling system is 14.7 L.
CAUTION
The best time to check the coolant level is each day
before the engine has been started because the coolant
system has not been pressurized. When the engine is hot
and the radiator cap is removed, pressurized coolant can
escape and cause burns. If engine coolant is hot, slowly
and carefully remove the radiator cap.
1. Unlatch, raise and prop the hood open. Make sure
the hood prop is secured in one of the mounting
brackets on the hood.
2. Remove the radiator cap (Fig. 5). Coolant level
must be above the radiator core and about 25mm
below the bottom of the filler neck.

3. If coolant level is low, add a 50/50 mixture of water
and ethylene glycol anti-freeze. DO NOT USE
ALCOHOL/METHANOL-BASE COOLANTS
OR WATER ONLY. DO NOT OVERFILL.
4. Install the radiator cap, close and latch the hood.
