Checking The Cooling System; Checking The Hydraulic System Fluid; Filling The Fuel Tank - Toro 30581 Groundsmaster 580-D Operator's Manual

Important
Check oil after every 5 hours operation or
daily. Change oil and filter after the first 50 hours, then
change both every 100 hours operation thereafter. Change
oil and filter more frequently when engine is operated in
extremely dusty or dirty conditions.
4. Insert dipstick into tube and close and latch hood.

Checking the Cooling System

The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol anti-freeze. Check coolant
level at beginning of each day before starting the engine.
Capacity of cooling system is approximately 3.9 gal.
(14.7 l).
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. Unlatch, raise and prop hood open. Make sure hood
prop is secured in one of the mounting brackets on
hood.
2. Remove radiator cap (Fig. 5). Level of coolant must be
above the radiator core and about 1 in. (25 mm) below
bottom of 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 radiator cap, close and latch the hood.
Checking the Hydraulic System
Fluid
1. Fluid level should be checked daily through sight glass
1. Hydraulic oil level sight
2. If oil level is low, add hydraulic oil to the reservoir

Filling the Fuel Tank

The engine runs on ASTM No. 2-D diesel fuel.

at rear of hydraulic reservoir (Fig. 6). When oil is cold,
level will be slightly below center, but should be in the
middle of the sight glass when the oil is warm.

Danger
Under certain conditions, diesel fuel and fuel
vapors are highly flammable and explosive. A fire
or explosion from fuel can burn you and others
and can cause property damage.
Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is off and is cold.
Wipe up any fuel that spills.
Do not fill the fuel tank completely full. Add fuel
to the fuel tank until the level is 1 in. (25 mm)
below the bottom of the filler neck. This empty
space in the tank allows the fuel to expand.
Never smoke when handling fuel, and stay away
from an open flame or where fuel fumes may be
ignited by a spark.
Store fuel in a clean, safety-approved container
and keep the cap in place.
