Checking The Cooling System - Toro 30809 Operator's Manual

DANGER
In certain conditions during fueling, static
electricity can be released causing a spark
which can ignite the gasoline vapors. A fire
or explosion from gasoline can burn you and
others and can damage property.
• Always place gasoline containers on the
ground away from your vehicle before
filling.
• Do not fill gasoline containers inside a
vehicle or on a truck or trailer bed because
interior carpets or plastic truck bed liners
may insulate the container and slow the
loss of any static charge.
• When practical, remove gas-powered
equipment from the truck or trailer and
refuel the equipment with its wheels on
the ground.
• If this is not possible, then refuel such
equipment on a truck or trailer from a
portable container, rather than from a
gasoline dispenser nozzle.
• If a gasoline dispenser nozzle must be
used, keep the nozzle in contact with the
rim of the fuel tank or container opening at
all times until fueling is complete.

Checking the Cooling System

Service Interval: Before each use or daily
The capacity of the cooling system is approximately 5.7 liters.
(6 quarts).
Clean debris off of the radiator/oil cooler daily (Figure 28).
Clean the radiator/oil hourly if conditions are extremely dusty
and dirty; refer to Cleaning the Engine Cooling System.
1. Radiator/Oil cooler
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.
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. Check the coolant level in the expansion tank (Figure
29). With a cold engine, the coolant level should be
approximately midway between the marks on the side
of the tank.
2. If the coolant level is low, remove the expansion tank
cap and replenish the system. Do not overfill.
3. Install the expansion tank cap.
