Checking The Cooling System; Adding Fuel - Toro Groundsmaster 3400 Operator's Manual

Checking the Cooling System

Service Interval: Before each use or daily
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.
The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol antifreeze.
1. Clean any debris off of the screen, oil cooler, and the
front of the radiator daily and more often if conditions
are extremely dusty and dirty. Refer to
Debris from the Cooling System (page
2. Check the level of the coolant in the expansion tank
(Figure 23).
Note: Check and ensure the coolant level is between
the marks on the side of the tank.
1. Expansion tank
3. If the coolant level is low, remove the expansion tank

Figure 23
Use only clean, fresh diesel fuel with low (<501 ppm) or ultra
low (<15 ppm) sulfur content. The minimum cetane rating
is 40. To ensure fuel freshness, purchase fuel in quantities
that is used within 180 days.
Fuel tank capacity: 25 L (10 UK gallons).
Use summer grade diesel fuel (No. 2-D) at temperatures
above -7°C (20°F) and winter grade (No. 1-D or No.
1-D/2-D blend) below that temperature. The use of winter
grade fuel at lower temperatures provides lower flash point
and cold flow characteristics which will ease starting and
reduce fuel filter plugging.
The use of summer grade fuel above -7°C (20°F) will
contribute toward longer fuel pump life and increased power
compared to winter grade fuel.
Important: Do not use kerosene or gasoline instead
of diesel fuel. This product is suitable for use with
Biodiesel of up to B7. Failure to observe this caution will
damage the engine.
WARNING
Fuel is harmful or fatal if swallowed. Long-term
exposure to vapors can cause serious injury and
illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or
conditioner opening.
• Keep fuel away from eyes and skin.

DANGER
In certain conditions, fuel is extremely flammable
and highly explosive. A fire or explosion from fuel
can burn you and others and can damage property.
• Fill the fuel tank outdoors, in an open area, when
the engine is cold. Wipe up any fuel that spills.
• Never fill the fuel tank inside an enclosed trailer.
• 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 an approved container and keep it
out of the reach of children. Never buy more
than a 30-day supply of fuel.
• Do not operate without entire exhaust system in
place and in proper working condition.
