Checking The Cooling System; Adding Fuel - Toro LT3340 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 debris off of the screen, oil cooler, and front
of the radiator daily and more often if conditions are
extremely dusty and dirty. Refer to
from the Cooling System (page
2. Check the level of the coolant in the expansion tank
(Figure 28).
Note: The coolant level should be between the marks
on the side of the tank.
1. Expansion tank
3. If the coolant level is low, remove the expansion-tank
cap and replenish the system.
Note: Do not overfill.
4. Install the expansion-tank cap.

Adding Fuel

Service Interval: Before each use or daily
Use only clean, fresh diesel fuel with low (<50 ppm) or
ultra-low (<15 ppm) sulfur content. The minimum cetane
rating should be 40. Purchase fuel in quantities that can be
used within 180 days to ensure fuel freshness.
Fuel tank capacity: 45 L (11.9 US 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. 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.
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. 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 fuel 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 180-day supply of fuel.
• Do not operate machine without entire exhaust
system in place and in proper working condition.
