Cooling System Safety

•
Swallowing engine coolant can cause poisoning;
keep out of reach from children and pets.
•
Discharge of hot, pressurized coolant or touching
a hot radiator and surrounding parts can cause
severe burns.
– Always allow the engine to cool at least 15
minutes before removing the radiator cap.
– Use a rag when opening the radiator cap, and
open the cap slowly to allow steam to escape.
Checking the Cooling
System
Service Interval: Before each use or daily
Clean debris off the radiator daily
the radiator hourly if conditions are extremely dusty
and dirty; refer to Cleaning the Engine Cooling System
(page 48).

1. Radiator
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol antifreeze.
Check the coolant level at the beginning of each day
before starting the engine.
The capacity of the cooling system is approximately
5.7 L (6 US qt).

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. Park the machine on a level surface, lower the
cutting units, engage the parking brake, shut off
the engine, and remove the key.
2. Check the coolant level in the expansion tank
(Figure 60). With a cold engine, the coolant
level should be approximately midway between
the marks on the side of the tank.
3. If the coolant level is low, remove the
expansion-tank cap and replenish the system.
Do not overfill the tank.
4. Install the expansion-tank cap.
