Cooling System
Maintenance
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.
• Do not operate the machine without the covers
in place.
• Keep your ngers, hands, and clothing clear of the
rotating fan and drive belt.

Checking the Cooling
System and Coolant Level
Service Interval : Before each use or daily
W ARNING
If the engine has been running, the radiator
will be pressurized and the coolant inside will
be hot. If you remove the cap, coolant may
spray out, causing severe burns.
• Do not remove the recovery-tank cap to
check coolant levels. Instead, look at the
level from the side of the tank.
• Do not remove the recovery-tank cap
when the engine is hot. Allow the engine
to cool for at least 15 minutes or until
the radiator cap is cool enough to touch
without burning your hand.
1. Check the level of the coolant in the expansion
tank ( Figure 7 ).
2. If the coolant is low , remove the expansion-tank
cap and add the recommended replacement
coolant as required.
Do not use water only or alcohol-based
coolants. Do not overll .
3. Install the expansion-tank cap.
