Maintenance

Servicing the Cooling System

Service Interval: Before each use or daily—Clean the
radiator.
Every 100 hours—Check the cooling
system hoses.
Yearly—Change the engine coolant
(Authorized Service Dealer only).
If the engine has been running, the pressurized,
hot coolant can escape and cause severe burns.
• Do not remove the radiator cap when the
engine is hot. Always allow the engine to
cool at least 15 minutes or until the radiator
cap is cool enough to touch without burning
your hand before removing the radiator cap.
• Do not touch radiator and surrounding parts
that are hot.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
Rotating shaft and fan can cause personal
injury.
• Do not operate the machine without the
covers in place.
• Keep fingers, hands and clothing clear of
rotating fan and drive shaft.
• Shut off the engine and remove the ignition
key before performing maintenance.
Swallowing engine coolant can cause poisoning.
• Do not swallow engine coolant.
• Keep out of reach from children and pets.
