Checking, Adding, And Bleeding The Engine Coolant - Toro 22323 Operator's Manual

Checking, Adding, and
Bleeding the Engine Coolant
Service Interval: Before each use or daily
Clean debris off of the screen, oil cooler, and front
of the radiator daily and more often if conditions are
extremely dusty and dirty
The cooling system is filled with a 50/50 solution
of water and permanent ethylene glycol antifreeze.
Check the level of coolant in the expansion tank at the
beginning of each day before starting the engine.
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 egine and remove the ignition
key before performing maintenance.
