Cooling System
Maintenance
Servicing the Cooling
System
Service Interval: Before each use or daily—Clean the screen,
oil cooler, and front of the radiator (more
often in dirty or dusty conditions).
Before each use or daily—Check the coolant level in
the expansion tank.
Every 100 hours—Check the cooling system hoses.
Yearly—Change the engine coolant (Authorized
Service Dealer only).
DANGER
If the engine is 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 the 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.
DANGER
The rotating shaft and fan can cause personal
injury.
• Do not operate the machine without the covers
in place.
• Keep your fingers, hands, and clothing clear of
the rotating fan and drive shaft.
• Park the machine on a level surface, lower the
loader arms, engage the parking brake, shut off
the engine, and remove the key from the key
switch before performing maintenance.
CAUTION
Swallowing engine coolant can cause poisoning.
• Do not swallow engine coolant.
• Keep out of reach from children and pets.
Cleaning the Radiator Screen
Before each use, check and clean the radiator screen, located
in front of the operator platform. Remove any buildup of
grass, dirt or other debris from the radiator screen with
compressed air.
Checking the Engine-Coolant
Level
The cooling system is filled with a 50/50 solution of water
and permanent ethylene-glycol antifreeze.
1. Park the machine on a level surface, lower the loader
arms, engage the parking brake, and shut off the engine.
2. Remove the key from the key switch and allow the
engine to cool.
3. Check the coolant level in the expansion tank ( Figure
63 ).
The coolant level should be at or above the mark on
the side of the tank.
