COOLING SYSTEM
Check the radiator core exterior for debris every
100 hours of operation. Blow or rinse all dust,
which may have collected on the radiator, in
through the grille and radiator fins, opposite the
direction of normal air flow. The grille and
hydraulic cooler open for easier cleaning. Be
careful not to bend the cooling fins when cleaning.
Clean thoroughly to prevent the fins becoming
encrusted with dust. Clean the radiator and cooler
only after the radiator has cooled to avoid
cracking.
FOR SAFETY: When Servicing Machine,
Wear Eye And Ear Protection When
Using Pressurized Air Or Water.
Check the radiator coolant level every 100 hours
of operation. Use clean water mixed with a
permanent-type, ethylene glycol antifreeze to a
–34
C rating.
FOR SAFETY: When Servicing Machine,
Avoid Contact With Hot Engine Coolant.
Check the radiator hoses and clamps every
200 hours of operation. Tighten the clamps if they
are loose. Replace the hoses and clamps if the
hoses are cracked, harden, or swollen.
Flush the radiator and the cooling system every
800 hours of operation, using a dependable
cleaning compound.
