COOLING SYSTEM

Check the radiator coolant level daily in the
overflow reservoir. Use clean water mixed with a
permanent-type, ethylene glycol antifreeze to a
--34_ C (--30_ F) rating. Add coolant to the
overflow reservoir.
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.
Check the radiator core exterior and hydraulic
cooler fins for debris daily. Blow or rinse all dust,
which may have collected on the radiator, in
through the radiator fins, and out the grill,
opposite the direction of normal air flow. 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.
Flush the radiator and the cooling system every
1600 hours of operation, using a dependable
cleaning compound.
