COOLING SYSTEM
Check the radiator coolant every 100 hours of
operation. Use clean water mixed with a
permanent-type, ethylene glycol antifreeze to a
–34
C (–30
F) rating. The coolant level should
be 25 to 50 mm (1 to 2 in) below the filler opening.
FOR SAFETY: When servicing machine, avoid
contact with hot engine coolant.
ATTENTION! Never pour cold water or cold
antifreeze into the radiator of an overheated
engine. Allow the engine to cool down to
avoid cracking the cylinder head or block.
Keep the engine running while adding water.
Clean the radiator screen every 100 hours of
operation.
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 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.
