ENGINE MAINTENANCE:
Refer to the engine manual for engine maintenance.
AIR CLEANER SERVICE:
LP Engine:
Clean out the dust cup every 50 hours. Loosen the clamps around the cup and housing and
remove the cup. Dump dust out of cup. Clean gasket and sealing surfaces with a damp cloth.
Replace cup gasket if it shows signs of damage. Replace cup with arrows pointing up and
tighten clamp.
Clean the intake cap screen every 50 hours, and perform a thorough inspection of the air intake
pipes and joints.
Clean the filter element every 250 hours or every 3 months, whichever comes sooner and re-
place the element every 500 hours or 6 months. Remove and clean the dust cup and gasket,
and the intake cap. Remove the wing nut on the element and gently remove the element.
Bumping the element during removal may cause dirt to fall into the clean air tube. Clean the
inside of the housing carefully with a damp cloth. To clean the element, use a compressed air
blower nozzle with less than 100 PSI and blow air from the inside of the element. Shake dust
off of the outside of the element. Make sure the gaskets and element fit properly and reassem-
ble, being careful not to allow any dust into the intake pipe.
Do not remove an element just for inspection. This may do more harm than good. You cannot
judge the element condition by its appearance. If you think the filter may need service, remove
it and replace or clean it before reassembling air cleaner.
Conditions where more dirt than usual is in the air, especially soot, will make more frequent ser-
vice necessary. If there is a significant amount of dust in the dust cup when it is cleaned every
50 hours, clean the element every 100 hours and replace it every 200 hours--or more frequently
in extremely dusty conditions. Excessive exhaust smoke or loss of power may indicate a
plugged filter.
Diesel Engine:
Check the air filter restriction indicator daily with the engine running. If the indicator is in the
“Replace” zone, replace the primary and secondary filter. If the filter has not been changed for
over 1000 hours, replace the filter regardless of the restriction indicator reading.
COOLING SYSTEM:
Check the level of coolant in the radiator overflow tank daily. Add a mixture of antifreeze and
distilled water to the overflow tank as required to maintain the coolant level. Check the radiator
fins for dirt or debris daily and wash the fins with a pressure or steam cleaner every 50 hours or
as required. Check the antifreeze protection level every 500 hours. Every two years, flush the
cooling system and replace the thermostat and coolant. Pressure test the system as specified
by the engine manufacturer.
SPARE PARTS LIST:
A spare parts list (including oil filter, fuel filter, etc.) may be found in the Parts Manual, under
Engine Installation.
MAJOR ENGINE SERVICING OR OVERHAUL:
Major servicing or overhaul is beyond the scope of this manual. Consult authorized engine ser-
vice manual or rely on an authorized engine service center.
