AIR CLEANER SERVICE:
Clean out the dust cup every 50 hours. Loosen the clamps around the cup & 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 replace the element every 500 hours or 6 months. Remove and clean the dust cup &
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 (7 bar) 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 reassemble, 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 frequent
service more 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.
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 2 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. Replace engine parts only with genuine OEM parts, as
required by EPA regulations.
MAJOR ENGINE SERVICING OR OVERHAUL:
Major servicing or overhaul is beyond the scope of this manual. Consult authorized
engine service manual or rely on an authorized engine service center.
