DRY TYPE AIR CLEANER. Under no engine operating condition should the intake restriction exceed 25 inches
of water for non-turbocharged engines and 20 inches of water for turbocharged engines. A clogged air cleaner
element will cause excessive intake restriction and a reduced air supply to the engine.
Inspect and service the air cleaner element every 20,000 miles, or more often if the engine is operated under
severe dust conditions. Check the gaskets for deterioration and replace, if necessary. If the dry type air cleaner is
equipped with an aspirator, check for aspirator damage or clogging. Clean and repair as necessary.
6.
OIL BATH TYPE AIR CLEANER. Clean and refill the air cleaner oil cup every 4,000 to 6,000 miles. Remove and
steam clean the air cleaner element and baffles annually. Operation under dusty conditions will require more
frequent service.
7.
ENGINE LUBRICATING OIL. Change the initial lubricating oil at approximately 3,000 miles, and at 4,000 6,000
mile intervals thereafter. Drain intervals may be established on the recommendation of an independent oil analysis
laboratory or the oil supplier (based upon the oil sample analysis) until the most practical oil change period has
been determined. Check all lubricating oil lines and connections for wear or chafing.
8.
ENGINE LUBRICATING OIL FILTER. Change the lubricating oil filters when the engine oil is changed.
9.
COOLANT. Check the coolant level daily before starting the engine. Make sure coolant covers the radiator tubes.
Add coolant as necessary. DO NOT OVERFILL. Check all cooling system lines and hoses for damage, leaks or
loose connections. Tighten or replace as necessary.
10.
TURBOCHARGER. Inspect mountings, intake and exhaust ducting, and connections for leaks daily. Check oil
inlet and outlet lines for tight connections, damaged lines or fittings.
