Your vehicle may be equipped with Optima brand Absorbed Glass Mat (AGM) batteries located in the cab under the passenger’s seat. The glass mat in AGM batteries is designed to absorb the battery acid inside the battery that can leak or spill out in conventional batteries. This design feature allows Optima batteries to be positioned in any orientation without risk of leaking.

Engine heat, vibration, and age combine to loosen air intake connections and cause cracks in the tubing and elbows. Leaks in the intake system allow abrasive dust to enter the engine and quickly cause expensive damage.

Check all tubing, elbows, clamps supports and fasteners for condition and tightness.

Check the Charge-Air-Cooler for air leaks annually.

The air leaks can be caused by cracked tubes or header. For service see your authorized Kenworth Dealer.

CAUTION: Do not use air intake pipes and connections as a step or to pull yourself up. This could loosen the connections and open the system to unfiltered air which could damage the engine.

WARNING!: Do not use brake linings with a thickness below the specified minimum. Such linings will have lining rivets exposed that can damage the brake drum and reduce brake efficiency, which could cause an accident or system failure. Failure to comply may result in death, personal injury, equipment or property damage.

Brake linings inspected by a qualified mechanic at an authorized Kenworth Dealer for wear

See Table 9, Maintenance Schedule on page 5-18. In severe service applications inspect the linings more frequently.
