ENGINE OPERATION - Safety - Introduction When working on the vehicle, be alert for hot parts on systems that have just been turned off, exhaust gas flow, and hot fluids in lines, tubes, and compartments. Contact with any hot surface may cause burns. Always use tools that are in good condition. Make sure you have the proper understanding of how to use the tools before performing any service work. Use only genuine replacement parts from PACCAR. Always use the same fastener part number (or equivalent) when replacing items. DO NOT use a fastener of lesser quality if replacements are necessary.
(e.g., Do not replace a 10.9 grade with 8.8 grade fastener.) Always torque fasteners and fuel connections to the required specifications. Overtightening or under-tightening can allow leakage. Close the manual fuel valves prior to performing maintenance and repairs, and when storing the vehicle inside. DO NOT perform any repair when impaired, tired, fatigued or after consuming alcohol or drugs that can impair your functioning. Some state and federal agencies in the United States of America have determined that used engine oil can be carcinogenic and can cause reproductive toxicity. Avoid inhalation of vapors, ingestion, and prolonged contact with used engine oil.
DO NOT connect the jump starting or battery charging cables to any ignition or governor control wiring. This can cause electrical damage to the ignition or governor. Coolant is toxic. If not reused, dispose of coolant in accordance with local environmental regulations. California Proposition 65 Warning 1 Diesel engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. The catalyst substrate located in the Diesel Particulate Filter (DPF) contains vanadium pentoxide, which has been determined by the State of California to cause cancer.
Always wear protective clothing and eye protection when handling the catalyst assembly. Dispose of the catalyst in accordance with local regulations. If catalyst material gets into the eyes, immediately flood eyes with water for a minimum of 15 minutes. Avoid prolonged contact with skin. In case of contact, immediately wash skin with soap and water. In case of harmful contact, immediately contact a physician. Other chemicals in this vehicle are also known to the State of California to cause cancer, birth defects or other reproductive harm. Battery posts, terminals, and related accessories contain lead CAUTION Corrosive chemicals can damage the engine.
DO NOT use corrosive chemi- cals on the engine. Failure to comply may result in equipment, or property damage. Y53-1166-1G1 (08/2018) 9
