Section i - Introduction Page i-5
• Always use the same fastener part number (or equivalent) when replacing fasteners. Do not use a fastener of
lesser quality if replacements are necessary.
• When necessary, the removal and replacement of any guards covering rotating components, drives, and/or belts
should only be carried out be a trained technician. Before removing any guards the engine must be turned off and
any starting mechanisms must be isolated. All fasteners must be replaced on re-fitting the guards.
• Do not perform any repair when 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 jumper starting or battery charging cables to any ignition or governor control wiring. This can
cause electrical damage to the ignition or governor.
• Always torque fasteners and fuel connections to the required specifications. Overtightening or undertightening can
allow leakage. This is critical to the natural gas and liquefied petroleum gas fuel and air systems.
• Always test for fuel leaks as instructed, as odorant can fade.
• Close the manual fuel valves prior to performing maintenance and repairs, and when storing the vehicle inside.
• Coolant is toxic. If not reused, dispose of in accordance with local environmental regulations.
• The catalyst reagent contains urea. Do not get the substance in your eyes. In case of contact, immediately flood
eyes with large amounts of water for a minimum of 15 minutes. Avoid prolonged contact with skin. In case of
contact, immediately wash skin with soap and water. Do not swallow internally. In the event the catalyst reagent is
ingested, contact a physician immediately.
• The catalyst substrate contains Vanadium Pentoxide. Vanadium Pentoxide has been determined by the State of
California to cause cancer. Always wear protective gloves and eye protection when handling the catalyst assembly.
Do not get the catalyst material in your eyes. In Case of contact, immediately flood eyes with large amounts of
