------ WARNING! ------

Diesel engine exhaust contains products of combustion which may be harmful to your health

Always start and operate the engine in a well-ventilated area and, if in an enclosed area, vent the exhaust to the outside.


------ WARNING! ------

When it is necessary to work under the machine with the body (bed) raised, attach the body (bed) retaining cables to the rear tow points. Install the rear tow point pins through the ends of the retaining cables.

Failure to properly secure the body (bed) may result in personal injury or death.


For maximum service life of the machine, make a thorough walk-around inspection before you mount the machine.

Look around the machine and under the machine. Inspect the condition of all major components. Look for the following discrepancies:

  • loose bolts

  • trash buildup

  • oil, coolant, or fuel leaks

  • broken parts or worn parts

  • cracks in the frame or crack in the truck body

Note: Rust behind a bolt may indicate that the bolt is loose. Shiny metal areas around a bolt may indicate that the bolt is loose.

Remove any trash and any debris. Report any condition that requires service to the shop. Make sure that any necessary repairs are completed before you operate the machine.

Note: If the machine is equipped with an engine block heater, first connect the one end of the power cable to the engine block heater. Next, connect the other end of the power cable to the power outlet. Before starting the machine or moving the machine, disconnect the end of the power cable from the power outlet. Then, disconnect the other end of the power cable from the engine block heater.

Perform all daily service requirements at the beginning of each shift. Refer to the Operation and Maintenance Manual for the procedures.
