The course will provide the participant a comprehensive overview of the M, M2, and M3 Series of Motor Graders. Individual Machine Systems including Cab, Engine, Powertrain, Working Hydraulics, Steering, andBrake/Fan Circuit will all be identified and reviewed.

Students must bring their own safety glasses, steel toed boots, gloves, hard hat and coveralls with hi-visibility markings.

Please note, this course does NOT cover the 24M Series of Motor Grader - there is a separate course for that machine.

After completion of the course, the participant will be able to:

• Compare and state differences between the M, M2, and M3 series respectively.
• Compare and state differences across the 120M to 18M3 model range of machines.
• Locate and identify the key components for all Machine systems.
• Locate and identify all service points on the Machines.
• Discuss major service/maintenance procedures.
• State all the engine models used for each machine series/model.
• Overview the respective engine emission controls for Tier 4 Interim/Final equipped machines.
• State the function of the components in the Powertrain System.
• Trace the flow of energy throughout the Powertrain System.
• Pressure test the Transmission for proper clutch operation / Perform clutch calibrations.
• Identify and define the separate functions of the Primary - and Secondary Steering Systems.
• Identify and discuss function of the components in the Pilot and Implement Hydraulic Systems.
• Trace the flow of oil through the Pilot and Implement Hydraulic Systems.
• Pressure test and adjust the PPPC Hydraulic System to optimize machine functionality.
• Identify and describe all components of the Brake/Fan Circuit.
• Identify and describe all components of the optional AWD (All Wheel Drive) System.

Successful completion of a written examination with a passing grade of 80%.
