Study Notes
Operation Basics
- Move the transmission controller/gear selector to Neutral before starting the engine or dismounting the machine.
- Maintain Good ground contact between the nozzle and filler neck while fueling to prevent spills.
Console and Controls
- Directional indicator, high beam, horn button, fuel gauge, articulation indicator, and monitor panel are located on the Front console.
- The radiator filler cap should not be removed unless the engine is cool.
Engine Operation
- During cold weather warm-up, run the engine at 1000 rpms for 5 minutes.
- The engine oil pressure gauge should rest in the Green zone when at full operating temperature.
Machine Controls
- Clutch, brake, accelerator, and deceleration pedals are crucial for control.
- The Front wheel lean lever helps reduce the grader's turning circle, and articulation can further assist.
Traction and Safety

- The moldboard is commonly referred to as the Blade when completely assembled.
Moldboard Mechanics
- The leading end of the moldboard at an angle is known as the Toe, while the trailing end is known as the Heel.
- When spreading or compacting material, the moldboard should be tilted forward.
Grading Techniques
- Side thrust is controlled by leaning the front wheels in the direction of material moving across the moldboard.
- The ripper should be lowered into the ground while moving for effective cutting.
Grading Procedure
- The first pass when cutting a vee ditch is known as the Marking pass.
- Finish grading a slope by starting at the Top and stopping at the Bottom.
Tire and Operator Safety
- Check tires for cuts, uneven or excessive tread wear in addition to abrasions.
- Always operate the machine while directly seated; avoid operating across Slope.
Electrical and Temperature Monitoring
- Disable the entire electrical system via the Battery disconnect switch.
- The gauge needle indicates excessive coolant temperature when positioned in the Red zone.
Operating Alerts
- Category 2 warning requires a change in machine operation; stop the machine immediately upon engine oil or hydraulic pressure indicator alert.
Controls and Indicators
- The left brake pedal is responsible for down-shifting the transmission.
- To determine transmission speed, rotate the switch on the direction selector lever.
Lift Control Mechanics
- Lift control is in Float when at the forward detent position.
- Release the toggle switch when audible clicks are heard while opening or closing the hood.
Safety and Transport
- Prior to transportation, lifting, or servicing, always secure the machine in the Lock position with the steering frame lock.
- Descend an incline with a loaded bucket in Reverse to prevent material spillage.
Operating Techniques
- When loading, ensure to remove overhang and watch for sliding material.
- When carrying a loaded bucket low, this enhances visibility for the operator and stability for the load.
Engine Oil Maintenance
- Maintain engine oil on the dipstick within the Safe starting range.
Excavator Operations
- The excavator's ADR mission supports civil engineering.
- Start machine readiness with a walk around inspection and only mount from designated Steps/Handholds.
Starting and Traveling
- Limit cranking the engine to no more than 30 seconds when starting.
- Check seat belts in addition to mounting hardware before operation.
Travel Mechanisms
- Travel in the excavator is accomplished through either travel pedals or travel levers.
- To move forward, press the front part of both pedals; for reverse, push the rear parts.
Turning and Hydraulic Systems
- Pushing down on specific pedals allows for Turning: left or right.
- Spot turning occurs when a pedal's front is pushed down with the rear of another.
Control Mechanism
- Hydraulic activation control is essential for excavator operations.
- Release of a control lever will result in a Return to hold position.
Maneuvering and Safety
- Reduce engine speed during tight maneuvering or on inclines.
- Avoid using swing force on operations like groundbreaking and demolition.
Lifting Protocol
- Fasten cables or chains to a Lifting bar when lifting loads.
- To dump a load, ensure the stick is outward and the bucket is positioned smoothly.
