Machine Walkaround
What is the first step in a walkaround inspection for an excavator?
Check for visible damage or leaks.
What fluid levels must be checked during an excavator walkaround?
Engine oil, hydraulic fluid, coolant, and fuel.
What does “raking the green” refer to when using an excavator?
Leveling or smoothing the surface of a work area.
What does the term “over the moon” refer to in excavator operation?
Lifting materials over a high point or obstacle.
What is the primary purpose of trenching with an excavator?
To create narrow and deep channels for utilities or drainage.
Why is it important to inspect the undercarriage during a walkaround?
To check for excessive wear or damage that could affect stability.
Why should you inspect the boom and arm for cracks or wear?
To ensure structural integrity and safe operation.
Why is precision important when raking a green surface?
To create a level and consistent base for construction or landscaping.
What safety concern should you consider when lifting loads “over the moon”?
Ensuring the load does not exceed the machine’s capacity.
What should you check for in the work area before starting a trenching operation?
Underground utilities, stability of the ground, and clearance around the machine.
What should you do if you find hydraulic fluid leaking during a walkaround?
Report the issue and do not operate the machine until it is repaired.
What is the purpose of inspecting the cab interior during a walkaround?
To ensure all controls, gauges, and safety devices are functioning properly.
What part of the excavator is most often used for raking the green?
The bucket or blade.
What tool can be used to check the weight of a load before lifting?
A load scale or a load chart.
Why is it important to maintain a consistent trench depth?
To meet project specifications and ensure proper functionality of the utility being installed.
Name one safety feature you should confirm is operational during a walkaround.
Fire extinguisher, seatbelt, or safety alarms.
What should you do if the air filters appear clogged during your inspection?
Clean or replace them according to the manufacturer's recommendations.
Name one factor that can make raking the green more challenging.
Uneven terrain, poor visibility, or operator inexperience.
Why is it important to position the excavator properly before lifting a load?
To maintain stability and avoid tipping.
What tool can help operators ensure they are trenching at the correct depth?
A grade laser or depth gauge.
Where would you check for debris buildup during an excavator walkaround?
In the track rollers, engine compartment, and around pivot points.
What tool is typically used to measure track tension during a walkaround?
A track tension gauge.
What should you check before raking to ensure effective operation?
The bucket teeth and edges for wear or damage.
What is one way to prevent a load from swinging excessively during an “over the moon” operation?
Use smooth and controlled movements.
How can improper trenching impact the safety of the job site?
It can cause cave-ins, damage utilities, or destabilize nearby structures.
