  1. When inspecting the undercarriage of a mini excavator, which component should be checked for proper tension?

    Answer: Track chain/belt

    Track tension must be checked regularly because improper tension causes accelerated wear, derailment, or drivetrain damage.

  2. A mechanic notices the swing bearing on a mini excavator has excessive play. What is the safest immediate action?

    Answer: Tag the machine out of service and notify a supervisor

    Excessive swing bearing play is a structural safety hazard that requires the machine to be taken out of service until repaired.

  3. Which fluid level should be checked BEFORE starting a mini excavator each day?

    Answer: Engine oil, hydraulic fluid, and coolant

    Pre-shift inspections require checking engine oil, hydraulic fluid, and coolant to prevent equipment damage during operation.

  4. What does a milky or foamy appearance in the hydraulic reservoir indicate?

    Answer: Water contamination in the hydraulic fluid

    A milky or foamy appearance indicates water has entered the hydraulic system, which degrades performance and causes corrosion.

  5. How often should the engine air filter on a mini excavator typically be inspected in dusty conditions?

    Answer: Daily or as indicated by the restriction indicator

    In dusty environments, air filters can clog rapidly and should be checked daily or whenever the restriction indicator signals a clogged filter.

  6. Which of the following is a sign that a mini excavator's cooling system needs immediate attention?

    Answer: Steam or coolant leaking from the engine compartment

    Steam or visible coolant leaks indicate an active cooling system failure that can cause engine overheating and severe damage if not stopped immediately.

  7. When greasing a mini excavator's bucket pins and bushings, what indicates the grease point has received enough lubrication?

    Answer: Fresh grease purges out around the joint

    Fresh grease purging out around the joint indicates that old contaminated grease has been displaced and the fitting is fully lubricated.
