I. Key Points for Startup

• Walk-around inspection: engine oil, hydraulic oil, coolant, tracks, and surrounding environment.

• Get on board, adjust the seat, fasten the seat belt, and confirm the safety lock lever is locked.

• Start without load, idle for warm-up, and observe the instruments.

• Release the safety lock, test all functions at no load first, and begin work only after confirming normal operation.

II. Key Points for Operation

• Stabilize the machine first, keep tracks parallel to the working surface, no overhang or unbalanced load.

• Coordinate the arm and bucket during digging; do not force digging or stall the engine.

• Swing smoothly and evenly; avoid sudden starts, sudden stops, overloading, or violent swinging.

• While traveling, retract the bucket and keep the arm slightly in; stay clear of obstacles and avoid high-speed turns.

• Always observe the surroundings; do not exceed limits or take risks, and maintain a safe distance.

III. Key Points for Shutdown

• Park the excavator on a flat, solid, safe location, not on a slope.

• Lower the bucket flat to the ground, retract the arm and boom, and straighten the upper structure.

• Let the engine idle for cooling before turning off.

• Pull up the safety lock lever, turn off the power, close and lock the door.
