Pre-Operation Inspection
Perform a comprehensive pre-start inspection of the Caterpillar excavator before commencing work to ensure stable mechanical performance and operational safety:

1. Power & Liquid Inspection: Check engine oil, coolant and diesel levels to ensure they are within the standard range; inspect oil pipelines and hydraulic pipelines for leakage, aging and blockage.
2. Chassis & Track Inspection: Check rubber track tension and wear status; inspect chassis rollers, idlers and driving wheels for jamming and abnormal wear; clean track sundries.
3. Working Device Inspection: Check boom, stick and bucket for deformation and crack; confirm bucket teeth and connecting pins are firm; test the flexible operation of each hydraulic action.
4. Safety & Electrical Inspection: Test emergency stop function, working lights and instrument display; check bulldozer blade telescopic and lifting functions for normal operation.

Standard Starting & Warm-Up Operation

1. Park the excavator on flat and solid ground, lower the bucket and bulldozer blade to touch the ground, and release the operating lever to the neutral position before starting.
2. Start the engine and keep idle warm-up for 3–5 minutes in low temperature environment; observe the instrument data to ensure no fault alarm and stable engine operation.
3. Test single actions such as boom lifting, stick expansion and contraction, bucket rotation and body rotation after warm-up to confirm smooth hydraulic operation without abnormal noise.

Construction Operation Specifications

1. Excavation Operation: Keep the vehicle body stable, use the bulldozer blade to assist in fixing the body during slope and deep excavation; adopt layered excavation to avoid overloading the bucket and violent digging, preventing arm body deformation and hydraulic system damage.
2. Narrow Space Operation: Make full use of zero-tail swing performance, control rotation speed slowly, avoid collision with surrounding buildings and obstacles; adjust track width according to site space to ensure flexible passing.
3. Leveling & Backfilling: Cooperate with the bulldozer blade and bucket for fine leveling and trench backfilling, maintain uniform operation speed to ensure flat construction effect.
4. Multi-Attachment Operation: Replace breakers, grabbers and other accessories strictly in accordance with specifications; adjust hydraulic flow parameters to match different working tools and avoid overload operation.

Travel & Transfer Precautions

1. Retract the working arm and lower the bucket close to the ground during walking, keep the body center of gravity stable, and avoid high-speed walking and sharp turning.
2. Slow down when passing slopes, uneven roads and soft ground; avoid long-distance rapid driving to reduce track wear and chassis loss.
3. Fix the machine firmly with professional tools during long-distance transportation and transfer to avoid sliding and collision damage.

 Shutdown & Daily Maintenance

1. Standard Shutdown: Park the machine on flat ground, lower all working devices to the ground, turn off the engine after 1–2 minutes of idle cooling, and cut off the power supply.
2. Daily Maintenance: Clean soil and sundries on tracks and chassis after operation; check pipeline tightness and liquid level status; lubricate connecting pins and rotating parts regularly.
3. Regular Maintenance: Replace engine oil, filter elements and hydraulic oil regularly according to the official cycle; inspect hydraulic system pressure and track wear; repair and replace worn bucket teeth and vulnerable parts in time.
4. Long-Term Storage: Clean the whole machine thoroughly, perform anti-rust treatment on metal parts, park in a dry and ventilated environment, and start the machine regularly for idle operation to avoid component aging.
