Operation Guidelines
Pre-Operation
Inspect engine oil, coolant, hydraulic fluid, and fuel levels.
Check track tension, undercarriage components, and bucket teeth for wear.
Test lights, alarms, and safety interlocks; ensure cab windows and mirrors are clean.
Starting & Operation
Enter the cab, fasten the seatbelt, and start the engine; idle for 3–5 minutes to warm up.
Select the desired work mode (standard, heavy, or economy) via the control panel.
Operate the joysticks smoothly to control boom, arm, bucket, and swing functions.
Maintain stable travel speed; avoid sudden turns or high-speed operation on slopes.
Monitor gauges for temperature, pressure, and fuel consumption during operation.
Post-Operation
Park the machine on level ground, lower the bucket to the ground, and idle for 2–3 minutes.
Turn off the engine, disconnect the battery, and lock the cab.
Clean the machine and inspect for damage or leaks; replenish fluids if needed.
FAQ
