 Pre-Operation Inspection
Before starting the vehicle, conduct a comprehensive inspection to eliminate potential safety hazards and ensure normal operation, in line with the safety operation specifications of heavy-duty tractors:

1. Exterior & Chassis: Check the tire pressure and wear condition of all tires, ensure wheel nuts are fastened; inspect the traction saddle, traction pin and connecting bolts for looseness, deformation or wear; check the drive shaft, axle and chassis bolts for tightness and damage; confirm the ground clearance is normal, and remove obstacles on the driving path to avoid tire or chassis damage during driving; check the integrity of the differential lock and its pipeline.
2. Fluid Inspection: Check the levels of engine oil, coolant, fuel and brake fluid to ensure they meet the standard; drain the accumulated water in the fuel filter in time; inspect the oil pipeline and brake pipeline for tightness, and check for oil leakage or air leakage; ensure the oil temperature and water temperature are within the normal range before operation, especially in cold areas; check the hydraulic oil level of the cab suspension system.
3. Cab & Electrical System: Test the vehicle lights, horn, wiper, automatic headlight and automatic rain wiper to ensure all electrical equipment works normally; check the airbag seat, suspension system and steering system for normal operation; confirm the parking brake (EPB electronic brake) is in effective braking state; adjust the rearview mirror and central control screen, and check the 360 panoramic camera and blind spot monitoring function to ensure good driving vision; check the traction saddle locking device to ensure it is locked reliably; test the one-button start and keyless entry functions.

 Vehicle Starting & Daily Driving

1. Use the keyless entry function to enter the cab, press the one-button start switch to turn to the "ON" position, wait for the vehicle self-inspection to complete (no fault alarm), then press and hold the one-button start switch to start the engine. For the AMT automatic gearbox version, ensure the gear is in neutral before starting; start the engine in a well-ventilated area to avoid exhaust pollution.
2. After starting, let the engine idle for 3–5 minutes to warm up, observe the instrument data (engine speed, oil pressure, water temperature) to ensure all indicators are normal. In low-temperature areas, preheat the engine to 30–40℃ before starting; do not start the engine with full load when the water temperature and oil temperature do not meet the requirements, to avoid damaging the powertrain.
3. Release the parking brake (EPB electronic brake), confirm the gear is in neutral (for automatic gearbox, switch to D gear), step on the accelerator gently to start smoothly, avoiding violent acceleration and harsh gear shifting, especially when pulling a heavy-load trailer to prevent drive shaft or tire slipping; honk the horn before starting to warn surrounding personnel.
4. Maintain a stable speed during driving: the maximum speed on highways shall not exceed 90km/h, and the speed on ordinary roads shall be controlled within 60km/h. For long downhill sections, use low gears and engine brake to avoid frequent braking, which may cause brake failure; do not change direction or shift gears when the vehicle is moving at high speed, and keep a safe distance from the vehicle in front; use the ACC adaptive cruise function appropriately to reduce driving fatigue.
5. When driving on muddy, snowy or slippery roads, turn on the differential lock to improve wheel grip and passability; avoid sharp turns at high speed to prevent rollover. For steep slopes, use low gears to ensure sufficient power and avoid slipping; when climbing, maintain a stable speed and do not shift gears frequently; use the HSA hill-start assist function when starting on slopes to prevent slipping.
6. During long-distance driving, pay attention to the fuel level and instrument prompts, and refuel in advance when the fuel is low; pay attention to the prompts of the intelligent fault diagnosis system, and deal with abnormal conditions in time; check the trailer connection status regularly during driving to ensure safe traction; use the PPC predictive driving function to further improve fuel economy.

 Trailer Connection & Disconnection Operation

1. Trailer Connection: Drive the tractor to the front of the trailer, keep the tractor and trailer in a straight line, and slowly approach the trailer until the traction pin is aligned with the traction saddle; lower the tractor's suspension appropriately to make the traction pin insert into the traction saddle; lock the traction saddle locking device, and check to confirm it is locked reliably; connect the trailer's air circuit and circuit connectors, and test the trailer's lights and brakes to ensure they work normally; check the trailer's tire pressure and connection bolts, and confirm there is no looseness; use the 360 panoramic camera to check the surrounding environment to avoid blind spots.
2. Trailer Disconnection: Drive the tractor and trailer to a flat, solid and open area, shift to neutral gear, and firmly pull the parking brake of the tractor (EPB electronic brake) and trailer; disconnect the trailer's air circuit and circuit connectors, and place the connectors in a clean and dry place to avoid pollution; lift the tractor's suspension to separate the traction saddle from the trailer's traction pin; slowly drive the tractor forward to separate it from the trailer, and park the tractor and trailer in a safe area respectively; place wheel blocks under the trailer's wheels to prevent slipping.

 Post-Operation Maintenance

1. Clean the dust on the cab, chassis and traction saddle to prevent dust accumulation from affecting the service life of the vehicle; clean the air filter regularly to ensure engine intake smoothness, especially in dusty areas; clean the 360 panoramic camera lens and sensor to ensure clear vision and normal function; clean the residual dirt on the trailer connection part.
2. Check the levels of all oils and liquids again, replenish fuel, engine oil, coolant and brake fluid in time; check for oil leakage, air leakage and loose bolts (focus on chassis, powertrain and traction system), and tighten or repair them immediately if any problems are found; when inflating the tires, do not stand in front of the tires to avoid injury from explosion; check the wear condition of the brake pads and tires.
3. Park the vehicle in a dry, ventilated and flat area, turn off the engine, pull the parking brake (EPB electronic brake) tightly, and put the gear in neutral. If the vehicle is parked for a long time, cover the cab and traction saddle to avoid dust and corrosion; turn off the main power switch and close the doors and windows; disconnect the power supply of the trailer if it is not connected; retract the cab suspension to the appropriate position.
4. Carry out regular maintenance according to the vehicle manual: replace engine oil, filter elements (air filter, oil filter, fuel filter) and gear oil regularly according to the maintenance cycle (engine 120,000 kilometers, transmission and drive axle 240,000 kilometers); check the wear condition of tires, brake pads and transmission parts, and conduct comprehensive inspection and maintenance of the powertrain, traction system and brake system to ensure the long-term stable and efficient operation of the vehicle; when maintaining the vehicle, support the lifted parts firmly to avoid accidents.
