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 FAW Jiefang J7 Tractors, especially suitable for long-distance, heavy-load and cross-border logistics transportation:

1. Exterior & Chassis: Check the tire pressure and wear condition of all tires (focus on the dual rear drive axles), ensure wheel nuts are fastened; inspect the traction saddle, traction pin and connecting bolts for looseness, deformation or wear; check the drive shaft, dual rear axles and chassis bolts for tightness and damage, especially to prevent loosening caused by bumpy roads under heavy-load conditions; 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 (inter-wheel and inter-axle) and its pipeline, and ensure it can work normally on slippery, muddy and mountain roads; check the fuel tank, air storage tank and workbench for looseness; clean the LED headlights, camera lens and electronic rearview mirror to avoid affecting vision due to dust
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 low-temperature and plateau areas; check the hydraulic oil level of the cab suspension system and the heat dissipation system for normal operation, to adapt to the heat generation of the engine under heavy-load conditions
3. Cab & Electrical System: Test the vehicle lights (especially full LED headlights), 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 is in effective braking state (especially important for heavy-load vehicles); adjust the electronic rearview mirror and central control screen, and check the 360 panoramic camera, blind spot monitoring, driver fatigue monitoring and other functions to ensure good driving vision and safety protection (especially important for urban and long-distance driving); check the traction saddle locking device to ensure it is locked reliably; test the one-button start function and intelligent fault diagnosis system if equipped; check the storage battery status and circuit connections; check the 60W fast charging, 1000W power supply and other functions if equipped

Vehicle Starting & Daily Driving

1. Enter the cab, turn the key to the "ON" position (or press the one-button start switch), wait for the vehicle self-inspection to complete (no fault alarm), then start the engine. For the AMT automatic gearbox version, ensure the gear is in neutral before starting; for heavy-load starting, avoid starting with full load to protect the powertrain
2. After starting, let the engine idle for 2–3 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 25–35℃ 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 (especially important for 6×4 heavy-load tractors)
3. Release the parking 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 (49–60 tons) to prevent drive shaft or tire slipping; honk the horn before starting to warn surrounding personnel, which is more important in areas with poor vision such as urban narrow roads and logistics parks
4. Maintain a stable speed during driving: the maximum speed on highways shall not exceed 100km/h, and the speed on ordinary roads and urban roads shall be controlled within 45–60km/h; when driving on mountain roads and hills, reduce the speed appropriately to ensure safety. For long downhill sections, use low gears and engine brake to avoid frequent braking, which may cause brake failure (especially critical for heavy-load vehicles); 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 cruise control function appropriately on flat roads to reduce driving fatigue and optimize fuel consumption; the AMT version can use the manual mode to further optimize fuel consumption and adapt to complex road conditions such as mountain roads
5. When driving on muddy, snowy or slippery roads, turn on the inter-wheel differential lock and inter-axle differential lock to improve wheel grip and passability; avoid sharp turns at high speed to prevent rollover (the 6×4 dual rear drive configuration has a higher center of gravity under heavy load, so special attention should be paid to driving safety). For steep slopes and plateau areas, use low gears to ensure sufficient power and avoid slipping; when climbing, maintain a stable speed and do not shift gears frequently; use the hill-start assist function when starting on slopes to prevent slipping
6. During long-distance driving and cross-border logistics distribution, pay attention to the fuel level and instrument prompts, and refuel in advance when the fuel is low (a single tank of fuel can support 3000–3500 kilometers of driving); 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 under heavy-load conditions; avoid overloading to prevent damage to the powertrain and dual rear axles; use the parking air conditioning appropriately during rest to save fuel; clean the camera lens, headlights and electronic rearview mirror regularly to avoid affecting vision due to dust

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 (pay attention to the alignment accuracy under heavy-load trailer conditions); 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, especially in narrow areas and logistics parks
2. Trailer Disconnection: Drive the tractor and trailer to a flat, solid and open area (ensure the ground can bear the heavy load of the tractor and trailer), shift to neutral gear, and firmly pull the parking brake of the tractor 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, which is more important on slopes (heavy-load trailers are more likely to slip)

 Post-Operation Maintenance

1. Clean the dust on the cab, chassis, traction saddle and workbench to prevent dust accumulation from affecting the service life of the vehicle; clean the air filter regularly to ensure engine intake smoothness (especially important for heavy-load engines); clean the 360 panoramic camera lens, LED headlights, electronic rearview mirror and sensor to ensure clear vision and normal function; clean the residual dirt on the trailer connection part; clean the auxiliary toolbox and arrange the tools neatly
2. Check the levels of all oils and liquids (engine oil, coolant, fuel, brake fluid) again, replenish in time; check for oil leakage and loose bolts (focus on chassis, powertrain, dual rear axles 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 (heavy-load and long-distance driving requires more frequent inspection); check the air storage tank and soft connection part for looseness; check the fuel filter system and clean or replace it in time; inspect the heat dissipation system and clean the radiator to ensure normal heat dissipation (adapting to the heat generation of the engine under heavy-load conditions)
3. Park the vehicle in a dry, ventilated and flat area, turn off the engine, pull the parking 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; clean the interior storage space, living small table and other components
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 100,000 kilometers, transmission and dual rear axles 150,000–200,000 kilometers); check the wear condition of tires, brake pads and transmission parts, and conduct comprehensive inspection and maintenance of the powertrain, traction system, brake system and heat dissipation system to ensure the long-term stable and efficient operation of the FAW Jiefang Tractor; when maintaining the vehicle, support the lifted parts firmly to avoid accidents
