# Precautions for Tractor Use (Professional Operating Specifications)

I. Pre-Start Inspection (Mandatory) Five Essential Fluid Checks Engine Oil Dipstick: Oil level between the upper and lower marks (cold engine); Hydraulic Oil: Oil surface visible in sight glass at oil temperature of 20°C; Coolant: Expansion tank level 3-5 cm below filler neck; Fuel: Drain water from drain valve until clean fuel flows out (diesel engine); Brake Fluid: Reservoir level not below MIN line. Critical Component Verification Tire Pressure: Refer to door frame calibration value ±5%; Drive Belt: 10 mm deflection under thumb pressure is normal; Protective Devices: ROPS/FOPS structures free from deformation. II. Starting Procedures (Avoiding Cold-Start Damage) Diesel Engine Starting Sequence Turn key to ON position and wait for preheat indicator to go out (approx. 15 seconds); Depress clutch fully to the floor (manual transmission models); Starting time ≤10 seconds per attempt, interval ≥30 seconds; Idle for 3-5 minutes (operation permitted when coolant temperature ≥40°C). Prohibited Actions Tow-starting (risk of ECU damage); More than 3 consecutive starting attempts (battery over-discharge); High-throttle warm-up on cold engine (abnormal piston ring wear). III. Driving Operation Essentials Golden Rules of Gear Shifting Operating Condition | Gear Selection | Engine Speed Control Heavy-Load Starting | Lowest gear (creeper gear) | 1500-1800 rpm Field Operation | Economy gear (green zone) | 80% of rated speed Road Travel | Highest gear (without overspeeding) | ≤ Rated speed Hydraulic System Operation Fork Lifting/Lowering: Confirm no obstacles within 2 meters before operation; Attachment Switching: Must be performed after complete pressure release; End Positions: Leave 10 cm margin (to avoid impact). IV. Response to Special Operating Conditions Slope Operations Uphill: Keep load center of gravity between front wheels and rear axle; Downhill: Shift to low gear in advance (neutral coasting prohibited); Side Slope: Anti-rollover device mandatory when slope >15°. Harsh Environments Muddy Terrain: Engage differential lock (only when driving straight); Sandy Terrain: Deflate tires to 70% of standard pressure; Low Temperatures: Use fuel preheating system below -15°C. V. Safety Warnings (Lessons Learned from Past Incidents) Ten Absolute Prohibitions Performing maintenance with engine running (rotating parts can cause severe injury); Standing under raised lift arms (risk of hydraulic failure); Cornering at excessive speed (high rollover risk); Overloading during transport (permanent frame deformation); Removing safety guards (entanglement accidents); Driving across slopes (prohibited when >10°); Sudden clutch release (transmission shock); Inspecting fuel lines with open flames (explosion hazard); Carrying passengers in non-passenger positions (no protective equipment); Operating at night with incomplete lighting (collision accidents). VI. Shutdown Procedures (Key to Extending Service Life) Proper Engine Stop Sequence Unload all hydraulic functions (return control levers to neutral); Idle for 2 minutes (turbocharged models); Turn off master power switch (to prevent electrical leakage). Long-Term Storage Guidelines Fill fuel tank completely and add fuel stabilizer; Fully retract hydraulic cylinders (rust prevention treatment); Keep tires off the ground or rotate periodically (to prevent flat-spotting). VII. Smart Equipment Usage Autonomous Operation Precautions Pre-operation calibration: Boundary error <3 cm; Emergency situations: Emergency stop button test (once per month); Signal loss: Verify automatic switchover to manual mode. Display Screen Operating Restrictions Do not adjust complex parameters while driving; System freeze: Press and hold power button for 15 seconds; Waterproof and dustproof (IP rating verification). Expert Recommendation: Establish a "Tractor Health Record" to document every fault code, maintenance data, and oil change record. For advanced models, remote monitoring systems are recommended to receive real-time engine health alerts.
