Summary of Precautions for Initial Use of Rough Terrain Forklifts

Summary of Precautions for Initial Use of Off-Road Forklifts Off-road forklifts, due to their strong passability and adaptability, are widely used in complex terrains such as construction sites, mines, and farms. To ensure safe operation and extend equipment service life, special attention should be paid to the following matters during the initial use phase: I. Pre-Use Inspection and Preparation Comprehensive Equipment Inspection: Check tires (inflation pressure or solid tire condition) and wheel hub bolts for tightness; confirm that hydraulic oil, engine oil, coolant, and brake fluid are within standard ranges; check the fuel system (diesel/gasoline) for proper operation and no leaks; test lights, horn, and dashboard for normal functioning. Lubrication and Tightening: Check that all lubrication points (such as steering system, drive shaft, lift chains, etc.) have been greased; re-tighten key bolts (such as those on the fork carriage, drive axle, suspension system, etc.). Familiarize with the Operation Manual: Different brands and models of off-road forklifts may have different operating methods. Be sure to read the manual to understand control methods (such as gear shifting, hydraulic operations, etc.). Personal Protective Equipment: Wear safety helmets, non-slip shoes, reflective vests, and other protective gear; ensure the operator holds a valid forklift operation certificate (if applicable). II. Starting and Trial Operation Cold Start Precautions: Diesel engines require preheating (some models need to wait for the preheat indicator light to go out before starting); after starting, run at idle speed for 1-2 minutes to allow the oil to fully lubricate the engine. Trial Operation Checks: Test whether the steering system is flexible and free of sticking; test whether hydraulic lifting and tilting functions are smooth and free of abnormal noise; check whether the braking system (foot brake, hand brake) is responsive. Avoid Incorrect Operations: Do not run the engine at high RPM when cold to avoid engine wear; do not idle for extended periods to prevent carbon buildup. III. Key Points for Initial Operation Break-in Period (First 50 Hours): Avoid full-load operations; it is recommended that the load not exceed 70% of the rated capacity; avoid prolonged high-speed driving or sudden acceleration and braking; stop and inspect every 2-3 hours of work to prevent overheating. Operation on Complex Terrain: When driving on mud, sand, slopes, or other environments, reduce speed and avoid sharp turns; keep the forks low when going uphill or downhill, and reverse down slopes when necessary to improve stability; avoid sudden braking on soft ground to prevent getting stuck or tipping over. Load Management: Cargo should be evenly distributed to avoid offset loads; ensure the forklift is stationary when lifting or lowering loads, and never lift or lower while driving; do not overload to prevent damage to the hydraulic system. IV. Safety Precautions Operational Safety: When driving, keep the forks no more than 30 cm above the ground to avoid affecting visibility and stability; slow down when turning to prevent tipping; do not carry passengers (unless a dedicated safety seat is installed). Emergency Handling: If the hydraulic system fails, stop immediately and slowly lower the forks; if there is a risk of tipping, do not jump out of the vehicle—grip the steering wheel firmly and lean your body in the opposite direction. Environmental Safety: Turn on lights when operating at night or in low visibility conditions; be aware of blind spots when working in confined spaces, and arrange for a spotter if necessary. V. Initial Maintenance and Care Post-Break-in Maintenance: Replace engine oil, oil filter, and hydraulic oil filter element (as per manufacturer requirements); check tire wear and adjust tire pressure (for pneumatic tires). Daily Maintenance: Check oil, water, and electrical systems daily (fuel, engine oil, coolant, battery); clean the radiator to prevent dust blockage from affecting heat dissipation; check lubrication of moving parts such as chains and bearings. Long-Term Storage: If the forklift will not be used for an extended period, drain the fuel or add a stabilizer to prevent corrosion in the fuel lines; start and run the machine regularly (at least once a month) to prevent battery discharge. VI. Common Problems and Solutions Difficulty Starting: May be caused by a discharged battery or fuel system issues; check battery voltage and clean the fuel filter. Weak Hydraulic System: May be due to insufficient hydraulic oil or a clogged filter element; replenish hydraulic oil or replace the filter element. Abnormal Noise: May be caused by a loose drive shaft or worn bearings; stop and inspect, then tighten or replace components. Heavy Steering: May be due to insufficient steering hydraulic oil or low tire pressure; replenish hydraulic oil or adjust tire pressure. Conclusion The initial use phase of an off-road forklift is a critical period for equipment adaptation and break-in. Correct operation and maintenance can significantly improve equipment lifespan and operational safety. Be sure to follow manufacturer guidelines, perform regular maintenance, and drive cautiously in complex environments to ensure the safety of both personnel and machinery.
