# Summary of Precautions for the Initial Use of Rough Terrain Forklifts

Summary of Precautions for the Initial Use of Rough Terrain Forklifts Rough terrain forklifts are widely used in complex terrain environments such as construction sites, mines, and farms due to their strong passability and adaptability. To ensure safe operation and extend equipment service life, the following precautions must be paid special attention to during the initial use stage: I. Pre-Use Inspection and Preparation Comprehensive equipment inspection: Check whether tires (pneumatic pressure or solid tire condition) and wheel hub bolts are tightened; confirm whether hydraulic oil, engine oil, coolant, brake fluid, etc. are within standard ranges; check whether the fuel system (diesel/gasoline) is normal and leak-free; test whether lights, horn, and instrument panel are working properly. Lubrication and tightening: Check whether all lubrication points (such as steering system, drive shaft, lifting chain, etc.) have been filled with lubricating oil; re-tighten key bolts (such as fork carriage, drive axle, suspension system, etc.). Familiarize yourself with the operation manual: Different brands and models of rough terrain forklifts may have different operating methods. Be sure to read the manual to understand the control methods (such as gear shifting, hydraulic operation, etc.). Personal protection: Wear protective equipment such as safety helmets, anti-slip shoes, and reflective vests; ensure the operator holds a valid forklift operator certificate (if applicable). II. Startup and Trial Operation Cold start precautions: Diesel engines need preheating (some models require waiting for the preheat indicator light to turn off before starting); after starting, run at idle for 1-2 minutes to allow the oil to fully lubricate the engine. Trial operation inspection: Test whether the steering system is flexible and free of jamming; test whether the 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 at high speed with a cold engine 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 operation; it is recommended that the load not exceed 70% of the rated capacity; avoid prolonged high-speed driving or sudden acceleration and sudden braking; stop every 2-3 hours of work for inspection to prevent overheating. Operation on complex terrain: When driving on mud, sand, slopes, and other environments, reduce speed and avoid sharp turns; when going uphill or downhill, keep the forks low, and reverse downhill when necessary to improve stability; avoid sudden braking on soft ground to prevent getting stuck or rollover. Load management: Cargo should be evenly distributed to avoid off-center loading; ensure the forklift is stationary when lifting or lowering cargo, and do not lift or lower while driving; do not overload to prevent hydraulic system overload damage. IV. Safety Precautions Operational safety: When driving, the fork height above ground should not exceed 30 cm to avoid affecting visibility and stability; slow down when turning to prevent rollover; do not carry passengers (unless a dedicated safety seat is available). Emergency handling: If the hydraulic system fails, stop immediately and slowly lower the forks; if there is a risk of tipping, do not jump off, but grip the steering wheel firmly and lean your body in the opposite direction. Environmental safety: Turn on lights at night or when visibility is low; pay attention to blind spots when working in narrow spaces, and arrange a spotter when necessary. V. Initial Maintenance Post break-in maintenance: Replace engine oil, oil filter, and hydraulic oil filter element (according to manufacturer requirements); check tire wear and adjust tire pressure (pneumatic tires). Daily maintenance: Check oil, water, and electricity daily (fuel, engine oil, coolant, battery); clean the radiator to prevent dust blockage from affecting heat dissipation; check the lubrication of moving parts such as chains and bearings. Long-term storage: If not used for a long time, drain the fuel or add a stabilizer to prevent fuel line corrosion; start and run periodically (at least once a month) to prevent battery discharge. VI. Common Problems and Solutions Difficulty starting: May be caused by a low battery or fuel system problems. Check battery voltage and clean the fuel filter. Weak hydraulic system: May be due to insufficient hydraulic oil or a clogged filter element. Add hydraulic oil or replace the filter element. Abnormal noise: May be caused by a loose drive shaft or worn bearings. Stop the machine for inspection and tighten or replace components. Heavy steering: May be due to insufficient steering hydraulic oil or low tire pressure. Add hydraulic oil or adjust tire pressure. Summary The initial use stage of a rough terrain forklift is a critical period for equipment adaptation and break-in. Correct operation and maintenance can greatly improve equipment life and work safety. Be sure to follow the manufacturer's guidance, perform regular maintenance, and drive cautiously in complex environments to ensure the safety of both people and machinery.
