How Should Forklifts Be Maintained? Worth Collecting

I. Daily Maintenance Remove oil stains and dust from the vehicle body, with special attention to cleaning the radiator fins. Check tires: verify tire pressure is normal (for solid tires, check for wear), and remove foreign objects from tread patterns. Fluid checks: Engine oil/Hydraulic oil: Oil level should be between the scale marks (check when engine is cold). Coolant: Keep the expansion tank at least 1/2 full. Brake fluid: Check whether the fluid level in the reservoir meets the required standard. Key component checks: Chain lubrication: Lubricate the mast chains with dedicated lubricating oil. Leak inspection: Check the engine, hydraulic pump, and cylinder bottoms for any oil stains. Instrument panel warning lights: Confirm no fault indications. II. Periodic Maintenance (by hours/mileage) 50-hour maintenance: Tighten all exposed bolts (especially wheel hub and mast bolts). Clean the air filter (shorten the interval in dusty environments). 250-hour maintenance (or monthly): Replace engine oil and oil filter (for diesel engines, oil rated CI-4 or above is recommended). Check transmission oil level (for vehicles with hydrodynamic transmission). Adjust brake pedal free travel (10-15mm is optimal). 500-hour maintenance (or quarterly): Replace the hydraulic oil filter (be sure to release system pressure first). Check hydraulic oil contamination level (particle counter testing is recommended). Apply grease to mast guide rails (use molybdenum disulfide lithium-based grease). 1000-hour maintenance (or semi-annually): Replace hydraulic oil (ISO VG32 or VG46 anti-wear hydraulic oil). Inspect kingpin wear on the steering axle (replace if radial clearance > 2mm). Test the lowering speed of the lifting system (should be ≤ 600mm/s at full load). III. Seasonal Maintenance Winter (when temperature < 5°C): Replace with low-pour-point hydraulic oil (e.g., L-HV32). Adjust battery electrolyte specific gravity to 1.28-1.30. Use diesel fuel rated -10# or lower for diesel vehicles. Summer (when temperature > 30°C): Clean dust from the radiator (can use compressed air to blow through in reverse direction). Check fan belt tension (depression should be 10-15mm when pressed). IV. Long-Term Storage Maintenance Lower the forks to the lowest position. Disconnect the battery negative terminal (charge the battery once a month). Inflate tires to 120% of standard pressure. Run the hydraulic system for 5 minutes every week. V. Professional Maintenance Recommendations Every 2000 hours, professional personnel should perform: Hydraulic pump pressure test (ensure it is within ±5% of rated pressure). Steering system angle calibration. Mast deformation inspection (measure using a laser level). Replacement intervals for key components: Hydraulic oil: 2000 hours or 2 years. Transmission oil: 4000 hours (not required for electric vehicles). Brake pads: Must be replaced when worn to 3mm. VI. Maintenance Record Template Date | Hours | Maintenance Content | Parts Replaced | Next Maintenance Plan Example: 1250 | Replaced hydraulic oil/filter | HV46 oil 20L | 2000-hour system inspection Notes: Before operation, be sure to cut off the power supply (for electric vehicles) or turn off the engine (for internal combustion vehicles). Pressure must be released before performing maintenance on the hydraulic system. Do not mix different types of grease (different grades may cause chemical reactions).
