Do not operate the hydraulic system until the hydraulic system oil has become hot. Otherwise, the hydraulic components will be damaged, and a blasting accident will occur when the oil is severe. The forklift should control the speed while driving, keep the distance and avoid emergency braking. The braking interval in the cold season is about 2 times longer than usual. It is forbidden to turn sharply and reduce the impact force during cornering to prevent the rigid structural parts from breaking.
To do the season maintenance of the equipment, check the freezing point of the antifreeze to 5 °C lower than the local minimum temperature; make the thermostat opening temperature around 82 °C; increase the battery electrolyte density to 1.280g/cm3; adjust the machine in time Each part uses oil. It is necessary to install insulation measures for equipment working in the field. If necessary, install engine oil preheating device, and start the engine regularly to preheat the working systems of each department.
After starting the engine normally, there must be enough warm-up time to run at low speed and light load until the oil in the engine, transmission, hydraulic system and final drive heats up. When the equipment is working, it is slow to operate the bucket, blade and various devices. It is forbidden to impact, scrape, shovel and push the big throttle. The key requirements are "stable" and "slow". Winter is the season of high accidents, accounting for about 80% of the total accidents in the year, and the accidents caused by operational errors in winter are more than 65%. If the temperature is below -15 °C, the engine cannot be operated immediately after starting, but the engine should be operated at 1000-1100r/min for 10-15min, and the transmission is in neutral. Therefore, it is necessary to regularly check the rigid connection of the forklift machine and the main load-bearing parts.
