The fourth trick: apply "sunscreen and makeup base" to the structural components
Exposure to the scorching sun can accelerate the oxidation of metal structures and the aging of seals. A common practice among experienced drivers is to conduct a comprehensive lubrication of moving parts such as pin shafts and bearings weekly, using high-temperature resistant lithium-based grease. They also apply anti-rust protective agents to the exposed hydraulic cylinder piston rods and affix a reflective heat-insulating film to the top of the cab and the outside of the boom. "This film can reduce the temperature inside the cab by 5°C and prevent the machine casing from discoloring due to exposure to the sun," Master Li added. After rain, the chassis should be washed promptly to avoid mud agglomerating and corroding metals under high temperatures.
Fifth move: Develop a schedule for "staggered operations"
Reasonably scheduling homework time is more effective than any maintenance. The three masters all suggest adopting a "early departure and late return" schedule: concentrated work from 5am to 10am and 4pm to 8pm, and rest during the high temperature period at noon. This period of time is perfect for daily inspections, killing two birds with one stone. "Master Wang emphasized that when stopping the machine, do not immediately turn off the engine. Instead, let it idle for 3-5 minutes to gradually cool down the turbocharger and other components." Running and stopping suddenly is the most harmful to the machine, just like a person cannot sit down immediately after intense exercise
High temperature operations are like a protracted battle, testing not only the performance of equipment, but also the maintenance wisdom of operators. When you find that the hydraulic oil temperature continues to exceed 90 ℃, the engine idles unstably, or there is an inexplicable noise, these are all "distress signals" sent by the machine. Remember, a timely maintenance can avoid ten times the repair cost, and a small habit can extend the service life of equipment by three years.
