After how many working hours should the first-level maintenance of field vehicles be performed?

The "Review Textbook for Operators of Specialized Internal Vehicles" mentions that the first-level maintenance of field vehicles should be performed after 250 working hours. Below is the relevant introduction: Concept of first-level maintenance of equipment: Mainly performed by operators with the assistance of maintenance workers, this maintenance is scheduled every two months of operation (for two-shift systems) or as planned. The maintenance duration is generally 4 to 8 hours. Scope and content of first-level maintenance of equipment: Based on the usage of the equipment, partial disassembly, cleaning, and repair of components are carried out. Proper adjustments are made to the fitting clearances of various parts of the equipment. Cleaning of felt, yarn, and oil filters; clearing of oil passages and pipelines, replenishing lubricating oil and grease, and making up for any deficiencies to ensure no yellowing. All operating mechanisms, various stops, limit switches, etc., are adjusted to be sensitive and reliable, and all dust and chip prevention devices are cleaned and repaired to be fully functional.
Primary maintenance for field vehicles is generally performed after 200 to 250 working hours. As a veteran worker with decades of experience in this field, let me share some insights. In the past, maintenance intervals were shorter, typically around 150 hours, because older vehicles were more prone to breakdowns. However, with updated equipment nowadays, most manufacturer manuals recommend a 250-hour interval, though this can vary depending on the vehicle model and usage intensity. During maintenance, basic checks include verifying proper oil levels, assessing tire wear, and testing brake responsiveness—simple measures to prevent major issues. Delaying maintenance beyond 300 hours, for example, often leads to brake failure or engine overheating, which isn't just an inconvenience but can cause serious accidents. At our factory, someone recently postponed maintenance, resulting in a forklift breaking down and halting operations for half a day, causing significant losses. So never slack off—follow the manual's recommendations as the golden standard, with safety as the top priority.
Primary maintenance should be completed after 200 to 250 working hours. As a young mechanic who spends all day in the repair shop doing this job, I can honestly say maintenance is no small matter—it includes changing the oil, replacing filters, and inspecting wiring. Why stick to the schedule? Because industrial vehicles work multiple shifts a day, fluids degrade faster, and increased wear can lead to blowouts or failure to start. I've seen many customers delay maintenance beyond 250 hours, only to discover burnt wiring that cost far more to fix. I recommend preparing for a shop visit around 200 hours of use. Operators should routinely log working hours themselves instead of relying on reminders. Using an app to track time is also a modern way to avoid oversights. Safety-wise, vehicles breaking down in the shop and causing injuries is common—I always advise against skimping on this small expense, as prevention is far more cost-effective than repairs.
