先核对企业与产品身份 Check company and product identity first
采购凿岩机时，应核对企业名称、官网、联系方式、产品型号、铭牌和包装信息，避免只依据一张图片或一个相似名称判断厂家。 Verify company name, website, contact, model, nameplate and packaging. A photograph or similar name alone does not identify a manufacturer.
再核对真实资料和参数边界 Then check documentation and specification limits
可靠的产品页面应区分已确认参数、参考参数和暂不能确认的信息。真实产品照片、装配检验和包装资料可辅助判断，但最终仍以订单确认文件为准。 Reliable product pages distinguish confirmed, reference and unknown information. Product photos, assembly inspection and packaging records help, but confirmed order documents govern.
把配套和售后写清楚 Document accessories and after-sales scope
气腿、注油器、钎具、气水管、备件、包装、运输和售后范围都应逐项确认。 Confirm air leg, lubricator, tooling, hoses, spares, packaging, transport and after-sales scope individually.
