升降机在更换新油气滤芯时，固定油气滤芯底部安装集流罩的螺栓（直径8 mm）脱落。为了节约成本和节省时间，决定将螺栓重新焊上，先用湿棉纱覆盖在油气滤芯底部待焊螺栓的位置周围，再用直径2.5 mm的焊条小电流进行点焊。 
Lifts lift manufacturers analysis of oil and gas in the replacement of a new filter, the filter is installed at the bottom of a fixed oil and gas manifold cover screw (diameter 8 mm) off. In order to save costs and save time, decided to re-weld the bolts, first covered with a wet cotton yarn around the location of oil and gas at the bottom of the filter to be welded the bolts, and then a 2.5 mm diameter spot welding electrodes small current.
        
建议拆下升降机上旧的油气滤芯时，发现密封垫牢固地粘在油气滤芯安装筒上。放出油液，铲除密封垫，再用油将密封垫的碎屑冲洗干净。这样做不仅费时，而且浪费油液，还不能保证完全清除密封垫碎屑。大家可以用铁丝制作1个简易的十字型支架，将垃圾袋套好后，再将其放入油气筒中，确定其密封牢固后即可清除密封垫。
Lift manufacturer recommends removing the lift on the old oil and gas filters, we found that the gasket is firmly glued to the oil and gas canister filter installation. Release oil, eradicate gaskets, then oil will seal debris rinse.This is not only time-consuming, and waste oil, it can not guarantee complete removal of seal debris. We can make a simple wire cross-shaped bracket, the trash bag after a good set, and then put it in the oil and gas cylinder, make sure to clear it after the gasket seal securely.
