Before the Across wrench is officially put into use, it has to go through layers of inspection and screening, the most basic of which is the appearance inspection. It can also be said that only after there is no problem with the appearance, can further quality inspection be carried out, and the inspection can be continued. The waste products appearing in the process are picked out by the team and inspected by the inspector for review and disposal.Inspectors conduct sampling inspections according to the prescribed inspection items.

If unqualified products are found during sampling inspection, the inspection lot shall be returned to the team for self-inspection, and the unqualified products shall be picked out before resubmission for inspection. Inspectors supervise the production process. If the blanks fail to meet the quality standards, they have the right to make adjustments, and mass production can only be made after the adjustments are qualified. The results of the surface oxide scale inspection of tire wrenches are used for workshop process control, and are not used as batch qualification judgments.If the blank has residual burrs that exceed the specified requirements, rework and use a grinding wheel to grind out the excessive burrs.


A small amount of non-conforming products in other forms shall be treated as scrap. If batches of non-conforming products are in batches, they shall be disposed of after review by the relevant departments. After the inspection is completed, fill in the inspection record according to the quantity. There are more and more people who own cars. Knowing more about common sense of tire disassembly and assembly will help us a lot in our daily use. I have introduced how to use a cross wrench to remove a tire. Today I will talk about how to install it.Replace the removed tire with the spare tire, and then tighten the four screws by hand until they cannot be screwed.


Replace the removed tire with the spare tire, install the spare tire, adjust the angle to align the bolt holes, and install the uppermost bolt first. Hold the tire with your hands or feet, install the remaining bolts, and use the tire wrench sleeve to increase the force so that the tire cannot shake. Lower the jack until the tire touches the ground lightly, and tighten the screw with a socket wrench.Screw on the wheel lock bolts in diagonal order. Do not screw the screws clockwise or counterclockwise. It is best to keep the same number of turns of each screw when screwing the screws to ensure that the screws are evenly stressed. The final step is to pack the replaced tires, tools and warning signs, and complete the entire tire replacement procedure. At the same time, remember to send the faulty tire in time for repair.
