How to deal with the pressure gauge pointer falling off

1. Check the positioning screw of the gauge pointer. Normally, if the pressure gauge pointer falls, you first need to check the positioning screw. If the screw is loose, replace the pressure gauge pointer and tighten the screws in time. Be careful not to over-tighten or over-loosen the screws.

2. Replace the dropped pointer of pressure gauge. If the problem persists after the set screws are tightened, could consider change pointers and screws. At this time, the pointer of the same specification should be selected and replaced by a professional to avoid new failures caused by improper operation.

3. If the above two methods cannot solve the problem, you need to further pressure gauge inspection, check whether the internal parts of the pressure gauge are faulty. If there is a fault, the entire pressure gauge needs to be replaced, or find a professional to repair it.
