(2) Fix and tighten the product with screws. (It is recommended to use spring washer and flat gaskets)

(3) After installation, carefully check whether the hit head for blockage when pushing the hit head, and whether
the switch core works within the specified range; if found fault, check it and re-install, and then connect the lead
wire.
