Usage:

When calibrating your product, it is best to add some lubricating oil to the rubber parts (salad oil for cooking can also be used). The front of the switch must be upward and the position should be the same when adjusting before leaving the factory. If there is any error in matching with your product in use, there are four screws on the head to make fine adjustment. For example, if you need to adjust to the left, loosen the screws on the left first and then tighten them slowly, and move the screws on the right to the position you need. Before moving in a certain direction, one or two screws on the opposite side should be slightly loosened before adjustment.

Notes:

1.The real color of the item may be slightly different from the pictures shown on website caused by many factors such as brightness of your monitor and light brightness.

2.Please allow slight manual measurement deviation for the data.
