The installation position of parking lock is generally installed at 1/3 of the middle entrance of parking space, and the installation conditions are required to be on the cement flat ground. If the parking space in the residential area is a brick or colored brick floor, the thickness of the brick is required to be more than 5 cm. If the requirements are not met, cement prefabrication can be carried out in advance to install the floor, and the prefabricated area should be determined according to the overall dimensions of the parking lock.Installation tools: power belt with dozens of meters, electric drill (bit 12 or 14), hammer, nut sleeve, tape measure, expansion screw (m10*10 or m10*8), etc. Installation method: 1. Measure the placement position with a tape measure, and then straighten it. 2. Connect the power supply. First, align the screw hole with an electric drill, and then punch holes with the lock alignment mark. The electric drill should be straightened, and the depth should be about the same as the screw length. 3. Re-align the lock, align the screws and insert them with a hammer, and then tighten them with a nut sleeve.
