1. Confirm whether the power supply connected to the site is consistent with the nameplate of the electric hammer. Whether there is a leakage protector connected.
2. The drill bit and the holder should be adapted and properly installed.
3. When drilling walls, ceilings and floors, first confirm whether there are cables or pipes buried.
4. When working at heights, pay full attention to the safety of the objects and pedestrians below, and set up warning signs if necessary.
5. Confirm whether the switch on the electric hammer is turned off. If the power switch is turned on, the power tool will turn unexpectedly immediately when the plug is inserted into the power socket, which may lead to the danger of personal injury.
6. If the workplace is far away from the power supply, when the cable needs to be extended, use a cable with sufficient capacity and install a qualified extension cable. If the extension cable passes through the sidewalk, it should be elevated or measures should be taken to prevent the cable from being crushed and damaged.
