1. Acknowledge whether the power supply connected to the site matches the nameplate of the electric hammer, and whether a leakage protector is connected.
2. The drill bit and the holder should be adapted and properly installed.
3. When drilling walls, ceilings, and floors, you should first admit whether there are buried cables or pipes.
4. When working in high places, pay attention to the safety of objects and pedestrians below, and set up warning symbols.
5. Acknowledge whether the switch on the electric hammer drill is off. If the power switch is on, the power tool will roll unexpectedly when the plug is pierced into the power socket, which may cause personnel risks.
6. If the workplace is located far away from the power source and the cable needs to be extended, the capacity should be used and qualified extension cables should be installed. If the extension cable passes through the pedestrian walkway, it should be elevated or the cable should be damaged by crushing.
When using a hammer drill, the operator is required to strictly follow the hammer drill's operating rules to operate, and at the same time, he must pay attention to some operating precautions, so that the operation can be accurate.
