Power tool operating procedures
1. Personal protection when using an electric drill
1.1 Wear a protective mask when working with your face up. Wear safety goggles for eye protection when drilling holes in cast iron castings.
1.2 The drill holder should be properly installed.
1.3 When the drill bit is in a hot state during operation, care should be taken to burn the skin.
1.4 When drilling a hand-held electric drill with a diameter of Φ12mm or more, a pistol drill with a side handle should be used.
1.5 When working on a ladder or working at a height, measures for falling from a height should be taken, and the ladder should be supported by ground personnel.
2. Matters needing attention before operation
2.1 Confirm whether the power connected to the site is consistent with the nameplate of the electric drill. Whether there is a leakage protector connected.
2.2 The drill bit and the holder should be adapted and properly installed.
2.3 Confirm that the switch on the electric drill is in the locked state, otherwise the electric drill will turn unexpectedly and immediately when the plug is inserted into the power socket, which may lead to the danger of personal injury.
2.4 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.
