The impact hand drill is mainly based on rotary cutting, and has an electric tool with an impact mechanism that relies on the thrust of the operator to produce impact. It is suitable for drilling masonry, concrete and other materials. The following questions should be paid attention to in the accurate use and protection of impact hand drills.
(1) Before operation, check whether the power supply is consistent with the customary additional 220V voltage on electric tools to reduce the wrong connection to the 380V power supply.
(2) Before using the impact drill, please carefully check the body protection, auxiliary handle and ruler, and whether the machine has any loose screws.
(3) The percussion electric drill is installed according to the data request into alloy steel percussion drill bits or general-purpose drill bits of the permitted size between φ6-25MM. It is forbidden to use drill bits that exceed the scale.
(4) The wire of the impact drill should be well protected. It is forbidden to drag the wires all over the floor to reduce the damage and cut, and reduce the dragging of the wires into the oil and water, which will corrode the wires.
