Electric hammer how to use electric hammer precautions, are you still using hard push?

Electric hammer is a type of electric drill, mainly used in concrete. Floor slabs. Drilled holes in brick walls and stone. Is today's more common operation of electric hardware tools, the use of also need to be careful, because abnormal use will be dangerous, so what is the correct use of common sense of electric hammer? What are the precautions for the use of electric hammer?

Electric hammer proper use of common sense:
First, "drilling with impact" operation
(1) Pull the working mode knob to the position of the impact turning hole.
(2) Place the drill bit in the position to be drilled, and then pull the switch trigger. The drill only needs to be slightly pushed, so that the chips can be discharged freely, without hard pushing.

Second, "chiseling, crushing" operation
(1) Pull the working mode knob to the "single hammer" position.
(2) The use of the rig's own weight for operation, do not need to push

Three, "drilling" operation
(1) Pull the working mode knob to the "drilling" (no hammering) position.
(2) Place the drill bit in the position to be drilled, and then pull the switch trigger. Just give it a nudge.

Fourth, check the use of dull or curved drill bits, will make the motor overload surface working conditions abnormal, and reduce the efficiency of the operation, therefore, if such a situation is found, should immediately deal with the replacement.

Five, the electric hammer body fastening screw inspection due to the impact of the electric hammer operation, easy to make the electric hammer body installation screw loose, should often check its fastening, if the screw is found loose, should immediately re-tighten, otherwise it will lead to the electric hammer failure.

The carbon brush on the motor is a consumable, and once its wear exceeds the limit, the motor will fail, therefore, the worn carbon brush should be replaced immediately, in addition, the carbon brush must always be kept clean.

Protection grounding wire inspection Protection grounding wire is an important measure to protect personal safety, so Class I appliances (metal shell) should often check that its shell should be well grounded.

The dust cover is designed to prevent dust from dipping into the internal mechanism. If the dust cover is worn out inside, it should be replaced immediately.

Electric hammer use precautions:
1. Confirm whether the power supply connected to the site is consistent with the nameplate of the electric hammer. Whether the leakage protector is connected.
2, the drill and the gripper should be adapted and properly installed.
3, drilling walls, ceilings, floors, should first confirm whether there are buried cables or pipelines.
4, when working at a height, pay full attention to the safety of the following objects and pedestrians, and set warning signs if necessary.
5. Confirm whether the switch on the electric hammer is cut off. If the power switch is on, the power tool will turn unexpectedly when the plug is inserted into the power socket, which may lead to the risk of personal injury.
6, if the workplace is far from the power supply, need to extend the cable, should use sufficient capacity, install qualified extension cable. If the extension cable passes through the pedestrian walkway, it should be elevated or take measures to prevent the cable from being damaged by rolling.

Personal protection when using an electric hammer
1, the operator should wear protective glasses to protect the eyes, when the face up to work, to wear a protective mask.
2. Keep earplugs well during long-term operation to reduce the impact of noise.
3. After long-term operation, the drill is in a hot state, and attention should be paid to burning the skin when replacing it.
4, the operation should use the side handle, both hands to prevent the reaction force when turning sprain the arm.
5, standing on the ladder or high work should do a good job of falling measures, ladder should be supported by ground personnel.
