Operating rules

(1) work must concentrate on, not only to keep the head clear, more rational operation of electric tools tired, prohibited after drinking or taking stimulants, drugs after the operation of the machine.

(2) the shock case must be protected by earthing wire or neutral wire.

(3) the electric drill wire should be in good condition, and it is strictly forbidden to drag and prevent the rolling and cutting. The electric wire is not allowed to be dragged into the oil water to prevent the oil and water corrosion wire.

(4) check whether the insulation is in good condition and whether the switch is sensitive and reliable.

(5) the clamping bit is suitable for proper use. It should be idling for several minutes before use.

(6) when drilling, the bit should be slowly contacted with the workpiece, not to force too much, to break the drill bit, to burn the motor.

(7) pay attention to standing posture at work, should not be taken lightly.

(8) make sure that the machine is stable and always balanced.

(9) use electric drill in dry place, no gloves, prevent bit from twisting. When using electric drills in humid places, stand on rubber pads or dry wooden boards to prevent electric shock.

(10) if electric drill leakage, vibration and high temperature overheat are found in use, it should be stopped immediately before cooling.

(11) when the electric drill does not stop rotating, it can not unload or change the drill bit. When the abnormality occurs, no other person can disassemble or assemble it, and should be repaired by a special person in time.

(12) the power supply should be cut off immediately when power failure, rest or leave the work place.

Service and maintenance

The impact electric drill is designed for double insulation. It is reliable to operate. It is not necessary to use protective earthing (zero connection) when using. The single phase double pole plug can be used, and the insulation gloves and insulating shoes can be worn without using the insulating diode. In order to make the operation convenient, flexible and powerful, the impact drill usually has an auxiliary handle. Due to the double insulation of the impact drill and no grounding (zero) protection, special attention should be paid to the protection of the rubber cable. When carrying mobile electric drill, the handle of electric drill must be grasped, and the rubber cable can not be pulled when moving. Rubber sheathed cable can not make wheel rolling and foot treading; prevent mouse bite.
