(1) Before operation, be sure to check whether the power supply is consistent with the 220V rated voltage agreed on the power tool, so as to avoid mistakenly connecting the 380V power supply.
(2) Before using the impact drill, please carefully check the insulation protection of the body, the adjustment of the auxiliary handle and the depth gauge, etc., and whether the machine screws are loose.
(3) The impact drill must be loaded into the alloy steel impact drill bit or the ordinary drilling bit within the allowable range of φ6-25MM according to the material requirements. The use of out-of-range drills is strictly prohibited.
(4) The impact drill wire should be well protected. It is strictly forbidden to drag it to the ground to prevent being crushed and cut, and it is not allowed to drag the wire into the oily water to prevent the oil and water from corroding the wire.
(5) The power socket of the impact drill must be equipped with a leakage switch device, and check whether the power cord is damaged. If it is found that the impact drill has leakage, abnormal vibration, heat or abnormal noise during use, it should stop working immediately and find an electrician for inspection and maintenance in time.
(6) When replacing the drill bit, use a special wrench and drill key to prevent non-special tools from impacting the drill.
(7) When using the impact drill, remember not to use too much force or to operate it skewed. Be sure to properly tighten the drill bit in advance and adjust the depth gauge of the hammer drill. The vertical and balancing action should be done slowly and evenly. How to change the drill bit when impacting the electric drill with force, do not use too much force on the drill bit.
(8) Proficiently master and operate the forward and reverse direction control mechanism, screw tightening and punching and tapping functions.
