(1) Before operation, it is necessary to check whether the power supply is consistent with the conventional rated 220V voltage on the power tool, so as to avoid wrong connection to 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 has loose screws.
(3) The impact drill must be loaded with an alloy steel impact drill or a general drill bit within the allowable range of φ6-25MM according to the material requirements. Do not use drills that are out of range.
(4) The wire of the impact drill should be well protected. It is strictly forbidden to drag it all over the ground to prevent it from being rolled or cut, and it is not allowed to drag the wire into the oily water to prevent the oily 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. When the impact drill is found to have leakage, abnormal vibration, high heat or abnormal noise during use, stop working immediately and find an electrician to check it in time. repair.
(6) When replacing the drill bit with the impact drill, use a special wrench and the drill bit to lock the key to prevent the use of non-special tools to hit the impact drill.
(7) When using the electric impact drill, remember not to use too much force or to operate skewed. Be sure to tighten the appropriate drill bit and adjust the depth gauge of the electric impact drill beforehand. When operating vertically and balancing, it is necessary to apply force slowly and evenly, and do not force the use of an oversized drill bit.
(8) Proficient in mastering and operating the functions of forward and reverse direction control mechanism, tightening screws and punching and tapping
