Before starting operation, check that all screws are tightened. 2. Be sure to hold it during operation to avoid accidents. 3. When drilling, the distance on both sides should be equal. If they are not equal, the force will be uneven. 4. To adjust the required size, be sure to tighten the screws with a hexagon wrench. 5. When replacing the drill, the power must be turned off. 6. Do not use on steel plates or other metals. 7. The drilling speed must be slow, and the drilling material must not contain iron, nails or other metals. 8. Can not drill holes backwards on the ceiling, only vertical holes from top to bottom. 9. The cuttings generated during the drilling process should be cleaned with special tools instead of being cleaned by hand.
