FAQ

Q: How to operate the three-function switch?

A: Rotate the function dial to the corresponding icon: the hammer icon is a hammer drill, the drill icon is a flat drill, and the pick icon is a single pick. Please ensure that the machine is completely stopped before switching.

Q: Are round shank and square shank drill bits interchangeable?

A: Not universal. This machine uses round shank drill bits (SDS standard). If you require square shank drill bits, please select the corresponding model.

Q: Is the impact force sufficient in single-pick mode?

A: The pickaxe mode of a 900W electric hammer is suitable for lightweight concrete, brick walls, and ceramic tiles, but not for reinforced concrete or thick stone slabs. For heavy-duty breaking, please use an electric pickaxe.

Q: How to maintain the Three-Function Drill Hammer?

A: Clean the dust from the ventilation opening after each use; Regularly add lubricating grease to the clamp head; Check the length of the carbon brush and replace it when it has worn down to one-third of its original length.
