How to use

Select an appropriate masonry or concrete drill bit compatible with the rotary hammer's chuck and insert it securely. For drilling, choose the rotary or rotary-hammer mode according to the material and desired progress; start with a low speed and increase as needed. For light chiselling, switch to hammer mode and use a suitable chisel bit, applying steady, controlled pressure. Secure the workpiece or mark the drilling point, wear eye and hearing protection, and keep both hands on the tool for stable guidance. Recharge or replace the battery when its charge is low and follow manufacturer instructions for battery handling and storage.

Usage recommendations

Use the rotary hammer with bits rated for masonry and concrete; avoid applying excessive lateral force to the tool to prevent premature wear. For deep or large-diameter holes, drill progressively with smaller pilot holes. Regularly check and replace worn bits. When working in enclosed spaces, ensure adequate ventilation and use dust extraction or a vacuum to reduce dust exposure.
