How do I change the drill bit on the MP-UB OC?

What battery is compatible with this rotary hammer?

The MP-UB OC uses Hilti 36V Li-ion batteries (B 36 series). Ensure the battery is fully charged before use and matches the tool's voltage.

Can I use the tool for chiseling?

How do I adjust the depth stop?

Loosen the depth stop knob, slide the depth rod to the desired drilling depth, and retighten the knob. The depth stop ensures consistent hole depth.
