Atlas Copco Cobra mk1 Operator's Handbook

18
If rotation becomes sluggish due to a crack, or the drill
keeps sticking, lift the machine a few times to improve
flushing.
If the tool gets stuck, stop the machine and free it with a
drill wrench or a spanner.
Drill dust in damp rock can cause the drill to stick. Pouring
more water into the hole dissolves the sludge and frees
the drill.
