• Heavy duty breaker, Cobra mk1. Also powered by
a two-stroke engine, the Cobra mk1 has a separate im-
pact mechanism activated by pressing the machine
down. Thus, the engine can be run without engaging the
impact mechanism. As powerful as a 27 kg (60 lbs) pneu-
matic breaker, the Cobra mk1 is suitable for very de-
manding breaking and driving jobs.
