The DM 406H weighs only 16kgs making this heavyweight performing motor surprisingly easy to handle and transport. It requires a 40 litre/min @ 140 bar to operate, for which Husqvarna manufacture two suitable power packs, the PP325E which is 415V electric and ideal for internal use or use in confined, poorly ventilated areas, or the PP518 variable flow rate petrol power pack (with a variable flow rate of 20, 30 and 40 l/min).
The hydraulic gearbox is easy to manoeuvre and enables the operator to easily and conveniently change the output shaft rotational speed during use, which provides a smoother start and straighter holes.
