Unfortunately, the quality of the hammer is not the best. The recording was very sluggish at the beginning. After about 2-3 hours of work, the recording was so "knocked out" that the chisel pretty shaky. I do not know what happens if you still runs the Hammer longer. Whether it is the recording are all the way? What bothered me most, however, is that the chisel can be locked in one position, in other words there is no possibility of rotation for flat chisel. This is particularly inconvenient especially in tight places, because then the front handle must be turned back.
The demolition hammer came out with me from Spain and the oil bottle has not survive. The whole suitcase inside and half board were oil saturated. Were included 3 or 4 pairs of replacement coal for the engine. I do not know if I should interpret this as a good or bad sign.
In summary:
Very high breaking performance ++
2 Massive chisel Set +
4 pairs of replacement coals +
Device is quite heavy 0 (is probably the good performance owed)
According unit is 0 (should only be used with ear protection and safety goggles)
No chisel adjustment -
Worn recording -
Oil leaked by transport -
Metal box with Styrofoam bit of a joke -
I have returned to the chipping hammer and have me for the rest of the work is a professional device borrowed from the hardware store (30 a day). From the performance the professional device was not felt strongly but handling and some details were clearly better implemented.
