Wouldnt touch it with a 10 foot pole, ask then has it been repaired?
Dewalt tools have a 2 -3 year repair warranty not 12 months , Dewalt also have a 28 day satisfaction warranty , noticed a 15 amp motor but it is rated 1600 watts (1600/240v = 6.6amps!!) .Seems Bigger Boys are giving out no quite Bigger Bull.
Nothing with them add up so dont get near.
Remeber you can walk into any Bunnings store Australia wide and complain or sort out problems.
