Ответ на "How do I disengage the auto chuck release."Hi Jason, I am Michael, it’s true with this machine, the best from all over the World what Dewalt created ever and believe me, I try many like Milwaukee, Hilti, Wurth, Makita and others but none like this best DW920 and without need spare parts or repair in 20 years of full use in Electrotechnical, Mechanical and Electronics areas. The versatility impressive, time of use of Battery so long, and even use like power mechanical tool with adapters of tubular wrench of 17, 19 mm for faster work. amazing tool. I need a Motor because I am afraid in sun to not let me down even do not notice weakness yet. Michael.
