Question: No More Hammer

Alex

Hi, I got a dh50sb, that is hammering for a few minutes then nothing. I already changed piston o-ring kit and no amelioration. Can you help me with that? Thanks

Reply: No More Hammer

tom

I have owned this drill for many years. It sounds like to much grease has made its way past your striker piston. disassemble and remove all the grease and it should work, but do not flip striker piston. good luck. deep cold will stop hammer too. tom canada
