Hitachi hammer drill going bad?

BlueBSH · 06-24-2011, 04:11 PM

Well I got a hammer drill to do some tap con screwing, worked great! for the first 30 screws... then I started to have speed issues... right now if I push the trigger in a tiny bit it should rotate slowly, but no, full speed! it never did this until recently... it use to be variable speed, but now it wont go anything but max... is it gone? or can I take it apart and clean it or anything? didn't really want to have to buy another one.... thanks!

Could be a bad trigger switch.......But most hammer drills that I've ever used have not been variable speed, are you sure yours was? If it was I'd take it back to the store........if it's used or past the return period I'm sure a trigger could be had for $20-$60

I had a similar issue with an older model a few years back. The issue is with the "speed control dial" on the trigger. It was two years old and Hitachi fixed it same day at no cost for me.

You can look up replacement parts if it is out of warranty here:
