Makita Hammer Drill HM0870CQ 2014: My Demolition Hammer would turn on but won't hammer

Sat, 20 Mar 2021 21:30:52 -0700

Hi,

My Makita demolition hammer will turn on and the motor will run, but no hammering. I have changed the brushes and it’s still the same outcome. I was thinking of buying a new one, but I thought I’d try my hand at repairing it. I hope you guys can help me out thanks.

Hello All,

Trying to identify this hammer for my Father.

Thanks,

P.S. Before you ask :), Yes I googled, I ebay'd. No joy. Looks a lot like a Mikita though.

Bosch Jack Hammer 11321EVS 2012: Seems to not be getting power

Mon, 01 May 2023 13:29:25 -0700

Green light on side of hammer goes on and off when I wiggle the cord. Cord has no visible damage and each wire in the cord has continuity. The wire connection block for the ground (green wire) seems to wiggle. The brushes on the motor appear to be only 1/2 worn.
