Question: Makita Impact Driver

rgailey

I used my impact driver to replace some windows and the window frame compressed the collette and it blew the spring out along with everything else now I have to use duct tape to hold the bit in so I can use my impact driver. I need to know what parts and how to change out.

Question: Impact Drill

I have an impact drill and it just slips when your tightening a bolt. What would cause that? I have replaced the hammer & anvil. What should I do next?

Question: Makita Impact BTD140

Toolfreak181

I have had this impact for about three years. I use this impact everyday but just recently I started to have problems with it. When ever I let go of the trigger it takes a few seconds for the impact to come to a complete stop. Does anybody know whats the name of the part that makes the impact come to a sudden stop when you let go of the trigger?

Hey toolfreak181
I believe this one is actually an electrical break and not a mechanical one..however parts do wear out and may have less drag on them..the first thing i would check is the brush's for wear and then the switch.. [the switch is actually the brain of the tool ..so to speak..and when you let off the trigger it puts the tool in reverse [electrically] thus the abrupt stop..
hope this helps...?!:)

The brushes are worn out. The drill has lost its power. And that really does help i didn't no that the brain of the drill was the trigger. Thanks
I and my crew have used these drivers a lot and they are great. When they start losing umph, change the brushes

Review: Makita - BTD140
5 star

its an all around drill. Very powerful and lasts a long time. The only down fall is the drill bits.
