My makita hr3000c won't hammer what is the most likely reason


Beware that its an old type Makita where several parts are not are deliverable any more lubrication is the first reason leaking 2 seconds and if its leaking it becomes hot inside has lost its pneumatic working so the parts are become hot and will be worn soon and the person who works with leaking tools overload themselves rather than the work object.
Makita has sometimes problems in front of the impact bolts by its rotary hammers. to observate the part cilinder 331559-9 very carefull if its not torn nowhere and this applies also to part tool holder 323912-3 it must be smooth inside in front where the impact bolt is sealed

Makita HR4041C rotary hammer drill


There is no tension to adjust on the Makita HR4041C rotary hammer drill. If you are not getting the hammer action you think you should be it's possible the o-rings on the piston are damaged or not lubricated or the striker is stuck or not lubricated enough to work properly. If you're having problems with the bit turning, there are several gears that turn the bit that could be slipping or are stripped. If you need a manual or brakedown of the tool, one is available on www.makitatools.com. The insides of rotary hammers are fairly complicated so be carefull of what goes where if you decide to take the tool apart to check for internal problems.

Makita sds max avt --when it is on the chisel only mode it still revolves like in drill mode . What has caused this ?


If the bit turns freely it's possible you have the change ring in the forward position. The HM0860C is a demolition hammer, not a rotary hammer so the bit should not be rotating under power for any reason. On the HM0860C the changing ring on the nose does slide forward to let you choose and lock the chisel bits in 12 different angles. Check to make sure the change ring is in the locked position.

So does the hr200 work as a miny jack hammer or just a driil, can i buy a diffrent bit for that type of model to jack hammer up a little concrete


This is an older, discontinued model Makita that only works as a hammer drill. It does not have the dial selector the newer models have to switch from 'drill' to 'hammer drill' to just 'hammer'. If you need, there's a parts breakdown and user manual available at:

Bits will not lock into chuck


First I would go to Makitatools.com and download a schematic for this tool. But it is pretty simple to remove the rubber dust shield and plastic collar to look for debris and proper movement in the chuck assembly. Make sure also that you are using the right SDS bits in tool. You should be able to push the bit into the collar and twist until it goes into and locks. Let me know and I will help further

Drive systems Question


SDS (or Slotted Drive System) bits for hammer drills/rotary hammers allow the bit to slide in the chuck and enhance the hammering action of the tool. For most applications, these bits provide plenty of torque. SDS Max bits are similar to SDS bits, but have larger shanks and come in larger sizes than SDS bits. These powerful bits are useful in industrial applications.
