This is more then likely caused by the plastic gears inside the drill wearing down. Makita may replace/repair under warranty depending on when you purchased the drill.

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 impact driver wobble


Many of my customers that use this tool heavily have the same problem. It's usually the Hammer Case (PN 154590-6). The nose if the case is the bushing that holds the anvil in place and sometimes wears out of round. Rarely the anvil (PN 324432-0) wears where it passes through the hammer case so check that also.

The screw point got stuck inside of the makita


Low quality steel drill bits get stuck in the Makita because the hammer impact squashes the metal, forming a ridge that gets snagged on the anvil's steel ball bearing. Use only impact drill bits.

My Makita BTD140 seems to be gradually losing torque. Batteries(tried 4) check out okay. It just doesn't have the power to drive screws like it used to.


If the motor is working good then check the hammer and anvil to see if they are rounded over. A weak spring under the hammer can also add to this problem. Also check the spindle and the two steel balls that hold the hammer to the spindle. Sometimes the spindle will become chipped on the edge of the grooves and let the steel balls get out of alignment in relation to the hammer.
If the motor itself is loosing power with full batteries then you will need to check the brushes and the armature for damage. If the brushes are chipped or broken you should replace both the brushes and armature. Any questions please post back.

How to pull apart makita 6980 impact wrench


the battery is removed. remove all screws around the outside of the drill/driver. the side comes off. the motor is a johnson motor connected to the planetary drive and hammer/anvil assembly. the motor drive extends inside the anvil via one gear off the motor. the hammer and anvil come out as one piece. if you depress the center of theanvil with an arbor press, two ball bearings come out and the escapment comes out with the spring. now you can clean the inside of the hammer and gears of the hammer drive.
