Carbon brush cleaning
When your jackhammer begins to slow down or shut off, the carbon brushes may need to be replaced by the cup.
The carbon brushes can be found on either side of the jackhammer enclosed in black metal.
To check the carbon brush, remove the first two screws on both sides of the casing by using a Philips Head Screwdriver.
Then use a flat head screwdriver or coin to unscrew the inner screw. This will open up the full casing for the carbon brush.
If your carbon brush is full and square, it’s still in good condition. When your carbon brush needs replacement, it’ll be flattened and grooved noticeably.
Slide the new brush into the casing and screw back the casing as it was before.
Check both sides once a month or if the jackhammer is slowing down or not turning on.

- Don’t use a demolition jackhammer to demolish the materials directly over your head.
- When demolishing concrete walls, don’t try to break large portion at a time; otherwise the large debris may fall on your feet or leg. Try to break the small portion at a time.
