How to Use a Jack Hammer

Jack hammers are the perfect tools for breaking up hard materials or digging in tough ground. Using a jack hammer doesn't require any specific training, although it does take a lot of practice to use it well.

Things You'll Need

• Protective gear (work boots, leather gloves, protective goggles, earmuffs)
• Jack hammer

Instructions

1. Don all protective gear before beginning work. The earmuffs are necessary to muffle the sound and protect your eardrums.

2. Plug in the jack hammer.

3. Position the jack hammer over the surface to be broken. Make sure to place it at a slight angle to the ground.

4. Press the "On" switch while holding the jack hammer steady.

5. Use a prying motion to force the concrete (or other material) upwards while the jack hammer is cutting into it.

6. After the jack hammer loosens each large chunk of material, use the jack hammer to break the chunk into smaller pieces. Then clear the pieces away. This will leave you with a cleaner area to work with. It will also give the jack hammer and your arms some time to rest. (Sustained vibration from the jack hammer can lead to Raynaud's Disease, so this rest time is important.)

7. Turn off the jack hammer and unplug it when you finish.

Tips & Warnings

• Use a small jack hammer for smaller jobs, and a bigger jack hammer for larger jobs.

• Jack hammers can be extremely dangerous. Make sure that your work area is clear before starting.

• Do not take your attention away from the jack hammer while it is on. Constant attention is important with heavy tools like a jack hammer.
