How to Use a Pneumatic Air Hammer: Tips and Techniques

How to Use a Pneumatic Air Hammer

An air hammer or pneumatic hammer is a very powerful & convenient tool that operates to chisel, carve, or disrupt what any of you need in mechanical processes for example stone, concrete, and many other hard materials.

Using an air hammer is a learned skill, but with good safety habits, you will be safe while operating the tool as well as more effective, regardless of your experience.

Why Use An Air Hammer?

Air hammers offer a series of advantages compared to manual chisels and hammers such as;

High striking power – Air hammers strike 2000-5000 blows per minute which enables you to break through hard stuff quickly.

Less wear on you — Pneumatic power saves your arms and hands by doing the work of straining.

Accuracy — Use of replaceable chisel bits for carving precise shapes and designs

Chameleon Capable – exchange out chisel tips to carve away stone, concrete, metal, tiles and so on

For heavy-duty stone carving, concrete removal, or similar tasks, an air hammer can save time and energy compared to manual techniques.

Key Components of an Air Hammer

Air hammers have several main parts to understand:

• Air compressor – Provides compressed air to power the hammer.
• Cylinder – Houses the piston that drives the hammering motion.
• Chisel bit – The interchangeable tip that makes contact with your workpiece.
• Throttle – Controls airflow and hammering speed.
• Retainer spring – Holds chisel bits in place.

Familiarize yourself with each component before operating your new air hammer.

How to Use an Air Hammer Step-By-Step

Follow these steps when using your pneumatic air hammer:

1. Select the Right Chisel Bit

Choose a chisel bit suited for your material – pointed tips for stone, flat for concrete, etc. Insert it into the cylinder and secure it with the retainer spring.

2. Adjust the Throttle

Start at a low setting until you get a feel for the power. Increase the throttle to boost striking speed.

3. Maintain Proper Stance

Keep both feet firmly on the ground and grip with two hands to control the hammer.

4. Let the Hammer Do the Work

Allow its pneumatic power to strike and chip away material without forcing pressure.

5. Work at an Angle

Position the bit at a 45° angle to the workpiece to maximize efficiency.

6. Clear Debris

Regularly stop to brush away dust and debris for better precision.

7. Check for Wear

Inspect bits and replace any that become cracked, chipped, or blunt.

Safety Precautions When Using an Air Hammer

Air hammers require caution to operate safely:

• Use eye protection (safety glasses and face shield).
• Wear heavy work gloves to reduce vibration.
• Use earplugs or protective earmuffs to lessen noise.
• Inspect hoses for damage before use.

• Ensure adequate airflow and pressure from the compressor.
• Disconnect the air supply when changing bits or servicing.
• Maintain a balanced stance and firm grip at all times.
• Keep others away from your workspace when operating.

Prioritizing safety will allow you to fully leverage the power and efficiency of your air hammer.

Air Hammer Maintenance Tips

To keep your pneumatic hammer performing well:

• Add 2-3 drops of pneumatic tool oil before each use.
• Clean bits thoroughly after each use.
• Check for worn bits and damaged internal parts.
• Store properly in a clean, dry space.
• Follow manufacturer maintenance recommendations.

With regular care and servicing, an air hammer can deliver years of reliable service.

Frequently Asked Questions

How much PSI should I use with an air hammer?

Fully effective air hammers generally need 70-90 PSI at 4-6 CFM from the air compressor. Always refer to your specific model and what it recommends.

How do I know when to replace a chisel bit?

Replace bits that are cracked, chipped, bent, or excessively blunt. Proper bits make tasks easier and safer.

What materials can an air hammer be used on?

Air hammers work on stone, concrete, brick, tile, metal, and other hard materials. Use the right bit for your specific application.

Is it normal for the hammer to vibrate a lot?

Some vibration is expected, but excessive shaking can indicate an issue. Make sure bits are secured properly and the tool is well-oiled.

How can I reduce noise levels?

Using ear protection, maintaining bits, and oiling properly will all help reduce noise. You can also try lowering the throttle speed.

Summary

• Pneumatic air hammers provide increased striking force and reduced fatigue for stonework
• Always select the right chisel bit and start at lower throttle settings
• Maintain proper stance, grip, and angle when operating the tool
• Follow key safety precautions like eye and hand protection
• Perform regular maintenance and bit changes for optimal performance

Now the information is in your hands, you have the know-how to use an air hammer efficiently and safely for your project. Practice and wear your safety gear Happy hammering!
