What should you know about jackhammers & air compressors?

Some major points of consideration are safe job site setup, proper personal protection equipment (PPE), and understanding the tool itself. As a side note, before the advent of air compressors and pneumatic jackhammers, construction work took on a whole different nature.

How do pneumatic jackhammers work?

Pneumatic jackhammers work with air compressors that force air into the housing of the tool. The compressed air activates a trigger valve that rapidly opens and closes. The valve causes an internal piston to move up and down, striking the hammer’s detachable chisel or bit.

Are electric jackhammers better than pneumatic jackhammers?

While an electric jackhammer is lighter and does not require an air compressor, it is far less effective than a pneumatic jackhammer. For most “true” construction jobs such as sidewalk or roadway demolition, the desired jackhammer is a 90-pound pneumatic jackhammer.

How to use a jack hammer?

Ensure the work area is well-ventilated and free from obstructions. Keep the jack hammer firmly in both hands and maintain a stable stance. Never use a jack hammer overhead or on slippery surfaces. 1. Preparation: Mark the area to be broken up. Clear away any debris or obstacles. Choose the appropriate bit for the job. 2. Starting the Jack Hammer:

How do you use an electric jackhammer?

When using an electric jackhammer, workers must locate the electrical cord on their shoulder to prevent accidental damages to the cord that can cause electrocution. Workers should also secure compressor hose ends to prevent whipping if an accidental cut or break happens. You should use a water spray control system to minimize airborne dust.

Can you use air hoses with a jackhammer?

If you’re using a pneumatic jackhammer, you must use air hoses of course. Because air hoses are subject to being twisted, turned, and exposed to traffic, special care must be used when connecting them to each other and to a jackhammer. Once a pressurized air hose breaks loose it can cause injury and property damage.
