What to know about the Tool

Operating Principle

Air Spring

An air spring tool operates much like a conventional pneumatic tool. It drives the nail using a charge of compressed air pushing against a piston/driver assembly. The piston acts on the nail resulting in a nail being driven into a variety of substrates.

The difference in the air spring tool is that the high pressure air is permanently housed inside a factory charged chamber. This quantity of air is further compressed by an electric motor acting on the piston/driver assembly. When the user initiates driving a fastener, a mechanism that is part of the motor releases the piston driver much like a conventional pneumatic tool. This pressurizes the chamber above the piston/driver acting upon the fastener. 

Immediately upon the nail being driven, the energized electric motor begins to lift the piston/driver to place it in a ready to drive position for the next drive. In most designs, the time to drive is many times faster than the time required to lift the piston/driver. This time required to lift is the primary difference between a conventional pneumatic and an air spring tool.

The internal mechanism is a sophisticated component and requires some additional care over the life cycle of the tool.

Refer to your owner’s manual for instructions for use, troubleshooting guides and specifications.

Guidelines and Hazards of Use

Before performing any service on tools, always refer to the manufacturers’ recommendations. Note that some tools are pre-loaded (either with air pressure or a compressed spring).  In most cases, these tools should only be serviced by an authorized service center.
