Pneuma'c Tools

Tool Maintenance

•  Air tools are pre3y simple, right? Plug in an air

hose to an air source on one end, turn that

source on and hook your air tool up to the other

end of the hose. Or is it that simple?

•  You will have to do some research and view this

Powerpoint to get the answer to that ques'on.

Air Tool Oil

•  Most people know that cars need an oil change every 3,000 miles. I'd also say that most people don't change their oil quite that oKen. But most of us understand that the pistons generate a lot of fric'on inside of a car motor, and the rings wear out faster without proper lubrica'on. So what's that have to do with air tools? A lot.


Air Tool Oil

•  Inside of an air tool, there are pistons and rings as well.

The rings aren't metal like they are in a car motor -‐

instead they're rubber o-‐rings. But the piston itself s'll

needs some lubrica'on. It is essen'al that the metal to

metal surfaces get something slippery between them so

that they don't generate excessive heat and fric'on,

which would cause premature wear.


Air Tool Oil

•  Oiling an air tool is pre3y simple. Before you use it, just add a couple of drops of air tool oil to the tool through the air fiSng. For tools that get used once every now and then, just once before using it for the day is good enough. If it is a tool geSng heavy use, it would be a good idea to add a few drops a few 'mes through the day.


Addi'onal air tool components

•  There is a bit more to maintaining an air tool,

such as o-‐rings, cleaning, driver blades and jam

clearing. But the basics above are the only ones

that really apply equally to every air tool. If

you've got ques'ons on a specific tool refer to

the owners manual or a Squad Driver.

COMMON TECHNICAL INFORMATION

•  Opera'on

–  The tools are operated by ac'va'ng a trigger valve

located in the pistol grip handle. This valve releases

the air supply, driving the piston rod forward to impact

against the tool bit.

–  The piston rod return stroke is made by the return spring

assembly.

–  The tool bits are held by a hand operated, spring loaded, and

quick release safety retainer.


COMMON TECHNICAL INFORMATION

•  Tool Bits

– The tool bits used are manufactured from tool steel

and then hardened for maximum durability.

– These tools can be used throughout the full pressure

range of the impact tool and are available in a variety

of styles for all applica'ons.
