Hya$sville Volunteer Fire Department Training 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. 11/22/09 Pneuma'c Tools 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. 11/22/09 Pneuma'c Tools 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. 11/22/09 Pneuma'c Tools 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. 11/22/09 Pneuma'c Tools 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. 11/22/09 Pneuma'c Tools Air Tools Carried on Rescue Squad 1 11/22/09 Pneuma'c Tools Air Shear & Wizzer Saw 11/22/09 Pneuma'c Tools Air Shear •  Air Shears, Cut squares, angles, and circles. •  Heavy-­‐duty cuSng blade makes cuts in cold rolled steel, aluminum, 'n, and plas'cs up to 20-­‐ga. thickness. •  Strokes per Minute 4200 •  Gauge Thickness 20, •  Average CFM @15 Second Run Time 4.0, CFM @Full Load 21.0 @ 90 psi 11/22/09 Pneuma'c Tools Wizzer Saw/Air Cut-­‐Off Tool •  Lock off thro3le to prevent accidental start up •  Free Speed: 22000 rpm •  Average Air Consump'on CFM: 5 @90 psi •  Applica'ons: cuSng through sheet metal, fiberglass, bolts, muffler clamps and hangers; also grinds down burrs and rough edges 11/22/09 Pneuma'c Tools ½ in.

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. 11/22/09 Pneuma'c Tools 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. 11/22/09 Pneuma'c Tools PracScal Exercise •  Demonstrate the set up and use of all pneuma'c tools listed •
