Repair And Fix it

Pneumatic tools offer reliability and strength. An air gun uses very few moving parts. Air pressure moves pistons that generate the power. The only maintenance needed on an air gun, or pneumatic tool, is daily oiling if the tool is not self-oiling. The main goal of an air gun is to deliver a powerful tool capable of intense amounts of torque or pressure. The most common high-impact air tools are air hammers, air drills and impact wrenches.

Air Hammers

An air hammer is not an elegant tool. It is used to repeatedly deliver blows to an object. The hammer comes with a variety of tips to shape or smooth metals. An internal piston is actuated by the air pressure from an air compressor. The piston repeatedly shoots forward and back. The different tips determine what the movement accomplishes. A flat-head hammer tip allows a worker to create a curve in a piece of sheet metal. The flat-head condenses and spreads out the metal as the piston hammers the ball into the surface of the metal. Chisel tips can be used to chip away at brick or stone, or to gouge metal.

Air Drills

Air drills use air pressure to generate high levels of rotation comparable to battery-operated drills. The tool is weaker than the electrical variation but is less likely to break down due to the limited number of moving parts. The tool delivers steady rotation regardless of the material. Electric drill motors can snag up in tough materials. Air drills are available in a standard gun style, similar to electric, and hand-held variations similar to electric screwdrivers. The tool has a quick-release connection on some models, or the standard chuck-key connection that requires a specific tool to unlock the bit.

Impact Wrenches

Impact wrenches are the most common type of high-impact air guns. An impact wrench combines the elements of an air hammer with an air drill. Rather than just spinning a gear, the tool delivers air pressure to an internal hammer that builds up briefly before spinning the gear. The rapid discharge of stored pressure or energy translates to high-torque rotation. Impact wrenches work best on stubborn or damaged bolts. The manual equivalent to this tool would be to place a wrench on a bolt and hammer at it with a sledge hammer. The tool, like all air guns, is reliable with minimal moving parts. The only maintenance necessary is to oil the tool daily. The oil prevents the internal pistons and gears from becoming sticky or dry.

Removing rusted bolts can be a frustrating and time-consuming task. Sometimes, no matter how much penetrating oil you use, you just dont have the leverage to remove the bolt. For those really stubborn bolts, an impact wrench can make all the difference. An impact wrench turns the high pressure air from your compressor into high torque for removing the most stubborn bolts. With the proper hose and fittings, connecting an impact wrench is quick and easy.

Instructions

1

Connect one end of a properly-rated air hose to the compressor by pulling back the release collar on the barrel connector attached to the end of the hose, sliding the connector over the air-outlet nipple on the compressor and releasing the collar.

2

Connect the other end of the hose to the impact wrench by pulling back the release collar on the barrel connector attached to the end of the hose, sliding the connector over the air inlet nipple on the wrench and releasing the collar.

3

Turn on the compressor and adjust the air pressure setting to the appropriate level for the tool that is connected to the compressor. Open the cutoff valve (if any) on the air outlet of the compressor.

4

Pull the trigger on the wrench briefly to check for proper operation.
