What is pneumatic tools?
Pneumatic tools, drills included, convert the energy of a compressed
gas to mechanical energy. The more you compress a gas, the more it
will tend push outward on its surroundings (this is called pressure).
This pushing can be used to do work, like moving a piston for example.
A pneumatic drill works like a small engine that uses the pressure
of a compressed gas to move a piston, which turns the shaft of the
drill. |

| Safety points for using pneumatic tools |
| |
|
Compressed air is used in a growing number of
household tools. It is both powerful and hazardous. Here are a few
precautions for when you are working with pneumatic tools:
|
| |
-
If you are doing carpentry or some
other project and using a pneumatic tool that shoots fasteners
(such as nails or staples), make sure it is equipped with a
device that keeps the fastener from ejecting unless you are
pressing the muzzle against a firm surface.
-
Just as you don't point a gun at
something you don't want to shoot, never point a tool at items
you don't want to fasten.
-
Don't hold the tool with your finger on the
trigger. Move it into place when you are ready to start shooting
fasteners into something. Most pneumatic tools have very sensitive
triggers; it takes only a small amount of pressure to activate
them.
-
Be careful with the air hose. Keep in clean,
and don't crimp it or crush it. Although they appear stronger
and more durable, you should treat an air hose like you would
treat an electrical cord.
-
Don't try to drive a fastener into a hard or
brittle surface.
-
Check to see if the fastener you are using will
protrude through the wood or other material you are working
with. If so, make sure that protruding nail won't pose a hazard
for anyone who will come into contact with your work.
