10December 2021

the most common pneumatic tool in an automotive 
workshop is the air impact wrench it's sometimes   called a rattle gun it's easy to hear why taking 
the wheels off the car to replace the tires is   a typical application for this air tool it often 
needs a lot of torque to twist the nuts free the   rattle gun can be set to spin in either direction 
and this valve controls how much torque it applies   it should never be used for finally tightening 
wheel nuts there's a real danger of doing them   up much too tight that could cause the bolts to 
fail and the wheel shear off the vehicle while   it's moving another rule with the air impact 
wrench is to use only these specially hardened   impact sockets extensions and joints the sockets 
are special six point types and these flats can   stand the sudden force that the rattle gun 
provides this is an air ratchet it uses the   force of compressed air to turn a ratchet drive 
it's used on smaller nuts and bolts once the nut   is loosened the air ratchet spins it off in 
a fraction of the time it would take by hand   this is an air chisel it's useful for driving 
and cutting the extra force that's generated by   the compressed air makes it more efficient than 
a hand chisel and Hammer just as there are many   chisels there are many bits that fit into 
the air chisel depending on the job at hand this is an air drill it has some important 
advantages over the more common electric power   drill with the right attachment it can drill 
holes grind polish and clean parts unlike the   electric drill it doesn't run the risk of 
producing sparks which is important around   flammable liquids or petrol tanks an air drill 
doesn't trail a live electric cable behind it   which could be cut and cause shock and burns and 
an air drill also doesn't get hot with heavy use   this is the simplest air tool it's a blow gun 
or air duster it's really just compressed air   by itself controlled by a lever or valve it's 
used to blast debris and dirt out of confined   spaces that can be dangerous so I protection 
must be worn whenever it's used noise levels   are usually high so ear protection should also 
be worn it's also dangerous to use it to clean   yourself down it's blast should always be directed 
away from the user and anyone else working nearby
