2. ###DANGER### • SHOP AIR PRESSURE IS AROUND 100 TO 150 POUNDS PER SQUARE INCH! • THIS IS ENOUGH PRESSURE TO SEVERELY INJURE OR EVEN KILL! • YOU MUST UNDERSTAND AND RESPECT THE FACT THAT AIR CAN INJURE OR KILL!

3. THE AIR COMPRESSOR • The air compressor is the source of compressed air for the shop. • It normally has an electric motor that spins an air pump. • The air pump forces air into a large metal storage tank. • Metal air lines feed out from the tank to several locations in the shop. • The Technician can then connect a flexible air line to the metal line. • The compressor turns on and off to maintain a constant air pressure.

4. What can air under pressure do? • A) blow off asbestos from brake shoes. • B) injure or kill you. • C) cool you off on a hot day • D) nothing it is perfectly safe.

5. AIR HOSES • These high pressure flexible hoses are connected to the metal lines from the air compressor. • They allow the Technician to take the air pressure to the vehicle being repaired. • Quick disconnect couplings are used to allow the technician to connect and disconnect at any point in the shop.

6. What do flexible air hoses allow the technician to do • A) work any where in the shop. • B) work more efficiently • C) take air pressure outside the shop • D) connect to any point in the shop • E) all of the above

7. AIR TOOLS • Also called pneumatic tools. • Use air pressure for operation. • They are labor saving tools well worth their cost. • They must be cared for and maintained or they WILL FAIL! • ALWAYS LUBRICATE THE AIR TOOL BEFORE USE. • Squirt a few drops of air tool oil into the air inlet, this protects the internal parts and increases tool life.

8. What should you do before you use an air tool? • A) clean it with soap and water. • B) take it out of its box. • C) lubricate it with air tool oil • D) just use it

9. Air Wrenches • Often called impact wrenches. • Provide a very fast way of removing threaded fasteners. • A button or switch provides a way to reverse direction of the tool. • Impact wrenches come in various drive sizes. • Starting with 3/8, 1/2 and ¾ drive.

10. CAUTION! • UNTIL YOU BECOME FAMILIAR WITH THE OPERATION OF AN AIR WRENCH, BE CARFULL NOT TO TIGHTEN NUTS AND BOLTS OR LEAVE THEM TOO LOOSE. • IT IS EASY TO STRIP OR BREAK FASTENERS WITH AIR TOOLS.

11. It is easy to do what with an air tool • A) break a part • B) strip a part • C) leave a part too loose • D) leave a part to tight • E) all of the above

12. AIR RATCHET • An air ratchet is a special type of air wrench designed to work in confined spaces. • It will fit in between the radiator and the water pump so the pump can be removed. • Air ratchets are normally 3/8 drive but can also be 1/4 drive for lite work.

13. AIR HAMMER • Often called a “zip gun” or chisel. • Is used to cut or hammer a stuck part off or out. • They can produce between 1000 and 4000 impacts per minute. • Several different attachments for cutting and hammering are available.

14. What is another name for an air wrench? • A) air gun • B) impact wrench • C) zip gun • D) whizzer

15. CAUTION! • NEVER TURN AN AIR HAMMER ON UNLESS IT IS PRESSED TIGHTLY AGAINST THE WORK PIECE! • IF IT IS NOT AGAINST THE PIECE, THE TOOL HEAD COULD FLY OUT FROM THE HAMMER WITH GREAT FORCE! • JUST AS IF IT WERE SHOT FROM A GUN!

16. BLOW GUN • An air powered blow gun is used to clean parts washed in solvent. • It is NOT used to blow off dirt or dust from parts before disassembly. • Many parts contain asbestos when it becomes airborne can cause cancer.

23. DRILL PRESS • A drill press is a stand up drill used for drilling work that can be taken to it. • It has an adjustable table. • It can accept large drill bits.

24. Drill press Safety rules • Secure the part to be drilled with a vise or C- clamps. • Always use a center punch to indent the hole and start the hole. • Remove the chuck key before starting the drill! • To prevent possible injury release drilling pressure just before the bit breaks through the bottom of the part (Drill bits tend to catch when breaking through).

25. TIRE CHANGERS • Two different types of changers on the market today the rim clamp and the center clamp. • We have both. • One is used for steel wheels and one is used for everything else.

26. BUMPER LIFTS • NOT • USED • ANYMORE • BECAUSE MODERN AUTOMOBILES HAVE • AIR BAGS!

27. Why are bumper lifts not used anymore? • A) because they are to heavy. • B) because they cost to much • C) modern automobiles have air bags. • D) what’s an air bag

28. FLOOR JACKS • The floor jack is used to raise either the front, sides or the rear of a vehicle. • To avoid damage to the vehicle the floor jack must be placed under a solid part of the vehicle. • It is very easy to crush a oil pan or a gas tank.

29. Remember floor jacks have wheels • This means that the vehicle being jacked up must be free to move. • NEVER WORK ON A VEHICLE WITH JUST THE FLOOR JACK SUPPORTING IT! • The smallest vehicle weighs 2000lbs this is enough weight to ruin your day and make a mess of my shop floor!

30. Where is a floor jack placed to raise a vehicle • A) anywhere that will hold the weight • B) under the oil pan • C) on a solid part of the vehicle such as the frame • D) on the side
