What is this
air hammer
air ratchet
air impact wrench
air nozzle
What is this equipment called?
air compressor
air dryer
air cooler
air ratchet
What is not true about 3/8" drive air ratchets?
They may be used instead of a 1/4" drive ratchet
They are used on large nuts and bolts, such primary suspension parts and wheels
They work in a fraction of the time it would take by hand
They work well where there isn't much room to swing a ratchet handle
Pneumatic impact wrenches are usually used for what?
Large fastener removal
Small fastener removal
Body work
Electronic systems work
Why do pneumatic tools have quick-connect fittings?
so that various air tools can be used on the same air hose
so the air moves through the hose quicker
so the air moves thru the hose slower to prevent over torque
None of these answers are correct
What are pneumatic tools driven by?
Pressurized air
Electricity
Compressed gas
Pressurized hydraulic fluid
How is does a shop air compressor create air pressure for a shop pneumatic system?
Pneumatic compressors use a manual pump driven by techs in shifts
A small engine- driven pump draws in outside air, then forces it into a storage cylinder
An electric pump draws in outside air, then forces it into a storage cylinder
Air pressure is created using special heavy air from a large cylinder
This "negative pressure" powered tool is used to collet particulates and small amounts of liquids from shop floors and vehicle interiors.
Vacuum Cleaner
Grinding Tool
Electric Drill
Air chisel
Which tool should be used to torque a fastener?
Engines should be lifted with....
A floor jack.
An Engine Hoist
A Transmission Jack
2 People lifting by hand.
What type of fastener is this?
Wing Nut
Castle Nut
Hex Nut
Acorn Nut
Two-post automotive lifts (as depicted) use this to raise the lift carriage and vehicle:
pneumatic pressure from the shop air system
electrically-driven hydraulic pump
electrically-driven jackscrews
Manual pump action, similar to a jack
Pneumatic impact wrenches use these to produce the force that loosens fasteners:
reciprocating (back and forth) hammers
an assistant tech blows into an attached hose
electricity
rotating dogs (hammers)
Air ratchets are a better choice for fine, controlled fastener adjustments.
True
False
The tire balancing machine:
uses weights attached to wheel rims to minimize static and dynamic rotational variations
spins the wheel hard enough to balance the tire and wheel materials together
is used to mount/dismount a tire to/from the rim
uses weights to add mass to the wheel to prevent it from bouncing too much while driving
A hydraulic shop jack for the following except:
support heavy vehicle components to prevent unwanted movement
should be used for lifting a vehicle
as a primary lift support for a vehicle
compress suspension components to prevent sprung components from moving rapidly
What does the compressor do in a pneumatic system?
Lubricates the system
Filters the air
Compresses the air
Cools the air
What is pneumatics?
The study of air movement and its phenomena.
The physical science and technologies associated with the mechanics of pressurized gases.
The study of hydraulic systems and their applications.
The technology of controlling mechanical properties of gases.
What is the main power source for a pneumatic impact wrench?
Electricity
Compressed air
Batteries
Gasoline
What is the first step you should take before performing maintenance on a pneumatic tool?
Remove all accessories
Disconnect the air supply
Apply oil to the moving parts
Consult the user manual
