| Can a tool be attached to a compressor that produces higher CFPM than needed? |
|
Definition
| Yes, just means you can have more tools running as well, or use the tool longer. |

| Pre Dive Procedure: Pneumatic Tools. |
|
Definition
1) Clean, inspect fittings and blow out airlines.
2) Visually inspect tool for defects or discrepancies
3) Lubricate tool. Small tools add 1-2 tablespoons of oil, large tools add 1/4 - 1/2 a cup or oil. (into air inlet)
4) Grease (if fittings fited)
5) Hook up air lines.
6) Run tool at low throttle to circulate oil into but not through the tool. |

Definition
1) Run tool on surface to blow out water.
2) Rinse tool in fresh water
3) Dry tool-clean off excess oil grease with solvent.
4) Disconnect tool, add lubricant to air inlet.
5)Reconnect tool run at low throttle to circulate oil into tool - grease if fittings provided.
6) Visually inspect. Note repairs, or report defects.
7) Stow Tool in proper storage. |

Term
| Portable Compressor check. |
|
Definition
1) Ensure machines is sitting level (keeps oils and liquids in correct location to be absorbed)
2) Check coolant
3) Check Fuel (gas and Diesel)
4) Check oil (engine and compressor)
5) Check belts
6) Air valves (ensure inline oilers, filled if fitted)
7) Start machine, log start time.
8) Blow lines, inspect, clean fittings, hook up hoses, lock, blow through
9) Lubricate and hookup tools. |

Definition
is designed to ensure that the compressor does not start under load. (usually found in LP compressors)
This is most commonly accomplished by flyweights which fall to their resting position when the compressor stops rotating. This presses on a small valve which then opens and vents the air |
