Inspect the air tool.
Has the motor been oiled?
Is the tool’s air inlet clean?
Can the tool’s spindle
be turned by hand?
Is the tool’s exhaust
This silencer shows
evidence of oil.
This air motor received
Notice, the puddle of oil
“The spindle won’t turn.”
This usually indicates
Generally, broken vanes
indicate that the motor has
not been oiled regularly.
❑ Affix a 1/2" (12 mm) square piece of reflective tape to the
tool’s spindle or pad.
❑ Aim the Laser Pointer at the reflective tape and run the tool.
(Operational distance: 2"/50 mm to 20"/500 mm)
❑ Read RPM. (Notice: Refer to User’s Manual for more detailed
❑ Connect Air Gauge and air supply hose to the air inlet of the tool.
❑ Run the tool and adjust air supply pressure to 90 PSIG (6.2 Bar).
Condition of Coupler and Plug
❑ Check for wear or damage to coupler and/or plug.
❑ Can the I.D. of the plug supply enough air to the tool?
Condition of Air Hose
❑ Check to see if the hose is frayed or cracked?
(see “Cost of an Air Hose Leak” on reverse side)
❑ What is the length of the hose?
❑ Match length and I.D. of hose to air requirement of tool.
❑ Is there a hose reel?
Condition of Air Hose (Continued)
❑ How many coupler connections exist from the drop to
❑ Are there any “T’s” or a manifold at the workbench?
❑ How can Dynaswivelprolong the life of the hose?
❑ FRL – is it present? If yes, is it working?
❑ Filled with oil? Set for proper lubrication?
❑ What type of oil? (Weight, Non-detergent vs. Detergent – Notice:
Non-detergent oils contain little to no solvents. Air Tool Oils with
“conditioner” usually contain solvents. Example: Both Marvel
Air Tool Oil and MarvelMystery Oil contain mineral spirits,
a common solvent used as paint thinner.)
❑ Are there reducer bushings being used to connect the air supply
to the FRL?
❑ What size is the fitting connecting the FRL to the air line that is
supplying the air to the workbench?
❑ Are there any “T’s” or manifolds coming directly off the FRL?
❑ What material is the pipe that is carrying the air supply?
