Dynabrade: Performance Assurance


Performance Assurance
Air Tool and Air System Inspection/Diagnosis
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
(muffler/silencer) clean?
This silencer shows
evidence of oil.
This air motor received
“Last-Rites Oil.”
Notice, the puddle of oil
appears clean.
“The spindle won’t turn.”
This usually indicates
broken vanes.
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
PSI Gauge
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
the workbench?
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?
Black Iron?
