Reorder No. D13.10 Performance Assurance AIR TOOL AND AIR SYSTEM INSPECTION/DIAGNOSISAIR TOOL INSPECTION □ Is the tool's air inlet clean? □ Is the tool's exhaust (muffler/silencer) clean? □ Has the motor been oiled? This silencer shows evidence of oil. This air motor received “Last-Rites Oil.” Notice, the puddle of oil appears clean. □ Can the tool's spindle be turned by hand? “The spindle won’t turn.” This usually indicates broken vanes. Generally, broken vanes indicate that the motor has not been oiled regularly. Tachometer □ 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 instructions.) 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 Dynaswivel® prolong the life of the hose? Filter-Regulator-Lubricator □ 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 Marvel® Mystery 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

Equipment Check: Random Orbital Sander □ 90 PSIG (6.2 Bar) is the required operating air supply pressure. Check the air pressure at the sander while it is running. Note: Promote the use of Dynabrade maximum flow plugs and couplers to ensure proper airflow. □ Confirm that the tool is running at the rated “Free Speed” RPM. On an average a 10,000 RPM non-vacuum sander will run at 9,500 RPM; a 12,000 RPM non-vacuum sander will run at 11,500 RPM. A vacuum sander normally runs slightly slower. □ Inspect the balancer bearing (pad bearing). Remove the back-up pad and rotate the balancer bearing shaft...
