Vacuum Tire
1. Install deflators and check for foreign substances as explained on the preceeding page.
2. Connect shop air to the air inlet port on the rear of the NTF-15. Verify pressure indicated on panel mounted Air
Pressure gauge is between 120 - 150 PSI.
3. Turn both panel valves to VACUUM TIRE.
4. Remove deflator and connect Pressure Gauge (on the end of the NTF-15 coiled green hose) to the tire valve stem.
Squeeze handle to vacuum the tire. Periodically release the handle to observe the vacuum level. Do not vacuum

Note: While not using the NTF-15 to fill or vacuum tires, generate Nitrogen and increase the Nitrogen
pressure in the internal storage tank by turning both panel valves to STANDBY.
Note: While using the NTF-15, the automatic drain feature of the filters may activate to remove excess
water and oil. This is normal with the standard operation of the unit.
If your application requires an inlet pressure of 100 - 119 PSI, an
adjustment to the automatic pressure switch may be required.
