Particles blown by compressed air are hazardous. DO NOT exceed
15 psi (103 kPa) nozzle pressure when drying parts with compressed
air. Use a maximum of 30 psi (207 kPa) when cleaning components.
DO NOT direct compressed air against human skin. Failure to fol-
low this warning may cause injury or death. Make sure air stream is

container of clean diesel fuel for
10 seconds. No air bubbles should
be visible from the cold start
