MAINTENANCE

9.4 AIR BLAST SENSOR WASHER

The air blast sensor washer needs little routine maintenance. Replace the two large O-rings on the base of the washer head and the sensor sealing O-ring if they become cut or dirty or if there is evidence of water leaking into the washer head. The three O-rings are available as a kit (PN 24053-00).

See Figure 9-2 for replacement parts.
