Preventative Maintenance Chart procedures are located on reverse side.
Instructions for the Spray Pattern Test, Spray Volume Test, and cleaning the nozzles are contained in the User’s Manual.
The frequency set forth on this chart for daily, weekly, and monthly maintenance is considered maximum. Field experience suggests the more the Aerospray Slide Stainer is used the less frequently it
requires preventive maintenance. Do preventive maintenance at the level necessary to keep nozzle performance within specification and slides staining correctly.
Warning: Always wear eye and hand protection when performing preventive maintenance on the Aerospray Slide Stainer.
This Preventive Maintenance Chart may be reproduced in its entirety by Aerospray users.
*optional **Volume relationships between nozzles are as important as the actual volumes collected. Investigation should center on whether the nozzles are delivering close to the same volumes.
