Service and maintenance
Maintenance schedule
The frequency of the following maintenance checks depend upon the material being sprayed (amount and
kind). The booth operators and maintenance technicians should perform these checks at regular intervals
to reduce fire hazards, maintain booth efficiency, prevent freshly painted objects from becoming blemished,
and hinder booth corrosion and wear. Adjust the frequency of the checks according to local guidelines and
actual usage.
See “Daily maintenance” (page 16), “Monthly maintenance” (page 26), “Yearly maintenance” (page 29),
and “General service procedures” (page 36) for full service procedures.
