1. Empty and rinse after each use. Fill the can withwater and pressurize the can. Flush the dischargeline to ensure that the unit is clean.
2. lf discharge liquid does not foam, the orifice may beblocked.
3, To clean, disconnect the plumbing from the tank atthe large coupling nut,
4. Remove the in-line filter trom the discharge side andclean if necessary.
5. The fluid oritice is located behind the filter.
Clean it with the pick stored in the bottom of the tankhandle or blow it clean with air. Securely reassem-
