Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief
Procedure when you stop spraying and before clean-
ing, checking, or servicing the equipment.
NOTE: The fittings on the pressure relief hoses are zinc
plated carbon steel. The hoses are cured with sulfur.
Check your materials for compatibility with zinc plating
and sulfur before reusing any material that passed
through them, as it may inhibit curing.
