NOTE: Before you check or repair the meter, be sure all
other valves, controls, and the pump are operating prop-

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
cleaning, checking, or servicing the equipment.
1. Turn off the power supply to the pump.
2. Trigger the valve into a waste container to relieve
pressure.
3. Open any bleed-type master air valves and fluid
drain valves in the system.
4. Leave the drain valve open until you have com-
pleted repairs and are ready to pressurize the sys-
tem.
