Pressure Relief Procedure

Follow the Pressure Relief Procedure when-
ever 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, splash-
ing fluid and moving parts, follow Pressure Relief
Procedure when you stop spraying and before clean-
ing, checking, or servicing the equipment.
RPS 2900 Pump Fluid Pressure Relief
1. Set hydraulic valve to OFF position.
2. Run engine at half throttle.
3. Place empty pail under paint guns to catch drain-
age.
4. Relieve hose pressure through guns. Use Program-
mable Skipline Controller to trigger each gun for at
least 3 seconds each.
Always relieve pressure with the guns, not with the fil-
ter drain valves. Using the filter drain valves can
cause damage, and prevent them from sealing in the
close/spray positions.
