2. For remote pressure pot, hold gun parallel to floor
and adjust fluid pressure at 8 to 10 inch (203 to
254 mm) fluid stream. See Fig. 3.
For 2-quart remote pressure pot:
Set at 4 to 6 psi (0.28 to 0.42 bar).

Set at 8 to 10 psi (0.56 to 0.70 bar).
NOTE: Heavier fluids or longer fluid hoses require
greater pressures.
WARNING
Over-pressurizing the accessory remote pres-
sure pots can cause serious injury. To reduce
the risk, never exceed 50 psi (0.35 MPa,
3.5 bar) Maximum Inlet Fluid Pressure.

Restricting the trigger and fluid needle travel by
continuously spraying with the fluid adjustment
knob closed (turned clockwise), will cause
accelerated abrasive wear on the fluid needle and
wear on the trigger.
For best results, adjust fluid flow at the pressure
source or use a different size needle/nozzle/air cap
combination.
