Pails
Solvent and oil/based fluids: follow local code. Use
only conductive metal pails, placed on a grounded sur-
face such as concrete.
Do not place pail on a nonconductive surface such as
paper or cardboard which interrupts grounding
continuity.
Grounding a metal pail: connect a ground wire to the
pail by clamping one end to pail and other end to a true
earth ground such as a water pipe.
To maintain grounding continuity when flushing or
relieving pressure: hold metal part of spray gun firmly
to side of a grounded metal pail. Then trigger gun.
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Engage the gun trigger lock. Refer to the separate
instruction manual provided with gun for safety fea-
tures and how to engage the trigger lock.
2. Turn the unit off.
3. Disengage the gun trigger lock and trigger the gun
to relieve residual fluid pressure.
Hold metal part of the gun in contact with grounded
metal pail. Use minimum pressure.
4. Re-engage gun trigger lock and turn Prime Valve to
the open (priming) position.
NOTE: The valve handle can move both clockwise and
counter clockwise and can face different directions.
NOTE: If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved after following
the steps above, VERY SLOWLY loosen tip guard
retaining nut or hose end coupling to relieve pressure
gradually, then loosen completely. Clear hose or tip
obstruction.

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.
