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.
