Warnings
The following warnings are for the setup, use, grounding, maintenance, and repair of this
equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols
refer to procedure-specific risks. When these symbols appear in the body of this manual or on
warning labels, refer back to these Warnings. Product-specific hazard symbols and warnings not
covered in this section may appear throughout the body of this manual where applicable.
FIRE AND EXPLOSION HAZARD
Flammable fumes, such as solvent and paint fumes, in work area can ignite or
explode. Paint or solvent flowing through the equipment can cause static sparking.
To help prevent fire and explosion:
•Use equipment only in well ventilated area.
•Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric
lamps, and plastic drop cloths (potential static arc).
•Ground all equipment in the work area. See Grounding instructions.
•Never spray or flush solvent at high pressure.
•Keep work area free of debris, including solvent, rags and gasoline.
•Do not plug or unplug power cords, or turn power or light switches on or off when
flammable fumes are present.
•Use only grounded hoses.
•Hold gun firmly to side of grounded pail when triggering into pail. Do not use pail
liners unless they are antistatic or conductive.
•Stop operation immediately if static sparking occurs or you feel a shock. Do
not use equipment until you identify and correct the problem.
•Keep a working fire extinguisher in the work area.

nozzle tip clogs while spraying, follow the Pressure Relief Procedure for
turning off the unit and relieving the pressure before removing the nozzle tip to
clean.
•Equipment maintains pressure after power is shut off. Do not leave the
equipment energized or under pressure while unattended. Follow the Pressure
Relief Procedure when the equipment is unattended or not in use, and before
servicing, cleaning, or removing parts.
