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.
WARNING
FIRE AND EX
Flammable fumes, such as solvent and paint fumes, in work area can ignite or explode. 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).
•Keepwork
• Do not plug or unplug power cords, or turn power or light switches on or off when flammable
fumes are present.
• Ground all equipment in the work area. See Grounding instructions.
•Useonly
• 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.

Many solvents can degrade plastic parts and cause them to fail, which could cause serious
injury or property damage.
• Use only compatible water-based solvents to clean plastic structural or pressure-containing
parts.

Cavitation depends on the vapor pressure of the
pumped liquid, the system suction pressure, and the
velocity pressure. It can be reduced by changing any
of these factors.

temperature of the pumped liquid.

Pumped liquid viscosity is also very important but
normally is controlled by factors that are process
dependent and cannot be changed to reduce
cavitation. Viscous liquids are more difficult to pump
and more prone to cavitation.

Mount The Pump
To avoid serious injury from toxic fluid or fumes:
• Ventilate to a remote area. The pump
exhaust air may contain contaminants. See
Air Exhaust Ventilation, page 11.
• Never move or lift a pump under pressure. If
dropped, the fluid section may rupture. Always
follow the Pressure Relief Procedure, page 14,
before moving or lifting the pump.
1. Mount the pump so the exhaust port remains
clear of the production area. Exhaust air may
contain debris and condensation from the air
supply and air chamber.
Installation
2. Be sure the mounting surface can support the
weight of the pump, hoses, and accessories, as
well as the stress caused during operation.
3. For all mountings, be sure the pump is secured
with screws through the mounting feet. Always
mount the pump upright.
4. Make sure the surface is flat and that the pump
doesn’t wobble.
5. For ease of operation and service, mount the
pump so air inlet, fluid inlet and fluid outlet ports
are easily accessible.
