Pressure Relief Procedure
when y ou stop di spens i ng and befo re cleaning,
Get
• Use equipment only in well ventilated area.
• Do not fill fuel tank while engine is running or hot; shut off engine and let it cool. Fuel is
flammable and can ignite or explode if spilled on hot surface.
• Eliminate all ignition sources; such as pilot lights, cigarettes, portable electric lamps, and
plastic drop cloths (potential static arc).
• Keep work area free of debris, including solvent, rags and gasoline.
• Do not plug or unplug power cords, or turn light switches on or off when fl ammable fumes
are present.
• Ground all equipment in the work area. See
• Use only grounded hoses.
• Hold gun firmly to side of grounded pail when triggering into pail.
• If the re is static sparking or you feel a shock,
equipment until you identify and correct the problem.
• Keep a working fire extinguisher in the work area.
THERMAL EXPANSION HAZARD
Fluids subjected to heat in confined spaces, including hoses, can create a rapid rise in pressure
due to the thermal expansion. Over-pressurization can result in equipment rupture and serious
injury.
• Open a valve to relieve the fluid expansion during heating.
• Replace hoses proactively at regular intervals based on your operating conditions.

WARNING
BATTERY HAZARD
The battery may leak, explode, cause burns, or cause an explosion if mishandled.
• Only use the battery type specified for use with the equipment. See
• Battery maintenance must only be performed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized personnel away from battery.
• When replacing the battery, use the same lead-acid automotive battery, with 800 CCA
minimum, specified for use with the equipment. See
• Do not dispose of battery in fire. The battery is capable of exploding.
• Follow local ordinances and/or regulations for disposal.
• Do not op en or mu til ate the battery. Rel eas ed electrolyte has bee n known to be harmfu l to
the skin and eyes and to be toxic.
• Remove watches, rings, or other metal objects.
• Only use tools with insulated handles. Do not lay tools or metal parts on top of battery.

Important Two-Component Material Information
Important Two-Component Material Information
Isocyanate Conditions
Spraying or dispensing materials containing
isocyanates creates potentially harmful mists,
vapors, and atomized particulates.
Read material manufacturer’s warnings and
material MSDS to know specific hazards and
precautions rel ate d to isocyanates.
Prevent i nh ala tio n of isocy ana te mists, vapors,
and atomized particulates by providing sufficient
ventilation in the work area. If sufficient ventilation
is not available, a supplied-air respirator is required
for everyone in the work area.
To prevent contact with isocyanates, appropriate
personal protective equipment, including
chemically impermeable gloves, boots, aprons,
and goggles , is also requi red for everyone in the
work area.
Moisture Sensitivity of Isocyanates
Cross-contamination can result in cured
material in fluid lines which could cause serious
injury or damage equipment. To prevent
cross-contamination of the equipment’s wetted
parts,
never
interchange component A (is ocyanate)
and component B (resin) parts.
Isocyanates (ISO) are catalysts used in two
component foam and polyurea coatings. ISO will
react with moisture (such as humidity) to form small,
hard, abrasive crystals, which become suspended in
the fluid. Eventually a film will form on the surface
and the ISO will begi n to gel, inc reas ing in viscosity. If
used, this partially cured ISO will reduce performance
and the life of all wetted parts.
The amount of film formation and rate of crystal lization
varies depending on the blend of ISO, the humidity,
and the temperature.
Material Self-Ignition
Some materials may become self-igniting if applied
too thickly. Read material manufacturer’s warnings
and material MSDS.
Keep Components A and B Separate
Cross-contamination can result in cured
material in fluid lines which could cause serious
injury or damage equipment. To prevent
cross-contamination of the equipment’s wetted
parts,
never
interchange component A (is ocyanate)
and component B (resin) parts.
To prevent exposing ISO to moisture:
• Always use a sealed container with a desiccant
dryer in the ve nt, or a nit rogen atmosphere.
store ISO in an open container.
• Keep the ISO lube pump reservoir (if installed) filled
with appropriate lubricant. The lubricant creates a
barrier between the ISO and the atmosphere.
• Use only moisture-proof hoses compatible with
ISO.
• Never use reclaimed solvents, which may contain
moisture. Always keep solvent containers closed
when not in use.
• Always lubricate threaded parts with ISO pump oil
or grease when reassembling.
Never

Important Two-Component Material Information
Foam Resins with 245 fa Blowing Agents
Some foam blowing agents will froth at temperatures
above 90°F (33°C) when not under pressure,
especially if agitated. To reduce frothing, minimize
preheating i n a circulation system.
Changing Materials
Changing the material types used in your equipment
requires special attention to avoid equipment damage
and downtime.
• When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
• Always cl ea n th e flui d i nl et s trai ne rs after fl us hi ng.
• Check with your material manufacturer for chemical
compatibility.
• When changing between epoxies and urethanes
or po ly urea s, disasse mbl e and clean all fluid
components and change hoses. Epoxies often
have amines on the B (hardener) side. Polyureas
often have amines on the B (resin) side.

Total system watts used by system, based on maximum heated hose length of 310 ft (94.5 m) for
each unit.
* Full load amps available for auxiliary equipment when all bare-system components are operating
at maximum capabilities. Available auxiliary current is based on 310 ft (94.5 m) of heated hose.
An additional 3.0 amps of auxiliary current is available for each 50 ft (15.2 m) section of heated
hose that is not used.
Available auxiliary current will be less when the engine is de-rated for site altitude. Reduce the
Available Auxiliary Current in the chart by 2.5 Amps per 1000 ft (300 m) elevation increments. If the
available auxiliary current is less than zero, the system configuration may not support the full load
at that altitude.
