Safety and Handling

This chapter contains important information on the safety, handling, and use of
your HighLine spray gun.

Before installing the spray gun and start-up, carefully read all the
technical and safety documentation included in this manual. Pay
special attention to the information to know a nd understand the
operation and conditions of use of the unit. All of the information
is aimed at enhancing user safety and avoiding possible
breakdowns derived from the incorrect use of the gun.

presents information to alert of a situation that might cause
serious injuries if the instructions are not followed.

presents information that indicates how to avoid damage to the
spray gun, or how to avoid a situation that could cause minor
injuries.

is relevant information of a procedure being carried out.

Careful study of this manual will enable the operator to know the characteristics of
the spray gun and the operating procedures. By following the instructions and
recommendations contained, you will reduce the potential risk of accidents in the
installation, use, or maintenance of the spray gun. You will provide a better
opportunity for incident-free operations for a longer time, greater output, and the
possibility of detecting and resolving problems fast and simply.

Keep this operations manual handy for future reference to useful information. If you
lose the manual, contact ArmorThane for a new copy.

HighLine Spray Gun

Important Safety Information

The HighLine spray gun has been designed and built for the application of
polyurethane and polyurea chemical systems, and polyurethane foam chemical
systems.

The design and configuration of the HighLine spray gun does not
allow its use in potentially explosive atmospheres or exceeding
the pressure and temperature limits described in the technical
specification of this manual to be exceeded.

Always use liquids and solvents that are compatible with the spray gun. If in doubt,
contact the ArmorThane Technical Department.

When working with the spray gun, it is recommended that the operator wear
suitable clothing and personal protection, including, without limitation, gloves,
protective goggles, safety footwear, and face masks. Use breathing equipment
when working with the spray gun in enclosed areas or in areas with insufficient
ventilation. The introduction and follow up of safety measures must not be limited
to those described in this manual. Before beginning to work with the spray gun, a
comprehensive analysis must be made of the risks derived from the products to be
dispensed, the type of application and the working environment.

To prevent possible injury caused by incorrect handling of
the materials and solvents used in the process, carefully read
the Material Safety Data Sheets (MSDS) provided by
ArmorThane.

Deal with the waste according to current regulations.
To avoid damage caused by the impact of pressurized fluids,

do not open an y connection or perform ma intenance work on
components subject to pressure until the pressure has been
completely eliminated.

Use suitable protection when opera ting, maintaining, or be ing
present in the area where the equipment is functioning. This
includes, but is not limited to, the use of protective goggles,
gloves, shoes, and safety clothing and breathing equipment.

The equipment includes components that reach high
temperatures and can cause burns. Hot parts of the
equipment must not be handled or touched until they are
completely cool.

To prevent serious injury through crushing or a mputation, do
not work with the equipment without the safety guards
installed on the moving parts. Ensure that all the safety
guards are correctly reinstalled at the end of the repair or
maintenance work of the equipment.

Installation & Start-Up

When working with the HighLine spray gun, or performing
maintenance work, wear suitable safety protection in accordance
with the recommendations and specifications provided by
ArmorThane.

1. Ensure the coupling block manual valves (5) are closed by turning them to the

full clockwise position.

Excessive force closing or opening the manual valves may result
in damage to the manual valves and/or coupling block.

2. CLOSE the air safety slide valve (22) (downward/rearward position)

3. Connect the spray gun to the coupling block using the supplied hex key wrench.

Ensure coupling block gaskets (6) are in place.

4. Connect the air supply to the air safety slide valve.

The material delivery hoses are color-coded red and blue,
allowing the user to recognize them. The red corresponds to
the isocyanate (A) and the blue to the resin (B). To avoid
connection errors, the coupling connections of the
isocyanate (A) and resin (B) hoses are also different sizes,
which makes it difficult to swap connections.
