OPERATION MANUAL

IMPORTANT: Read and follow all instructions and SAFETY PRECAUTIONS
before using this equipment. Retain for future reference.

SAFETY PRECAUTIONS

This manual contains important information that ALL users should know and understand BEFORE
using the equipment. This information relates to USER SAFETY and PREVENTING
EQUIPMENT PROBLEMS. To help you recognize this information, we use the following terms to
draw your attention to certain equipment labels and portions of this manual. Pay special attention
to any label or information that is highlighted by one of these terms.:

WARNING

CAUTION Important information that tells how to prevent damage to equipment.

NOTE Information that you should pay special attention to.

FIRE AND EXPLOSION

Solvents and coating materials can be highly flammable or combustible, especially when sprayed.
¾ Work stations must be provided with adequate ventilation/exhaust to prevent the build-up of

flammable vapours.

¾ Smoking and naked flames must not be allowed in the spraying or mixing areas.
¾ Fire extinguishing equipment must be provided in the spraying and mixing areas.

Users must comply with all local and national codes of practice and insurance company requirements
governing ventilation, fire precautions, operation maintenance and housekeeping of work stations.

HALOGENATED HYDROCARBON SOLVENTS – for example 1,1,1-Trichloroethane and Methylene
Chloride can chemically react with aluminum and galvanised or zinc coated parts and cause an
explosion hazard. Read the label and data sheet of the material you intend to spray.

This equipment, as supplied, is suitable for use with Halogenated Hydrocarbons and the user must
ensure that all other equipment in the system is also suitable for use with these materials. DO NOT
SPRAY MATERIALS CONTAINING THESE SOLVENTS EXCEPT WITH EQUIPMENT
SPECIFICALLY DISIGINATED BY THE MANUFACTURER AS BEING SUITABLE FOR SUCH USE.

STATIC ELECTRICITY – is generated by fluid moving through pipes and hoses. A static spark,
capable of igniting certain solvents and coating materials, could be produced by high fluid flow rates.
To prevent the risk of fire or explosion, earth continuity to the spray equipment and object being
sprayed should be maintained.

PERSONAL PROTECTIVE EQUIPMENT

TOXIC VAPOURS – When sprayed, certain materials may be poisonous, create irritation or otherwise
be harmful to health. Always read carefully all labels and safety/performance data for the material
being sprayed and follow any recommendations. IF IN DOUBT, CONSULT THE MATERIAL
SUPPLIER.

Important information to alert you to a situation that might cause serious injury or
loss of life if instructions are not followed.

SAFETY WARNING

− 1 −

¾ The use of respiratory protective equipment is recommended at all times when spraying. The

type of respiratory protective equipment used must be compatible with the material being
sprayed and the level of concentration.

¾ Always wear eye protection when spraying or cleaning the equipment.
¾ Gloves must be worn for spraying or cleaning the equipment when certain coating materials and

solvents are used.

TRAINING

Personnel should be given adequate training in the safe use and maintenance of this equipment.
Training courses on all aspects of the equipment are available. For details contact your local
representative. The instructions and safety precautions contained in this literature and the literature
supplied with the coating material should be read and understood before the equipment is used.

MISUSE

¾ All spray guns project particles at high velocity and must never be aimed at any part of the body.
¾ Never exceed the recommended safe working pressures for any of the equipment used.
¾ The fitting of non-recommended or non-original accessories or spare parts may create hazardous

conditions.

¾ Before dismantling the equipment for cleaning or maintenance, all pressures, air and material,

must be isolated and released.
The disposal of non-metallic materials must be carried out in an approved manner. Burning may
generate toxic fumes. The removal of waste solvents and coating materials must be carried by an
authorized local waste disposal service.

The materials used in the construction of this equipment are (bearing in mind the warning on
Halogenated Hydrocarbon) solvent resistant enabling the equipment to be cleaned using gun
cleaning machines. However, this equipment must not be left inside the gun cleaning machine for
prolonged period of time after the automatic cleaning cycle has been completed

The solvents used in the gun cleaning machine should be regularly checked to insure that the
equipment is not flushed through with contaminated material. Follow the recommendations of the
machine manufacturer.

NOISE LEVENLS

The continuous A-weighted sound pressure level of this spray gun may exceed 85 dB(A) depending
on the air cap/nozzle set-up being used. Sound levels are measured using an impulse sound level
meter and analyser, when the gun is being used in a normal spraying application. Details of actual
noise levels produced by the various air cap/nozzle set-ups are available on request.

DESCRIPTION

MSV-512 has been developed aiming at high transfer efficiency. The most merit of this gun is that
fine atomization and high transfer efficiency can be obtained with less air consumption comparing
with the existing guns. LVMP stands for Low Volume Medium Pressure; Low Volume means low air
consumption and Medium Pressure means medium atomization air pressure.

CAUTION:

MSV-512 LVMP gun is suitable for almost all of general paint except for high corrosive and high
abrasive paint. If these paint may be used, thorough cleaning must be done frequently. Also, the
replacement of the parts will be more frequent. Please ask the supplier for advice if you have any
doubt of the paint.
