A NOTICE TO INTERNATIONAL DISTRIBUTORS:
International Distributors are responsible for

Please read and understand manual fully prior
to operating any machinery.
IMPORTANT
(Pertinent to blast machines)
WARNING
Before operating any abrasive blast cleaning equipment
READ ALL operating and maintenance instructions.
Personal protective equipment is REQUIRED when using
this type of equipment. Operator MUST be equipped with
heavy canvas or leather gloves, aprons, and arm protectors.
Safety shoes and hearing protection MUST be worn when
required. NIOSH approved air fed respirators (helmets)
furnished with at least Grade D breathing air MUST be used
for protection against dust inhalation. Air MUST be ltered
and monitored for Carbon Monoxide.
DANGER.
Use of Abrasive cleaning equipment with silica sands may
produce a heavy concentration of silica dust. Breathing this
dust can produce “Silicosis”, a permanent lung disease.
Depending upon the object to be cleaned, blasting, even
with non-silica abrasives, may release hazardous dust
particles into the air that can cause permanent lung
damage. Failure to use NIOSH approved air fed respirator
(helmet) may cause SERIOUS lung DAMAGE. This warning,
as to the proper use of an approved respirator (helmet),
applies not only to the operator, but extends to all those
working in or around the blasting area, such as pot tenders,
painters, supervisors, etc.
CAUTION
Blast cleaning equipment and components are subjected to
wear and deterioration.
• Keep your equipment in good operable condition.
• MAINTAIN nozzle control at all times during operation.
• INSPECT machine, nozzles, hoses, and couplings.
• Inspect, clean, or replace helmet lens and lters frequently.
• Ground equipment to AVOID electrical shock.
• DO NOT operate any machine without thorough knowledge
of machine operation.
Carefully READ the INSTALLATION, OPERATING, AND
MAINTENANCE directions supplied with the machine from
the factory. If you do not have a copy, please contact your
employer (supervisor) or MMLJ Inc.

PELIGRO
Es posible que el uso de los equipos de limpieza por
abrasion con arenas sillceas provoque una concentracion
pesada de polvo sillceo. Este polvo, al ser respirado,
puede producir “silicosis”, que es una enfermedad
pulmonar permanente. Dependiendo del objeto que va
a limpiarse, es posible que la limpieza a chorro, aun con
abrasives no silfceos, provoque el escape de partlculas
de pohio pel igrosas en el aire que pueden causar dano
pulmonar permanente. Si nose usan los respiradores
(cascos) alimentados por aire, aprobados por NIOSH,
puede provocarse un GRAVE DANO a los pulmones. Esta
advertencia sabre el uso adecuado de un respirador (casco)
aprobado no solo se aplica al operador sino que comprende
