SAFETY

This section contains important safety information for the equipment. Careful observance of the safety information will 
help prevent physical injury, damage to the equipment, and extend the equipment life.

Equipment Labels

The following safety labels may appear on the equipment. If ignored, physical injury, death, or equipment damage may 
occur. Read the safety information in the equipment operation guides before installing, operating, or maintaining the 
equipment.

 

WARNING Electrical Shock Hazard

This symbol indicates the presence of life-threatening voltages. Never access areas labeled 
as such without first taking appropriate safety precautions: locking out power, verifying no 
voltage is present on circuits prior to maintenance activities, etc.

  

WARNING Flying Debris/Loud Noise

Eye and ear protection are required during operation. Removing the abrasive feed tube from 
the nozzle while under pressure will blow abrasive particles into the air, getting into eyes, and 
could contaminate tools and machines.

  

No Open Flame

Do not allow smoking near the machine. Do not operate the equipment in an explosive 
atmosphere. Make sure that no ignition source (such as open flame or electrostatic 
discharge) is nearby the equipment. Do not store flammable materials near the equipment. 
Do not use equipment in or around flammable gases or liquids. Do not allow explosive or 
flammable vapors to accumulate in the area of the equipment. Proper ventilation in the work 
area will assist in dissipating the accumulation of gas, vapor, and fumes. Be especially careful 
when cutting materials that create sparks, such as titanium—these can ignite gases in the tank.

  

Lock Out Power

Never do maintenance on the equipment with the main AC disconnect ON, unlocked, or with 
the pump in operation. Always follow standard lockout/tagout procedures.

  

Wear Eye Protection

Always wear approved safety glasses whenever cutting. Regular glasses do not provide 
sufficient eye protection! The garnet abrasive is not a chemical irritant, but if not quickly 
washed out, it can injure an eye just as any sand would. In addition, tank water could contain 
particles from the material or chemical irritants. Have an eyewash station located near the 
work area in the event abrasive spray splashes into the eyes.

Read the product labels and refer to product Safety Data Sheets (SDS) to identify properties 
and hazards of chemical products and materials referenced in this document. Handle in 
accordance with good industrial hygiene and safety practice. Use personal protective 
equipment as specified in the SDS.
