Safety Labels
Safety
Label Description
Wear Gloves
Since bacteria in the tank water can build up, even a seemingly minor break in the skin can introduce
harmful bacteria into a wound. Always wear protective gloves if you have cuts or open wounds on your
hands. When setting up material for cutting, always wear gloves that provide protection against sharp
metal edges.
Electrical Hazard
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 present on circuits prior
to maintenance activities, etc.
Lock Out Power
Never open or do maintenance on the OMAX equipment with the main AC disconnect ON or unlocked,
or while the pump unit is operating. Always follow standard lockout/tag-out procedures.
Don’t apply power to the equipment while maintenance work is in progress. Always lock the main
power to the OMAX pump off at its source.
Eye Protection
Always wear approved safety goggles whenever cutting. Regular glasses are not sufficient eye
protection!
Ear Protection
Always wear hearing protection while in the vicinity of the OMAX. When cutting in air, noise levels can
exceed 120 dB.
Flying Debris/Loud Noise
Eye and ear protection are always required during operation.
Emergency Stop Switch
Pushing the emergency stop switch in immediately shuts down water pump and abrasivejet operation.
The emergency stop switch should be used only for real emergencies. When pressed, the OMAX loses
important machine position. The equipment cannot be restarted until the emergency stop switch is
reset.

Safety Label Description
Never operate the OMAX with any of its protective guards or covers removed or
rendered inoperative.
Never make unauthorized alterations to the equipment or components.
Never operate the OMAX with any of its protective guards or covers removed or
rendered inoperative.
Never place your hands in the vicinity of the nozzle while cutting.
Seek immediate medical attention in the event of a waterjet injury. Injuries caused
by high-pressure waterjets are serious. Do not delay!
Never step, stand or walk on the support slats. They are weakened with continued
cutting and may collapse under your weight.
Never place your hands or fingers in areas where they are in danger of becoming
pinched during equipment operation.
Never operate the equipment with the protective covers missing, exposing
yourself to dangerous mechanical and electrical hazards.
Removing the abrasive feed hose from the nozzle while still under pressure will
blow abrasive particles into the room air, getting into eyes and contaminating tools
and machines.
Don’t spray the identified area with water or compressed air. Read the service and
maintenance guide for additional information.

Safety Precautions
Always observe the following safety precautions while operating your OMAX equipment. Carefully operated,
the OMAX is a safe, productive tool. When operated carelessly, serious injury can easily result.
Table Safety Requirements
Do
• Be careful when handling materials in the tank. Fingers can be caught between heavy parts and the
sharp edges of the support slats.
• Wear hearing protection while in the vicinity of the OMAX. When cutting in air, noise levels can
exceed 120 dB.
• Cut under water whenever possible. When water covers both the material being cut and the nozzle
tip, the noise level measured in the operator’s area drops to approximately 80 dB (refer to Figure 1-
6).
• Wear approved safety goggles whenever cutting. Regular glasses are not sufficient eye protection!
• Have an eyewash station located near the OMAX in the event abrasive spray splashes into your
eyes. 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 chemicals irritants.
• Treat all injuries with caution. Because bacteria in the water can build up, even a seemingly minor
break in the skin can introduce harmful bacteria into the wound. Any injury involving contact with the
water should receive immediate attention. Use antibacterial chemicals in the tank water (exception is
with EBBCO Closed Loop) to reduce this hazard, andalways wear protective gloves if you have cuts
or open wounds on your hands.
• Seek immediate medical attention in the event of a waterjet injury. Injuries caused by high-pressure
waterjets are serious. Do not delay! Inform the physician of the cause of the injury, what type of
waterjet project was being performed at the time of the accident, and the source of the water.
• When setting up material for cutting, wear gloves that provide protection against sharp metal edges
and waterborne microorganisms.
• Dispose of cutting wastes properly and in accordance with all local and federal regulations. The
OMAX produces two types of waste: the water used for cutting and the solid material that
accumulates in the catcher tank. Although the garnet abrasive itself is inert, the waste deposited
from the kerf material may require special handling.
• Because of inevitable water spills, cover the floor around the operator area with a nonslip material
such as a textured rubber mat or nonslip paint.

OMAX JetMachining® Center Operator’s Guide Safety First
1 - 6 400433D-EN
• Use only approved work platforms. Never climb on or around the equipment using makeshift
devices.
• Always use the muff on the abrasivejet nozzle. It helps keep the noise level low during machining
and reduces splashing of water and abrasive.
• Always use proper lifting equipment to handle heavy work materials.
• Always remove power from the equipment when finished using the JetMachining Center for the day.
Don’t
• Don’t operate the OMAX JetMachining Center without first being adequately trained on how to
operate it correctly and safely.
• Don’t allow nozzle movement while handling material in the tank. Stop the abrasivejet before making
any adjustments. Nozzle movement can exert up to 1,000 lbs (4.4 kN) of force, easily crushing any
hands or fingers caught between it and another object.
Note: It’s possible that the nozzle may move or become active during machine adjustments while
power is still applied.
• Don’t stand on the support slats. They are weakened by continued cutting and may not support your
weight.
• Don’t operate the OMAX with any of its protective guards or covers removed or rendered
inoperative.
• Don’t operate the OMAX in an explosive atmosphere. Machining titanium and certain other materials
can produce sparks. Never allow explosive or flammable vapors to accumulate in the area of the
OMAX.
• Don’t allow unauthorized personnel access to the machining area without providing proper
supervision.
• Don’t switch tank chemicals for bacterial control without first reading the manufacturing warnings on
the labels. Mixing different chemicals can create a hazardous situation.
• Don’t use silica sand as a cutting abrasive. Fine silica dust produced by the cutting process can lead
to silicosis, a serious lung disease.
• Don’t operate the machine in close proximity to other machines or electrical equipment as water can
spray or splash out of the cutting table area.
Pump Safety Requirements
Do
• Operate the OMAX pump only after reading this manual and receiving instruction from a qualified
operator.
• Stay in a location within easy reach of the emergency stop switch.
• Start the pump only when all side panels are securely in place.
• Maintain all protective guards and shutdown devices around the OMAX pump.
• Immediately notify responsible repair personnel whenever leaks are detected in high-pressure
fittings or connections.
• Follow the manufacturer’s recommendations for servicing the equipment and use only original
manufacturer replacement parts.
• Follow a periodic maintenance schedule that ensures proper equipment operation.
• At the conclusion of maintenance activities, clear all tools and rags from around the OMAX pump
before operating the equipment.
Don’t
• Don’t start the OMAX pump unless you know how to stop it.
• Never open or do maintenance on the OMAX pump with the main disconnect ON or unlocked, or
while the pump unit is operating. Always follow standard lockout/tag-out procedures.
• Don’t apply power to this pump while maintenance work is in progress. Always lock the main power
to the OMAX pump off at its source.
• Don’t make unauthorized alterations to the equipment or components.

• Don’t operate the abrasive waterjet for more than a few seconds when the standoff distance
between the water level and nozzle tip is greater than 1.5 inches. Above this height, the entrapped
air can allow the jet stream to easily travel through the water and strike the tank bottom with
sufficient force to cut through it.

Equipment Safety Features
The OMAX equipment provides several built-in safety features:
1. Emergency Stop Switch: Both the pump unit and controller are equipped with an emergency stop
switch. Push in the emergency stop switch to immediate shut down both the pump unit and the
abrasivejet.
2. Overpressure Protection: The pump has two types of overpressure protection. A factory set
mechanical safety valve provides a hard-plumbed, overpressure limit. The electronics for controlling
the pump also monitor system water pressure. Whenever it detects that the system pressure has
exceeded the factory set pressure limit, it stops the pump and displays 'Dead head of Pump' on the
pump display panel.
3. Electrical Protection: The variable frequency drive (VFD) provides electrical protection as well as
speed control for the pump’s main drive motor. A circuit breaker provides short circuit protection for the
charge pump motor. Circuit breakers protect the internal transformer and a 0.5 Amp fuse protects the
pump keypad.
4. Access Control Circuit: An optional OMAX Access Control Circuit (ACC) is available for all OMAX
tables. The ACC creates a designated safety zone around the OMAX JetMachining Center that
protects operators from injury when using the OMAX equipment. The access control circuitry
continually monitors two external switch contacts. Opening either switch immediately disables the
cutting process.
