Additional Safety for Fume Extractors

Long-term respiratory damage, toxicity, cancer, or birth defects can occur from inhaling fumes, vapors, and particulates generated while cutting substrates without adequate ventilation, exhaust, and fume extraction. All users must be properly trained on the potential hazards, control measures, manufacturer’s operating procedures, use of personal protective equipment (PPE), emergency procedures, and safety precautions for CNC laser operations. To reduce these risks, operator and bystanders MUST completely heed the warnings below.

TOXIC MATERIALS. Exposure to certain types

of fumes can result in serious, potentially deadly health effects. To reduce this risk, research toxicity of material types you work with, and always seek to minimize/eliminate exposure to yourself and others. Obtain the Safety Data Sheet (SDS) from material manufacturer BEFORE operations, and never knowingly engrave or cut a workpiece that has been treated with or contains material that releases toxic byproducts when heated.

TOXIC FUMES. Cutting or engraving metals and plastics give off highly toxic fumes, vapors, and air particulates containing zinc, lead, beryllium, cadmium, mercury, fluorine, hexavalent chromium, chlorine gas, and many others. These fumes and air contaminants can damage the machine and harm your health. If the fume extractor or extraction fan is malfunctioning, immediately stop operations and correct the issue.

ADEQUATE VENTILATION. Only use CNC lasers in spaces with adequate ventilation. Some materials can produce vapors and fumes that may irritate the nose, throat, and respiratory tract, or cause suffocation. Only operate CNC lasers with a fully functioning extraction fan and fume extractor. Use additional personnel to monitor operator from outside the operating area in the event of equipment failure.

EXTRACTION FAN. To effectively extract fumes and particulates from the machine during operations, use an extraction fan rated for a minimum of 200 CFM (Cubic Feet per Minute) at 6" static pressure.

FUME EXTRACTION. CNC lasers must be equipped with a fume extractor that uses MERV 15+ or HEPA filters. NEVER modify fume extractor or bypass safety features. Only operate fume extractor with all filters and covers in place during operation. If any filter is missing or has been replaced with a non-specification filter, the fume extractor will not properly filter contaminated air and will be unsafe to use.

INSPECTIONS/MAINTENANCE. Always inspect exhaust ducting and fume extractor for leaks prior to operations. Repair or replace defective components before starting.

FILTER CLEANING/DISPOSAL. Filters must be changed regularly according to the frequency of use, or as specified by the manufacturer. When servicing filters, make sure operator and any bystanders are wearing Personal Protective Equipment (PPE). When vacuuming filters and cabinet, only use a shop vacuum that is equipped with a MERV 15+ or HEPA filter, or dangerous particulates may be spread throughout the area contaminating the air. Wrap all waste filters in air-tight plastic bags, then mark and dispose of according to current laws and regulations.

EXPERIENCING DIFFICULTIES. Keep in mind that CNC laser hazards are intensified in a confined space. If you are experiencing difficulties performing the intended operation, stop using the equipment, and contact the Occupational Safety and Health Administration (OSHA) at (800) 3216742, or online at www.osha.gov to find out how to design and maintain the best overall CNC laser toxic fume extraction system for your needs.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.

or equipment damage may occur if machine is not properly grounded and connected to power

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

For your own safety and protection of

Note: Circuit requirements in this manual apply to

a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

This machine can be converted to operate on a power supply circuit that has a verified ground and meets the requirements listed below. (Refer to Voltage Conversion instructions for details.)

Improper connection of the equipment-grounding wire can result in a risk of electric shock. The wire with green insulation (with or without yellow stripes) is the equipment-grounding wire. If repair or replacement of the power cord or plug is necessary, do not connect the equipment-grounding wire to a live (current carrying) terminal.

Check with a qualified electrician or service personnel if you do not understand these grounding requirements, or if you are in doubt about whether the tool is properly grounded. If you ever notice that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with a new one.

We do not recommend using an extension cord with this machine. cord, only use it if absolutely necessary and only on a temporary basis.

Extension cords cause voltage drop, which can damage electrical components and shorten motor life. Voltage drop increases as the extension cord size gets longer and the gauge size gets smaller (higher gauge numbers indicate smaller sizes).

Any extension cord used with this machine must be in good condition and contain a ground wire and matching plug/receptacle. Additionally, it must meet the following size requirements:

Grounding Requirements

This machine MUST be grounded. In the event of certain malfunctions or breakdowns, grounding reduces the risk of electric shock by providing a path of least resistance for electric current.

For 110V operation: This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug (see following figure). The plug must only be inserted into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances.

For 220V operation: The plug specified under “ page has a grounding prong that must be attached to the equipment-grounding wire on the included power cord.

Ducting System

Overview

This fume extractor is designed exclusively to extract and filter fumes and particulate generated during laser cutting processes. DO NOT use this fume extractor to collect wood dust. Due to potential fire risk, DO NOT use this fume extractor to collect metal chips.

For best performance, place this fume extractor as close to the laser system as possible and install blast gates at the beginning of ducting lines. Only open one line at a time to focus maximum suction at the machine where fumes are being extracted.

Grizzly offers a complete line of ducting and accessories for setting up your fume extraction ductwork (see Page 26)

Whatever system design you choose, always make sure to position ducting and extractor away from any open flames (including pilot lights); otherwise you risk an explosion if material is dispersed into the air.

Always guard against static electrical build up by grounding all collection lines.

There are a number of options when it comes to metal duct, but duct that is specially manufactured for extraction of laser fumes and particulate is the best choice. When selecting your metal duct, choose high-quality metal duct with smoothwelded internal seams that will minimize airflow resistance. This type of duct usually connects to other ducts or elbows with a simple, self-sealing clamp, is very quick and easy to assemble, and can be readily dismantled and re-installed. This is especially important if you ever need to change things around in your shop or add more machines.

Duct Material

For best results, use only smooth-wall, sheetmetal ducting or flexible metal ducting to connect each machine.

For further guidance on duct material, consult

NFPA 91: Standard for Exhaust Systems for Air Conveying of Vapors, Gases, and Particulate Solids from The National Fire Protection Agency.

Metal Ducting

Advantages of metal ducting is its conductivity and that it does not contribute to static electrical charge build-up. However, static charges are still produced when particles strike other dust particles as they move through the duct. Since metal duct is a conductor, it can be grounded quite easily to dissipate any static electrical charges. Replace any plastic exhaust ports with sheet-metal equivalents, or bond sheet metal ducting to metal frame of machine with grounding wire.

Figure 27. Examples of metal duct and

components.

Avoid inferior metal duct that requires you to cut it to length and snap it together. This type of duct is time-consuming to install because it requires you to seal all the seams with silicone and screw the components on the ends with sheet-metal screws. Another disadvantage is the rough internal seams and crimped ends that unavoidably increase static pressure loss.

-22-

Model G0953 (Mfd. Since 8/22)

Page 25

Flexible Duct

Flexible hose is generally used for short runs and at rigid duct-to-machine connections. The superior choice here is metal flex hose that is designed to be flexible, yet be as smooth as possible inside to reduce static pressure loss. DO NOT use dryer vent hose because it tends to collapse.

Figure 28. Example of flexible metal duct.

System Grounding

To guard against static electrical buildup, we strongly recommend replacing any plastic exhaust ports on laser machines with metal equivalents.

If you absolutely must use any plastic duct or components, they must be completely grounded and bonded to the metal frame of a grounded machine by wrapping the flex hose with an external ground wire connected to both machines as shown in Figure 30. Ensure that each machine is continuously grounded to the grounding terminal in your electric service panel.

Ensure Required CFM at Machine

Since each machine produces a different amount of fumes, the requirements for the minimum amount of CFM to move the fumes is unique to the machine. Knowing this required CFM is important to gauging what size duct to use.

For best results when using the inlet adapter, we recommend installing blast gates to control airflow for each line near the inlet.

Refer to Figure 29 for a close estimation of the airflow each laser cutting machine requires. Machines that generate the most fumes should be placed as close as possible to the fume extractor.

Schedule

of dust allowed to become airborne, and prevent spread of dust onto hands or clothing. Dispose of all waste properly according to local regulations for material type.

For optimum performance from this machine, this maintenance schedule must be strictly followed.

Ongoing

To minimize your risk of injury and maintain proper machine operation, shut down the machine immediately if you ever observe any of the items below, and fix the problem before continuing operations:

• Loose mounting bolts.

• Damaged filters. Worn or damaged wires.

• Suction leaks.

• Any other unsafe condition.

•

Monthly Check

• Clean/vacuum dust buildup off machine body.

Cleaning/Replacing

Filters

Cleaning Filters

Always clean filters outdoors when possible! However, take special care to avoid contaminating the environment. When cleaning filters, always inspect for damage and replace filters if ANY damage or tears are found.

Initially clean all filters by carefully tapping cakedon dust into an enclosed container to minimize release of dust into the air, then follow the applicable instructions provided below for each filter type.

IMPORTANT: DO NOT use compressed air to clean filters—especially if indoors—as it will likely cause a large amount of fine dust to become airborne and could damage the filters.

Re-install the filters in the same sequence in which they were removed (refer to Pages 20–21). Examine each filter to determine if it is marked with a label indicating the direction of airflow. If so, the filter should be installed with the arrow pointing down (toward the floor).

Clean the filters when the operating pressure on the pressure gauge exceeds 4 inches of water (inAq). Replace the filters when the operating pressure exceeds 7 inches of water (inAq) and cleaning does not improve performance.
