When machine is not being used, disconnect power, remove switch keys, or lock-out machine to prevent unauthorized use—especially around children. Make your workshop kid proof! DANGEROUS ENVIRONMENTS. Do not use machinery in areas that are wet, cluttered, or have poor lighting. Operating machinery in these areas greatly increases the risk of accidents and injury. MENTAL ALERTNESS REQUIRED. Full mental alertness is required for safe operation of machinery. Never operate under the influence of drugs or alcohol, when tired, or when distracted.
ELECTRICAL EQUIPMENT INJURY RISKS.
You can be shocked, burned, or killed by touching live electrical components or improperly grounded machinery. To reduce this risk, only allow qualified service personnel to do electrical installation or repair work, and always disconnect power before accessing or exposing electrical equipment.
DISCONNECT POWER FIRST. Always disconnect machine from power supply BEFORE making adjustments, changing tooling, or servicing machine. This prevents an injury risk from unintended startup or contact with live electrical components.
EYE PROTECTION. Always wear ANSI-approved safety glasses or a face shield when operating or observing machinery to reduce the risk of eye injury or blindness from flying particles. Everyday eyeglasses are NOT approved safety glasses.
WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts. HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.
HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death! AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.
FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.
NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked. USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for rec- ommended accessories. Using improper accessories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.
MAINTAIN WITH CARE. Follow all maintenance instructions and lubrication schedules to keep machine in good working condition. A machine that is improperly maintained could malfunction, leading to serious personal injury or death. DAMAGED PARTS.

If at any time you experience difficulties performing the intended operation, stop using the machine! Contact our Technical upport at 570-546-9663.

Additional Safety for Dust Collectors

Long-term respiratory damage can occur from using dust collectors without proper use of a respirator. Fire or explosions can result in smoke inhalation, serious burns, or death—if machine is used to collect incorrect materials, is operated near potential explosion sources, or ducting is improperly grounded. Entanglement, amputation, or death can occur if hair, clothing, or fingers are pulled into the inlet. To reduce the risk of these hazards, operator and bystanders MUST completely heed the hazards and warnings below.
INTENDED USE. Collecting the wrong materials can result in serious inhalation hazards, fire, explosions, or machine damage. This machine is ONLY designed to collect wood dust and chips from woodworking machines. DO NOT use it to collect silica, polyurethane, toxic fumes, metal dust or shavings, lead paint, drywall, asbestos, biohaz- ards, explosive dusts, flammable or combustible liquids or fumes, nor burning or smoking material.
WEAR A RESPIRATOR. Fine dust that is too small to be caught in filter will be blown into ambient air. Always wear a NIOSH-approved respirator during operation and for a short time after to reduce your risk of permanent respiratory damage. Never collect dust from any hazardous material.
IMPELLER HAZARDS. To reduce risk of entanglement or contact with impeller, DO NOT place hands, hair, clothing, or tools in or near open dust collection inlet during operation, and keep small animals and children away. The powerful suction could easily pull them into impeller.
HAZARDOUS DUST. Dust exposure created while using machinery may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material, and always wear a NIOSH-approved respirator.
EMPTYING DUST. When emptying bag or drum, ear respirator and safety glasses. Empty dust away from ignition sources and into approved ontainer.
OPERAT I NG LOCAT I ON. To reduce respiratory exposure to fine dust, locate permanently installed dust collectors away from working area or in another room.
DO NOT place dust collector where it can be exposed to rain or moisture, which creates a shock hazard and will reduce life of machine.
POWER DISCONNECT. Turn machine OFF, disconnect from power supply, and allow impeller to completely stop before leaving machine unattended, or doing any maintenance or service.
REGULAR CLEANING. To reduce risk of start- ing a fire, regularly check/empty collection bags or drum to avoid buildup of fine dust, which can increase risk of fire. Regularly clean surrounding area where machine is operated—excessive dust buildup on overhead lights, heaters, electrical panels, or other  heat sources will increase risk of fire.
SUSPENDED DUST PARTICLES. To reduce risk of death or injury caused by explosions or fires, DO NOT operate in areas where these risks are high, including spaces near pilot lights, open flames, or other ignition sources.
AVOIDING SPARKS. To reduce risk of fire, avoid collecting any metal objects or stones. These can possibly produce sparks when they strike impeller, which can smolder in wood dust for a long time before a fire is detected. If you accidentally cut into wood containing metal, immediately turn OFF dust collector, disconnect from power, and wait for impeller to stop. Then empty bag or drum into approved airtight metal container.
FIRE SUPPRESSION. Only operate dust collector in locations that contain fire suppression system or have fire extinguisher nearby.
STATIC ELECTRICITY. To reduce risk of fire or explosions caused by sparks from static electricity, ground all ducting using grounding wire.
DUST ALLERGIES. Dust from certain woods will cause an allergic reaction. Make sure you know what type of wood dust you will be exposed to in case of an allergic reaction.

SECTION 2: POWER SUPPLY

Availability
Before installing the machine, consider the availability and proximity of the required power supply circuit. f 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.
Electrocution, fire, shockor equipment damagemay occur if machine is not properly groundedand connected to powesupply.
Full-Load Current Rating
The full-load current rating is the amperage a1 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.
Full-Load Current Rating at 110V…….. 8 Amps
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 he 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.
Serious injury could occur if you connect machine to power before completing setup process. DO NOT connect to power until instructed later in this manual.
110V Circuit Requirements
This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:
Nominal Voltage ……………….. 110V, 115V, 120V
Cycle ………………………………………………….60 Hz
Phase ……………………………………. Single-Phase
Power Supply Circuit ……………………. 15 Amps
Plug/Receptacle ……………………….. NEMA 5-15
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.)
For your own safety and protection of property, consult an electrician if you are unsure about wiring practices or electrical codes in your area.
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 ervice personnel to ensure circuit is properly sized for safe operation.
Grounding & Plug 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.
This machine is equipped with a power cord that has an equipment-grounding wire and a grounding plug. Only insert plug into a matching receptacle (outlet) that is properly installed and grounded in accordance with all local codes and ordinances. DO NOT modify the provided plug! SHOCK HAZARD!
Two-prong outlets do not meet the grounding requirements for this machine. Do not modify or use an adapter on the plug provided—if it will not fit the outlet, have a qualified electrician install the proper outlet with a verified ground.
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.
Extension Cords
We do not recommend using an extension cord with this machine. If you must use an extension 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:
Minimum Gauge Size ………………………16 AWG
Maximum Length (Shorter is Better)…….50 ft.

Collection System

Material Selection
You have many choices regarding dust collection ducting, but flexible hose is the most common for this size of machine. However, be aware that there is a fire or explosion hazard if plastic duct material is used for dust collection without being grounded against tatic electrical charge build-up.
Flexible rubber hose, polyethylene, plastic flexhose and other flexible ribbed hose is generally used for short runs. There are many different types of flex hose on the market today. These are manufactured from materials such as polyethylene, PVC, cloth hose dipped in rubber and even metal, including steel and aluminum.
If using flex-hose, you should choose one of the many types that are designed specifically for the movement of solid particles, such as wood dust. However, the cost of specifically designed flexible duct can vary greatly. Grizzly offers polyethylene and steel flex hose.
Always guard against static electrical build up by grounding all dust collection lines.
Duct Grounding
Plastic flex-hose is an insulator, and dust particles moving against the walls of the hose creates a static electrical build up. This charge will build until it discharges to a ground. If a grounding medium is not available to prevent static electrical build up, the electrical charge will arc to the nearest grounded source. This electrical discharge may cause an explosion and subsequent fire inside the system.
To protect against static electrical build up inside a non-conducting duct, a bare copper wire should be placed inside the duct along its length and grounded to the dust collector. You must also confirm that the dust collector is continuously grounded through the electrical circuit to the electric service panel.
Be sure that you extend the bare copper wire down all branches of the system. Do not forget to connect the wires to each other with wire nuts when two branches meet at a “Y” or “T” connection.
Ensure that the entire system is grounded. If using plastic blast gates to direct air flow, the grounding wire must be jumped (see the figure below) around the blast gate without interruption to the grounding system. Figure 17. Ground jumper wire when using plastic blast gates or elbows and metal duct.
We also recommend wrapping the outside of all plastic ducts with bare copper wire to ground the outside of the system against static electrical buildup. Wire connections at Y’s and T’s should be made with wire nuts.
Attach the bare ground wire to each stationary woodworking machine and attach to the dust collector frame with a ground screw as shown in the figure below. Ensure that each machine is continuously grounded to the grounding terminal in your electric service panel. Dust Collection
Since each machine produces a different amount of sawdust, the requirements for the minimum amount of CFM to move that sawdust is unique to the machine (for example, a planer produces more sawdust than a table saw). Knowing this required CFM is important to gauging which size of duct to use.
Refer to the figure below for a close estimation of the airflow each machine requires. Keep in mind that machines that generate the most sawdust should be placed closest to the dust collector.
If the machine has multiple dust ports, the total CFM required is the sum of all ports.

Figure 19. Approximate required airflow for machines, based on dust port size.
If the machine does not have a built-in dust port, use the following table to determine which size of dust port to install.

Figure 20. Dust port size and quantity peraverage machine.
To solve any other dust collection questions, Grizzly offers a guide book entitled Dust Collection Basics that will help you design your system.

Test Run

Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning correctly.
If you find an unusual problem during the test run, immediately stop the machine, disconnect it from power, and fix the problem BEFORE operating the machine again. The Troubleshooting table in the SERVICE section of this manual can help.
The Test Run consists of verifying the following: 1) The motor powers up and runs correctly, and 2) the safety disabling mechanism on the ON/OFF switch works correctly.
Serious injury or death can result from using this machine BEFORE understanding its controls and related safety information. DO NOT operate, or allow others to operate, machine until the information is understood.
DO NOT start machine until all preceding setup instructions have been performed. Operating an improperly set up machine may result in malfunction or unexpected results that can lead to serious injury, death, or machine/property damage.

To test run machine:

1. Clear all setup tools away from machine.

2.  Connect machine to dust collection system or cover inlet.
   IMPORTANT: DO NOT operate dust collector without first connecting it to dust collection system or covering inlet. Otherwise, lack of airflow resistance will cause motor to operate at full amperage load, which could trip your circuit breaker or blow fuse.

3.  Connect machine to power.

4. 5Use ON/OFF switch to turn machine ON (see Figure 22), verify motor operation, and then turn machine OFF.
   Motor should run smoothly and without unusual problems or noises.

5. Remove switch disabling key from ON/OFF switch, as shown in Figure 23.

6.  Try to start machine with ON/OFF switch. Machine should not start.
   — If machine does not start, switch disabling feature is working correctly.
   — If machine does start, immediately stop machine. Switch disabling feature is not working correctly. This safety feature must work properly before proceeding with regular operations. Call Tech Support for help.

SECTION 4: OPERATIONS

To reduce your risk of serious injury, read this entire manual BEFORE using machine.
To reduce risk of eye injury from flying chips or lung damage from breathing dust, always wear safety glasses and a respirator when operating this machine. DO NOT put hands or small objects near inlet opening during operation. Objects sucked into inlet will meet with impeller blade. Failure to heed this warning could result in personal injury or property damage.
Never place dust collector in room with open flames or pilot lights. There is a risk of explosion if too much fine dust is dispersed into air with open flame present.
Notice If you are not experienced with this type of machine, WE STRONGLY RECOMMEND that you seek additional training outside of this manual. Read books/magazines or get formal training before beginning any projects. Regardless of the content in this
section, Grizzly Industrial will not be held liable for accidents caused by lack of training.
General
Keep in mind that the dust collector is intended for single machine use and is not designed to draw dust through long ducting runs and multiple ports simultaneously.
To complete a typical operation, the operator does the following:

1. Positions machine near dust collector and uses appropriate ducting to connect machine to dust collector.
2.  Connects ducting ground.
3.  Turns woodworking machine, then dust col lector ON.
4.  Performs woodworking operation.
5.  Turns woodworking machine, then dust col lector OFF.

Tips for Optimum Performance

•  Keep duct between dust collector and machine as short as possible. We do not recommend using more than 10′ of ducting. The simpler the system, the more efficient and less costly it will be.
• Ridges inside flexible hose greatly increase static pressure loss, which reduces suction performance.
•  Keep ducting directional changes to a minimum. The more curved fittings you use, the greater the loss of suction at dust-producing machine.
•  Gradual directional changes are more efficient than sudden directional changes (i.e. use 45° elbows in place of 90° elbows whenever possible).

SECTION 5: ACCESSORIES

Installing unapproved accessories may cause machine to malfunction, resulting in serious personal injury or machine damage. To reduce this risk, only install accessories recommended for this machine by Grizzly.

SECTION 6: MAINTENANCE

To reduce risk of shock or accidental startup, always disconnect machine from power before adjustments, maintenance, or service.
Schedule
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.
• Worn switch
• Worn or damaged wires.
•  Full collection bag.
•  Any other unsafe condition.

Lubrication
Since all bearings are shielded and permanently lubricated, simply leave them alone until they need to be replaced. DO NOT lubricate them.
Machine Storage
When the dust collector is not in use, unplug the power cord from the power source. Place the cord away from potential damage sources, such as high traffic areas, sharp objects, heat sources, harsh chemicals, water, damp areas, etc.
Emptying/Replacing Bags
Empty or replace the collection bag when it is about ⁄2 full. Replace the filter bag on a regular basis to allow the machine to operate at a much higher level of efficiency. Always wear the appropriate respirator or dust mask and safety glasses during this process, as small dust particles can escape the bags, causing them to become airborne and easily inhaled. This microscopic airborne dust is unsafe to breathe and can serious health problems.
To reduce risk of eye injury from flying chips or lung damage from breathing dust, always wear safety glasses and a respirator when changing collection or filter bags. To empty/replace bags:

1. DISCONNECT MACHINE FROM POWER!
2.  Put on safety glasses and respirator.
3.  Release bag clamp securing bag, unhook bag from support rods, then remove bag from collector.
4. Empty bag or securely close top and safely dispose of it according to local and federal standards.
5.  Re-install bag or replace it with a new one.
