SECTION 1: SAFETY For Your Own Safety, Read Instruction Manual Before Operating This Machine The purpose of safety symbols is to attract your attention to possible hazardous conditions. This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that safety messages by themselves do not eliminate danger and are not a substitute for proper accident prevention measures.
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.
Additional Safety for Metal Dust Collectors Long-term respiratory damage, metal toxicity, cancer, or birth defects can occur from improperly using, setting up, or servicing machine, and using this machine without wearing a respirator. Explosions or fire can result if machine is used to capture incorrect materials or if dust/waste material is exposed to an ignition source. To reduce these risks, operator and bystanders MUST completely heed the warnings below. USE FOR INTENDED PURPOSE.
SECTION 2: POWER SUPPLY Availability 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.
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. 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.
SECTION 3: SETUP Needed for Setup This machine presents serious injury hazards to untrained users. Read through this entire manual to become familiar with the controls and operations before starting the machine! Wear safety glasses during the entire setup process! HEAVY LIFT! Straining or crushing injury may occur from improperly lifting machine or some of its parts. To reduce this risk, get help from other people and use a forklift (or other lifting equipment) rated for weight of this machine.
Inventory The following is a list of items shipped with your machine. Before beginning setup, lay these items out and inventory them. Hardware (Figure 3) Qty 5 1 I.

Site Considerations Weight Load Physical Environment Refer to the Machine Data Sheet for the weight of your machine. Make sure that the surface upon which the machine is placed will bear the weight of the machine, additional equipment that may be installed on the machine, and the heaviest workpiece that will be used. Additionally, consider the weight of the operator and any dynamic loading that may occur when operating the machine.
Assembly 2. Attach dust port to side of dust collector with (4) 5 ⁄ 16"-18 x 1⁄ 2" button head cap screws (see Figure 6). The machine must be fully assembled before it can be operated. Before beginning the assembly process, refer to Needed for Setup and gather all listed items. To ensure the assembly process goes smoothly, first clean any parts that are covered or coated in heavy-duty rust preventative (if applicable). x4 Note: Do not destroy packaging until after the Test Run.
4. Open access door. Remove protective wrap from collection drawer, and insert collection drawer where shown in Figure 8. Close and latch access door. 6. Install air filters in same sequence shown in Figure 10. Pleated Micro Filter Access Door Active Carbon Filter Stainless Mesh Filter Collection Drawer Filter Door Filter Door Figure 8. Collection drawer installed in dust collector. 5. Open filter door and verify dust tray is installed, as shown in Figure 9. Dust Tray Figure 10.
Ducting System Overview This dust collector is designed exclusively to collect dry metal, chips, and swarf. DO NOT use this dust collector to collect wood dust or metal chips containing cutting fluid or coolant. Due to fire or explosion risk, DO NOT use this machine to collect combustible or explosive metals, magnesium, niobium, tantalum, titanium, zirconium, hafnium, combustible liquids or fuels, gasoline, or oil- or solvent-based paints.
Flexible Duct System Grounding 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. To guard against static electrical buildup, we strongly recommend replacing any plastic dust ports on dust-producing machines with metal equivalents. Figure 12.
Test Run Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning correctly. To test run machine: 1. Clear all setup tools away from machine. 2. Connect machine to power supply. 3. Remove disabling pin from paddle switch, as shown in Figure 15. 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.
SECTION 4: OPERATIONS Operation To reduce your risk of serious injury, read this entire manual BEFORE using machine. This metal dust collector draws metal dust into a collection drawer and discharges air through a 3-stage air-filter system. Metal dust is collected in a primary 1.0-cubic-foot drawer that slides into the main compartment behind the access door, as shown in Figure 16. A secondary dust tray in the air filter compartment holds 0.23 cubic feet of material (see Figure 16, inset).
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.

If you work around dust every day, a half-mask respirator can be a lifesaver. Also compatible with safety glasses! H3635 Figure 25. Metal blast gates.
SECTION 6: MAINTENANCE Schedule For optimum performance from this machine, this maintenance schedule must be strictly followed. Ongoing To maintain a low risk of injury and proper machine operation, if you ever observe any of the items below, shut down the machine immediately and fix the problem before continuing operations: • • • • • Loose mounting bolts. Check/empty dust collection drawer/tray. Check/replace filters. Worn or damaged wires. Any other unsafe condition.
Cleaning Impeller 4. Remove motor/impeller assembly and carefully set it on capacitor covers (see Figure 32). The impeller normally requires no maintenance, but the blades can accumulate metal dust that can adversely affect impeller balance. Removing the motor/impeller assembly allows cleaning and inspection of the impeller blades. Tools Needed Qty Open-End Wrench 10 x 12mm........................... 1 Soft Bristle Brush...............................................
Cleaning/Replacing Filters The 5-Micron active carbon and 1-Micron pleated micro filters need regular cleaning. Replace every 300 hours or when airflow performance becomes noticeably reduced despite cleaning. Replacing Filters 1. DISCONNECT MACHINE FROM POWER! 2. Wear NIOSH-approved respirator, ANSIapproved goggles, and protective gloves while handling filters. 3. Unlatch filter door and open approximately 30 degrees. 4. Open (2) retaining clips on door and remove filters (see Figure 33).
