Since 1/13) SECTION 2: POWER SUPPLY Availability Circuit Requirements for 220V 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 electrican or qualified service personnel in accordance with all applicable codes and standards. This machine is prewired to operate on a 220V power supply circuit that has a verified ground and meets the following requirements: Electrocution, fire, or equipment damage may occur if machine is not correctly grounded and connected to the power supply. Full-Load Current Rating 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. Full-Load Current Rating at 220V..... 9.4 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 the full-load rating. Nominal Voltage.........................................220V Cycle...........................................................60 Hz Phase..................................................... 1-Phase Power Supply Circuit.......................... 15 Amps Plug/Receptacle.............................. NEMA 6-15 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: The circuit requirements listed in this manual apply to a dedicated circuit—where only one machine will be running at a time. If this machine will be connected to a shared circuit where multiple machines will be running at the same time, consult a qualified electrician to ensure that the circuit is properly sized for safe operation. 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 requirements in the following section. Model G0755 (Mfg. Since 1/13) -9- Grounding Instructions 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. The power cord and plug specified under “Circuit Requirements for 220V” on the previous page has an equipment-grounding wire and a grounding prong. 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 (see figure below). GROUNDED 6-15 RECEPTACLE Current Carrying Prongs 6-15 PLUG Grounding Prong Serious injury could occur if you connect the machine to power before completing the setup process. DO NOT connect to power until instructed later in this manual. 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 Figure 1. Typical 6-15 plug and receptacle. 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. Serious injury could occur if you connect the machine to power before completing the setup process. DO NOT connect to power until instructed later in this manual. Extension cords cause voltage drop, which may 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 contain a ground wire, match the required plug and receptacle, and meet the following requirements: Minimum Gauge Size............................14 AWG Maximum Length (Shorter is Better).......50 ft. No adapter should be used with the required plug. If the plug does not fit the available receptacle, or the machine must be reconnected for use on a different type of circuit, the reconnection must be made by a qualified electrician and comply with all local codes and ordinances. -10- Model G0755 (Mfg.

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 fork lift (or other lifting equipment) rated for weight of this machine. Power lifting equipment, steel rods (refer to Page 11), and at least two other people are required to lift and place the mill. Steel Rods Figure 5. LIfting setup. To move your machine into position: 1. Remove outside crating material from shipping crate, but leave machine bolted to pallet (for now). 2. Evenly position forklift forks under steel rods on each side of cabinet. Note: Before next step, make sure all locks are tight to avoid sudden shifts which could unbalance machine. Move machine next to its intended installation location, then unbolt it from pallet. 3. To help balance machine during moving, position table as close to column as possible, and adjust headstock to its lowest position. -14- 5. 6. With help of additional people to steady load, slowly lift machine, remove pallet, then lower machine into position. Model G0755 (Mfg. Since 1/13) Anchoring to Floor Assembly Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid. Except for the handwheel handles, the mill/drill was fully assembled at the factory. if the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may require that it be anchored to the floor. Use a slotted screwdriver to attach the handwheel handles, as shown in Figure 7. if not required by any local codes, fastening the machine to the floor is an optional step. if you choose not to do this with your machine, we recommend placing it on machine mounts, as these provide an easy method for leveling and they have vibration-absorbing pads. Anchoring to Concrete Floors Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. however, anytime local codes apply, you Must follow the anchoring methodology specified by the code.

Popular method for anchoring machinery to a concrete floor. Model G0755 (Mfg. Since 1/13) -15- Joining Drill Chuck & Arbor Lubricating Mill/Drill An arbor is included for the drill chuck that comes with this machine. The following procedure describes how to install the arbor in the chuck. GEARBOX MUST BE FILLED WITH OIL! After the arbor is installed in the drill chuck, it is very difficult to separate the assembly. If you would like to use a different chuck in the future, we recommend obtaining a new arbor. Important: DO NOT install the drill chuck and arbor assembly into the spindle until AFTER the test run. To join the drill chuck and arbor: 1. Use acetone or lacquer thinner to clean drill chuck and arbor mating surfaces, especially the bore. 2. Retract chuck jaws completely into chuck. 3. Insert small end of arbor into chuck. 4. Hold assembly by the arbor and tap chuck onto a block of wood with medium force, as illustrated in Figure 8. OIL MAY NOT BE SHIPPED WITH MACHINE! Refer to Lubrication Section for Correct Oil Type. The headstock oil reservoir must be properly filled with oil before the mill/drill can be operated for the first time. Damage caused by running the mill/drill without the proper amount of oil in the reservoir will not be covered under warranty. Refer to the Lubrication section, beginning on Page 30, for details on how to check and add oil. Figure 8. Tapping drill chuck/arbor on block of wood. 5. -16- Attempt to separate drill chuck and arbor by hand—if they separate, repeat Steps 3–4. Model G0755 (Mfg. Since 1/13) Test Run 4.

Since 1/13) -17- Spindle Break-In Before placing operationql loads on the spindle, complete this break-in procedure to fully distribute lubrication throughout the bearings and ensure trouble-free performance. Failure to complete the spindle break-in process may lead to premature failure of the bearings—this will not be covered under warranty. To perform the spindle break-in procedure: 1. Make sure the spindle is completely stopped, then set spindle speed to 90 RPM (refer to Page 26 for detailed instructions). Inspections & Adjustments The following list of adjustments were performed at the factory before the machine was shipped: • Gib Adjustments...............................Page 37 • Leadscrew Backlash Adjustments......................................Page 37 • Return Spring Tension..................... Page 40 Be aware that machine components can shift during the shipping process. Pay careful attention to these adjustments during operation of the machine. If you find that the adjustments are not set according to the procedures in this manual or your personal preferences, re-adjust them. Do not leave the mill/drill unattended during the Spindle Break-In procedure. If your attention is needed elsewhere during this procedure, stop the mill/drill and restart the procedure later from the beginning. 2. Run machine for a minimum of 10 minutes. 3. Repeat Step 2 for each spindle speed, working to progressively higher speeds. Note: If the machine is new, we recommend changing the headstock oil while it is still warm and any particles from the manufacturing process are still in suspension (refer to Page 31 in the Lubrication subsection for detailed instructions). The spindle break-in is now complete! -18- Model G0755 (Mfg. Since 1/13) SECTION 4: OPERATIONS Operation Overview The purpose of this overview is to provide the novice machine operator with a basic understanding of how the machine is used during operation, so the machine controls/components discussed later in this manual are easier to understand. Due to the generic nature of this overview, it is not intended to be an instructional guide. To learn more about specific operations, read this entire manual and seek additional training from experienced machine operators, and do additional research outside of this manual by reading "howto" books, trade magazines, or websites. To complete a typical operation, the operator does the following: 1. Examines workpiece to make sure it is suitable for cutting. 2. Puts on protective gear. 3. Securely clamps workpiece to table. 4. With machine disconnected from power, installs correct cutting tool. 5. Adjusts headstock height above table. 6. Without the machine running, checks range of table or spindle movement to make sure setup is safe and correct for operation. 7. Selects correct spindle speed. To reduce your risk of serious injury, read this entire manual bEFORE using machine. To reduce risk of eye or face injury from flying chips, always wear approved safety glasses and a face shield when operating this machine. 8. Connects machine to power and turns it ON. 9. Uses downfeed controls or table controls to perform cutting operation. 10. Turns machine OFF and waits for spindle to completely stop before removing workpiece. 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. Model G0755 (Mfg.

Hold onto tool holder with one hand and fully unthread drawbar with the other hand. Spindle Speed Using the correct spindle speed is important for safe and satisfactory results, as well as maximizing tool life. To set the spindle speed for your operation, you will need to: 1) Determine the best spindle speed for the cutting task, and 2) configure the spindle speed levers to produce the required spindle speed. Determining Spindle Speed Many variables affect the optimum spindle speed to use for any given operation, but the two most important are the recommended cutting speed for the workpiece material and the diameter of the cutting tool, as noted in the formula shown in Figure 26. *Recommended Cutting Speed (FPM) x 12 Tool Dia. (in inches) x 3.14 Spindle = Speed (RPM) *Double if using carbide cutting tool Figure 26. Spindle speed formula for mill/drills. Cutting speed, typically defined in feet per minute (FPM), is the speed at which the edge of a tool moves across the material surface. A recommended cutting speed is an ideal speed for cutting a type of material in order to produce the desired finish and optimize tool life. The books Machinery’s Handbook or Machine Shop Practice, and some internet sites, provide excellent recommendations for which cutting speeds to use when calculating the spindle speed. These sources also provide a wealth of additional information about the variables that affect cutting speed and they are a good educational resource. Also, there are a large number of easy-to-use spindle speed calculators that can be found on the internet. These sources will help you take into account the applicable variables in order to determine the best spindle speed for the operation. Model G0755 (Mfg. Since 1/13) -25- Setting Spindle Speed The chart below explains how to position the spindle range and speed levers to set the desired spindle speed. Spindle Speed Range Lever Speed Lever 90 RPM L 1 210 RPM L 2 345 RPM L 3 670 RPM H 1 1180 RPM H 2 1970 RPM H 3 Change spindle speed ONLY when the spindle is completely stopped. Otherwise, machine damage could occur. With the spindle completely stopped, position the spindle range and speed levers (see Figure 27) to set the spindle speed. Note: If the levers will not move to the desired position, rotate the spindle by hand while applying pressure on the lever. When the gear teeth align, the lever will move into place.

Schedule For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section. Daily Check: Loose mounting bolts. • • Damaged tooling. • Worn or damaged wires. • Clean debris and built up grime off of machine. • Any other unsafe condition. Every 8 Hours of Operation: • Check/add headstock oil (Page 31). • Lubricate ball oilers (Page 32). • Lubricate table/column ways and quill (Page 32). Every 40 Hours of Operation: • Lubricate table leadscrews (Page 33). Every 90 Days of Operation: • Lubricate quill rack and pinion (Page 33). • Lubricate Z-axis leadscrew (Page 34). Annually: • Change headstock oil (Page 31). Cleaning and Protecting Metal chips left on the machine will invite oxidation and a gummy residue build-up around the moving parts. Use a brush and shop vacuum to remove chips and debris from the working surfaces of the mill/drill. Never blow off the mill/drill with compressed air, as this will force metal chips deep into the mechanisms and may cause injury to yourself or bystanders. Remove any rust build-up from unpainted cast iron surfaces of your mill/drill and treat with a nonstaining lubricant after cleaning. Keep unpainted cast iron surfaces rust-free with regular applications of ISO 68 way oil (see Page 27 for offerings from Grizzly). Lubrication An essential part of lubrication is cleaning the components before lubricating them. This step is critical because grime and chips build up on lubricated components, which makes them hard to move. Simply adding more lubricant will not result in smooth moving parts. Clean all exterior components in this section with mineral spirits, shop rags, and brushes before lubricating. DISCONNECT MACHINE FROM POWER BEFORE PERFORMING LUBRICATION. NOTICE Follow reasonable lubrication practices as outlined in this manual. Failure to do so could lead to premature failure of your machine and will void the warranty. -30- Model G0755 (Mfg.

Sharpen cutting tool or select one that better suits the operation. 3. Check for proper cutting rotation for cutting tool. 4. Properly clamp workpiece on table or in vise. 5. Fully retract spindle and lower headstock. This increases rigidity. 1. Tram the spindle (Page 38). Model G0755 (Mfg. Since 1/13) Adjusting Gibs Gibs are tapered lengths of metal that are sandwiched between two moving surfaces. Gibs control the gap between these surfaces and how they slide past one another. Correctly adjusting the gibs is critical to producing good results. Correctly positioning gibs is a matter of trial and error and patience. Tight gibs make table movement more accurate but stiff. Loose gibs make table movement sloppy but easier to do. The goal of gib adjustment is to remove unnecessary sloppiness without causing the ways to bind. Many experienced machinists adjust the gibs just to the point where they can feel a slight drag in table movement. Screws on each end of the gib allow gib adjustment to increase or decrease the friction between the sliding surfaces. DISCONNECT MACHINE FROM BEFORE ADJUSTING THE GIBS! POWER Make sure all table locks are loose. Then, loosen one gib adjustment screw (see Figure 53) and tighten the opposing screw the same amount to move the gib, while at the same time rotating the handwheel to move the table until you feel a slight drag in that path of movement. Y-Axis Gib Screw (1 of 2) X-Axis Gib Screw (1 of 2) Adjusting Leadscrew Backlash Leadscrew backlash is the amount of freeplay movement in the leadscrew (when the leadscrew moves but the table does not) after changing the direction of rotation. Leadscrews must have a certain amount of backlash to rotate easily, but over time, it increases with wear. Generally, 0.003"–0.006" leadscrew backlash is acceptable to ensure smooth movement and reduce the risk of premature thread wear. The X- and Y-axis leadscrew backlash is adjusted using a long 4mm hex wrench to tighten/ loosen the cap screw on the leadscrew nut. This adjusts the force the leadscrew nut exerts on the leadscrew threads. The X-axis leadscrew nut shown in Figure 54 is accessed from underneath the left side of the table. The Y-axis leadscrew nut is similar and is accessed from inside the cabinet underneath the machine base. X-Axis Leadscrew Nut Cap Screw Figure 54. Location of X-axis leadscrew nut for adjusting backlash. Figure 53. Location of table gib screws. Model G0755 (Mfg. Since 1/13) -37- Tramming Spindle When your operation requires that the spindle axis be precisely perpendicular to the table, you must tram the spindle with the table. Simply adjusting the headstock tilt to the 90° mark on the tilt scale will not be precise enough for highly accurate results. This procedure involves mounting a dial indicator to the quill or spindle, rotating it around the table, and adjusting the head position so that the spindle axis is 90° to the table X-axis, as illustrated in Figure 55. Spindle Table Z-Axis Tools Needed Qty Dial Indicator (with at least 0.0005" resolution).. 1 Indicator Holder (mounted on quill/spindle)........ 1 Precision Parallel Block (1-2-3 Blocks)............... 1 Note: A precision-ground plate can be substituted for the parallel block. The farther the indicator point can be placed from the spindle axis, the more accurate the alignment measurements will be. To tram the spindle with the table: 1. DISCONNECT MACHINE FROM POWER! 2. Prepare machine by performing the following tasks: — Stone table to remove all nicks and burrs, then clean off all debris. Verify table is clean by running your hand over the top of it. — Position table for the operation you intend to perform after tramming—preferably centered with saddle. 90 º X-Axis — Tighten any table locks that should be tight during intended milling operation. Figure 55. Spindle centerline properly trammed to the table. Note: Keep in mind that the top surface of your workpiece will not likely be exactly parallel with the table top. Depending on your operation, you may choose to tram the spindle to the top surface of the workpiece after it is mounted instead of tramming to the table. 3. Place parallel block underneath spindle. 4. Install indicator holder into spindle or onto quill, then mount indicator onto it so that the point is as parallel to the block as possible (see the illustration in Figure 56 for an example). Indicator Holder Spindle Dial Indicator Parallel Block Table Figure 56. Dial indicator mounted. -38- Model G0755 (Mfg. Since 1/13) 5. Place the parallel block directly under spindle and indicator across length of table, as illustrated in Figure 57. Note: If you must re-position quill to accommodate the above step, then review tasks in Step 2 to make sure mill is properly prepared for tramming. Table (Top View) Parallel Block Replacing Power Feed Carbon Brushes The X-axis power feed motor has a carbon brushes that will wear with normal use. There is one on the top of the power feed (see Figure 58) and one on the bottom. Cap Indicator Carbon Brush Spindle Figure 57. Setup for the X-axis adjustment. Note: Generally, the goal is to get the difference of the indicator readings between ends of the parallel bar down to 0.0005". However, the acceptable variance will depend on the requirements for your operation. Brush Hole Figure 58. Carbon brush removed from power feed. 6. Rotate spindle by hand so that the indicator point rests on one end of parallel block, as illustrated in Figure 57, then zero dial. If, over time, the power feed starts to seem sluggish or will not operate, check the carbon brushes. If they are less than 3 ⁄ 16" in length, replace them with new ones (Part No. P0755501-6). 7. Rotate spindle so that the indicator point rests in the same manner on other end of block, then read dial. Note: For proper performance, replace both carbon brushes at the same time. — If indicator dial still reads zero or is within the acceptable variance, continue on with Step 8. Use a flat screwdriver to unthread (turn counterclockwise) the cap covering the carbon brush, replace the brush assembly, then secure it with the cap. — If indicator dial has moved from zero beyond the acceptable variance, you will need to compensate for that amount by tilting head left or right. Repeat Steps 6–7 until you are satisfied with spindle axis alignment along table X-axis. Tip: Keep one of the tilting hex nuts snug so that the head does not move loosely while you adjust it in small amounts. 8. Re-tighten tilting hex nuts. Model G0755 (Mfg. Since 1/13) -39- Tightening Return Spring Tension The return spring moves the spindle back up when the coarse downfeed handles are released. The tension of this spring was adjusted at the factory, but it may need to be tightened during the life of the mill/drill. Important: Do not perform this procedure unless it is absolutely necessary. During this procedure, you will loosen the spring cover thumb screw (See Figure 59) just enough to pull the cover back to clear the roll pin, then rotate the cover counterclockwise to fit the roll pin in the next slot. Roll Pin 1. DISCONNECT MACHINE FROM POWER! 2. Wipe off any oil on spring cover so it does not slip when you hold it during adjustments. 3. Mark slot on cover that engages the roll pin at the top—this is the factory setting. 4. Put on heavy leather gloves to protect your hands from lacerations if spring uncoils during next step. Note: Keep a good grip on spring cover during next step. Letting go of cover when roll pin is not engaged will cause spring to rapidly uncoil. 5. While holding spring cover against side of headstock so the spring will not unwind, loosen thumb screw approximately 1⁄4". 6. Pull cover out to disengage it with roll pin, then rotate it counterclockwise to engage roll pin in the next slot in cover. Cover Thumb Screw To adjust the return spring tension: Cover Slots 7. Re-tighten thumb screw to secure setting. Figure 59. Return spring components. If the return spring should come loose from the spring cap and rapidly unwind, laceration or impact injuries could occur. Always wear heavy leather gloves and safety glasses when adjusting the return spring tension. -40- Model G0755 (Mfg.
