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 Lathes Serious injury or death can occur from getting entangled in, crushed between, or struck by rotating parts on a lathe! Unsecured tools or workpieces that fly loose from rotating objects can also strike nearby operators with deadly force. To minimize the risk of getting hurt or killed, anyone operating this machine MUST completely heed the hazards and warnings below. CLOTHING, JEWELRY & LONG HAIR. Tie back long hair, remove jewelry, and do not wear loose clothing or gloves.
Glossary of Terms The following is a list of common definitions, terms and phrases used throughout this manual as they relate to this lathe and metalworking in general. Become familiar with these terms for assembling, adjusting or operating this machine. Your safety is VERY important to us at Grizzly! Arbor: A machine shaft that supports a cutting tool. Backlash: Wear in a screw or gear mechanism that may result in slippage, vibration, and loss of tolerance.
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 & 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.
SECTION 3: SETUP Unpacking Needed for Setup This machine was carefully packaged for safe transport. When unpacking, separate all enclosed items from packaging materials and inspect them for shipping damage. If items are damaged, please call us immediately at (570) 546-9663. The following are needed to complete the setup process, but are not included with your machine.
Inventory The following is a list of items shipped with your machine. Before beginning setup, lay these items out and inventory them. If any non-proprietary parts are missing (e.g. a nut or a washer), we will gladly replace them; or for the sake of expediency, replacements can be obtained at your local hardware store. Installed Components (Figure 10) Qty. A. 5" Three-Jaw Chuck.................................... 1 B. Steady Rest................................................. 1 C. Follow Rest..............
Cleanup The unpainted surfaces of your machine are coated with a heavy-duty rust preventative that prevents corrosion during shipment and storage. This rust preventative works extremely well, but it will take a little time to clean. Be patient and do a thorough job cleaning your machine. The time you spend doing this now will give you a better appreciation for the proper care of your machine's unpainted surfaces.
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.
Lifting & Placing 5. Wrap the lifting straps around the bed and between the leadscrew and the bedway, as shown in Figure 14, to help prevent bending the leadscrew during lifting. 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.
Leveling & Mounting For accurate turning results and to prevent warping the cast iron bed and ways, the lathe bedways MUST be leveled from side-to-side and from front-to-back on both ends. Re-check the bedways 24 hours after installation, two weeks after that, and then annually to make sure they remain level. Mounting The chip pan and the base of the lathe have holes that allow the machine to be mounted to a workbench.
Assembly Power Connection With the exception of the handwheel handles, the lathe is shipped fully assembled. Before the machine can be connected to the power source, an electrical circuit and connection device must be prepared per the POWER SUPPLY section in this manual, and all previous setup instructions in this manual must be completed to ensure that the machine has been assembled and installed properly.
To test run your machine: 1. Half Nut Lever Make sure the spindle direction switch (see Figure 18) is turned to STOP, and press the emergency STOP button. Disengaged Emergency Stop Button Halfnut Lever ON Button Engaged Spindle Direction Switch Pointing to STOP Figure 18. Headstock and gearbox controls. 2.
Spindle Break-In Before subjecting the lathe to full loads, it is essential to complete the spindle break-in process. This will ensure the best results and maximum life of the precision components inside the lathe. The break-in procedure must be performed in succession with the Test Run procedure because many of the test run steps prepare the lathe controls for the break-in process.
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.
Chuck & Faceplate Mounting Installation & Removal Devices This lathe is equipped with a threaded spindle nose. With this type of spindle, a chuck or faceplate is screwed directly onto the spindle nose. Because chucks are heavy and often awkward to hold, some kind of support or protective device should be used during installation or removal. The weight and size of the chuck will determine the appropriate device to use (refer to the following figure for examples).
Chuck Installation 5. Insert the chuck wrenches as shown in Figure 22, and tighten the chuck until it is seated snug against the spindle shoulder. To ensure accurate work, it is extremely important to make sure the spindle nose and chuck mating surfaces are clean. Even a small amount of lint or debris can affect accuracy. The chuck is properly installed when it threads all the way onto the spindle nose (see Figure 21 below) and is seated against the spindle shoulder.
Chuck Removal Changing Jaw Set Tools Needed: Qty Chuck Wrenches................................................ 2 Hex Wrench 5mm............................................... 1 Tools Needed: Qty Chuck Wrench.................................................... 1 To remove the chuck: 1. DISCONNECT LATHE FROM POWER! 2. Use an appropriate device to protect the ways and support the chuck (refer to Installation & Removal Devices on Page 26). 3. Remove the cap screws and chuck locks (see Figure 24).
To change the jaw set: 1. DISCONNECT LATHE FROM POWER! 2. Place a piece of plywood over the bedways to protect them from potential damage. 3. Insert the chuck key and turn it counterclockwise to back the jaws out and remove them. 4. Use mineral spirits to clean the debris and grime from the jaws and chuck jaw guides. 5. Apply a thin coat of white lithium grease to the surfaces of the removed jaw set. Store in a safe place free from moisture and abrasives. 6.
4-Jaw Chuck 5. Refer to the Chuck Installation (see Page 27) and Chuck Removal (see Page 28) instructions to install or remove the 4-jaw chuck. The 4-jaw chuck features independently adjustable hardened steel jaws for holding non-concentric or off-center workpieces. Each jaw can be independently removed from the chuck body and reversed for a wide range of work holding versatility. Tighten each jaw in small increments.
Faceplate Refer to the Chuck Installation (see Page 27) and Chuck Removal (see Page 28) instructions to install or remove the faceplate. The faceplate included with your lathe can be used for a wide range of operations, including machining non-concentric workpieces, straight turning between centers, off-center turning, and boring. The tools needed for mounting a workpiece will vary depending on the type of setup you have.
Tailstock The tailstock (see Figure 33) is typically used to support long workpieces by means of a live or dead center (refer to Centers on Page 36). It can also be used to hold a drill or chuck to bore holes in the center of a part. Custom arbors and tapers can also be cut on your lathe by using the offset tailstock adjustment.
To install tooling in the tailstock: To offset the tailstock: 1. With the tailstock locked in place, unlock the quill, then use the handwheel to extend it approximately 1". 1. 2. Thoroughly clean and dry the tapered mating surfaces of the quill and the center, making sure that no lint or oil remains on the tapers. 3. With a firm and quick motion, insert the tool into the quill, as shown in Figure 35 on Page 32.
Aligning Tailstock to Spindle Centerline This is an essential adjustment that should be verified or performed each time the tailstock is used to turn concentric workpieces between centers or immediately after offsetting the tailstock when turning a taper. If the tailstock is not aligned with the spindle centerline when it is supposed to be, turning results will be inaccurate along the length of the workpiece.
8. Use calipers to measure both ends of the workpiece. —If the test stock is thinner at the tailstock end, move the tailstock toward the back of the lathe 1⁄2 the distance of the amount of taper (see Figure 41). —If the test stock is thicker at the tailstock end, move the tailstock toward the front of the lathe 1⁄2 the distance of the amount of taper (see Figure 40).
Centers Live Centers Figure 42 shows one of the two included MT#3 dead centers and the MT#4 dead center. A live center (not included) has bearings that allow the center tip and the workpiece to rotate together; it can be installed in the tailstock quill for higher speeds. Mounting Dead Center in Spindle MT#4 Dead Center 1. DISCONNECT LATHE FROM POWER! 2.
Removing Center from Spindle 3. To remove the center from the spindle, insert a piece of round bar stock or similar tool through the outboard end (on the left side of the headstock). Have another person hold onto the center with a gloved hand or shop rag, then tap the center loose. Use the quill handwheel to feed the quill out of the casting approximately 1" (see Figure 1).
Steady Rest Mounting Workpiece Between Centers 1. DISCONNECT LATHE FROM POWER! 2. Drill center holes in both ends of the workpiece. 3. Install a dead center in the spindle with a lathe dog and a chuck or faceplate, then install a live center or carbide-tipped dead center in the tailstock. 4. The steady rest supports long shafts and can be mounted anywhere along the length of the bedway. Familiarize yourself with the steady rest components shown in Figure 46 to better understand its operation.
Follow Rest Compound Rest The follow rest mounts to the saddle with two cap screws (see Figure 47). It is used on long, slender parts to prevent workpiece deflection from cutting tool pressure during operation. Adjust the follow rest fingers in the same manner as the those on the steady rest. The compound rest handwheel has an indirectread graduated scale. This means the distance shown on the scale represents the actual distance the tool moves.
Four-Way Tool Post The four-way tool post is mounted on top of the compound rest and allows a maximum of four 1⁄2" tools to be loaded simultaneously. Aligning Cutting Tool with Spindle Centerline For most operations, the cutting tool tip should be aligned with the spindle centerline, as illustrated in Figure 51. Each tool can be quickly indexed to the workpiece by loosening the top handle, rotating the tool post to the desired position, then re-tightening the handle to lock the tool into position.
Tools Needed Qty Hex Wrench 6mm............................................... 1 Steel Shims........................................ As Needed Cutting Tool........................................................ 1 Tailstock Center.................................................. 1 Manual Feed The handwheels shown in Figure 53 allow the operator to manually move the cutting tool. To align the cutting tool with the tailstock center: 1.
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 lathe controls to produce the required spindle speed.
The 33" belt is used on pulleys A and C (see Figure 56) without the tensioner for 720, 1200, and 2400 RPM. C B 3. Tensioner Not Used Open the change gear cover, then loosen the tensioner lock nut located on the other side of the gear cover plate and the headstock. Locking Nut A Figure 56. Positioning belt for high speed. Follow along with the examples below for setting the Model G0602 spindle speed to gain a better understanding of this task. Figure 58. Location of tensioner lock nut. 4.
Follow along with this example for setting the spindle speed for the Model G0752 to gain a better understanding of this task. To set the spindle speed to 150 RPM: 1. DISCONNECT LATHE FROM POWER! 2. Open the change gear cover, use an 8mm hex wrench to loosen the tensioner bolt, then move the tensioner out of the way. 3. Move the V-belt to the outer pulley sheaves to select the low speed range (100-800 RPM), as shown in Figure 59. 4.
Setting Power Feed Rate The feed rate chart on the headstock displays the settings for the feed controls for inch feed rates. Note: All change gears are stamped with the number of teeth they have. 7. Move the lash adjuster so the gear backlash is between 0.003" to 0.008", tighten the lash adjuster cap screw, then close and secure the change gear cover. 8. Loosen the carriage lock (see Figure 60), and push down on the half nut lever to engage the power feed.
Threading 4. Open the change gear cover, loosen the lash adjuster (Figure 61 on Page 45) and swing the change gear assembly out of the way. The following subsections describe how to use the threading controls and charts to set up the lathe for a threading operation. If you are unfamiliar with the process of cutting threads on a lathe, we strongly recommend that you read books, review industry trade magazines, or get formal training before attempting any threading projects. 5.
To set the lathe to cut 0.45 TPmm threads: The steps for setting up the lathe for threading metric threads are the same as those for inch threads. Follow the instructions on Page 46 for setting the thread pitch to 64 TPI, and refer to the chart below. Metric Thread Chart = 0.45 TPmm Figure 63. Metric threading setup.

Annually or When Changing The change gears, shown in Figure 86, should always have a thin coat of heavy grease to minimize corrosion, noise, and wear. Wipe away excess grease that could be thrown onto the V-belts and reduce optimal power transmission from the motor. To lubricate the change gears: 1. DISCONNECT LATHE FROM POWER! 2.
Machine Storage 5. To prevent the development of rust and corrosion, the lathe must be properly prepared if it will be stored for a long period of time. Doing this will ensure the lathe remains in good condition for later use. Loosen or remove all belts so they do not become stretched during the storage period. (Be sure to place a maintenance note near the power button as a reminder that the belts have been loosened or removed.) 6.
SECTION 7: SERVICE Review the troubleshooting procedures in this section if a problem develops with your machine. If you need replacement parts or additional help with a procedure, call our Technical Support. Note: Please gather the serial number and manufacture date of your machine before calling. Troubleshooting Motor & Electrical Symptom Possible Cause Possible Solution Machine does not start or a circuit breaker trips. 1. Emergency stop button engaged or at fault. 6.
Operation Symptom Possible Cause Possible Solution Entire machine vibrates upon startup and while running. 1. Workpiece is unbalanced. 1. Re-install workpiece as centered with the spindle bore as possible. 2. Stop lathe immediately and correct interference problem. 3. Re-tension/replace the V-belt(s) as necessary (see Page 64). 4. Align the V-belt pulleys. 5. Check installation; re-balance chuck or faceplate; contact a local machine shop for help. 6. Adjust change gears and establish backlash. 7.
Symptom Possible Cause Possible Solution Workpiece is tapered. 1. Headstock and tailstock are not properly aligned with each other. 1. Re-align the tailstock to the headstock spindle centerline (see Page 34). Chuck jaws will not move or do not move easily. 1. Chips lodged in the jaws or scroll plate. 1. Remove jaws, clean and lubricate scroll plate and jaws, then replace jaws. Carriage will not feed or is hard to move. 1. Quick-change gears are not all engaged. 2. Half nut lever engaged. 3.
Backlash Adjustment Backlash is the amount of free play felt while changing rotation directions with the handwheel. This can be adjusted on the compound rest and cross slide leadscrews. Before beginning any adjustment, make sure all associated components are cleaned and lubricated, and the locks are loose. Reducing backlash to less than 0.002" is impractical and can lead to accelerated wear to the leadscrew and other components. Avoid the temptation to overtighten the backlash nut or screw while adjusting.
Gib Adjustment Compound Slide Adjustment Fasteners The goal of adjusting the cross slide and compound slide gibs is to remove sloppiness or "play" from the ways without making them overly stiff and difficult to move. In general, loose gibs cause poor finishes and tool chatter; however, over-tightened gibs cause premature wear and make the handwheels difficult to turn. Tools Needed Qty Open-End Wrench 8mm.................................... 1 Hex Wrench 2.5mm............................................
Half Nut Adjustment The clamping pressure of the half nut is fully adjustable with a gib that can be loosened or tightened by two set screws. Use this procedure to adjust the half nut if it becomes loose from wear, or it is too tight for your preferences. A half nut that is too loose will make it difficult to produce accurate work; one that is too tight will increase the rate of wear on itself and the leadscrew. Tools Needed Qty Open-End Wrench 8mm.................................... 1 Hex Wrench 5mm.......
V-Belt Tension & Replacement Lock Bolt V-Belts stretch and wear with use, so check the tension on a monthly basis to ensure optimal power transmission. Replace the V-belts if they become cracked, frayed, or glazed. On the Model G0602, the low range V-belt tension is controlled by a tensioner between the secondary drive pulley (B) and spindle (C) pulley. The high range V-belt between the spindle (C) and motor (A) pulleys is tensioned by the motor. Tensioner Figure 94. Model G0752 tensioner and lock bolt.
To tension the Model G0602 high range V-belt: 1. Follow Steps 1–3 in "Tensioning Timing Belt" on Page 65. 2. Lower the motor and re-tighten the mounting hex nuts. The high range V-belt is correctly tensioned when there is approximately 1⁄4" deflection when it is pushed with moderate pressure, as shown in Figure 95 on Page 63.
Timing Belt Tension & Replacement Pulley Deflection On the Model G0602 the timing belt transfers power from the motor to the secondary drive pulley (see Figure 99). If the timing belt becomes excessively worn or damaged, you will need to replace it. 1 Pulley Figure 100. Correct timing-belt deflection.
