6 GROUNDING WARNING! Improperly connecting the grounding wire can result in the risk of electric shock. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician. GROUNDED TOOLS: TOOLS WITH THREE PRONG PLUGS 1. Tools marked with Grounding Required have a three wire cord and three prong grounding plug. The plug must be connected to a properly grounded outlet. If the tool should electrically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user, reducing the risk of electric shock. (See Figure A.) 2. The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool. The green wire in the cord must be the only wire connected to the tool s grounding system and must never be attached to an electrically live terminal. (See Figure A.) 3. Your tool must be plugged into an appropriate outlet, properly installed and grounded in accordance with all codes and ordinances. The plug and outlet should look like those in the following illustration. (See Figure A.) THIS PRODUCT USES A 3-PRONG PLUG 120 VOLT, GROUNDED, ELECTRICAL OUTLET FIGURE A SKU For technical questions, please call PAGE 6

7 DOUBLE INSULATED TOOLS: TOOLS WITH TWO PRONG PLUGS 4. Tools marked Double Insulated do not require grounding. They have a special double insulation system which satisfies OSHA requirements and complies with the applicable standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the National Electrical Code. (See Figure B.) 5. Double insulated tools may be used in either of the 120 volt outlets shown in the following illustration. (See Figure B.) THIS PRODUCT DOES NOT USE A 2-PRONG PLUG 120 VOLT, GROUNDED, ELECTRICAL OUTLETS FIGURE B EXTENSION CORDS 1. Grounded tools require a three wire extension cord. Double Insulated tools can use either a two or three wire extension cord. 2. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension cords with inadequately sized wire causes a serious drop in voltage, resulting in loss of power and possible tool damage. (See Figure C, next page.) 3. The smaller the gauge number of the wire, the greater the capacity of the cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge cord. (See Figure C.) 4. When using more than one extension cord to make up the total length, make sure each cord contains at least the minimum wire size required. (See Figure C.) 5. If you are using one extension cord for more than one tool, add the nameplate SKU For technical questions, please call PAGE 7

8 amperes and use the sum to determine the required minimum cord size. (See Figure C.) 6. Make sure your extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it. 7. Protect your extension cords from sharp objects, excessive heat, and damp or wet areas. RECOMMENDED MINIMUM WIRE GAUGE FOR EXTENSION CORDS* (110 VOLT) FIGURE C *Based on limiting the line voltage drop to five volts at 150% of the rated amperes.

10 1. The Bed Way (1) is especially hardened which ensures rigidity and low vibration. The Head Stock (41), Tail Stock (90), and Lead Screw (94) are mounted on the Bed Way. (See Figure E.) 2. The Dust Guard (29) is mounted on the left side of the Head Stock (41) and Bed Way (1). The Dust Guard protects the Motor (58), V-Belt (48), and V-Pulley (49). (See Figure E and Assy. Diagram.) 3. The 3-Jaw Chuck (30) is self-centering and is mounted on the Spindle (31). To remove the Chuck, simply remove the three securing Nuts to the rear of the Spindle. This allows the Chuck to be pulled free along with its three mounting Studs. (See Figure E.) 4. Within the Head Stock (41) is the Motor (58). The Motor provides a direct drive to the Spindle (31) via the internal V-Belt (48), and is regulated by the Variable Speed Control Knob (63). (See Figure E.) 5. The Emergency Stop Button (62) is located on the Head Stock (41), and is activated by pressing down on the Button. (See Figure E.) 6. The Variable Speed Control Knob (63) is also located on the Head Stock (41). To turn on the Micro Mini Lathe, turn the Variable Speed Control Knob clockwise. A click will be heard as power is turned on, but the Spindle (31) will not rotate until the Knob is turned clockwise a little further. Speed will increase progressively the further the Knob is turned. To turn off the Lathe, turn the Variable Speed Control counterclockwise. (See Figure E.) 7. The Automatic Overload Light (64) is yellow in color. The power supply system of this Lathe has an automatic overload protective device. If cutting or drilling too deep, the system will stop working, and the yellow Light will illuminate. Should this occur, turn off the Variable Speed Control Knob (63), and then turn it on again. The system will operate once again, and the yellow Light will turn off automatically. (See Figure E.) 8. The Power On Light (65) is green in color and will illuminate when the Variable Speed Control Knob (63) is turned clockwise to turn on the Lathe. (See Figure E.) 9. The Fuse Holder (67) is located at the back of the Lathe. Should the Lathe not turn on, check to make sure the machine s Power Cord/Plug (16) is connected to a working, 110 volt, grounded outlet. Then make sure to turn the Variable Speed Control Knob (63) clockwise. Should the Lathe still not turn on, disconnect the Power Cord/Plug from its electrical outlet.

11 10. The Chuck Protective Cover (70) must always be fully lowered prior to turning on the Micro Mini Lathe. The Chuck Protective Cover helps prevent metal/wood shavings and coolant (if used) from being thrown out toward the operator. (See Figure E.) 11. The Tool Rest (79) must be used with cutting tools (not included) that can be properly mounted to the Rest, with as little overhang of the tool as possible. Ideally, the overhang should be approximately 1/4 to 3/8 for a straight cutting tool. A cutting tool can be secured in the Tool Rest using the three Hex Socket Head Screws (3, 34) located at the top of the Tool Rest. (See Figure E.) 12. The Tail Stock (90) may be moved along the Bed Way (1) to any desired position, and is secured in position with the Screw (81) located at the front of the Tail Stock. (See Figure E.) 13. The Saddle Hand Wheel (23C) operates the Saddle (103), onto which is mounted the Tool Rest (79). Adjusting the Saddle and Tool Rest allows for intricate and delicate operations to be performed. (See Figure E.) ASSEMBLY INSTRUCTIONS 1. Assembly requires attaching the Tail Stock Hand Wheel (23A), Lead Screw Hand Wheel (23B), and Saddle Hand Wheel (23C) to the Lathe. Each Hand Wheel is identical to the others in size and construction. To secure the Hand Wheels, use one Cap Nut (24) for each Hand Wheel. (See Figure E.) 2. The Chuck Protective Cover (70) must also be attached to the Lathe. To do so, align the two mounting holes in the Chuck Protective Cover with the two threaded mounting holes in the Rotator Shaft (71). Then secure the Chuck Protective Cover to the Rotator Shaft, using two Screws (69). (See Figure E and Assy. Diagram.) MOUNTING THE MICRO MINI LATHE 1. CAUTION! Make sure the workbench on which the Micro Mini Lathe will be placed is flat, level, dry, and sturdy enough to handle the weight of the Lathe, its accessories, any additional tools, and the workpieces. 2.

12 SET-UP INSTRUCTIONS 1. The following Steps are guidelines on how to set up the Micro Mini Lathe in order to perform a simple turning operation. 2. Always plan your work. Have drawings or a plan on hand along with any measuring instruments you may require such as, micrometers, verniers, calipers, etc. 3. Select a cutting tool (not included) that will produce the desired cut. Mount the cutting tool in the Tool Rest (79) with approximately 1/4 to 3/8 overhang from the Tool Rest. 4. IMPORTANT: Make sure the tip of the cutting tool is on the center line of the work, or just slightly below it. If necessary, shims (not included) should be used beneath the cutting tool to achieve the proper height. To ensure the tip of the cutting tool is at the proper height, position the tool so that its tip is almost touching the point of the Tail Stock (90) center. If necessary, make adjustments using the shims. 5. Securely mount the workpiece between the 3-Jaw Chuck (30) and the Tail Stock (90). NOTE: If the Tail Stock is not to be used, you may remove the Screw (81) that secures the Tail Stock in place. Then, slide the Tail Stock off the Bed Way (1). 6. Mark the surface of the workpiece at the point where the cut is to end. Move the Saddle (103) so that the cutting tool is directly opposite the mark. Then, turn the Saddle Hand Wheel (23C) so that the cutting tool touches the surface of the workpiece. 7. Rotate the 3-Jaw Chuck (30) by hand to ensure it will not come into contact with anything (i.e., Saddle, Tool Rest, cutting tool, etc.) when the machine is turned on. 8. Turn the Saddle Hand Wheel (23C) to retract the cutting tool away from the workpiece. Use the 3-Jaw Chuck to rotate the workpiece by hand. At any point along the length of the workpiece to be cut, move the cutting tool slowly until it just touches the surface. Record this position by zeroing the Scale. Example: Turn the moveable Scale until the cutting tool is a short distance from the right hand edge of the workpiece. Move the Saddle Hand Wheel (23C) one full turn until the zero marks again coincide. (See Figure F, next page.) IMPORTANT: If you go past the zero marks on the Scale, back off again at least one-half turn of the Saddle Hand Wheel (23C). Then, slowly bring the marks back together. (See Figure F, next page.) SKU For technical questions, please call PAGE 12

13 SCALE SADDLE HAND WHEEL (23C) FIGURE F 9. Continue turning the Saddle Hand Wheel (23C) an amount equivalent to your desired depth of cut. NOTE: It is recommended that for rough cutting, you do not exceed as your depth of cut. OPERATING INSTRUCTIONS 1. Use the Lead Screw Hand Wheel (23B) and Saddle Hand Wheel (23C) to move the cutting tool to its cutting position. Make sure the cutting tool does not contact the workpiece. 2. Make sure the Variable Speed Control Knob (63) is in its OFF position. Then plug the Power Cord/Plug (16) into the nearest 110 volt, grounded, electrical outlet. 3.

14 Middle Saddle Adjustments: SETTINGS AND ADJUSTMENTS 1. The Middle Saddle (106) is mounted on the Saddle (103). Between the sloping surfaces on one side of the Middle Saddle a jib strip is inserted, which may be tightened against the Saddle with the three adjuster or jib Screws (91, 92) and three Nuts (18) mounted along its length. (See Figure G.) 2. The three jib Screws (91, 92) are located on the right side of the Middle Saddle (106). In time, wear will occur on the inner surfaces of the Middle Saddle and Saddle (103) resulting in a sloppiness of action. To adjust the jib strip to account for wear and to ensure the Middle Saddle moves evenly and smoothly along the Saddle, proceed as follows: A. Loosen the three Nuts (18), and screw in the three jib Screws (91, 92) evenly. The Middle Saddle (106) should be held against the Saddle (103) firmly. Test by attempting to turn the Saddle Hand Wheel (23C), but do not force it. (See Figure G.) B. Screw out each of the three jib Screws (91, 92) by one quarter of a turn only. Then, retighten the Nuts (18). (See Figure G.) C. Test again by turning the Saddle Hand Wheel (23C). The sliding movement of the Middle Saddle (106) should be even and smooth along its complete length. (See Figure G.) D. If the movement is too slack, screw all jib Screws (91, 92) in by one eighth of a turn. Then, re-try. If the movement is too stiff, screw out the jib Screws by one eighth of a turn until the proper adjustment is obtained. (See Figure G.) E. Tighten all three Nuts (18), taking care not to move the jib Screws (91, 92) while doing so. (See Figure G.) F. When finished, retract the Middle Saddle (106) fully and apply machine oil to all mating surfaces. Then, move the Middle Saddle to its normal position. (See Figure G.)
