Indicates an imminently hazardous situation which, if not avoided, WILL result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, COULD result in death or serious injury. Indicates a potentially hazardous situation which, if not avoided, MAY result in minor or moderate injury. It may also be used to alert against unsafe practices. NOTICE This symbol is used to alert the user to useful information about proper operation of the machine. Safety Instructions for Machinery OWNER’S MANUAL. Read and understand this owner’s manual BEFORE using machine. TRAINED OPERATORS ONLY. Untrained operators have a higher risk of being hurt or killed. Only allow trained/supervised people to use this machine. When machine is not being used, disconnect power, remove switch keys, or lock-out machine to prevent unauthorized use—especially around children. Make 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. Model G0758 (Mfd. Since 2/14) 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. -7- 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 avoid accidental slips, which could cause loss of workpiece control. HAZARDOUS DUST. Dust 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 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. -8- 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 recommended 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.

Avoid cord damage by keeping it away from heated surfaces, high traffic areas, harsh chemicals, and wet/damp locations. EXPERIENCING DIFFICULTIES. If at any time you experience difficulties performing the intended operation, stop using the machine! Contact our Technical Support at (570) 546-9663. Model G0758 (Mfd. Since 2/14) Additional Safety for Mills/Drills The primary risks of operating a Mill/Drill are as follows: You can be seriously injured or killed by getting clothing, jewelry, or long hair entangled with rotating cutter. You can be severely cut or your fingers can be amputated by contacting the rotating cutter. You can be blinded or struck with great force by broken cutting tools, metal chips, workpieces, or adjustment tools thrown from the rotating spindle. To reduce your risk of serious injury when operating this machine, completely heed and understand the following: UNDERSTAND ALL CONTROLS. Make sure you understand the function and proper use of all controls before starting. This will help you avoid making mistakes that result in serious injury. WEAR FACE SHIELD. Always wear a face shield in addition to safety glasses. This provides more complete protection for your face than safety glasses alone. REMOVE CHUCK KEY & SPINDLE TOOLS. Always remove chuck key, drawbar wrench, and other tools used on the spindle immediately after use. This will prevent them from being thrown by the spindle upon startup. PROPERLY SECURE CUTTER. Firmly secure cutting tool or drill bit so it does not fly out of spindle during operation. USE CORRECT SPINDLE SPEED. Follow recommended speeds and feeds for each size and type of cutting tool. This helps ensure best cutting results and avoid tool breakage during operation. INSPECT CUTTING TOOL. Inspect cutting tools for sharpness, chips, or cracks before each use. Replace dull, chipped, or cracked cutting tools immediately. ALLOW SPINDLE TO STOP. To minimize your risk of entanglement, always allow spindle to stop on its own. DO NOT stop spindle using your hand or any other object. SECURE WORKPIECE TO TABLE. Clamp workpiece to table or secure in a vise mounted to table, so workpiece cannot unexpectedly shift or spin during operation. NEVER hold workpiece by hand during operation. CLEAN MACHINE SAFELY. Metal chips or shavings can be razor sharp. DO NOT clear chips by hand or compressed air that can force chips farther into machine—use a brush or vacuum instead. Never clear chips while spindle is turning. PROPERLY MAINTAIN MACHINE. Keep machine in proper working condition to help ensure that it functions safely and all guards and other components work as intended. Perform routine inspections and all necessary maintenance. Never operate machine with damaged or worn parts that can break or result in unexpected movement during operation. DISCONNECT POWER FIRST. To reduce risk of electrocution or injury from unexpected startup, make sure mill/drill is turned OFF, disconnected from power, and all moving parts have come to a complete stop before changing cutting tools or starting any inspection, adjustment, or maintenance procedure. POWER DISRUPTION. In the event of a local power outage during operation, turn spindle switch OFF to avoid a possible sudden startup once power is restored. Like all machinery there is potential danger when operating this machine. Accidents are frequently caused by lack of familiarity or failure to pay attention. Use this machine with respect and caution to lessen the possibility of operator injury. If normal safety precautions are overlooked or ignored, serious personal injury may occur. Model G0758 (Mfd. Since 2/14) -9- 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. 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 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 the 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. -10- 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. 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 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 service personnel to ensure circuit is properly sized for safe operation. Model G0758 (Mfd. Since 2/14) 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 (similar to the figure below). 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. GROUNDED 5-15 RECEPTACLE Grounding Prong 5-15 PLUG Neutral Hot Figure 5. Typical 5-15 plug and receptacle. 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 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............................16 AWG Maximum Length (Shorter is Better).......50 ft. 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. Model G0758 (Mfd. Since 2/14) -11- SECTION 3: SETUP Needed for Setup This machine presents serious injury hazards to untrained users.

Since 2/14) -13- 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. There are many ways to remove this rust preventative, but the following steps work well in a wide variety of situations. Always follow the manufacturer’s instructions with any cleaning product you use and make sure you work in a well-ventilated area to minimize exposure to toxic fumes. Before cleaning, gather the following: • Disposable rags • Cleaner/degreaser (WD•40 works well) • Safety glasses & disposable gloves • Plastic paint scraper (optional) Gasoline and petroleum products have low flash points and can explode or cause fire if used to clean machinery. Avo i d u sing t h e s e p r o d u c t s to c l e a n m a c hin e r y. Many cleaning solvents are toxic if inhaled. Only work in a well-ventilated area. NOTICE Avoid chlorine-based solvents, such as acetone or brake parts cleaner, that may damage painted surfaces. T23692—Orange Power Degreaser A great product for removing the waxy shipping grease from machine during clean up. Basic steps for removing rust preventative: 1. Put on safety glasses. 2. Coat the rust preventative with a liberal amount of cleaner/degreaser, then let it soak for 5–10 minutes. 3. Wipe off the surfaces.

Since 2/14) 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. The physical environment where the machine is operated is important for safe operation and longevity of machine components. For best results, operate this machine in a dry environment that is free from excessive moisture, hazardous chemicals, airborne abrasives, or extreme conditions. Extreme conditions for this type of machinery are generally those where the ambient temperature range exceeds 41°–104°F; the relative humidity range exceeds 20%–95% (non-condensing); or the environment is subject to vibration, shocks, or bumps. Space Allocation Consider the largest size of workpiece that will be processed through this machine and provide enough space around the machine for adequate operator material handling or the installation of auxiliary equipment. With permanent installations, leave enough space around the machine to open or remove doors/covers as required by the maintenance and service described in this manual. See below for required space allocation. Children or untrained people may be seriously injured by this machine. Only install in an access restricted location. Electrical Installation Place this machine near an existing power source. Make sure all power cords are protected from traffic, material handling, moisture, chemicals, or other hazards. Make sure to leave enough space around machine to disconnect power supply or apply a lockout/tagout device, if required. Lighting Lighting around the machine must be adequate enough that operations can be performed safely. Shadows, glare, or strobe effects that may distract or impede the operator must be eliminated. 21" 193/4" 301/4" Figure 8. G0758 working clearances. Model G0758 (Mfd.

Since 2/14) -17- Joining Drill Chuck & Arbor A B-16 x R8 arbor is included for the drill chuck that comes with this machine. The following procedure describes how to install the arbor in the chuck. 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 getting a new arbor for that chuck. Lubricating Mill/Drill The lubrication procedures highlighted in the Lubrication subsection of SECTION 6: MAINTENANCE must be completed before performing the test run or spindle break-in. Damage caused by running the mill/drill without first properly lubricating headstock gears will not be covered under warranty. Important: DO NOT install the drill chuck and arbor into the spindle until AFTER the test run. To join drill chuck and arbor: 1. Use mineral spirits 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 arbor and tap chuck onto a block of wood with medium force, as illustrated in Figure 15. Figure 15. Tapping drill chuck/arbor on block of wood. 5. Attempt to separate drill chuck and arbor by hand­. If you can pull them apart, repeat this procedure. Note: Refer to Installing/Removing Tooling section on Page 25 for installing arbor into spindle instructions. -18- Model G0758 (Mfd. Since 2/14) Test Run 3. Rotate variable-speed knob to lowest setting. 4. Rotate high/low gearbox knob to low "L" gear setting (see Figure 17). Once assembly is complete, test run the machine to ensure it is properly connected to power and safety components are functioning properly. Note: When switching between gears, it may be necessary to rotate spindle by hand so gears will align and engage. 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. High/Low Gearbox Knob 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. Figure 17. Gearbox knob rotated to low setting.

Congratulations! The Test Run is complete. Continue to Spindle Break-In. OFF Button Figure 16. Location of mill/drill controls (front). Model G0758 (Mfd. Since 2/14) -19- Spindle Break-In The spindle break-in procedure distributes lubrication throughout the bearings to reduce the risk of early bearing failure if there are any "dry" spots or areas where lubrication has settled in the bearings. You must complete this procedure before placing operational loads on the spindle for the first time when the machine is new or if it has been sitting idle for longer than 6 months. Always start the spindle break-in at the lowest speed to minimize wear if there are dry spots. Allow the spindle to run long enough to warm up and distribute the bearing grease, then incrementally increase spindle speeds, allowing the spindle to run the same amount of time at each speed, until reaching the maximum spindle speed. Following the break-in procedure in this progressive manner helps minimize any potential wear that could occur until lubrication is fully distributed. You must complete this procedure to maintain the warranty. Failure to do this could cause rapid wear-and-tear of spindle bearings once they are placed under load. To perform spindle break-in procedure: 1. Rotate variable-speed knob to 50 RPM and high/low gearbox knob to low "L". 2. Press ON button. 3. Run spindle for minimum of 10 minutes. 4. Without stopping spindle, use variable-speed knob to run machine at 500 and 1000 RPM for 10 minutes each. 5. Press OFF button. -20- 6. Rotate variable-speed knob to 100 RPM and high/low gearbox knob to high "H". 7. Press ON button. 8. Run machine for a minimum of 10 minutes. 9. Without stopping spindle, use variable-speed knob to run machine at 1000 and 2000 RPM for 10 minutes each. 10. Press OFF button. The spindle break-in of the machine is now complete!

Hold onto tooling with one hand and fully unthread drawbar. 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 operation, you will need to: 1) Determine the best spindle speed for the cutting/drilling task, and 2) adjust the gear box knob and variable-speed knob to produce determined 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 29. *Recommended Cutting Speed (FPM) x 12 Tool Dia. (in inches) x 3.14 Spindle = Speed (RPM) *Double if using carbide cutting tool Figure 29. Formula for determining best spindle speed. 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. -26- Model G0758 (Mfd.

Since 2/14) -27- 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 the machine, follow this maintenance schedule and refer to any specific instructions given in this section. Daily Check: • Loose mounting bolts. • Damaged tooling. • Clean debris and built up grime off of machine. • Worn or damaged wires. Any other unsafe condition. • Every 8 Hours of Operation: • Lubricate table and column ways (Page 29). • Lubricate quill outside surface (Page 31). Every 40 Hours of Operation: • Lubricate table leadscrews (Page 30). Every 90 Hours of Operation: • Headstock gears (Page 30). • Lubricate quill rack (Page 31). Every 120 Hours of Operation: • Lubricate column leadscrew (Page 29). Cleaning and Protecting Metal chips left on the machine that have been soaked with water-based coolant 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 mill/drill and treat with a nonstaining lubricant after cleaning. Protect other unpainted cast iron surfaces with regular applications of products like G96® Gun Treatment, SLIPIT®, or Boeshield ® T-9. (See Accessories on Page 27 for more details.) 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 over time, which makes them hard to move. Clean all exterior components in this section with mineral spirits, shop rags, and brushes before lubricating. DISCONNECT MACHINE FROM POWER BEFORE PERFORMING LUBRICATION! Follow reasonable lubrication practices as outlined in this manual. Failure to do so could lead to premature failure of machine and will void warranty. -28- Model G0758 (Mfd.

Frequently clean away chips that load up during milling operations. 3. Lubricate ways (Page 29). 4. Check to make sure that all table limit stops are not in the way. 5. Adjust gibs (see Page 34). 1. Set spindle speed correctly (Page 26) or use a slower feed rate. 2. Sharpen cutting tool or select one that better suits 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. -33- Adjusting Gibs Gibs are tapered lengths of metal sandwiched between two moving surfaces to control how much friction they have when they slide past one another. Correctly adjusting the gibs is critical to producing accurate milling results. Tight gibs make table movement more accurate but stiff. Loose gibs make table movement sloppy but easy. The goal of gib adjustment is to remove unnecessary sloppiness without causing the ways to bind. Tip: Many experienced machinists adjust the gibs until there is just a slight drag in table movement. Screws on each end allow gib adjustment to increase or decrease the friction between the sliding surfaces of the ways. DISCONNECT MACHINE FROM BEFORE ADJUSTING THE GIBS! POWER Make sure all table locks are loose. Then, loosen one gib adjustment screw (see Figure 44) and tighten the opposing screw the same amount to move the gib, while at the same time using the handwheels to move the table until you feel a slight drag in that path of movement. Adjusting Leadscrew Backlash Leadscrew backlash is the amount of free-play movement in the leadscrew (when changing the direction of rotation) before the attached device begins to move. Leadscrews must have a certain amount of backlash, but over time, this will increase with normal 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 by using a long 5mm hex wrench to tighten/loosen the cap screw on the leadscrew nut. This adjusts the force the split leadscrew nut exerts on the leadscrew threads. The X-axis leadscrew nut shown in Figure 45 is accessed from underneath the left side of the table.

Since 2/14) Brush Replacement 3. This mill/drill is equipped with a universal motor that uses two carbon brushes to transmit electrical current inside the motor. These brushes are considered to be regular "wear items" or "consumables" that will need to be replaced during the life of the motor. The frequency of required replacement is often related to how much the motor is used and how hard it is pushed. Unscrew one of the brush caps (see Figure 47). Brush Cap Replace the carbon brushes (part number: P0758202) when the motor no longer reaches full power, or when the brushes measure less than 1⁄4" long (new brushes are 5 ⁄ 8" long). Tools Needed: Qty Hex Wrench 3mm............................................... 1 Standard Screwdriver #2.................................... 1 Figure 47. Removing motor brush cap. 4. To inspect and replace motor brushes: 1. DISCONNECT MACHINE FROM POWER! 2. Uninstall motor cover by removing cap screws (see Figure 46). Remove old brush assembly. If brush is worn down to less than 1⁄4'', then replace it with a new one. Otherwise re-install old brush (see Figure 48). Brush Assembly Cap Screw (1 of 4) Figure 48. Inserting new motor brush. Figure 46. Location of motor cover cap screws. Model G0758 (Mfd. Since 2/14) 5. Replace brush cap to secure brush. 6. Repeat Steps 3–5 for second brush assembly on other side of motor. 7.

If there are differences between your machine and what is shown in this section, call Technical Support at (570) 546-9663 for assistance BEFORE making any changes to the wiring on your machine. An updated wiring diagram may be available. Note: Please gather the serial number and manufacture date of your machine before calling. This information can be found on the main machine label. Wiring Safety Instructions SHOCK HAZARD. Working on wiring that is connected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components! MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire. This includes the installation of unapproved aftermarket parts. WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components. MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box. WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections. CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors. CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source. EXPERIENCING DIFFICULTIES.
