Additional Safety for Power Feeders 1. SAFETY ACCESSORIES. Always use appropriate machine guards. 2. TOOL SPEED. Make sure all cutting tools are rotating at the operating speed before feeding the workpiece. 3. FEEDING SPEED. DO NOT overload the cutting tool by feeding too quickly. The cutting tool will perform better and be safer to work with at the rate for which it was designed. 4. HAND SAFETY. Keep hands away from rotating parts on the feeder and the cutting tool.
SECTION 2: CIRCUIT REQUIREMENTS 220V Operation Serious personal injury could occur if you connect the machine to power before completing the setup process. DO NOT connect the machine to the power until instructed later in this manual. Power Connection Device The type of plug required to connect your machine to power depends on the type of service you currently have or plan to install. For 220V singlephase operation we recommend using the plug shown in Figure 2.
SECTION 3: SETUP Setup Safety 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! Items Needed for Setup The following items are needed to complete the setup process, but are not included with your machine: Description Qty • Safety Glasses............................................ 1 • Light Machine Oil .....................
Inventory A The following is a description of the main components shipped with your machine. Lay the components out to inventory them. B Note: If you can't find an item on this list, check the mounting location on the machine or examine the packaging materials carefully. Occasionally we pre-install certain components for shipping purposes. Box Inventory (Figures 4 & 5) Qty A. Power Feeder Assembly............................. 1 B. Lubricator.................................................... 1 C.
Clean Up The unpainted surfaces are coated with a waxy oil to prevent corrosion during shipment. Remove this protective coating with a solvent cleaner or degreaser, such as shown in Figure ??. For thorough cleaning, some parts must be removed. For optimum performance, clean all moving parts or sliding contact surfaces. Avoid chlorine-based solvents, such as acetone or brake parts cleaner that may damage painted surfaces. Always follow the manufacturer’s instructions when using any type of cleaning product.
Base Mounting Whichever way you mount your power feeder, you must be able to use the handcranks and lock levers to position the rubber wheels parallel with the table surface and 1⁄8" lower than the thickness of your workpiece. Position the power feeder on the table top to determine where to drill your base mounting holes, so you can maximize power feeder swing and adjustment options. Also, you must be able to point the power feeder slightly towards the machine fence (Figure 8).
Mounting Options To correctly position this power feeder on your table top, completely assemble the power feeder first, then refer to this section and mount your base to the table using one of the two methods below. The reason for this order is that with the power feeder unit completely assembled, it will be easier to locate where on the table top you will need to drill your base mounting holes, so you can take advantage of the full range of power feeder swing and adjustments.
Test Run Once power feeder assembly is complete and mounted on the table, you must test run your power feeder to make sure it runs properly. If, during the test run, you cannot easily locate the source of an unusual noise or vibration, stop using the power feeder immediately, then review the Troubleshooting table on Page ???. If you still cannot remedy a problem, contact our Technical Support at (570) 546-9663 for assistance. 6.
SECTION 4: OPERATIONS Operation Safety To reduce the risk of serious injury when using this machine, read and understand this entire manual before beginning any operations. Damage to your eyes and lungs could result from using woodworking machinery without proper protective gear. Always wear safety glasses and a respirator when operating this machine. Basic Use and Care You MUST assemble all guards, fences, and hold-downs before starting your machine or power feeder.
Changing Feed Speed 3. Refer to the change gear chart (Figure 13) below to find the gear combination required for your chosen feed rate. Your power feeder has the option to feed a workpiece at 13, 26, 33, and 66 feet per minute. These rates are achieved by changing the combination of change gears, shown in Figure 12, and turning the motor switch to high or low range operation, shown in Figure 13. 4. Remove the chain cover and the two hex nuts securing the position A & B change gears to the shafts. 5.
SECTION 5: MAINTENANCE Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Schedule For optimum performance from your machine, follow this maintenance schedule and refer to any specific instructions given in this section. • After the first 200 hours of use, or after the first month, change the gearbox oil with 5.1 fluid ounces of a good automotive grade 80-90W gear oil.
SECTION 6: SERVICE Review the troubleshooting and procedures in this section to fix or adjust your machine if a problem develops. If you need replacement parts or you are unsure of your repair skills, then feel free to call our Technical Support at (570) 546-9663. Troubleshooting Motor & Electrical Symptom Possible Cause Possible Solution Motor will not start. 1. Check power supply for proper voltage. 1. Low voltage. 2. Open circuit in motor or loose connections. 2.
Wheel Replacement 2. Using a 5mm hex wrench, remove the two wheel retaining cap screws (Figure 16). Always disconnect power to the machine before performing maintenance. Failure to do this may result in serious personal injury. Cap Screw If you damage one or more wheels, you can easily replace the wheels. Figure 16. Wheel replacement. Tools Needed Qty • Hex Wrench 5mm........................................ 1 3. Swap the old wheel with the new. To replace a wheel: 4.
