SAFETY Electrical Requirements 220V Operation The SHOP FOX® Model W1709 has a 71⁄2 HP, 220V single-phase sanding motor, a 1⁄2 HP, 220V feed motor, and a 1⁄3 HP table lift motor. TURN-OFF and LOCK your master power switch so no power is available to the sander before connecting electrical wires! If you ignore this warning serious electrical shock may occur causing injury or death! Use a 50 amp circuit breaker and a circuit that has wiring rated to handle this amperage draw.
ASSEMBLY Unpacking The Model W1709 has been carefully packaged for safe transporting. If you notice the machine has been damaged, please contact Woodstock International Service and Support at 1-360-7343482 or send e-mail to: tech-support@shopfox.biz. Box Contents The following is a description of the components shipped with the SHOP FOX® W1709. Lay the components out in a similar fashion to those in Figure 6. This will help in identification before beginning assembly.
Shop Preparation ASSEMBLY • • • Cleaning Machine Floor Load and Balance: Your sander represents a large weight load in a small footprint. Most commercial floors are suitable for the sander. Some residential floors may require additional bracing to support both machine and operator. Make sure the sander operates on a level surface by placing a level gauge on the conveyor table and using a wrench to adjust the feet until the machine is level.
Air Hose Installation Push your air supply hose on to the air pressure regulator inlet fitting, and clamp it in place with a hose clamp as shown in Figure 7. If you prefer, you can replace the included air nozzle with a 3⁄8" male quick connect air coupling. When the air hose is installed, pull up and rotate the regulator air pressure knob until the gauge reads 57 PSI then push down. DO NOT attempt to regulate the air pressure with the ON/OFF air supply lever.
Dust Collection The Model W1709 features a dust port and an adapter located on top of the machine as shown in Figures 10 and 11. Before performing any sanding operation, attach the dust port to a 2HP or better dust collector, which can draw at least 1,200 CFMs, or dust buildup will hinder the performance of your sander. ASSEMBLY Even with a sufficient dust collection system, a fine layer of dust may still be present on your stock as it comes out of the sander. This residual dust is a normal condition.
ADJUSTMENTS General Information The adjustments in this section have been factory set and generally do not need to be performed when you first receive your sander. However, before operating your sander become familiar with these adjustments, as they will help you achieve the sanding results you want. KEEP loose clothing and long hair secured and away from moving parts.
Belt Tracking The belt tracking is adjusted by lengthening or shortening a air cylinder pushrod (Figure 14). This adjustment is responsible for keeping the belt in “same-speed” left-to-right motion during sanding. Your goal is to adjust the pushrod length until the belt left-and-right movement takes approximately the same amount of time. KEEP loose clothing and long hair secured and away from moving parts.
Belt Oscillation Speed For normal operations, the oscillation speed should be set so that it takes approximately one second to move each direction of travel, or a total of two seconds to move both directions. KEEP loose clothing and long hair secured and away from moving parts. However, you can experiment with different speeds to see how the results may affect your finished product. Often, you may find that certain speeds yield better results for different varieties of stock and the feed rates chosen.
Belt Tracking Safety Switch Adjustment Bolt Belt tracking safety switches are placed on both sides of the belt to act as emergency machine stops if the belt travels too far to one side during oscillation. See Figure 16. ADJUSTMENTS To adjust the belt tracking safety switches, do these steps: 1. TURN-OFF and LOCK the master power switch so no power can go to your sander! 2. Make sure the belt tracking and oscillation is adjusted. 3.
Pressure Rollers Belt Tension Knob The pressure rollers are factory set so they are parallel with each other, parallel with the sanding drum, and parallel with the surface of the conveyor table. Additionally, the front pressure rollers must be set 0.040" below the sanding drum, and the rear rollers at 0.020" below the sanding drum. When these settings are achieved, the pressure-roller spring tension will be correct.
V-Belt Tension The sanding motor V-belts that drive the sanding rollers (Figure 19) and the table lift motor that adjust table height (Figure 20), must be tensioned properly for best performance. Only replace the belt if it becomes frayed, cracked, or glazed. If one belt is bad, always replace both belts as a matched set. NOTE, Both table lift and sanding motor belts are adjusted the same way. Tension Adjustment Nut ADJUSTMENTS KEEP the sanding drum drive belts correctly adjusted.
Feed Belt Tension and Tracking The feed belt tension and tracking has been set at the factory; however, if at any point you notice that your feed belt is slipping or tracking off center on the rollers and loading up on the positioning wheels under the conveyor table, you must adjust the feed belt tension and tracking. To adjust the feed belt tension and tracking, do these steps: 1. Lift and hold the emergency stop plate up and out of the way. See Figure 21. 2.
Table Stop Switches The table stop switches prevent the table lift motor from running the table into the sanding drum and bottoming out the table lift mechanism at the end of the jack screws. Periodically adjust the table stop switches. ADJUSTMENTS To adjust table stop switches, do these steps: 1. Apply air to the sander and tension the sanding belt. 2. Push the down arrow key and lower the table until you achieve 6 inches between the sanding drum and the conveyor table surface. See Figure 22. 3.
OPERATIONS Control Panel • Table Start and Stop Keys: Cycles the table lift motor in and out of the automatic raise and lower function. Below is a summary of your sander control panel and the components that it controls. Use this information to become familiar with your sander. See Figure 24. • Sanding Load Amp Meter: Indicates the current amp load on the sanding motor when a sanding operation is in progress. • Power Lamp: Indicates when machine has power to the control panel.
Test Run Once assembly is complete, the machine is ready for a test run. The purpose of a test run is to identify any unusual noises and vibrations, as well as to confirm that the machine is performing as intended. ALWAYS wear safety glasses and a respirator during operations. Serious injury may occur if this is warning is ignored! OPERATIONS To complete the test run, do these steps: 1. Tie back loose clothing and hair, and wear a respirator and safety glasses. 2.
Setting Feed Speed The feed belt motor offers speeds of 16.4, 23, and 32.8. Figure 24 points out the variable conveyor feed speed control knob. To change the feed belt speed do these steps: 1. TURN-OFF and LOCK the master power switch so power cannot start your sander! 2. Remove the 6mm Allen screw in the center of the chain cover and remove the cover. 3. Use a 7⁄8" Allen wrench and loosen the two motor retaining bolts. 4. Pivot the motor upward and move the chain to the required set of sprockets.
Emergency Stop When pushed, the emergency stop plate shown in Figure 26 stops electricity to the motors and stops the sander quickly by using a disc brake on the drive motor. KEEP the sanding drum drive belts correctly adjusted. If the belts are loose, and the emergency stop is engaged, the sanding drum pulley will slip and not immediately stop in the event of an emergency! To apply the emergency stop, do these steps: 1. Push the bottom of the emergency stop plate as far as it will go. 2.
3. Use the numeric key pad and enter the thickness of your calibration board (Example: 1.500 for 1-1⁄2" thick). 10. Start the conveyor, stand to the side as shown in Figure 29, and feed the workpiece into the sander. 4. Press and hold the SET key for 3 seconds: The table is now calibrated. 5. Press the down arrow key: 11. Observe the load meter, and press the table down arrow key on the key pad to reduce the sanding depth if there is a problem. 6. Remove the calibration board.
MAINTENANCE TURN-OFF and LOCK your master power switch when performing maintenance, so no power is available to the sander! If you ignore this warning serious electrical shock may occur causing injury or death! General Figure 30. Conveyor speed change. Regular maintenance on your Model W1709 will ensure its optimum performance. Make a habit of inspecting your machine each time you use it. And at the end of the day remove the sanding belt and clean the back side of the sanding belt and the drums.
• After every 20-40 hours of use, lubricate the elevation screws, chains, sprockets, and the table guides under the table with a light coating of white lithium grease. See Figure 32. Chain Cleaning Belts To increase working life of your sanding belts, we recommend that you routinely clean them with a Pro-Stik® Cleaning Pad shown in Figure 33. Sprocket Elevation Screw To clean the belts, simply set your table to the thickness of the cleaning pad and run the pad through the sander two or three times.
Servicing Brake Rotor Any grease or oil on the emergency brake rotor creates the potential for reduced emergency braking ability. Check the brake rotor (shown in Figure 35) regularly to make sure it is clean. If it needs cleaning, only use automotive brake parts cleaner and a dry rag. DO NOT use water! Retaining Nut Anchor Pins The brake pads shown in Figure 36 will eventually need to be replaced. To check the condition of the brake pads, do these steps: 1.
Changing V-Belts Check the V-belts periodically to check for signs of glazing, cracking or fraying. If any of these conditions are present, change both Vbelts. To change the V-belts, do these steps: 1. TURN-OFF and LOCK the master power switch so no power can go to your sander and shut off the air pressure! 2. Open both right-side upper and lower access covers. 3. Remove the two screws and the safety cover for access to the upper pulley. See Figures 37. 4. Figure 37. Upper pulley exposed.
Troubleshooting SYMPTOM HOW TO REMEDY Motor will not start; fuses or circuit breakers blow. 1. Low voltage. 2. Open circuit in motor or loose or shorted connections. 3. Short circuit in motor or loose connections. 4. Incorrect fuses or circuit breakers. 5. Faulty start capacitor. 6. Faulty motor. Check power line for proper voltage. Inspect all lead connections on motor for loose, shorted, or open connections and replace or repair.
