Usage/Safety

General safety instructions for power tools (from this machine's manual)

  1. Know your power tool (read and understand the owner's manual before using and understand the specific hazards)
  2. Ground all tools (use grounded 3-prong plug inserted into proper grounding type receptacle)
  3. Keep guards in place (and in working order with proper adjustment and alignment)
  4. Remove adjusting keys and wrenches (form habit to check they are removed from tool before turning on the machine)
  5. Keep work area clean (cluttered areas and benches invite accidents and floor may be slippery due to sawdust)
  6. Avoid dangerous environment (don't use power tools in damp or wet locations, keep work area well lighted)
  7. Keep children away (all visitors should be kept at a safe distance)
  8. Make workshop kid-proof (consider padlocks, master switches and/or starter keys)
  9. Dont force tool (it will do the job better and safer at the rate for which it was designed)
  10. Use right tool (don't force the tool or attachment to do a job it was not designed for)
  11. Wear proper apparel (don't wear loose clothing, gloves, neckties, or jewelry, contain long hair, roll-up sleeves above the elbow)
  12. Use safety goggles (must comply with ANSI Z87.1, use face or dust mask and ear protection during extended periods of usage)
  13. Secure work (use clamps or a vice to hold work when practical as it is safer than using your hand)
  14. Don't overreach (keep proper footing and balance at all times)
  15. Maintain tools with care (keep tools sharp and clean for best and safest performance)
  16. Disconnect tools (before servicing when changing accessories, belts, and disks)
  17. Avoid accidental starting (make sure switch in in "OFF" position before plugging in)
  18. Use recommended accessories (consult the manual for recommended accessories, follow instructions, improper accessories may cause hazards)
  19. Never stand on tool (serious injury could occur if the tool is tipped or if the cutting tool is accidentally contacted)
  20. Check damaged parts (a damaged guard should be checked for proper function, check alignment of moving parts, binding, breakage, etc.)
  21. Direction of feed (feed work into a blade or cutter against the direction of rotation of the blade or cutter only)
  22. Never leave tool running unattended (turn power off and don't leave the tool until it comes to a complete stop)

Changing the Sanding Belt

  1. Use a shop vac to alternately vacuum and blow air inside the pulleys, along the top and bottom of the sanding table, pulley mounts, and the machine frame to clean away all sanding dust before proceeding
  2. Use the two included stamped 1/2" wrenches to loosen tension and adjust the idler pulley in to free the worn belt
  3. Slide the worn belt off the machine
  4. install the new belt on the machine. Pay attention to direction marked on belt.
  5. Use the two included stamped 1/2" wrenches to adjust the idler pulley out to initially tension the belt
  6. Jog the power and observe if the belt tracks left or right and adjust the left or right side as necessary to cause the belt to track straight
  7. It may take some fiddling and some time to get the belt seated to track on center without wandering left or right off of the pulley

Changing the Sanding Disk

  1. Use one of the 1/2" stamped wrenches to first remove the table (if present at the disk) by loosening its positioning screw
  2. Use a shop vac to alternately vacuum and blow air around the sanding disk, disk guarding, V-belt guarding and the machine frame to clean away all sanding dust before proceeding
  3. Use a flat blade screwdriver to loosen the screws holding the disk guard in place noting that most screw holes are slotted so the guard swings away for access to the worn sanding disk
  4. Pick at a spot on the circumference of the worn sanding disk to separate it from the metal disk and then fully peel the adhesive-mounted worn sanding disk from the metal disk
  5. Use a sharpie to write the yyyy-mm-dd exchange date on the inside (adhesive side) of the worn sanding disk and add it to the historic collection
  6. Use a liberal amount of acetone on a clean paper towel to remove all adhesive bugger residue from the metal disk until the metal disk is smooth and not tacky
  7. Use a sharpie to write the yyyy-mm-dd "installed new" date and "removed" text on the inside (adhesive side) of the new sanding disk
  8. Take the new sanding disk outside and spray a full coat of 3M Spray Adhesive to the felt side of the new sanding disk
  9. Bring the new sanding disk back to the machine and when the wet adhesive dries to be tacky, carefully center the sanding disk and adhere it to the metal disk without creases or bubbles
  10. Apply even hand pressure to assure smooth and full adhesion of the new sanding disk to the metal disk
  11. Swing the disk guard back into position on the mounting screws and tighten all screws
  12. Reinstall the table with a nominal 1/16" gap to the surface of the new sanding disk
  13. Power on the machine and use a scrap of wood to do a quick/light sanding test to observe an even pattern of sanding dust residue on the new sanding disk showing no high or low spots
