Helping you get the most out of your shop for the last 40 years. THE SAFE WAY IS THE ONLY WAY TO GRIND! Instructions given with this symbol are for personal safety. When using electric tools, basic safety precautions should always be followed to reduce the risk of fire, electric shock, and personal injury including the following. WARNING 1. Grounding Instructions - This tool must be grounded while in use to protect the operator from electric shock. The tool is equipped with an approved three conductor cord and three prong grounding type plug to fit the proper grounding type receptacle. [. . . ] The edge angle can be varied plus or minus the 30 degree reference point via the adjusting crank. Lowering the grinding wheel into the work table (grinding into the work table) will result in a greater than 30 degree angle (a steeper angle. ) Note, you will be creating a new angle reference point Raising the grinding wheel will result in a lesser than 30 degree angle (a more shallow angle. ) page 8 MAG-8000 Use Con't Step 7: Conventional Blades Blade & Sharpener Preparation 1. Clean the blade to its base material, using the MAG12000 blade cleaner, or alternate cleaning process. Check the straightness with the gauge rod of the MAG-1000 blade balancer. Obtain a balance reading from the MAG-1000 to indicate the light end of the lawn mower blade. The MAG-8000 will require the 1" inch wide grinding wheel to sharpen a conventional blade. (1/2" wide grinding wheel may be used for conventional blades) 5. The mobile work table will be needed to sharpen a conventional blade, slide the mobile work table over the curved 1/2" wide work table, and clamp it tight with the attached vice grip. Lower the grinding wheel with the adjustment crank, stop just before you grind the corner of the work table. When the grinding wheel is almost touching the corner of the work table (curved or mobile work tables) you will produce a 30 degree angle on the lawn mower blade. Place the conventional blade on the flat work table and pull and push the blade across the grinding wheel (perpendicular to the rotation of the grinding wheel, see page 10. ) Keep firm pressure downward on the blade to maintain contact with the surface of the work table. The force into the grinding wheel should be substantial, resulting in a continuous stream of sparks from the grinding wheel. The grinding process should be continuous without interruption until finished. 9 page The above diagram shows the application of movement and force to the blade during sharpening a conventional blade. Note, for curved edge mulching blades, it is the same except for the "forth" or inward fed motion. You will maintain much more control if you only "pull" mulching blades through the MAG-8000. Due to the "instant starting" of the MAG-8000 it has a tremendous starting draw, therefore a minimum 20 amp circuit is required. To diagnose a ON/OFF switch problem, (unplug from power source. ) Open the square access panel below the switch, and disconnect the (2) wires from the switch (label the wires before disconnecting. ) Directly connect and insulate the (2) wires. Plug the MAG-8000 into a power source, this should start the motor without the switch. If the MAG-9000 still does not start after this test, the solid state switch, capacitors, or the motor is no longer functioning and must be replaced. This is caused by a grinding wheel that is "out-of-round" or "out-of-balance" - this will happen when the user does not apply downward pressure on the blade when sliding it back and forth in the MAG-8000. Also, on occasion, grinding wheels can have a "hard spot" which will also cause this. [. . . ] Plug the MAG-9000 into a power source, this should start the motor without the switch. The third "red or blue" wire is only for the switch's light [MAG-9000 sharpeners with the metal toggle switch do not have this wire because there is no light. ] If the MAG-9000 still does not start after this test, the capacitor or the motor is no longer functioning and must be replaced. (SEE WIRING DIAGRAM PAGE 22) Call 800-328-1110 for replacement parts or a warranty issue. This is caused by a grinding wheel that is "out-of-round" or "out-of-balance" - this will happen when the operator does not apply downward pressure on the blade when sliding it back and forth in the MAG-9000.
