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. Be sure you and your employees follow them. A careful operator is the best insurance against accidents. Before handling any equipment read and understand the instructions. [. . . ] Allow the work table to follow the contours of the mulching blade. Use even pressure into the grinding wheel to achieve an even stream of sparks. 7 page MAG-8000 Use Con't Step 6: Con't 9. When using the MAG-8000 for mulching blades keep the blade level, and perpendicular to the rotation of the grinding wheel. Pay close attention to the TIP of the blade, see page 25. This view of the MAG-8000 (with the grit guard removed for visibility) you are able to see how the curved edge mulching blade should follow over the rounded work table. Contact between the blade and work table must be maintained Adjusting the Edge Angle Applies to both MAG-8000 and MAG-9000 30 Degree Reference Point - When the grinding wheel is lowered to the work table (almost cutting the work table corner) you will produce a 30 degree angle on the lawn mower blade. As the grinding wheel wears and reduces in diameter, continue to lower the grinding wheel to almost touch the work table to maintain a consistent 30 degree edge angle on a blade. 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. Once the light end is sharpened, it is complete. The heavy end is used to remove material for balance. SEE MAG-1000 Instruction Manual for more info on blade balancing. The MAG-8000 will require the 1" inch wide grinding wheel to sharpen a conventional blade. Mount the 1" wide grinding wheel on the MAG-8000. (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 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. Also, on occasion, grinding wheels can have a "hard spot" which will also cause this. [. . . ]
