1. Assembling (Fig. 1) (1) Turn the grinder upsidedown so that the spindle is facing upward. (2) Mount the wheel washer onto the spindle. (3) Fit the protuberance of the depressed center wheel or diamond wheel onto the wheel washer. (4) Assemble the wheel nut onto the spindle. (For diamond wheel assembling, use the wheel nut with the convex side against the diamond wheel.) (5) Insert the push button to prevent rotation of the spindle, and tighten the wheel nut with accessory wrench, as shown in Fig. 1. 2. Disassembling Follow the above procedures in reverse. CAUTIONS: . Confirm that the grinder wheel is mounted firmly. . Confirm that the spindle lock mechanism is disengaged by pushing push button two or three times before switching the grinder on. MAINTENANCE AND INSPECTION 1. Inspecting the depressed center wheel Ensure that the depressed center wheel is free of 2. Inspecting the mounting screws Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be loosened, retighten them immediately. Failure to do so could result in serious hazard. 3. Inspecting the carbon brushes (Fig. 5) The Motor employs carbon brushes which are consumable parts. When they become worn to or near the “wear limit”, it could result in motor trouble. When an auto-shop carbon brush is equipped, the motor will stop automatically. At that time, replace both carbon brushes with new ones which have the same carbon brush Numbers shown in the figure. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders. 4. Replacing a carbon brush (Fig. 6) (1) Loosen the D4 tapping screw retaining the tail cover and remove the tail cover. (2) Use the auxiliary hexagonal wrench or small screwdriver to pull up the edge of the spring that is holding down the carbon brush. Remove the edge of the spring toward the outside of the brush holder. (3) Remove the end of the pig-tail of the carbon brush from the terminal section of brush holder and then remove the carbon brush from the brush holder. (1) Insert the end of the pig-tail of the carbon brush in the terminal section of brush holder. (2) Insert the carbon brush in the brush holder. (3) Use the auxiliary hexagonal wrench or small screwdriver to return the edge of the spring to the head of the carbon brush. (4) Mount the tail cover and tighten the D4 tapping screw. 5. Maintenance of the motor The motor unit winding is the very “heart” of the power tool. Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.
