The use of accessories not listed for a particular tool is not recommended and may be hazardous. To Install Sanding Discs: 1) Place Quick-Change Pad and sanding disc on spindle of tool. 2) Screw the Clamp Washer PARTIALLY onto the spindle. (Fig. 7). 3) Raise the pad and sanding disc so that the hexagonal exterior of the Clamp Washer engages the hexagonal hub of the Quick-Change Pad. 4) With one hand, depress the spindle lock button and hold the button in. Grasp the pad and sanding disc with the other hand, and turn by hand to tighten the entire assembly (Fig. 8). To remove pad and disc, turn pad and spindle i shown in Fig. 8 to engage Spindle Lock Button, and disc and turn the pad and disc assembly i direction. For maximum efficiency, the tool must be positioned so that the sanding disc is at the proper angle to the work. Fig. 9 (marked “RIGHT”) illustrates how the tool is tipped slightly in order to let the maximum amount of abrasive contact the work without'affecting the smoothness of the sanding action. Fig. 10 and Fig. 11 (marked “WRONG”) show incorrect positions which allow either too little or too much abrasive contact. If only the outer edge of the sanding disc is used (as in Fig. 10), a rough cut surface will result. If the sanding disc is pressed flat against the work (as in Fig. 11), the cutting action will be irregular and bumpy, and the tool will be difficult to control. Fig. 10 7 Fig. 11 OPERATION (Continued) GRINDING WITH DEPRESSED-CENTER GRINDING WHEELS Depressed Center Grinding Wheels may be used with the proper Guard Assembly for moderate metal removal on flat or contoured surfaces. CAUTION: See Page 6 for proper application of Depressed Center Grinding Wheels and Guards with your tool. The 8000 RPM Grinder uses ONLY Depressed Center Grinding Wheels rated at 8500 RPM and above (Cat. No. 52524). Use of wheels other than those listed on page 6 for a particular tool is not recommended and may be hazardous. Never use Depressed Center Grinding Wheels without the proper guard. To install Depressed Center Grinding Wheels: 1) Be sure tool is disconnected from power supply and switch is in “OFF” position. 2) Be sure that Guard Assembly is securely attached to the spindle housing. 3) Put the Backing Flange onto the tool spindle. 4) Check rated speed on Depressed Center Wheel. Never use wheel with rated speed lower than the speed on the nameplate of the tool. 5) Place the Depressed Center Wheel on the tool spindle. 6) Thread the Clamp Washer on tool spindle, engage Spindle Lock, and tighten Clamp Washer with Spanner Wrench. When using a Depressed Center Wheel, hold the tool so that an angle of 30° to 45° exists between the wheel and the work See Fig. 13. GRINDING WITH FLARING CUP GRINDING WHEELS Use Flaring Cup Wheels for heavy metal removal or on flat areas. A %"-ll thread bushing in the wheel threads directly on the Sander spindle. Flaring Cup Wheel Guards provide maximum safety when using Flaring Cup Wheels. Guard fits snugly over Wheel. Guard revolves with the Wheel and should be used only with threaded bushing type Wheels. CAUTION: See page 6 for proper application of Flaring Cup Wheels and Guards with your tool. The 8000 RPM Grinder uses ONLY Flaring Cup Wheels rated at 8500 RPM and above (Cat. No. 24050). Use of wheels other than those listed on page 6 for a particular tool is not recommended and may be hazardous. Never use Flaring Cup Wheels without the proper Guard. To attach Wheel and Guards: 1) Disconnect tool from power supply. 2) Check rated speed of Flaring Cup Wheel, Never use a wheel with rated speed lower than the speed on the tool nameplate. 3) Engage the Spindle Lock. 4) Thread Flaring Cup Wheel (with Wheel Guard) on the spindle. Be sure that wheel is firmly and completely threaded on spindle. 8 OPERATION (Continued) FLARING CUP GRINDING WHEELS (Cont.) When grinding, tilt tool slightly—do not hold Wheel perfectly flat against the work. Avoid bouncing the Wheel or giving it rough treatment, since cracks might develop which would cause the Wheel to fly apart. Always check the Wheel for cracks before using it, especially if tool may have been dropped. Always use a Wheel Guard. Fig. 14 USE OF WIRE CUP BRUSHES Use Wire Cup Brushes for removing rust, scale, old paint, etc. CAUTION: See page 6 for proper application of Wire Cup Brushes with your tool.
