EXTENSION CORD SELECTION If an extension cord is used, make sure the conductor size is large enough to prevent excessive voltage drop which will cause loss of power and possible motor damage. A table of recommended extension cord sizes will be found in this section. This table is based on limiting line voltage drop to 5 volts (10 volts for 230 volts) at 150% of rated amperes. If an extension cord is to be used outdoors it must be marked with the suffix W-A or W following the cord type designation.

Rotate the guard to a position that will place the guard between the operator and the grinding wheel (or any other accessory requiring a guard). Tighten the clamp screw (A) Fig. 3A to secure the guard in proper position (see Fig. 4). Always make sure that the wheel guard is positioned between the operator and the wheel, so that flying chips or pieces of a wheel that might break will be deflected away from the operator (see Fig. 4).
OPERATION USING A DISC GRINDER Be certain that the wheel guard and auxiliary handle are installed. Firmly grip the auxiliary handle and motor housing (Fig. 8). Lift up the rear of the motor housing so that only the front section of the grinding wheel contacts the work. Use light pressure. Always lift the grinder off the work before starting or stopping the motor. The arrow on the front gear housing indicates the direction in which the grinding wheel rotates. Fig.
