rear part of the switch to ensure that the tool is off.
ATTACHING SIDE HANDLE
The side handle can be fitted to either side of the gear
case in the threaded holes, as shown. Before using the

ACCESSORIES
It is important to choose the correct guards, backing
pads and flanges to use with grinder accessories. See
pages 5–6 for information on choosing the correct
accessories.
CAUTION: Accessories must be rated for at least the speed
recommended on the tool warning label. Wheels and other acces-
sories running over their rated speed may fly apart and cause
injury. Threaded accessories must have a 5/8" – 11 hub. Every
unthreaded accessory must have a 7/8" arbor hole. If it does not, it
may have been designed for a circular saw. Use only the acces-
sories shown on pages 5–6 of this manual. Accessory ratings must
always be above listed tool speed as shown on tool nameplate.
OPERATION

CAUTION: Check that the tool is not locked ON before connect-
ing it to a power supply. If the trigger switch is locked ON when the
