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 tool, check that the handle is tightened securely.

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.
