Lock Nut and Backing Flange
Your tool is equipped with a threaded
spindle for mounting ac ces sories. Always
use the supplied quick-clamping nut or the
original BOSCH lock nut (which you can buy
separately), and backing flange, that has the
same thread size as the spindle. Backing
flange is keyed to output shaft (Fig. 3). If
you use the original lock nut, always make
sure that the lock nut is tightened correctly
with the supplied wrench.

spin-on wheel is tightened correctly with an
open-end wrench (not supplied).

All parts of a spin-on wheel must be within
lip of grinding guard (Fig. 4). If spin-on
wheel is past lip of guard, do not use that
wheel as it does not fit on this grinder.
The tool will vibrate excessively and may
cause loss of control and the accessory may
burst.
Do not use accessories
that run eccentrically.
