Lock Nut and Backing Flange
(Fig. 6)
Your tool is equipped with a threaded Spindle
18 for mounting ac ces sories. Always use the
supplied Quick-Clamping Nut 10 or the original
BOSCH Lock Nut 21 (which you can buy sepa-
rately), and backing flange, that has the same
thread size as the Spindle 18. The Backing
Flange 19 is keyed to the Spindle 18. If you use
the original BOSCH Lock Nut 21, always make
sure that the lock nut is tightened correctly
with a compatible lock nut wrench.

To Attach Grinding Wheel
(Fig. 1, Fig. 2, Fig. 5, Fig. 6, Fig. 7)
1. Disconnect the Battery Pack 5 from the
tool.
2. Be sure that the Type B (27) Wheel Guard
9 is in place for grinding.
3. Place the Backing Flange 19 and Type 27
Grinding Wheel 11 on the Spindle 18.
Make sure the Backing Flange 19 locks into
the base of the Spindle 18.
4. Thread on the Quick-Clamping Nut 10, and
tighten the nut using the Fold-Up Bar 17,
while holding the Spindle Lock 1. (You can
also use an original BOSCH Lock Nut 21,
sold separately.)
TO REMOVE: Reverse the procedure.
When Using Spin-On Wheels
(Fig. 6, Fig. 7)
Follow steps 1 and 2 in "To Attach Grind-
ing Wheel," then thread the Type 27 Spin-On
Grinding Wheel 20 directly onto the Spindle
18 without using the supplied flanges. Always
make sure that the Spin-On Grinding Wheel 20
is tightened correctly with an open-end wrench
(not supplied).
TO REMOVE: Reverse procedure.
All parts of a Type 27 Spin-On Grinding Wheel
20 must be within the Lip of the Wheel Guard
22. If the Spin-On Grinding Wheel 20 is past
the lip of the Wheel Guard 22, do not use that
wheel as it does not fit on this grinder.
