Read the manual before operation.
Become familiar with this tool, its
safety instructions, and its operation
before beginning any work. Serious
personal injury may result if safety
or operational information is not

Installing Bits
The Model H8212 uses bits and cutters

for a complete
listing of available bits and accessories.

under the stresses of high speed use
causing serious personal injury.
To install a bit:
1.
DISCONNECT THE GRINDER FROM
THE AIR SUPPLY!
2.
Use the two included wrenches
to loos-
en the collet nut, as shown in
Figure

.
Note:
It is not necessary to completely
remove the collet nut from the shaft
unless you are replacing the collet.
3.
Insert at least
1
⁄
2
" of the bit into the
collet.
4.
Use the collet wrenches to tighten the
collet nut. Verify that the tooling bit is
secure and will not pull out.
