Model H8218 Mini Die Grinder-4-
OPERATIONS
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
understood or followed.
Installing Bits
The Model H8218 uses bits and cutters
with a
1
/4" diameter shaft. See the Grizzly
catalog or www.grizzly.com for a complete
listing of available bits and accessories.
DO NOT use bits or cutters with
a cutting diameter larger than 1".
The bit or cutter could break apart
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
2.
Note: It is not necessary to com-
pletely remove the collet nut from the
shaft unless you are also changing the
collet.
3. Insert at least
1
⁄2" of the bit into the
collet.
4. Hand tighten the collet nut, then use
the collet wrenches to tighten the collet
nut. Verify that the tooling bit is secure
and will not pull out.

Like all tools there is potential danger
when operating this tool. Accidents
are frequently caused by lack of
familiarity or failure to pay attention.
If normal safety precautions are
overlooked or ignored, serious
personal injury may occur.
