H3117 Mini Grinder
-4-
OPERATION
Installing Bits
The Model H3117 can use most bits and
cutters that have a
1
⁄8" diameter shaft. See
the Grizzly catalog or website for a com-
plete listing of available bits and acces-
sories.
To install a bit:
1. Unplug the tool from the power
source!
2. Depress the Collet Lock. The Collet
Lock is a small black button near the ip
of the Grinder. Initially the Collet Lock
may not depress when pushed; how-
ever, continue to apply and hold pres-
sure on the Collet Lock.
3. While applying pressure to the Collet
Lock, use your other hand to rotate the
Collet Nut and loosen it. At some point
through the rotation the Collet Lock will
engage, preventing further rotation of
the Collet Nut.
4. With the Collet Lock engaged, the
Collet Nut should easily loosen and
unthread by hand. DO NOT complete-
ly remove the Collet Nut from the shaft.
5. Insert the end of a bit into the Collet. At
least
1
⁄2" of the bit shaft should be
mounted into the end of the Collet.
6. While depressing the Collet Lock,
rotate the Collet Nut to secure the bit.
Only hand tighten the bit. Excessive
tightening with the Collet Wrench is not
necessary.
Before Start Up
1. Be sure the bit and the Collet Nut are
secure on the grinder shaft.
2. Wear safety glasses and a dust mask
when operating the grinder.
3. Turn the Power Switch to the OFF “—”
position.
4. Plug the grinder into the power source.
DO NOT use bits or cutters with a
cutting surface larger than 1" in
diameter. The bit could break apart
under the stresses of high speed use
causing serious personal injury.
