Chicago Electric 66876 Set Up And Operating Instructions Manual page 15

Keep the Inner Flange (23) in position
on the Spindle.
note: The Inner Flange is always seated
so that the slotted side locks in place
on the Spindle, and the raised ridge
side is facing the Wheel.
4. Closely inspect the Grinding Wheel
(18) before mounting. Perform a
ring-test on the wheel (unless wheel
is smaller than 4" or is an unusual
shape) as follows:
Hang

a. Suspend wheel using a pin or finger
through the arbor hole.
b. Tap the flat side of the wheel with a
light non-metallic object, such as a
screwdriver handle, at a point 45°
from the vertical center line on each
side of the wheel and 1 – 2 inches
from the edge of the wheel - See
Figure 6.
c. Rotate the wheel 45 degrees and
repeat the test until the entire wheel
has been checked.
d. An undamaged wheel will give a
clear tone. If cracked, there will be a
dead sound and not a clear ring.

5. Slip the Wheel onto the Spindle. For
wheels with paper gaskets (blotters)
or metal gaskets: Slip the grind-
ing wheel onto the Spindle with the
gasket first. The gasket should be
centered on the grinding wheel and
the wheel and gasket should rest flat
against the Inner Flange.
warning: to prevent serious
injury, gaskets must be used for all
grinding wheels they are provided
with. gaskets help prevent grind-
ing wheel damage and wheel slip-
page, causes of wheel failure.
6. Position the Outer Flange (17) back
onto the Spindle.
note: For Wheels thicker than 3/16" thick,
put the Outer Flange on, raised
side first, so that the raised ridge
fits into the Wheel's hole. For thin-
ner Wheels, put the Outer Flange on
so that the indented side faces the
Wheel.
7. Tighten with the Spanner only
enough so that the wheel is securely
held on the spindle.
warning: to prevent serious
injury, do not overtighten flange.
overtightening can damage the
wheel, causing wheel failure.
installing a threaded accessory
wear heavy-duty work gloves
when handling saw blades.
these accessories are sharp
and can cause injury.
1. The accessory MUST be:
• rated to more than 6,500 RPM.
• no larger than 4-1/2" in diameter.
