NEVER assemble a grinding wheel on the

arbor without paper or fiber discs between

the wheel and the flange. Not using the

discs can put stress on the wheel, causing

it to crack and possibly fall apart.

ALWAYS visually inspect and perform a

“ring test” on a wheel before assembly. DO

NOT use damaged wheels!

6. Re-install the wheel guard.

7. Run a new wheel for at least one minute

while standing clear of the line of rotation. If
a wheel does have defects it will generally fail
within that time.

Wheel Replacement

The wheel guard must be removed in order to
mount or dismount a grinding wheel.

To replace a grinding wheel:

1. UNPLUG THE GRINDER!

2. Remove the wheel guard.

3. Use a wrench on the arbor nut. Hold the

wheel from turning with your other hand.
Note that the wheel on the left-hand side of
the machine has left-handed threads, so the
arbor nut on that side must be turned clock-
wise to loosen.

4. Remove the outer wheel flange and the

paper disc. Pull the wheel free from the
arbor. There will also be a paper disc and a
wheel flange on the other side of the wheel.

5. Mount the new wheel as shown in Figure

7.  Always  make  certain  there  is  a  paper  or
fiber  disc  between  the  wheel  flanges  and
the  wheel  itself.  Tighten  the  nut  snugly  but
DO NOT  over-tighten.  Over-tightening  can
crack the wheel (see

Figure 8).
