SAFETYOPERATIONMAINTENANCE SETUP
12. Thread the Outer Flange onto the Spindle.
Wrench tighten 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.
Operating LED Lights
1. To operate LED lights, insert two AAA
batteries into the battery compartment.
2. Close battery compartment and
press LED power button.
NOTICE: Do not mix old and new batteries. Do not
mix alkaline, standard (carbon-zinc), or rechargeable
(nickel-cadmium) batteries. Position batteries in proper
polarity. Do not use swollen or leaking batteries.
Correcting Wheel Balance
Confirm Wheel balance by spinning the Wheel by
hand and observing the Wheel distance from the
Tool Rest as it spins; variations in this distance
indicates the Wheel balance needs to be corrected:
1. Loosen Nut, and manually (if possible) adjust
the Wheel closer to the Arbor centerline;
hold in place while tightening the Nut.
2. Use a Wheel Dresser to remove the outermost
layer and / or high spots of the Grinding Wheel
to achieve Wheel balance. Follow the Wheel
Dresser Manufacturer’s instructions.
Note: If Wheel still vibrates excessively after the
Wheel has been dressed or adjusted to center
as described above, and Wheel does not exhibit
wobble from side to side at speed, Wheel is
likely out of balance and should be replaced.
Eliminating Wheel Wobble (Side to Side)
Note: Slight side to side wobble may exist as the
Wheel spins up or down from full speed, but this will
not affect normal operation. Follow the instructions
below to remove excessive side to side wobble:
1. Loosen Nut and rotate Outer Flange slightly.
Snug the Nut and rotate the Wheel by
hand to confirm wobble is eliminated.
2. If Wobble still exists, continue repeating step 1 in
slight increments in the same direction, making sure
Wheel is in the same orientation as it was in step 1.
3. If Wobble is still not eliminated, continue holding
Wheel in same orientation as it was in step
1, and rotate Inner Flange 90
o
. Repeat Steps
1-2. Continue this sequence of Inner and Outer
Flange movements until Wobble is eliminated.
Note: If necessary, a shim made of paper / card
stock may be placed between the Inner or Outer
Flange and Wheel. If excessive Wobble still
exists, consult ″Troubleshooting″ on page 12,
remembering these possible sources of imbalance:
• Wheel is not balanced or is out-of-round.
• Wheel Arbor bushing has excessive play.
• Wheel is of poor quality.
• Inner or Outer Flanges are warped.
