Wheel Balancing; Grounding Instructions - Jet JPSG-618M1 Operating Instructions And Parts Manual

Wheel Balancing

1. Attach the wheel to the surface grinder.
2. Turn on the surface grinder and then turn on
coolant flow.
3. Dress the wheel (see instructions above).
4. Remove the dresser, turn off the coolant
and dry-run the wheel for ten minutes to
remove any coolant.
5. Turn off the surface grinder and disconnect
the machine from power source.
6. Remove the center nut and pull the wheel
assembly off the shaft using the wheel
extractor. Wipe out the inside of the wheel
assembly.
7. Wipe off the balancing arbor and insert it
into the wheel assembly.
8. Place the wheel assembly on the balancing
stand (Figure 10) and mark its gravity center
"S" with chalk. See Figure 11.
9. Insert a balancing weight "G" directly
opposite of gravity center "S" (Figure 11).
10. Determine which side is heavier, "G" or "S".
11. Insert two balancing weights "K" on the
lighter side. If the wheel is still out of
balance, adjust "K" for balance. See Figure
11.
12. After balancing, do a final dressing of the
grinding wheel.

This machine must be grounded. In the event of
a malfunction or breakdown, grounding provides
a path of least resistance for electric current to
reduce the risk of electric shock.
