Instructions

1.Before use, first wipe the surface of storage battery, pulley, rubber belt, plexiglass cylinder, discharge ball, etc. (do not use wet cloth) to ensure that the surface can not have metal shavings or moisture.
2.Adjust the tightening bolts of the pulley until it is tight and rotate properly. If the pulley does not rotate, loosen the bolt.
3.The collector comb is as close to the rubber wheel as possible, but it cannot be touched.
4.Connect the discharge ball wire to the grounding bolt and tighten it.
5.Remove the upper half of the storage ball and try a few minutes. If the climate is relatively humid, turn on the incandescent light switch to remove the moisture and use it.
6.Because the instrument is a high-voltage device, the teacher or parents are required to guide and care at the time of the experiment, and the child should not be allowed to operate and use it.

Maintenance and Preservation

1. Relax the pulley after use to increase its lifespan of the pulley.
2. Pack the instrument and store it in a dry, dust-free place.
3. If you are using it at home, lock the instrument to prevent it from being touched by the child.
4. Handle with care.
