Be sure to read and understand on the page 3 to 7 “For safety operation” carefully before use
Cleaning of the charging electrode
When dust or dirt accumulates about 2mm on the electrical charge poles (at any portion of them), when the
points of needles are contaminated and the performance cannot be maintained, or when an abnormal spark
frequently occurs irrespective of maintenance and the operation is shut down, clean it in the following
procedure: Follow the procedures up to the preceding section to open or close the inspection door and take
out the charging electrode.
●
1
Pulling out the charging electrode
Open the inspection door and pull out the charging electrode.
●
2
Putting the charging electrode in the
cleaning liquid
Pull out the charging electrode and put the cleaner for oil removal in
the container and soak the charging electrode for ten minutes. Put the
needle electrode face to downside when putting the charging
electrode in cleaning liquid.
If the contaminants are difficult to take off after immersing for 10
minutes, take the following procedure.
・
After immersing it for about two hours, do air blow to take off the
contaminants.
・
After immersing it all night, rinse it to take off the contaminants.
Caution
Examples
Caution: The level or status of
contamination of the needles

When holding the charging electrode by the hand, do not put fingers
on the ground board. If the fingers go around on the board, the points
of the electrical discharging needle may stick the fingers.
Caution
Do not hold it in a manner that your finger(s) comes in the hole of the ground board.
Hole of ground board
Put the top of wire electrode
facing down to the cleaning liquid.
