8. Maintenance:
Warning
・
Before care and maintenance of the product, be sure to turn OFF the power and air. Otherwise damage or operating
problems may occur.
・
The tip of the discharge needle is sharp; be careful not to touch the discharge needle.
・
The electrodes gradually become deteriorated with exposure to alternating high-voltage electric fields. They must
be replaced periodically. The expected life span is thought to be 20,000 hours even if sufficient maintenance is
conducted, and replacement is recommended after 20,000 hours. If regular maintenance is not performed, the
life span of the 966-II will decrease. The maintenance is very important. Position the unit at a place where it is
free from water and oil, etc, It gets wet, dry it with a clean cloth.
・
Attachment of contamination to the tip of the discharge needle will deteriorate the static and elimination effect. If
deterioration of the static elimination effect is observed, clean the needle and its surrounding area using a nylon
brush etc. (Never use a wire brush for cleaning the needle.)
・
The discharge needle must be replaced periodically.
Replacing the discharge needle unit:
1. Use a screwdriver to rotate the knob at the rear of the discharge needle unit in a FREE (counterclockwise)
direction.
2. Pull down the discharge needle unit to the rear.
3. After cleaning the discharge needle, and installing the discharge needle to the main unit, rotate the locked
knob of the discharge needle unit in the LOCK direction (clockwise) until the locked knob is securely locked
with the main unit. Tightening torque is 8 to 10N
・
cm.
Caution
・
Clean the discharge needle periodically even if the Cleaning Check signal is not displayed.
(Recommended once every 2 weeks)
