[2] How to Apply Grease
Apply grease through gaps along the top cover.
1) Turn the opening/closing screw with a screwdriver to move the fingers toward their homes.
2) Spray grease toward the worm gears through gaps along the top cover. (Do not spray more than 1
second on the left and right.)
3) Turn the opening/closing screw using a screwdriver to move the fingers in the directions opposite
their homes (toward the stroke center).
4) Spray grease in the same manner as in 2).
5) After grease has been applied, turn the opening/closing screw to move the fingers back and forth
several times to spread the grease evenly
Caution:
• Never use fluorine grease. If fluorine grease is mi xed with lithium grease, the lubricating function
of grease will drop and the machine may suffer damage due to increased friction.
• Do not use spray oil. Be sure to use spray grease. Keep the spray time to a maximum of 1
second, and never spray more than once. If too much grease is applied, excess grease may flow
into the electronic components and cause malfunction.
• In case the grease got into your eye, immediat ely go to see the doctor to get an appropriate care.
After finishing the grease supply work, wash your hands carefully with water and soap to rinse the
grease off.
