1) Move the rod in advance with such as JOG operation to get it in the position where the distance between the
end of the stopper spacer and the end of the aluminum flame is approximately 10mm.䎃
2) Turn the power off.䎃
3) Move the urethane stopper to the body end. (the urethane stopper can be moved with hand.)
4) A hole for grease supply can be seen in the rod.䎃
5) Remove the hex socket head cap screw that covers the grease supply hole with a 1.5mm-sized hex wrench.䎃
6) Insert the nozzle of the grease spray to the grease supply hole and spray it. The time to spray should be 1
second at maximum.䎃
7) Tighten the hex socket head cap screw to the rod with a 1.5mm-sized wrench, and move the urethane
stopper to the stopper spacer end.䎃
8) Push the rod firmly against the mechanical stopper on the other side of the home position (the side that the
rod comes out).䎃
9) Move the rod to the stroke range.䎃
10) Turn the power on, and run the rod back and forth for several times with such as JOG operation so the
grease spreads out to the whole area of the ball screw.䎃

Caution: x Do not use an oil spray when in grease supply. Make sure to use a grease spray.䎃
Time to spray should be 1 second at maximum. Do not attempt to spray more than 1 second in
one shot, or spray 2 times or more at once. Excessive grease supply may cause the oil flow to
the electrical components, which may lead to an unexpected operation.
x In case the grease got into your eye, immediately go see the doctor to get appropriate care.
After finishing the grease supply work, wash your hands carefully with water and soap to rinse
the grease off.
