Low-dust-raising urea grease is used.
The following blends of grease are charged before shipment from IAI.

Grease Supply Method
Remove the two pan head machine screws on both sides of the slider cover to access a total of three
grease nipples. Use these grease nipples to add grease. As you see the grease nipples from the front side
of the actuator, those on the right are used to grease the guides, while the one on the left is used to grease
the ball screw shaft. (The grease nipples for guides are located on both sides of the slider, while the grease
nipple for ball screw shaft is provided on the left side as viewed from above the actuator with the motor
facing toward you.)
[1]
Remove the two pan head machine screws on the side faces of the slider cover to remove the cover.
[2]
Squirt grease in using a grease run. Repeat a pumping action three times at each grease nipple. (See
the figure below for the positions.)
[3]
Install the cover and put the two pan head machine screws back to reverse the step in [1].

Warning:
If your actuator is of cleanroom type, use low-dust-raising grease. If standard grease is
used, dust may be raised.
Never use fluorine or lithium grease. If fluorine or lithium grease is mixed with urea grease,
the lubrication performance normally expected from urea grease may be lost and
consequently the mechanical parts may be damaged or cleanliness may drop.

In case the grease got into your eye, immediately 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.
Charging too much grease may increase the agitation resistance and the ball screw may
generate heat easily, or excess grease attached to the ball screw may scatter due to
rotation of the ball screw to dirty the surrounding areas. To prevent these problems,
avoid adding too much grease. Also remember to wipe off excess grease.
