11.5 Interior Inspection
Turn off the power, remove the side covers, and then visually inspect the interior.
Check the following items during interior inspection.
Internal check points
Body Loose mounting bolts?
Guides Lubrication appropriate? Soiling?
Ball screw Lubrication appropriate? Soiling?
1) Remove both side covers.
Use an Allen wrench of 1.5 mm across flats.
2) If the grease becomes dirty and dull or if the grease has worn away due to extended operating time, lubricate
the parts after cleaning them.
3) When the inspection/maintenance work is complete, install the side covers.

Caution:

When checking the interior, be careful not to bend or scratch the stainless sheet. Wear
protective gloves when handling the stainless sheet, because it has sharp edges that
may cause accidental cuts.
The front cover is supporting the ball screw; so do not disassemble the front cover.
If the front cover is misaligned, the shaft centers may become offset, thus increasing the
traveling resistance, reducing the service life of each part, or generating noise.

If the actuator is equipped with a microswitch (optional), carefully install the side covers
so that the switch cables are not pinched.
Make a visual check of the interior to see if there is any
dust or foreign matter in the unit and check the
lubrication. Even if the grease you see around the parts
is brown, the lubrication is fine as long as the traveling
surface appears shiny.
When installing the side covers, do not let them contact
the end faces of the stainless sheet. It may damage or
bend the stainless sheet, causing the sheet to
deteriorate or wear quickly. To prevent this problem,
insert a shim (approx. 0.1 to 0.2 mm) between the
sheet and each cover to provide an allowance, and
gently push in the cover.
