Interior Inspection

Turn off the power, remove the side covers, and then visually inspect the interior.
Check the following items during interior inspection.
Body Loose mounting bolts?
Guides Lubrication appropriate? Soiling?
Ball screw Lubrication appropriate? Soiling?
How to inspect the interior:
1) Remove both side covers.
Use an Allen wrench of 1.5mm across flats for SA5C/SA6C/SA7C/SS7C or an Allen wrench of 2.00mm across
flats for SS8C/HS8C.
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.
Tightening torque: SA5C/SA6C/SA7C/SS7C:
SS8C/HS8C:
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.

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.

Thin-head screw M4 × 6 - 204 N·cm (20.8 kgf·cm)
When installing the side covers, do not let them contact the
end faces of the stainless sheet. This 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
0.2mm) between the sheet and each cover between the
sheet and each cover to provide a slight allowance, and
gently push in the cover.
