10.4 Internal Check (Slider Type)
[1] With the SA6 and SA7, the screw cover and side
covers can be removed using a hex wrench with
1.5 mm width across flats.
 The front and rear brackets are supporting the ball
screw, so do not disassemble these brackets.
 Precision instrument is assembled into the motor
cover, so do not disassemble the motor cover.
[2] Visually check the internal condition. Check for
intrusion of dust and other foreign object, and also
check the lubrication condition. Even when the
grease is brown, the sliding surface is lubricated
properly if the surface looks wet and glowing.
Warning: The encoder phase is adjusted precisely to enable detection of rotation angle and
home signal. Never touch the encoder, since it may cause a breakdown.
[3] If the grease is contaminated with dust and not glowing, or if the grease has been consumed over a long
period of use, apply grease after cleaning the respective parts.
[4] When the inspection/maintenance is complete, install the side covers, stainless sheet and slider cover by
reversing the procedure in step [1] above. The tightening torque should be around the level applicable for
cross-recessed screws.
