4.4 Inside Visual Inspection
Turn the power OFF and have a visual inspection.
Conduct the item below in the internal inspection.
䎃
Main Body Looseness of attachment screws
Guide Part Condition and dirt of lubricant
䎃
Detach the seals and ball screw guide by following the procedures described below so you can see the
guiding area to visually inspect the condition inside. In the inspection, it should be checked if dust is
involved inside and the condition of the lubricant.
Even if the grease looks brown, it will be fine as long as the sliding area seems wet and shiny.
If the grease is mixed with dust and dirty or has no shiny appearance, or if the grease has lost its
efficacy due to prolonged use, clean the applicable area and then replenish the grease.
Described below is how to check inside.

(at the circled places) with a hex wrench to detach the cover.
