13. Maintenance and Inspection
13.4.2 Short types
When inspecting the interior, check the items specified below.
Main unit
Loose bolts, other loose items
Slid screw/guide rail
Lubrication, buildup
[Internal inspection of slide screw]
To check the slide screw or ball screw, turn off the power, extend the table, and pull the narrower end of
the spiral cover toward the wider end (in the direction of the arrow) to expose the screw shaft and inspect
the shaft visually.
If the lead is too small and the table does not move, insert a slotted screwdriver, etc., into the cutout
groove provided in the shaft on the rear side and turn. [Refer to 11.4, “How to Move Table by Hand.”]
Visually check the lubrication condition of the slide screw or ball screw.
Even when the grease is brown, the screw is lubricated property as long as the traveling surface looks wet
and shining. 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 grease.
