⑦ Remove any dirt such as dust, etc., by washing
removed components.
⑧ Apply grease sparingly to the outer circumference of
the slider
[D] and the inner circumference of the
main unit. [H] (Too much grease may influence
movement of the slider at low loads.)
⑨ Install the spring washer [J] [K] , spring [I] , and
slider [D] into the main unit [H] , then install the
roller screws [E] , collars [F] , and guide rollers
[G] (2 locations).
⑩ Install the bush [C] into the slider [D] and set
the set screws [B] .
