(Arrange the adjuster so that it reaches the floor surface.)

Note
● The height is adjustable by the level adjusters of the floor unit up to 150 mm.
For adjustment exceeding 150 mm, provide a base of brick, block, and mortar, etc. inside of the reinforce-
ment frame to raise the level.
● For level adjustment of the corner adjuster, it is convenient to use a nut driver or a deep socket with the
distance across flats of 17 mm.
3. Fasten the Level Adjuster Nut.
※ Use a wrench to hold the adjuster and the cap nut in order to
prevent rotation of the adjuster while tightening the adjuster nut.
※ Make sure to fasten the central adjuster using the long nut
after completion of adjustment.
CAUTION
In the case of replacement with existing RS OASIS (use of the
mortar work form), adjust the central adjuster to reach the mortar
floor surface.
If the adjuster cannot reach the floor or the mortar surface is sandy,
lay bricks or blocks to make the adjuster reach it.
