(4) Ensure the clearance between the caster and the floor by approximately 2.5 mm when the height
adjustment is performed. (One revolution of screw jack = 2.5 mm)
Caution of Over-Turning/Jammed Connecting Bolts:
Work carefully for the height adjustment. A lack of balance that only one part rises too much
causes the over-turning. The height of the screw jacks shall be adjusted in 1/4 rotations evenly
into the four places in order. Failure to do this may put too much stress on the connecting bolts
and jam the bolts, making it impossible to remove them in the worst case scenario.
Caution of Breakage:
This equipment is very heavy and applies pressure to screw jacks. If you fail to jack up the
equipment by rotating the four screw jacks in 1/4 turn increments evenly, the screw jacks may
jam and be broken.
