Adjusting the Screw Height
We know the H
screw height
is 236 mm from the previous example. So, we will move the screw
from the default (current) position to the new one.
1. Loosen two bolts halfway (important!) .
DO NOT unscrew completely the bolt. If not, it could drop
into the column and may cause big trouble to retrieve it out.
2. Looking up the scale, slide the Limit Block down to a new location (H
screw height =
236
mm) and fix it back.
3. Put the covers back in reverse order and fix them with the bolts.
