Step 1. Measure whether the height
of the left column and the right
column are the same using a
measuring tape before installation
Step 2. If the height of left column
is lower than the right column, insert
the transmission rod into the
hexagonal hole of the left column,
then rotate the transmission rod
anticlockwise to fine-tune the left
column to make the left column as
high as the right column
Step 3. If the height of the left column is
higher than the right column, insert the
transmission rod into the hexagonal hole of
the left column and rotate the transmission
rod clockwise to fine-tune the left column
to make the left column as high as the right
column
