D. Position powerside columns
Lay down two columns on the installation site parallelly, position the powerside
column according to the actual installation site. Usually, it is suggested to install
powerside column on the front-right side from which vehicles are driven to the
lift .Then install the top plates.
(See Fig. 12).
