1 INTRODUCTION
This guide has been made to supply the owner as well the user with the basic
instructions for a correct use of the machine. Read this guide carefully before using
the machine and following the instructions given by this guide to grant the machine a
correct function, efficiency and a long service life
The electro/hydraulic lift is composed by two symmetric vertical columns which must
be safety anchored at ground. Trolley is equipped inside each column.
The lift is operated by an electric motor controlling a hydraulic pump, which delivers
the hydraulic fluid to cylinders inside the columns for lifting two trolleys.
The 2-post lift is suitable for lifting motor vehicles having maximum weight as
described below: any other use is to be considered improper and irrational and thus
highly forbidden. the constructor cannot be held responsibilities for any damage or
injuries caused by an improper use or the non-observance of the following
instructions:
