B．SPECIFICATIONS OF CONCRETE
Specifications of concrete must be adhered to the specification as following.
Failure to do so may result in lift and/or vehicle falling.
1．Concrete must be thickness 5-7/8’’ minimum and without reinforcing steel bars， and
must be dried completely before the installation.
2．Concrete must be in good condition and must be of test strength 3,000psi
(210kg/cm²) minimum.
3．Floors must be level and no cracks.
C．POWER SUPPLY
The electrical source must be 3.0KW minimum. The source cable size must be
2.5mm² and in good condition of contacting with floor.
III. STEPS OF INSTALLATION
A. Location of Installation
Check and insure the installation location (concrete, layout, space size etc.) is
suitable for lift installation.
1. For Standard Installation: On surface installation

E. Adjust Photo cell device and level two platforms
1. Remove the cover of photo cell device on off-side platform firstly. (See Fig.22)
2. Check by level bar and adjust the lower leveling bolts(See Fig.23), use the shims to
adjust the platforms until the front and rear of two platforms are in the same level.
Adjust the Upper leveling bolts(See Fig.24) after it touch the Lower leveling bolts
when lower to the lowest position. Then Tighten nut by wrench.
