C. POWER SUPPLY
The electrical source must be 110V. 20AMP breaker minimum is required. Electrical cord is
supplied with the 110V power unit. If a longer cord is needed to reach the electrical supply, use
only a commercial grade extension cord not exceeding 20 ft., or use a minimum 10 gauge cord

III. STEPS FOR INSTALLATION
A. Location of installation
Check the installation location (concrete, layout, space size etc.) is suitable for lift installation.
B. Check the parts before assembly
1. Packaged lift and Hydraulic Power Unit (See Fig. 4).
2. Open the outer packing carefully; check the parts according to the shipment list. (See Fig. 5).
Shipment Parts List
3. Remove the approach ramps and the four columns (See Fig. 6).
4. Loosen the screws on the upper package stand, remove the offside platform, take out the parts
inside the power side (cylinder) platform and remove the package stand.

7. Check the parts in the parts bag according to the parts bag list (See Fig. 9).
C. Install cross beams (See Fig.10, Fig.11).
Installation Note: For the operator’s convenience, the power unit may be installed on any of
the four corners. However, the power unit column (with motor bracket) and the power side platform
(with cylinder) must always stay together on the same side. Example: The power unit is positioned
on the driver’s front or rear (left front/left rear corner) and the power side (with cylinder) platform
must be installed the left side.

D. Install the Safety Ladders.
1. Remove the pulley covers and unscrew one nut from each of the safety lock ladders, and adjust
the four lower nuts to the same position. Install the safety ladders (See Fig. 12).

2. Install the Safety Lock Ladders (See Fig. 13).
E. Install the cross beams at the same height and lock on the safety lock ladders
(See Fig. 14).
This height should
be the same for all
four safety lock
ladders

F. Install the Power Side and Offside Platforms.
Note: Before installing the power side platform, pull the cylinder ram (not the whole cylinder) out
until it stops.
1. Install the power side platform on the cross beams by a fork lift or other lifting device, offset the
cross beams (spread opposite corners) to the outside until the pulleys on both platforms can
rest into the cross beams’ slots (See Fig.15), Install the power side platform and install the bolts
(See Fig.16). Do not tighten bolts until the offside platform is installed.
2. Pull the cross beams back together and install the offside platform.

3. Install wheel stop plates with bolts and washers on the platforms. Tighten the platforms on cross
beam B with bolts and washers. Tighten the wheel stop plates on cross beam Awith bolts and
washers
Note: The bolts for the wheel stop plates are longer. Pay attention when choosing the bolts (See
Fig.16)

Optional Overflow Oil Return Hose Installation
This installation guide shows how to connect a 90 degree fitting and plastic line/hose to the rear of
the cylinder. This line is then connected to the Power Unit (see below).
This is an option and is not necessary for your lift to function properly. Atlas cylinders and seal are
manufactured to exact tolerances. In the unlikely event that a leak were to develop in the cylinder
cup seal, the hydraulic fluid leaking past that seal would drip on the floor. This optional line (if
installed) would trap any fluid leaking past the cup seal and return leaked oil to the fluid reservoir.
Certain countries (not the USA) require these “overflow” lines to be installed. We believe that if the
cylinder were to develop a leak, it would be advantageous to “see the leak” and take steps to
replace a cylinder seal. The installation of this optional “overflow” line would prevent the user to
observe any cylinder leakage.
