IMPORTANT INFORMATION
1. Always inspect the lift for damage and make note of any damage on the bill of lading.
2. In case of freight damage, call the truck line immediately and report the damage as a freight claim.
3. IMPORTANT! Make sure you have extra help or heavy duty lifting equipment when unloading and
assembling the lift.
4. Please read the safety procedures and operating instructions in this manual before operating lift. Keep
this manual near lift at all times. Make sure all operators read this manual.
5. IMPORTANT! Are you installing in a level location? (Lift must be anchored in place if slope is greater
than 1/8” per foot.)
6. Make sure you have enough room to install the lock rods. You will need at least 6’ of clearance from the
opposite end of the power unit end of the lift and 6’ at the power unit end. The power unit may be
installed on the driver front or the passenger rear corner.
7. Never raise a car until you have double checked all bolts, nuts and hose fittings.

SELECTING SITE
Before installing your new lift, check the following.
OVERHEAD OBSTRUCTIONS: The area where the lift will be located should be free of overhead
obstructions such as heaters, building supports, electrical lines etc.
FLOOR REQUIREMENTS: Visually inspect the site where the lift is to be installed and check for cracked or
defective concrete. This lift must be installed on a solid level concrete floor with no more than 2 degrees of
slope. A level floor is suggested for proper installation and level lifting. If a floor is of questionable slope,
consider a survey of the site and/or the possibility of pouring a new level concrete slab. This lift is designed to
be installed on a minimum of 4-1/4”" thick, 3000psi, with steel reinforced concrete. Do not install this lift on
asphalt, wood, or any other surface other than described. This lift is only as strong as the foundation on which
it is installed.
NOTE: This Lift does not require bolting to the floor (BUT) If you choose the option to anchor the Lift to
the floor, please follow the detailed instructions in the manual and criteria above. (See page 16)
DO NOT install this lift outdoors unless special consideration has been made to protect the power unit from
weather conditions. The Power unit is not water proof!
DO NOT install lift close to wall. It is necessary to leave adequate clearance for safe movement around lift.
Suggested clearance to be 1 meter (3 feet) minimum.
OPERATING CONDITIONS: Lift is not intended for outdoor use and has an operating ambient temperature
range of 41º-104ºF (5º-40ºC).

INSTALLATION INSTRUCTIONS
Improper installation can cause accelerated wear, resulting in catastrophic failure which may cause
property damage and / or bodily injury. Manufacturer will assume no liability for loss or damage of any
kind, expressed or implied, resulting from improper installation or use of this product. Read this
installation manual in its entirety before attempting to install or operate the lift.
1. Remove plastic wrap from top Runway and remove all hardware. This includes the Power Unit,
‘wire braided’ Hydraulic Hose, Jack Tray, Lock Ladders and Hardware Box.
2. While the Mainside Runway (Fig. 2) is upside down, find the end of the Hydraulic Hose that is
already connected to the Cylinder. Locate hole on the side of the Mainside Runway and install
the 90 degree fitting securing to runway with Jam Nut. Also remove the plastic shipping ties
securing the pre-installed Cables.
3. With the Mainside Runway upside down, pull to extend the Cable Ends through the holes on
each end of the Runway. Also, ensure the hydraulic fittings are tightened.

5. Now unbolt the top Mainside Runway (#51) taking the necessary safety precautions to support
runway, as it will need to be flipped over. Note: Using some type of hoist is recommended to
carefully flip the Runway over, so it’s no longer upside down.

6. Locate the Mainside Runway in your bay with the Hydraulic Fitting (#86) facing toward your
previously chosen corner for the Power Unit.
7. Unbolt all four Columns from the shipping brackets and place the Power Unit Column (#1) with
mount bracket in the above chosen corner. Arrange the other three Sub Columns (#2) in the
remaining corners.
8. Unpack the Crossbeams, Ramps, Drip Trays, and Caster Kit from the lower Sub Runway.
Remove the Safety Latch covers (#14) from Crossbeams. They will be reinstalled later.
9. Arrange the Crossbeams so that the Latches’ Linkage Rods are facing outward and the Short
Rod (#70) is closest to the Power Unit Column, as shown below in Fig.3. 

10. If you have means for securely lifting the
Crossbeam, lower it into the tops of the
Columns. If not, the Columns will have to be
placed horizontally, in order to install the
Crossbeams into the Columns. Then, the
entire end structure (two columns and
crossbeam) will need to be stood up as one.
11. Unpack the Lock Ladders (Fig. 4) from the
package and slide them into the precut slot on
the Rub Blocks (#56) inside each column. After
removing the top Nut from the Lock Ladder,
you are ready to install the Top Caps A & B
(#3 & #4) on the columns.
12. Be aware of the offset hole in column’s Top
Caps. Arrange Top Caps so that the cable
mounting holes are closest to the runways.
Use provided Bolts, Nuts, Washers and Lock
Washers to install Top Caps, as shown in Fig.
4 & 4b.
Fig. 4b
13. Secure Top Cap and Lock Ladder assemblies
together with Washer and Nut as shown in Fig
4b. Note: Ensure Jam Nut is positioned
below Top Caps. Position the Crossbeams at
the second lowest locking position on all columns

14. Stand up and arrange the two end structures (Columns & Crossbeams) so that the outside of
the Crossbeam rail to the outside of the other Crossbeam rail ‘diagonal’ measurements are
close. Compare the measurements from the left and the right until they are diagonally within
1/2”. Note: The ½” variance will help in mounting the Runways later.
15. Carefully lift and position each Runway into place and secure to Crossbeams ends with the
provided Hex Bolts (#44), Mounting Plate (#42) and hardware (#19, 45, 46 & 47) as shown in
Fig. 5 & 5b. The lift will square itself as you further assemble it.
Note: Ensure to install the ‘offside’ Sub Runway opposite from the Main side Runway and
Power unit Column, as shown in Fig.5b.
