1SAFETY AND OPERATING INSTRUCTIONS
1. When using this lift, basic safety precautions should always be followed,
including the following.
2. Read all instructions in this manual and on the lift.
3. Inspect lift daily. Do not operate if it malfunctions or problems have been
encountered.
4. Never attempt to overload the lift. The manufacturer’s rated capacity is shown on
the identification label on the power side column. Do not override the operating
controls or the warranty will be void.
5. Before driving vehicle between the towers, position the arms to the drive-through
position to ensure unobstructed clearance. Do not hit or run over arms as this
could damage the lift and/or vehicle.
6. Only trained and authorized personnel should operate the lift. Do not allow
customers or bystanders to operate the lift or be in the lift area.
7. Position the lift support pads to contact the vehicle manufacturers recommended
lifting points. Raise the lift until the pads contact the vehicle. Check pads for
secure contact with the vehicle. Check all arm restraints and insure they are
properly engaged. Raise the lift to the desired working height.
8. Some pickup trucks may require an optional truck adapter to clear running boards
or other accessories.
NOTE: Always use all 4 arms to raise and support vehicle.
9. Caution! Never work under the lift unless the mechanical safety locks are
engaged.
10. Note that the removal or installation of some vehicle parts may cause a critical
load shift in the center of gravity and may cause the vehicle to become unstable.
Refer to the vehicle manufacturer’s service manual for recommended procedures.
11. Always keep the lift area free of obstruction and debris. Grease and oil spills
should always be cleaned up immediately.
12. Never raise vehicle with passengers inside.
13. Before lowering check area for any obstructions.
14. Before removing the vehicle from the lift area, position the arms to the drive-
through position to prevent damage to the lift and /or vehicle.

4INSTALLATION REQUIREMENTS
IMPORTANT: It is the user’s responsibility to provide a satisfactory installation
area for the lift. Lifts must only be installed on level concrete floors with a
minimum thickness of five (5) inches or 130mm. Concrete must have a minimum
strength of 4000 psi or 30 MPa and should be aged thirty (30) days prior to
installation. Please consult the architect, contractor or engineer if doubt exists as to
the strength and feasibility of the floor to enable proper lift installation and
operation.

5
It is the user’s responsibility to provide all wiring for electrical hook-up prior to
installation and to insure that the electrical installation conforms to local building
codes. Where required, it is the user’s responsibility to provide an electrical
isolation switch located in close proximity to the lift that will enable emergency stop
capability and isolate electrical power from the lift for any servicing requirements.
Tools Required:
1. 16ft. Measuring Tape
2. Chalk Line
3. Rotary Hammer Drill
4. diameter Masonry Drill Bit
5. Hammer
6. SAE Wrenches and Ratchet Set
7. 2ft. Level
8. 4ft. Level
9. Crow Bar
10. One 12ft. Step Ladder
11. Side Cutters
12. Screwdrivers
13. 15ft. Bleeder Hose (Clear) w/ 3/8”JIC Swivel F fitting on one end
14. 4"x4" Wooden Blocks (for unpackaging)
5INSTALLATION INSTRUCTIONS
When the lift arrives on site, please read the owner’s manual and check for any freight
damages. Also, check the contents to make sure no parts are missing before starting
installation. Gather all the tools listed and make sure the installation instructions are
fully understood before commencing installation.
5.1 UNPACKING PROCEDURE
1. Important! Place the main structural components on wooden blocks so that the steel
frames can be removed.
2. Remove plastic wrapping.
3. Remove crossmember, and hydraulic line.
4. Remove steel frames.
5. Lay towers on floor with the carriage side up.
6. Check the installation area for obstructions. (Lights, Heating Ducts, Ceiling, Floor
Drains...etc.)

7. Prepare the bay by selecting the location of the lift relative to the walls. Clear area of
all packaging materials to avoid trip hazards. Draw a chalk line on the floor to
represent the center line of the bay and a second chalk line crossing at 90°for
locating the lift towers. Refer to Figure 3.
5.2 BAY LAYOUT
FIGURE 3 – BAY LAYOUT
5.3 SAFETY SHUT-OFF BAR INSTALLATION
Note: The safety shut off will disconnect the power to the power pack when an
obstruction touches the padded bar or the carriages reach their maximum
extension. The safety shut off switch is factory pre-wired. Refer to Figure 4.
Note: This procedure can be done on the floor.
1. Attach the actuator mounting bracket (1-1378) to the crossmember using hex head
bolt 1/4” NC x 3/4” lg. bolt (6-0178), lockwasher 1/4” dia. (6-0056), and hex nut 1/4”
NC (6-0032).
2. Attach the actuator bar assembly to the actuator mounting bracket assembly using hex
head bolt 1/4” NC x 1 1/4” lg. (6-0027), lockwasher (6-0056), and hex nut 1/4” NC
(6-0032).

3. Slide the safety shut-off microswitch assembly over open end of actuator bar and bolt
the assembly to the crossmember using hex head bolt 1/4” NC x 3/4” lg. (6-0178),
lockwasher (6-0056), and hex nut 1/4” NC (6-0032).
4. Bolt actuator extension (1-1379 12ft Model, 1-1823 14ft Model) onto open end of

0056), and hex nut 1/4” NC (6-0032).
Figure 4 – Safety Shut-Off Bar Installation
5.4 SAFETY SHUT-OFF BAR ADJUSTMENT
Note: This procedure must be done last. Refer to Figure 4.
1. When the lift is fully installed, leveled. and operational, extend the carriages to their
full upper limit.
2. Lower the carriages about 1/4” to 1/2”.
3. Bolt actuator extension (1-1379 12ft Model, 1-1823 14ft Model) onto open end of
actuator bar using (2x) hex head bolt 1/4” -NC x 1 1/4” lg. (6-0027), lockwasher (6-
0056), and hex nut 1/4” NC (6-0032).

4. Adjust the ¼” NC x 2” lg. Hex bolt so that the end of the bolt is in contact with the
carriage. Tighten the ¼” NC hex nut on the bolt.
5.5 TOWER POSITIONING AND SETUP
1. Locate the power side and slave side tower to the relative position as shown in
Figure 3. Double check all dimensions.
2. Using a step ladder, install the crossmember. Raise and place the crossmember
mounting hooks over the top of the tower. Install and tighten the crossmember using
eight (8) 1/2”-13UNC x 1¼”LG. hex head bolts, flat washers, lockwashers and hex
nuts.
3. Check the towers to make sure they are located, and positioned in the correct
location.
5.6 ARM INSTALLATION
1. Remove the four (4) 5/16”-18UNC x 3/4”LG. hex head bolts that are holding the
arm pins to the arm. Install the arms on the carriages.
2. Grease and insert arm pins. Align the notch on each arm pin with the tapped hole
on the arm, and using the 5/16”-18UNC x 3/4”LG. hex head bolt removed in
previous step, reinstall and tighten securely.
3. Using two (2) 5/16”-18UNC x 1 ¼” LG. hex head bolts and two (2) 5/16”
