INTRODUCTION
This manual contains information to acquint you with the safe and proper installation, use and upkeep
of the machine. You should ensure that this manual is available to personnel working with the machine
and require its use by these personnel.
In the interset of safety, please read this entire manual carefully and be familiar with its contents
before you install, use or service the machine. If you have any questions about any instructions in
this manual, please contact your dealer or Southworth Products Corp.
Southworth’s product warranty is provided in the back of this manual. This instruction manual is not
intended to be or to create any other warranty, expressed or implied, including any implied warranty
of merchantability or tness for a particular purpose, all of which are hereby expressly excluded.
As set forth more specically in the product waranty, Southworth’s obligation unfder that warranty is
limited to the repair or replacement of defective components, which shall be the buyers sole remedy.
Southoworth shall not be liable for any loss, injury or damage to persons or proprrty, not for any defect,
indirect or consequential damage of any kind resulting from the lift table.
Things to Know
1.) Capacity on pneumatic lift/tilt tables is affected by plant air psi (pounds per square inch of
pressure).
2.) Plant air pressure is typically 80 to 90 psi.
3.) Speed on lift/tilt tables is affected by the cfm available (cubic feet per minute or air volume ow).
4.) The cfm is a function of the air compressor’s capacity and the pressure and the size of the lines
leading to the lift/tilt table.
5.) The cfm is best expressed as “free air.” Meaning it is measured (or calculated) as a volume
blowing out an open line.
6.) Southworth capacity ratings and speed estimates on all models are based on 80 psi at 80 cfm,
free air.
As a General Rule
1.) Increasing cfm will increase up speed.
2.) Increasing psi will increase capacity and up speed.
3.) Capacity and speed are a function of the air compressor and the associated airline network, not
the equipment.
4.) If a pneumatic lift/tilt is not fully raised or lowered and a load is removed from the unit, the unit will
raise slightly as the pressure on the air inside the airbag is reduced.
5.) If a pneumatic lift/tilt is not fully raised or lowered and a load is put on the unit, the unit will lower
slightly as the air is compressed inside the airbag.

SAFETY
The safety of all persons operating, maintaining, repairing or in the vicinity of the machine is of
paramount concern to Southworth. This is a powerful machine with moving parts and is capable
of causing personal injury if proper precautions are not taken. Therefore, throughout this manual,
Southworth has identied certain hazards that may occur in the use of this machine and provided
appropriate instruction or precautions that should be taken to avoid these hazards. In some cases,
Southworth has also pointed out the consequences that may occur if Southworth’s instructions or
precautions are not followed. Southworth uses the following system of identifying the severity of the
hazards associated with its products.
Southworth pneumatic lift/tilt tables are equipped with a pressure safety relief valve so overloading
will not “burst” the air bag.
Southworth pneumatic lift/tilt tables have a safety orice speed control. This regulates the down speed.
Should an air line rupture, the unit will descent at about the normal rate. This orice is not adjustable.
All Southworth pneumatic lift/tilt tables can be tted (optional) with industrial, high quality dampers to
provice smooth movement even when loads are abruptly introduced to the platform.
Southworth units are also equipped with safe, reliable Firestone air spring actuators rather than vinyl
air bags.
All Southworth models are designed with a generous safety factor of three to one.
Safety Considerations
Southworth pneumatic lift/tilt tables are designed and manufactured to meet the safety requirements
of the ANSI Standard MH29. Southworth pneumatic lift/tilt tables are equipped with a pressure safety
relief valve so overloading will not “burst” the air bag.

Southworth Air Bag Lift Tables 9
WARNING !
Only authorized personnel should perform inspection or maintenance and service procedures.
Unauthorized personnel attempting these procedures do so at the risk of severe
injury or death.
Failure to properly adhere to lift blocking procedures is to risk the sudden and uncontrolled de-
scent of the lift during maintenance or inspection. A falling lift can cause severe injury or death.
This procedure describes the only factory-approved
method of working under a lift. Follow these instruc-
tions EVERY time you plan to reach or crawl beneath
the lift to perform service or maintenance – no matter
how momentary that might be.
If the factory-provided maintenance device is dam-
aged or missing, stop immediately and consult the
factory for assistance. The manufacturer is not liable
for your failure to use the approved maintenance
device(s) and procedures that have been provided.
1. Any load must be removed from the lift prior
to engaging the maintenance device(s). These
devices are designed to support an unloaded
lift only. Failure to remove the load from the lift
prior to blocking could cause the failure of the
maintenance device(s) and allow the lift to fall
unexpectedly. This can result in personal injury or death, or permanent damage to the maintenance
device(s) and/or the lift.
2. Raise the lift to its fully raised position. If you do not, the maintenance device(s) may not be able
to be placed properly in its/their designed blocking position.
3. Remove the maintenance device(s) from its/their storage location and place it/them into the
engaged position as shown in Figure 1. (Note: further information may be useful here to provide
additional instructions as to the location and method of storage and engaged positions).
4. Lower the lift until it makes complete contact with the maintenance device(s). Re-check to ensure
that all provided devices are fully and securely engaged. If the device(s) is/are not fully engaged
the lift could fall unexpectedly, resulting in permanent damage to the device(s) or the lift.
DANGER !
If for any reason you are unable to lower the lift completely onto the maintenance device(s), stop
immediately and consult the factory. Failure to properly use the factory approved maintenance
device(s) could result in severe injury or death.
5. Once the maintenance device(s) is/are properly and securely engaged, continue to press the down
valve for an additional 5-10 seconds to relieve all pressure in the operating system.
warning
Failure to relieve operating system pressure could result in the sudden and unexpected release
of air during maintenance and/or repair of the lift and may result in severe injury or death.
6. Follow OSHA lock-out/tag-out procedures. Disconnect and tag all power sources to prevent an un-
planned or unexpected actuation of the lift.
7. Once inspection or work is complete, reverse the performance of the steps above to raise the lift off
the maintenance device(s) and place the device(s) back into its/their designated storage position(s).
Safe Servicing of the Lift

10 Southworth Air Bag Lift Tables
INSTALLATION INSTRUCTIONS
Preparations:
1. Before you start to install the lift, check for local codes and ordinances which may apply in your area. It
is your responsibility to obtain any necessary permits.
2. Read all of these installation instructions carefully. Be sure to read and understand all of the warnings!
3. Prepare air supply to have lter regular that provides psi.
Positioning the lift:
1. Remove the shipping material and unskid the lift.
2. Move the lift into position, supporting the base frame of the lift. Mount the lift on a rm level surface and,
if necessary, insert shims to level the lift. Install lag bolts to hold the lift in place. Make sure to shim or
grout under the base frame to prevent any exing.
NOTICE
Machine base lag anchors need to be sized for a minimum of 5000# pull-out force for each lag.
WARNING
If the lift is mounted on an unstable surface, it may tip over when in use. You may be hurt
and the lift and/or load may be damaged.
Air Line (if equipped): Connect airline between actuator device and supply lines.
WARNING!
Be sure the air line will not be pinched by the lift during operation. If you allow the line to be
pinched, the lift may not work properly. A hose may break, the lift may drop suddenly and
someone may be hurt.
Testing
1. Check all connections and make sure that they are tight and do not leak air.
2. Clear the area around the lift. Remove any loose wires, lumber or other material which might get in the
way of the lift as it is in use.
3. Operate the lift through its full range of travel. The lift should rise and lower smoothly and quietly. Raise
and lower the lift a few times to check the clearances around the lift table.
WARNING!
As the lift moves, “pinch points” are created. If you are standing too close to the lift when
it is moving, your arm or leg may be caught in the moving parts and you may be hurt. Stay
away from the pinch points when the lift is moving.
Complete Installation
1. Test the lift with the rated load. If the lift does not move contact Southworth for instructions.
WARNING!
Do not continue to use the lift if this happens. This can cause the lift to fail suddenly and you
may be hurt.

Before servicing the lift, read and understand this entire section and the section entitled “Operating
Instructions.”
Hazards
There are several hazards you should be aware of as you service the lift:
Before working on the lift be sure to insert and all maintenance devices.
WARNING!
As the lift moves, “pinch points” are created. Keep hands, feet and loose clothing
away from these pinch points. If your arms, hands or your clothing is caught, you
may be hurt.
CAUTION!
The warning labels on the lift are there for the safety of the operator. If the labels are
worn or missing, replace them
Routine Periodic Maintenance
Every month:
Visually inspect the leg rollers, center pivot bushings and the upper and lower hinge pins and
bushings.
Apply oil or WD-40 to all parts listed above.
Note: Although the bearings are “lifetime lubricated,” their performance may be extended by
additional periodic lubrication (WD-40).
Every six months:
Check all of the pneumatic ttings and hoses and repair the connections if necessary. Occasionally,
the ttings can be worked loose by vibrations from the lift.
Check all lag anchors to make sure they are tight.
WARNING!
If a pneumatic tting becomes loose or if a pneumatic hose breaks, the air will escape
from the system under pressure. If the lift is elevated when this happens, it will drop
very quickly. Someone may be hurt or the product or the lift may be damaged.
