INTRODUCTION
The PalletPal 360 Air Level Loader is a simple device that will automatically main-
tain a load at the ideal height for manual loading and unloading. If a palletized load
is placed on the unit, the unit gradually rises as boxes or parts are removed. This
automatically maintains the top of the load at the correct working height.
The unit may also be used for the reverse application. An empty pallet may be placed
on the PalletPal 360 Air. The unit gradually lowers as boxes or parts are added.
Again, this keeps the top of the load at the correct height. Complete pallets may be
loaded or unloaded using a stacker or fork lift. See page 13.
This manual contains information to help you to learn about the safe and proper
installation, use, and upkeep of your PalletPal 360 Air unit. Please be sure that this
manual is available to anyone who uses or services the unit.
PalletPal 360 Air units may be used in a wide variety of industrial settings. The

WARNING!
Do not inate the system to more than 30 PSI at the fully
raised position with no load. If the actuation system pres-
sure is higher than 65 PSI under any circumstance it may
cause the failure of the air actuation system thus resulting
in severe injury.
WARNING!
Never try to service or troubleshoot the machine without
carefully reading the maintenance section of this manual
and reviewing "Safe Servicing of the Lift", gure 8 on page
14. Otherwise severe personal injury may result.
Figure 1 (beginning on page 10) shows all the labeling on this unit.

INSTALLATION INSTRUCTIONS
Unpacking the Unit
1. Before you put the unit in service, check for local codes and ordinances that may apply. It is your
responsibility to obtain any necessary permits.
2. Please read all of these instructions carefully. Be sure to read and understand all of the warnings.
3. Inspect the shipping pallet carefully for any damage which may have affected the unit. If you see
signs of damage, notify the shipper immediately. Also make a note of this on the shipping papers that
you are asked to sign.
4. Choose the place where you want to set the unit. It is very important that the PalletPal 360 Air be
located on a level, smooth and at surface. Check the oor surface carefully and make sure that it is
free of all loose debris and dirt.
5. Remove the banding that secures the unit to the pallet. Remove all packing material. Shift the unit
to the oor. Support the base as you do this.
6. Check to see that the base frame of the unit is sitting rmly on the oor. Try to move or rock the
frame of the unit. The base frame should be stable, and should not move. Check to see that the base
frame is level. If any part of the base frame is more than 1/2" out of level in relation to any other part,
reposition to a atter, more level surface area.
7. If you have any questions about the steps in the installation process, please call Southworth Cus-
tomer Service at 1-800-743-1000.
Overview
The PalletPal 360 Air can be setup to position pallet loads ranging from approximately 300 lbs to 4500
lbs (140kg to 2025kg). Once air is inated into unit's air actuation system load capacity can be set. The
gauge must never be more than 30 PSI (2.1 BAR) when the unit has no load on it and is in the fully
raised position. The unit will then lower or rise as the load is being added or removed from the unit,
(see quick setup section below), and thus works as an automatic level loader holding the top layer of
goods at a convenient height.
*NOTE: The actuation system of the PalletPal 360 Air contains captive air much like an automotive
tire and may lose small amounts of air over time. Therefore, air may have to be occasionally added to
the system to compensate for the loss.
Quick Setup
Read and understand entire manual before performing quick setup.
With no load on the unit, pressurize the actuation system with 30 PSI (2.1 BAR) of air via the air ll
valve stem, see Figure A on next page. Using a fork lift or stacker place the heaviest, complete pallet
load on the unit, (maximum weight 4,500 lbs). Slowly open the Manual Air Discharge Valve allowing
air to escape. When the unit is fully lowered, close the Air Discharge Valve. The PalletPal 360 Air is
now set for that pallet load.
As the upper layers on the pallet are removed in even layers the unit will rise. When the pallet is near
empty the unit will be at the top of its travel.
Setting the ideal load height is subjective. Some operators prefer to have the load held slightly higher.
If so increase the air pressure slightly. If the load is being held too high slightly discharge some air. Air
pressure must never exceed 30 PSI when the lift is unloaded or 65 PSI when the lift is loaded.

OPERATION NOTES
WARNING!
Never sit or ride on the turntable or operate the unit if anyone is on it.
WARNING!
Never operate the unit if the load is off center. The load may shift, and you may be injured.
This can also damage the unit.
WARNING!
Keep the area around the unit clean. Do not allow any dirt, debris, spilled oil, or excess
grease to collect. These materials may cause you to slip while the unit is operating, and
you may be injured.
WARNING!
Stay clear of the turntable when it is moving. As the pallet turns, a part of the load may rotate
around and hit you. Never turn the load when anyone is standing beside the unit.
WARNING!
Do not try to use this unit with damaged or broken pallets. Broken pallets may have boards
or nails which hang down below the main part of the pallet. As the pallet is turned, these
boards or nails may catch on the frame of the unit. This can cause the pallet to stop turning
suddenly, causing the load to shift.
You may be injured, and the unit may be damaged. The boards or nails on the bottom of the
pallet should not extend down more than 1/8 inch.

Figure 4. Warning - Load and Unload in
Even Layers
WARNING!
Ensure that loading and unloading of the PalletPal 360 Air is done in even layers.
Loading or unloading a load on one side may cause the load to tip over and you
may be injured. This can also damage the unit. See Figure 4.
2. Never use the unit when anyone is sitting or riding on the turntable.
3. Do not try to use this unit with damaged or broken pallets. Broken pallets may have boards or nails which hang
down below the main part of the pallet. As the pallet is turned, these boards or nails may catch on the frame.
The pallet may stop turning suddenly and this can cause the load to shift. You may be injured and the unit may
be damaged. If the boards or nails on the bottom of the pallet extend down more than 1/8 inch, they will interfere
with the turning action.
4. Stay clear of the turntable when it is moving. As the pallet turns, a part of the load may rotate around and hit you.
5. Keep the area around the unit clean. Do not allow any dirt, debris, spilled oil, or excess grease to collect. These
materials may cause you to slip while the unit is operating and you may be injured.
