4P3 ALL AROUND - PRESTO PALLET POSITIONER
INTRODUCTION
The P3 All Around Pallet Positioner is a simple device that will automatically maintain 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 P3
(P3 All Around Pallet Positioner). 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 Figures 5 and 6.
This manual contains information to help you to learn about the safe and proper installation, use,
and upkeep of your P3. Please be sure that this manual is available to anyone who uses or services
the unit.
P3 units may be used in a wide variety of industrial settings. The instructions in this manual are not
necessarily all-inclusive, as Presto cannot anticipate all conceivable or unique situations.
In the interest of safety, please read this whole manual carefully. Be
familiar with the contents of this manual before you install or use the
P3 unit. If you are not sure of the proper procedure to be followed,
please call Presto Lifts for more information.
Presto’s product warranty is shown on the rear cover of this manual. This instruction manual is not
intended to be or to create any other warranty, express or implied, including any implied warranty of
merchantability or tness for a particular purpose, all of which are hereby expressly excluded. As

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.
Please be sure that all of the labels are in place, and are visible to the
machine operators. Never paint over the labels. If any of the labels

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 warn-
ings.
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 P3 All Around 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 Presto Customer
Service at 1-800-343-9322.
Overview
The P3 All Around 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 P3 All Around 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 P3 All Around 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.

Safe Servicing of the Lift
The two holes in the base roller tracks, one on
each side (see Choked Position image) are
intended for 3/8 inch diameter pins to be utilized
to chock up the lift whenever maintenance or
under lift troubleshooting is performed. When
chocks not in use place in the Stowed Position,
see image on the right.
Note: Earlier designs may not have had these
pins or the stowed position holes. If your unit
was not supplied with these, use two 3/8 x 3''
long bolts.
