P3 ALL AROUND - PRESTO PALLET POSITIONER
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 flat surface. Check the floor 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 floor. Support the base as you do this.
6. Check to see that the base frame of the unit is sitting firmly on the floor. 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 flatter, 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 inflated 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 fill
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.
