Upon receiving this machine, remove all packing material and check the machine and
components for damage or missing parts. Contact the manufacturer if damage or missing parts
are found.
The machine must only be used on at, level surfaces. Uneven surfaces

4.2 Machine Setup
Do not inate the system to more than 30 PSI/2.1 Bar while unloaded
and at the fully raised position. If system pressure exceeds 65 PSI/4.5
Bar failure can occur and cause damage to the machine and/or injury to
the operator.
1. Clear area of all packing material and other debris.
2. Carefully insert the forks of fork truck or stacker into the fork pockets of the machine. Raise
the machine off of the shipping skid and remove the skid. Lower the machine onto the oor.
3. With no load on the machine, pressurize the system to 30 PSI/2.1 Bar via the valve stem
on the pressure tank. Do not exceed 30 PSI /2.1 Bar.
4. Use a fork truck to gently place the heaviest expected load onto the platform. Load must
not exceed 4,500 lb.
5. Slowly open the manual air discharge valve to release pressure from the system. Once the
load is fully lowered, close the manual air discharge valve.
As the load is removed from the pallet, the lift will raise to maintain proper working height. Actual
working height can be adjusted by increasing or decreasing the system pressure. Do not exceed
30 PSI /2.1 Bar when unloaded and in the fully raised position.

5. Operation
Before each use check the machine for damage or excess wear. If damage or excessive
wear is found do not use the machine, contact the manufacturer for repair information and/
or replacement parts.
Do not sit, stand, or ride on the machine.
Do not enter under the platform unless it is mechanically locked.
Keep hands, feet, and loose clothing away from moving parts.
Load and unload the machine gradually to avoid bouncing of the
machine.
Loads should be added and removed from the platform uniformly.
Uneven loading can cause excessive wear and instability. Uneven loads
can cause unintentional rotation of the turntable, which can cause the
load to fall and lead to severe injury.
Do not use with damaged pallets or pallets with exposed fasteners.
Damaged pallet pieces and/or fasteners must not extend more the 1/8”
below the rotator ring.
This machine is to be operated and transported on at, level surfaces
only.
5.1 Manual Loading & Unloading
While loading and unloading manually, always keep the load as uniform across the platform as
possible to avoid instability and excess wear. Always turn the platform slowly to avoid dislodging
the load on the platform.
As the load is added and removed from the pallet, the height of the platform will raise or lower
to maintain the proper working height. To adjust the working height, add or remove air from the
system.

Presto Lifts P3 All-Around Air Manual
12
5.2 Fork Truck or Stacker Loading & unloading
When loading and unloading with a fork truck or stacker, the load should be distributed evenly on
the pallet.
When placing a pallet onto the machine, slowly lower the pallet onto the platform until the load is
completely supported by the machine. Slowly remove the forks from the pallet.
Do not drop the pallet onto the platform or damage may occur.
When removing the load from the machine, slowly insert the forks into the pallet and slowly lift the
pallet off the platform to avoid sudden changes in height which can damage the machine or cause
injury.
5.3 Transporting
Failure to secure the load and turntable while transporting can lead
severe injury.
Do not drop the machine onto the oor or damage may occur.
If equipped with a portability kit, always ensure the oor lock is engaged
before using the machine.
The machine can be transported with or without a load on the platform. If transporting the machine
with a load on the platform, always secure the load to the platform and secure the turntable from
rotating unintentionally.
The machine can be transported by an appropriately rated fork truck or stacker, or by the optional
portability kits.
5.3.1 Transporting with Fork Trucks and Stackers
Insert the forks into the fork pockets and raise the machine off the oor. Move the machine to the
desired location and lower the machine onto the oor. Remove the forks from the fork pockets.
5.3.2 Transporting with Portability Kits
5.3.2.1 Caster Package
If equipped with the caster package, always
engage the oor lock before loading and
unloading. Disengage the oor lock to move
the machine to the desired location.

Presto Lifts P3 All-Around Air Manual

5.3.2.2 Leveling Feet
If equipped with the leveling feet package, the
machine can be raised approximately three
inches to accommodate the use of manual/
powered pallet jacks.

6. Maintenance & Repair
Only trained and/or qualied personnel shall perform maintenance on
this machine.
Never perform maintenance on the machine while a load is on the
platform.
Do not enter under the platform unless it is mechanically locked.
High pressure air can cause severe injury. Always relieve the pressure
in the system before performing maintenance.
6.1 Maintenance Pins
1. With the machine in the raised
position and the load removed,
remove the maintenance pin
from the stowed position on the
leg, near the roller.
2. Insert the pins into the hole in
the top of the roller track (both
sides).
If not supplied with maintenance
pins, two 3/8” diameter by 3” long
bolts may be used instead.
