OWNER’S MANUAL
INTRODUCTION
The Pallet leveler PL 2002 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 PL 2002. 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 PL 2002 unit. Please be sure that this manual
is available to anyone who uses or services the unit.

INSTALLATION INSTRUCTIONS
Unpacking the Unit
1. Before you start to install the unit, 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 PL 2002 be
located on a smooth and at surface. Check the
oor surface carefully and make sure that it is free
of all loose debris and dirt.
surface area.
7. If you have any questions about the steps in
the installation process, please call EdmoLift.
Set-Up and Instructions
WARNING!
The unit is attached to the skid using
metal bands. These bands are under
high tension. The edges are sharp.
Wear safety glasses and gloves when
you handle or cut the banding.
5. Remove the metal 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 13 mm out of level in relation
to any other part, reposition to a atter, more level
The PL 2002 can be setup to handle pallet loads
of any weight within the unit's capacity range.
Load capacity depends on the initial actuator
pressure. The actuator pressure can be set from
0.41 bar to 4,21 bar to achieve capacities ranging
from approximately 180 kg to 2000 kg. Once
air is inated into unit's air actuation system, a
corresponding load capacity can be set. The unit
will then lower or rise as the load is being added
or removed from the unit, and thus works as an
automatic pallet leveler. A rule of thumb for setting
up the unit is that the amount of air inated into the
air actuator should allow the unit to be lowered to
its compressed height with load equal to 75% of
the set capacity (including the weight of the pallet).

Routine Periodic Maintenance
Every 90 days -
• Check for loose hardware and signs of

Setup Procedures
1. The PL 2002 must be properly installed
according to the installation section of this manual.
2. With no load on the unit use shop air or an
air compressor to pressurize the air actuation
system to the required initial pressure. The unit
is equipped with an air pressure gauge and an
air manifold valve that includes a valve stem, a
manual relief knob, and a safety relief valve. Add
air to the actuator system through the valve stem,
and release air from the system by loosening the
manual relief valve.
3. Gradually load the PL 2002 to 75% of the setup
capacity, up to 1500 kg maximum. Check to see if
the unit is fully compressed. If not, turn the manual
relief knob to slowly bleed air out of the system until
the platform reaches minimum, fully compressed
height; then tighten the manual relief knob. The
setup procedure is now complete and the PL 2002
is ready for use.
4. If a different load is to be handled, or if the
operator prefers a higher or lower loading/
unloading position from that of the standard setup,
add air to, or bleed air from the actuation system to
achieve the necessary height. The gauge should
never be more than 4,27 bar when the unit has
no load on it.
* NOTE: The actuation system of the PL 2002
contains captive air much like an automotive
tire and will 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
If you do not know or cannot estimate the weight
of the pallet load to be handled, use the following
instructions:
With no load on the unit, pressurize the actuation
system to 4,27 bar. Place about half of the pallet
load onto the unit, then slowly bleed air from the
system using the manual relieve knob until the
pallet reaches the most convenient height for the
operator to continue loading the pallet.
