SAFETY
The safety of all persons operating, maintaining, repairing or in the vicinity of the machine is of
paramount concern to Southworth. This is a powerful machine with moving parts and is capable of
causing personal injury if proper precautions are not taken. Therefore, throughout this manual, Southworth
has identied certain hazards that may occur in the use of this machine and provided appropriate
instruction or precautions that should be taken to avoid these hazards. In some cases, Southworth has
also pointed out the consequences that may occur if Southworth’s instructions or precautions are not
followed. Southworth uses the following system of identifying the severity of the hazards associated
with its products:
Safety Considerations
Southworth Pallet Rotators are designed and manufactured to meet applicable portions of the safety
requirements of the ANSI Standard MH29.2, Industrial Tilters.
NOTICE
This power unit contains a hydraulic pump that is capable of developing excessive
pressure. A pressure relief valve is used to set the pressure at a desired level. Tampering
with, adjusting, modifying, or removing the relief valve is extremely dangerous and not
recommended. only a trained hydraulics technician, using a calibrated hydraulic pressure
gauge to assure the proper pressure setting is achieved, should make adjustments to
the relief valve.
All Southworth Pallet Rotators are tted with industrial, high quality over-center valves to provide for
smooth movement even when loads are abruptly introduced to the platform.
All Southworth models are designed with a generous factor of three to one for all critical loading
supporting elements.

INSTALLATION &
INSTRUCTIONS
Preparation
1. Before you start to install the machine, check for local codes and
ordinances, which may apply in your area. It is your responsibility
to obtain any necessary permits.
2. Read all of these installation instructions carefully. Be sure to
read and understand all of the warnings!
WARNING!
Protect the hydraulic power unit from rain or moisture.
If the electrical parts in the power unit get wet, workers
may be hurt by electrical shock or the electrical parts
may fail.
WARNING!
The electric motor in the Pallet Rotator can create sparks.
Do not install the hydraulic power unit in an area where
ammable gases may be present.
Positioning the lift
1. Remove the shipping material and unskid the machine.
2. Move the machine into position, supporting the base frame.
Mount the machine on a rm level surface, if necessary, insert
shims to level.
3. Adjust the clamping pressure to the desired load pressure using
the adjustable pressure knob on the side of the unit.
WARNING!
If the Pallet Rotator is mounted on an unstable surface,
it may tip over when in use. You may be hurt, and the
machine or the load may be damaged.
NOTICE
It is very important to keep the hydraulic oil free from
dirt, dust, metal chips, water and other contamination.
Most of the problems with hydraulic systems are caused
by contamination of the oil.
Electrical Connections
DANGER!
The Pallet Rotator may use a power supply of up to 460
Volt AC. This voltage can kill you. Do not work with the
electrical parts unless you are a qualied electrician.
1. A machine with a 115 Volt power unit needs to have a designated
outlet and breaker of at least 30 AMP service. Consult Customer
Service for performance concerns.
2. A machine designed for three phase AC, you must be sure the
pump and motor is turning in the right direction. The machine should
start to move quickly when you press the up or down button. If the
machine does not move in 2 or 3 seconds, do not try to operate the
machine! Exchange any two of the three phase leads. If this does
not correct the problem, please contact Southworth ‘s Customer
Service Department.
Testing
1. Check the level of the hydraulic oil. With the machine in the home
position the tank should be full, add oil if necessary.
2. Clear the area around the machine. Remove any loose wires,
lumber or other material that might get in the way of the machine
as it is in use.
3. Operate the rotator through its full range of motion and operate
the clamp and unclamp function. The rotator and clamp functions
should operate smoothly and quietly. Raise and lower the lift a few
times to check the clearances around the lift table.
WARNING!
As the machine moves, “pinch points” are created. If
you are standing too close to the machine when it is
moving, your arm or leg may be caught in the moving
parts and you may be hurt. Stay away from the pinch
points when the lift is moving.
Completing Installation
1. Test the machine with the rated load. If the machine does not
move and you hear a loud squealing noise, this means the pres-
sure relief valve is operating. Contact Southworth for instructions.
NOTICE
Do not continue to use the machine if this happens. The
pump will overheat very quickly and may be permanently
damaged.
NOTICE
Excessive clamping forces may damage the load. Re-
lease the clamp from the load before making any adjust-
ments.
OPERATING INSTRUCTIONS
• Load dimensions and weight must be within the pa-
rameters of the Pallet Inverter – 4,400 lbs max, and
anywhere between 30” and 60” in height.
• Load must be placed into and removed from the In-
verter using a fork lift.
• Press and hold the Unclamp button until the opening
is large enough to accept the pallet load.
• Press and hold the Clamp button until the load is secure
within the platens of the Inverter.
• Press and hold the Clockwise or Counterclockwise
button until the pallet load is in the desired orientation.
• Press the Unclamp button until the pallet load is free
of the platens and can be removed with the fork lift.
When adjusting the clamping pressure on the SR-44 ensure the
load is in a safe position so none of the product will transition to
the operator. Adjust the pressure knob counter clockwise for lower
clamping forces and clockwise for higher clamping forces. Test the
load to ensure proper settings.

Hazards
There are several hazards you should be aware of as you service
the lift. Before working on the machine be sure to insert any and
all maintenance devices. See gure 1.
DANGER!
The machine may use a power supply of up to 575 Volts.
This voltage can kill you. Do not work with the electrical
parts unless you are a qualied electrician.
CATUION!
Do not change the setting on the relief valve in the pump.
If you do, this may damage the machine and you may be
hurt. The relief valve has been included for the protection
of all of the workers who use the machine.
CAUTION!
Before working on the machine, be sure to release pres-
sure on the hydraulic system.
CAUTION!
The warning labels on the machine are there for the
safety of the operator. If the labels are worn or missing,
replace them.
Routine periodic maintenance
Every month:
1. Visually inspect the center pivot bearing, cylinder clevis pins and
bushings. Apply oil or WD-40 to all parts listed above.
2. inspect hoses and ttings for leaks.
Note: Although the bearings are “lifetime lubricated” their perfor-
mance may be extended by additional periodic lubrication (WD-40).
3. Check the level and appearance of the hydraulic uid. Use a
dipstick to check the oil level and add oil if necessary. Change the
oil if it has darkened from its original color, turned milky white or if
it feels gritty or sticky.
4. Inspect the overall condition of the lift; looking for loose or worn
out components.
NOTICE
It is important to use hydraulic uid with the correct grade
and properties. The hydraulic uid the machine is provided
with is Conoco AW-32.
Every six months:
1. Visually inspect the center pivot bearing, cylinder clevis pins and
bushings. Apply light oil or WD-40 to all parts listed above.
WARNING!
If a hydraulic tting becomes loose or if a hydraulic
hose breaks, the hydraulic uid will escape from the
system under pressure. Someone may be hurt or the
product or the machine may be damaged.
2. Drain all of the hydraulic uid from the tank and cylinders and
discard it.
3. Remove the spin on lter from the tank. Discard and install new
lter.
4. Rell the tank with new hydraulic uid. The hydraulic uid should
be approximately 3/4” from the top of the tank.
5. Inspect the overall condition of the rotator; looking for loose or
worn out components.
6. Add grease to all grease ttings.
TROUBLESHOOTING
All service should be done by qualied personnel. Qualied per-
sonnel should be able to read and understand wiring and hydraulic
diagrams. They should be able to troubleshoot live electrical circuits
safely and in accordance with accepted practice. FOR SAFETY’S
SAKE, if in doubt, please contact your dealer or Southworth Prod-
ucts Corporation Customer Service Department at [phone]
or [phone].
Before servicing the Pallet Rotator, read and understand this entire
section and the safety information. Before working on the machine,
be sure to insert any and all maintenance devises. Failure to do so
may result in damage to the machine and severe personal injury!
If the machine will not clamp or rotate:
NOTICE
Do not continue to hold the “CLAMP” or “ROTATE”
button for more than 2 or 3 seconds. You may damage
the pump.
1. The machine may be overloaded. Check the actual weight of the
load. The rated capacity of the machine is shown on the table sides.
CAUTION!
Do not change the setting on the relief valve in the
pump. If you do, this may damage the machine and
you may be hurt. The relief valve has been included
for the protection of all of the workers who use the
machine.
2. If the motor is not running, check the main disconnect switch, the
fuse(s) and the wiring to the motor.

10 Southworth PalletPal Pallet Inverter/Rotator
Using an external lifting mechanism, such as a crane or a forklift.
Raise the machine and insert any and all maintenance devises.
3. Check the level of the hydraulic uid. Use a dipstick to check
the oil level, add oil if necessary.
4. If the machine rotates but does not rotate completely, the ma-
chine may have an up limit switch. This switch may just need to
be re-adjusted.
CAUTION!
Do not disconnect the up limit switch. Instead, loosen
the adjusting screw and change the position of the arm.
If you do disconnect the switch, when the lift platform
moves up, it may not stop at the correct spot, the ma-
chine may be damaged and people may be hurt.
5. On a machine equipped with a three-phase motor, the motor may
be running backwards. If the motor has been wired correctly, the
machine should start to move in 2 or 3 seconds after you hit the
“CLAMP” or “ROTATE” button. If the machine does not move, try
reversing any two power leads.
6. On a machine equipped with a three-phase motor, the motor may
be “single phasing.” When this happens, the motor hums but does
not turn. If this is the case, one lead of the three-phase line has
been interrupted. Check the motor wiring and line fuses.
7. The power supply to the motor could be too low. Check the volt-
age at the motor when it is under a full load. The supply voltage
should be within 10% +/- of the rating.
8. The suction lter in the tank may be clogged. Clean the lter as
described in the maintenance section.
9. A vacuum leak may be allowing air into the suction line. This will
cause the pump to cavitate (loss of suction). Check all ttings in
the suction line and replace or repair if necessary.
NOTICE
If cavitation is allows to continue, the pump will be dam-
aged and will need to be replaced.
10. If the pump or the motor has been changed for any reason, the
coupling may not have been installed.
The machine clamps and rotates but fails to hold
the load:
1. Adjust the clamping force to hold the load (See page 12).
If the steps listed above do not solve the problem, please call
the Customer Service Department at Southworth Products
Corp. [phone] or [phone].
