during tensioning, which could result in the following:
!A sudden loss of balance causing you to fall.
!Both tool and strap flying violently towards your face.
Failure to place the strap properly around the load or an unstable or shifted load could result
in a sudden loss of strap tension during tensioning. This could result in a sudden loss of
balance causing you to fall.
!If the load corners are sharp use edge protectors.
!Positioning yourself in-line with the strap, during tensioning and sealing, can result in
severe personal injury from flying strap or tool. When tensioning or sealing, position
yourself to one side of the strap and keep all bystanders away.
2. TRAINING.

Use the correct Signode products for your application. If you need help contact your
Signode Representative.
Signode tools and machines are designed and warranted to work together with Signode
strapping and seals. Use of non-Signode strap, seals and/or manufactured or specified
replacement parts may result in strap breakage or joint separation while applying strapping
to a load or during normal shipping and handling. This could result in severe personal
injury.
JOINT FORMATION
An improperly formed joint, or a joint with an incorrect number of notches, could result in strap
separation. Before moving any package, be certain that the joint is formed as shown in the
illustration. If not, remove the strap and check the tool for worn or broken parts. Repair the tool
before applying another strap. Failure to follow this procedure could
result in serious injury or death. If you have questions regarding proper
joint formation, contact your Signode Sales Representative.
Before making a double reverse notch seal joint, read the sealing tool’s
Operation. Parts and Safety Manual. A properly formed double reverse
notch joint will appear as shown in the illustration. More than one seal
may be required for your application. Always uses the correct number
of seals recommended by your Signode Sales Representative.
If the double reverse notch joint does not appear as shown in the
illustration proceed as follows:
1. Review the tool’s operating instructions to be certain that the tool is being operated
properly before applying another strap.
2. Cut the strap off, and apply a new strap and seal.
MOVING AND STACKING STRAPPED LOADS
Before moving or stacking any strapped load, follow all standard industry practices regarding
safe material handling procedures.
CUTTING TENSIONED STRAP
Using claw hammers, crowbars, chisels, axes or similar tools will cause tensioned strap to fly
apart with hazardous force. Use only cutters designed for cutting strap. Read the instructions in
the cutters manual for proper procedure in cutting strap. Before using any Signode product read
its Operation and Safety Manual.
TOOL CLEANING & LUBRICATION
Clean and apply a light weigth machine oil to all moving parts on a weekly basis. Clean the
feedwheel daily with a wire brush. Refer to the Pneumatic Information shown in this manual for
lubricant recommendations with regard to the air motor.

TOOL INSTALLATION
To work effectively, the PRHR Tool must be properly installed. This installation includes, in
some cases, proper suspension of the tool over the container to be strapped and the proper
placement of the strapping dispenser to provide a continuous easy supply of strapping for the
application.

MAJOR COMPONENTS
To better operate the PRHR become familiar with the major components of the tool.

PNEUMATIC INFORMATION
Air Supply Installation
If the compressor has a good dryer unit, use black pickled pipe. When a dryer unit is not
installed, use galvanized or copper pipe.
To preform reliably, a pneumatic tool requires a continuous source of clean, water-free air at
adequate pressure.
Never operate this tool using a bottled air or gas source.
Bottled air/gas sources do not provide consistent operating pressure and
could result in air pressures that exceed the maximum allowed for the tool.
A filter-regulated-lubricator unit (Signode Part No. 008559) must be installed as close to the air
tool as possible, preferably within 10 feet. It should be placed in a convenient location where it
can easily be drained, adjusted, and filled with oil. The air hose must have at least a 3/8" I.D.. A
quick-connect press-on socket is installed on the stress spring end of the hose for convenient
hookup to the air tool.
Filter and lubricator bowls are made of polycarbonate material. Do not install where bowls may
be exposed to materials incompatible with poly carbonate. Certain oils, solvents, and chemicals
or their fumes can weaken these bowls and possibly cause them to burst. Clean only with warm
water. A cut-off valve placed ahead of the filter will be useful when cleaning the filter or
replenishing the lubricator.

7
MOISTURE
Moisture is always present in air lines due to condensation within the lines as the air cools.
Steps must be taken to remove this moisture and to keep it from the air tool. This is because
water tends to wash away lubricants and cause corrosion, sticking and failure of internal parts.
The main line should be pitched so the far end terminates in a water leg. Branch lines are taken
from the top of the main, never off the bottom. Every branch should have a water leg at its
lowest point, with a drain cock which is drained daily.
If these precautions are taken and water is still present, an after cooler and a moisture separator
are required between the compressor and the air receiver tank. A large air line separator can be
installed in the air tool line, but precautions must be taken to insure that it will be drained daily,
before the air tool is operated.
Water in air lines is a constant threat to the proper operation of air tools. Even near freezing
operating conditions, a good refrigerant type dryer is essential. A good dryer will remove 95%
or more of water right at the compressor. The remaining moisture is removed at the water leg in
the piping system or in the filter (Part No. 173111).
NOTE: Additional information is available in the Signode publication, "Air Supply Manual" (Part
No. 186038). If you have any questions, contact your local Signode Representative.
LUBRICATION
The air motor must be properly lubricated. This is achieved by keeping the air line lubricator
filled with oil and correctly adjusted. Without proper lubrication, the motor will become sticky
and the tool will give low and erratic tension and be difficult to release from the strap.
Install the lubricator as close to the air tool as possible. The arrow on the lubricator's top
surface must point in the direction of air flow. For proper operation, oil must drop through the
lubricator sight glass at a rate of 1 to 4 drops per minute. This rate is checked while the air tool
is running free. Only 20% of this oil is actually delivered to the tool. The remaining oil drops
back into the oil reservoir. The unit is factory set and should require no adjustment. If an
adjustment is required, the adjusting screw on top of the lubricator may be turned as marked to
reduce or increase the flow of oil.
The correct grade of oil must be used in the lubricator; too heavy an oil will not provide sufficient
lubrication and will cause sticking and sluggish operation of the air tool. Recommended oils are
any good grade of rust and oxidation inhibiting oil with a viscosity of 80-120 S.U.S. at 100
degrees Fahrenheit. (0.15 to 0.25 cm2/sec. at 38 degrees Celsius), such as:
Non Fluid Oil Co., grade #LS-1236 Signode oil - Part No. 008556
If necessary, use SAE #5 or SAE #10 non-detergent, cut 1 to 1 with kerosene.
NOTE: Some oils contain anti-wear additives which may disable the air motor. Be certain to use
recommended oil.
Several drops of lubricator oil added to the inlet of the air motor or into the air line each day will
help insure good operation. A noticeable reduction of air motor performance can usually be
corrected by squirting a few drops of oil into the air line.

PNEUMATIC INFORMATION, Continued
COLD WEATHER OPERATION
If a tool does not operate satisfactorily in freezing temperatures, certain steps can correct the
problem. The following steps can be taken to improve cold weather operation of the tool:
a. An air line dryer adjacent to the compressor.
b. Use lubricant recommended by Signode. Signode has tested the use of anti-freezes, none
work well in air tools; the tool will gum up when anti-freezes are introduced and will not
function properly. The best lubricant for freezing weather is the 1 to 1 oil and kerosene
combination.
c. If possible, run the air supply line to a indoor located Filter-Regulator-Lubricator or relocate
the F-L-R to a warmer operating area.
AIR PRESSURE vs. STRAP TENSION
A minimum air pressure setting of 70 psig must be maintained to ensure that the tool will seal
properly. Input air pressure to tool must not exceed 90 psig. Strap tension is controlled by air
pressure. Use the proper air line piping and lubrication as specified in this manual. Your air
pressure gauge must be accurate, therefore, confirm its accuracy by comparing it to a calibrated
master gauge.
Adjust the pressure regulator to achieve the tensions listed below. Once the regulator is set, the
tension levels will be consistent on all straps, provided the operator allows the air motor to stall.
If the air pressures do not result in tension levels that satisfy the needs of the application, then
increase the air pressure in increments of 5 psig until the desired tension level has been
achieved.
STRAP TENSION
Strap breakage hazard. Increasing the tension can result in strap breakage. 1-1/4" Strap can
break during tensioning if inlet air pressure exceeds 90 psig (6.1 BAR). Maximum operating
air pressure is 90 psig (6.1 BAR). Never remove the adjusting screw from the tool with the
air connected. The screw could become a flying projectile. Failure to follow the above could
result in serious personal injury.
Strap tension is accurately controlled by air pressure to the tool and the setting of the adjusting
screw. Once the desired inlet air pressure and the adjusting screw settings have been
established, tension will be uniformed on all straps.
The PRHR tool has been factory adjusted to draw 1400 lbs. (6216 N) of tension at 90 psig (6.1
BAR). A minimum of 70 psig (4.8 BAR) is required to ensure that the tool will seal properly.
To adjust the tension:
1. Make sure the air pressure is set between 70 and 90 psig (4.7 an 6.1 BAR).
2. Loosen the hex nut (81) and turn the adjusting screw (80) clockwise to decrease tension and
counterclockwise to increase tension.
3. Retighten the hex nut.

OPERATING INSTRUCTIONS
Wear safety glasses which conform to ANSI Standard Z87.1 or EN 166.
Stand to one side of the strap while tensioning.
Make sure all bystanders are clear before proceeding.
Failure to follow the above could result in serious personal injury.
STRAP AND SEAL LOADING
Refer to the Specifications section to make sure the seal has been chosen. Insert the lead end of
the strap into the seal Signode No. 114P.
Pass the strap over the top of the package then bring the lead end around and up and rethread it
into the seal. This will result in creating a TOP STRAP and a BOTTOM STRAP. They will be
referred to later in these instructions.
Bend about 2 1/2" (63.5mm) of the lead end of the BOTTOM STRAP back beneath the seal to
maintain the loop. Refer to Figure 1 to make sure the loop has been properly formed. Hold the
BOTTOM STRAP and pull back on the TOP STRAP to draw loop loosely around the package. A
gentle upward bend on the TOP STRAP will hold the loop in place while the PRH2 tool is being
positioned.

OPERATING INSTRUCTIONS, Continued
CYCLING THE TOOL
1. Grasp the TOP STRAP and insert it sideways
into the tool between the feedwheel and the
breaker foot. Make sure the strap is in full
contact with the inside surface of the breaker
foot. When the TOP STRAP is properly loaded,
the sealing mechanism will be in line with the
seal.
2. Push the tool forward until the seal-stop
contacts the end of the seal.
Pull
back on the TOP STRAP to eliminate additional
slack around the package. You will have to
push on the cylinder cover to make certain that
the jaw tips are in position over the seal.
Note: Before continuing, make sure the TOP STRAP and the seal is still in position, as
described above. Note that the BOTTOM STRAP will be positioned in the channel on the
bottom surface of the breaker foot. This too, is necessary to maintain strap alignment during
tensioning.
3. While standing to one side of the strap, press
the operating lever all the way down and then
release it.
The air motor will turn the feedwheel and the
feedwheel will tension the strap around the
package until the present tension level has
been reached, at which time the air motor will
stall.

11
4. If strap alignment is unsatisfactory and it
becomes necessary to shut off the tool during
the tensioning portion of the cycle, push down
on the stop lever.
5. Press down on the operating lever once again.
Air will be routed to the sealing mechanism to
notch the seal/strap, cut-off the TOP STRAP and
raise the feedwheel to allow the tool to be
removed from the completed tie.
Lift the PRHR tool from the tie and closely
inspect the joint to make sure the tool has
properly notched the seal.
JOINT FORMATION
An improperly formed joint, or a joint with an incorrect number of notches, could result in strap
separation. Before moving any package, be certain that the joint is formed as shown in the
illustration. If not, remove the strap and check the tool for worn or broken parts. Repair the tool
before applying another strap. Failure to follow this procedure could result in serious injury or
death. If you have questions regarding proper joint formation, contact your Signode Sales
Representative.
Before making a double reverse notch seal joint, read the sealing tool’s Operation. Parts and
Safety Manual. A properly formed double reverse notch joint will appear as shown in the
illustration. More than one seal may be required for your application. Always uses the correct
number of seals recommended by your Signode Sales Representative.
If the double reverse notch joint does not appear as shown in the
illustration proceed as follows:
1. Review the tool’s operating instructions to be certain that the tool
is being operated properly before applying another strap.
2. Cut the strap off, and apply a new strap and seal.
