injury.
JOINT FORMATION
!Before using this tool, read its Operation and Safety instructions
contained in this manual.
!This tool is a single reverse notch-joint sealers. Each notch-joint
must be inspected to make certain it has two (2) good notches. A
properly formed notch-joint will appear as shown in the
illustration. If the notch-joint does not appear as shown, then the
operator must proceed as follows.
1.Make certain that the tool's operating instructions are being
followed before applying another strap.
2.Cut the strap off and apply a new strap and seal.
3.An improper formed seal which does not have two (2) good notches, could result in strap
separation. Before moving any package be certain that the seal is formed as shown.
Inspect the joint to make certain it appears as shown in the illustration. If not, remove the
broken strap and check the tool for worn or broken parts. Repair the tool for worn or
broken parts. Repair the tool before applying another strap.
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 simialr tools will cause tensioned strap to fly
apart with hazardous force. Use only cutters designed for cutting strap. Read the instructions in
the cutter's manual for proper procedures in cutting strap. Before using any Signode product
read its Operation and Safety Manual.
CLEANING & LUBRICATION
Clean and apply a light weight machine oil to all moving parts on a weekly basis. Clean the
feedwheel daily with a wire brush. Debris accumulated in the teeth of either the feedwheel or the
clutch plug must be removed with a small wire brush. A need to clean the teeth will become
apparent when either the feedwheel skids on the strap or the lower strap slips on the clutch plug
during tensioning. Refer to the Pneumatic Information shown in this manual for lubricant
recommendations with regard to the air motor.

Signode tools and machines are designed
and warranted to work together with
Signode strapping and seals. Use of non Signode strap and 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.
AIR SUPPLY INSTALLATION
If compressor has a good dryer unit, use black pickled pipe. When a dryer unit is not installed,
use galvanized or copper pipe.
To perform 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 this tool.
!Exceeding the maximum allowable air pressure could result in severe personal injury.
A filter-regulator-lubricator unit (P/N 173111) must be installed as close to the air tool as
possible, preferably within 10 feet (3M). It should be placed in a convenient location where it can
easily be drained, adjusted, and filled with oil. The air hose (P/N 008558) must have at least a
3/8" (9.5mm) I.D. A quick-connect press-on socket (P/N 008569) 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 polycarbonate. 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.
66
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, Signode Part No. 173111. Additional information is
available in the Signode publication, "Air Supply Manual" Signode 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 4 to 10 drops
per minute. This rate is to be 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 80120 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 1:1 with kerosene. 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 CONSUMPTION
Air consumption in cubic feet per minute (cfm) for the PNSC-2 can be calculated as follows:
cfm = (a)x(b)x(0.23)
a = Number of straps applied per minute.
b = Number of seconds air motor is on per strap during tensioning, from start to finish
sealing.
0.23 = PNSC-2 efficiency ratio.
Example calculation:
(a)x(b)x(0.23)=4x5x0.23=4.6 cubic ft/min.
Peak strapping load is 4 straps/minute, so a=4.
Air motor is on 5 seconds/strap, so b=5.
PNSC-2 efficiency ratio is 0.23.
Air pressure is assumed to be 90 psig with the recommended size and length of air hose.
Volume of air at room temperature and sea level pressure, or so-called "free air" conditions. For
more detailed information about air supply systems, refer to Signode manual Part No. 186038.
AIR LINE PRECAUTIONS
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.
Strap breakage hazard. 3/4" (19mm) strap can break during tensioning if inlet air pressure to
the tool exceeds 70 psig. Strap breakage can result in severe personal injury. Maximum
operating pressure is 90 psig.
88

possible.
3.While continuing to hold the tool by the motor, release
the stationary handle. Press the lever marked #1 to it's
locked position (tension) to begin tensioning the strap
around the bundle. The tool will stall when the set
tension level has been reached. If the tension is too
much or too little, the tension can be adjusted as
described elsewhere in this manual.
NOTE: If strap alignment on the package is
unsatisfactory and it becomes necessary to shut off
the tool during tensioning portion of the cycle, move
the tension lock lever to the right to allow the tension
lever to release and stop tensioning. Squeeze handle
and motor together to release tool and realign strap.

(Key 55 on page 15) clockwise. Note, do not turn the
strap tension screw more than one rotation at a time
without testing tool.
1717
TOOL MAINTENANCE
The most common reason for poor tool performance and incorrectly formed straps joints is
improper tool maintenance. The easiest way to determine if a tool is performing correctly is by
inspecting the strap joint. Having a tool maintenance program is a simple task which consists of
three parts. First, a quick daily inspection of the tool for any worn or broken parts. Secondly,
keep each tool on a schedule of service intervals for cleaning and lubrication. Third, when
problems do occur, use the troubleshooting guide to properly determine and fix problems before
they lead to more serious tool conditions. Each of these three tasks have been outlined for this
particular tool, read and understand all information for improving the life and performance of the
tool.
TOOL INSPECTION
Visually inspect the exterior of the tool on a daily basis. Decreased tool life can be prevented by
early detection of broken parts. Replace all broken parts with new parts. Review the Parts
Removal, Replacement & Adjustments portion of this manual for information and details.
SERVICE INTERVALS
This tool, like most Signode tools, can be used with various sizes of strap which cause different
rates of component wear. Also, wear is affected by the environment and tension that the tool
applies. In the worst case, heavy gauge wide strapping. All critical moving components of the
tool should be inspected at particular intervals, some more often than others. Broken parts can
decrease sealing effort, leading to additional component wear and produce lower joint strength.
Inspect the components of the sealing mechanism when:
A. Joint does not appear as shown in this manual or visually it is detected that the joint is
not all formed or formed improperly.
B. Sealing effort requires higher air pressure or tool is difficult to remove from strap.
C. When scheduled.
If there is any question that joint formation is not as shown or is
suspect, it is important that you contact your tool representative immediately.
The feed wheel and wear plug are also subject to wear and chipping. A daily cleaning of these
parts by brushing off debris will be important to maintaining long life. The first indication of wear
will be strap slippage during tensioning. The operator of the tool should be instructed on how to
determine when the strap slips during tensioning. Sometimes the teeth need to be cleaned with a
wire brush, but if slipping is allowed to continue, the parts will need to be replaced. Using the
tool in a dirty environment will increase feedwheel wear.
NOTE: On some Signode tools the feedwheel can be cleaned by holding the tool open in the
strap loading position while the tool runs without strap and using a wire brush to clean the
feedwheel as it rotates.
Inspect the components of the tensioner mechanism when:
A. Strap slips when being tensioned.
B. Evidence of feedwheel milling on the strap face.
C. When scheduled.
TOOL LUBRICATION
Signode tools use a variety of greases and oils, all of which can be ordered through Signode.
When ordering indicate tool model, part number and name.
