PNEUMATIC INFORMATION

AIR PRESSURE REQUIREMENTS

The AMPT-12 tools are designed to operate
at air pressures ranging between 65 and 90
psig (4.5 - 6.2 Bar).

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, water­free air at adequate pressure.

Never operate this tool using a
bottled air or gas source.

A filter-regulator-lubricator unit (Signode Part
No. 173111) 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 1/4" I.D. A quick­connect 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 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.

PNEUMATIC INFORMATION, Continued

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.

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.

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 portion of the F-L-R
(Part No. 173111) unit.

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.

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 non­detergent, 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.

AIR CONSUMPTION

COLD WEATHER OPERATION

Air consumption in cubic feet per minute
(cfm) for the AMPT-12 can be calculated as
follows:

cfm = (a) x (b) x (0.20)

a = Number of straps applied per minute.
b = Number of seconds motor is on per

strap during tensioning, from start to
deceleration to stall including stall
time while making joint when.

0.20 = AMPT-12 efficiency ratio.

Example Calculation:

Peak strapping load: 4 straps/min. so a = 4

Air motor run time: 5 sec./strap, so b = 5

AMPT-12 efficiency ratio is 0.20

(a)x(b)x(0.20) 6

Air pressure is assumed to be 90 psig (6.2
Bar) with recommended size and length of air
hose. Volume of air is 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.

6 4x5x0.20 = 4 cubic ft/min.

66

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 anti­freezes, 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-Regulator­Lubricator or relocate the F-L-R to a
warmer operating area.

STRAP TENSION

LOADING SEALS

The AMPT-12 tools are factory tested to
ensure that at least 350 lbs. (1554N) of
tension is drawn at 90 psig (6.2 Bar).

NOTE: Make sure the input air pressure to
the tool is set between 65 and 90 psig.

Strap breakage hazard. Strap can break
while tension is being increased. Stand
to one side of the strap as it is being
tensioned. Failure to do so could result
in personal injury.

To adjust the AMPT-58 strap tension, use the
following instrcutions:

1. Loosen the set screw on the side of the
air motor.

To load seals, raise the seal pad assembly
and insert a stack of seals inside the seal
magazine. Release the seal pad. Activate
the sealing mechanism by depressing then
releasing the sealing lever. A seal will be
ejected into the sealing jaws. An extension
on the seal pad closes the top strap loading
slot as a reminder to add seals.

2. Turn the pressure adjustment screw in
increments of 1/8 turns clockwise to
decrease strap tension and counter­clockwise to increase strap tension.

3. Turn the adjustment screw until the
desired tension level has been reached.

4. When a satisfactory tension level has
been reached tighten the set screw.

The tool is now set to operate at a given air
pressure in combination with a particular
strap size. Any change in air pressure or
strap size could result in unsatisfactory tool
performance or strap breakage.

CUTTER ADJUSTMENT

If the cutter on the tool does not cut properly,
loosen the shoulder bolt (39) and cap screw
(42), and adjust set screw (44) to remove
clearance between the cutter blade and the
cutter block. Adjust with the jaws in the
down position. Do not over tighten as the
sealing mechanism can be bound by this
adjustment. When adjustment has been
made, retighten the shoulder bolt and cap
screw.

OPERATING INSTRUCTIONS, Continued

3. The motor will stall when the pre-set tension
level has been reached. Press the sealer
lever all the way down, then release. Do not
hold tensioner lever down while pressing the
sealer lever as the tensioning lever will be
released automatically. The tool will
automatically seal the straps together, cut off
the top strap and eject a new seal into the
jaws. Inspect the joint to make sure the tool
has properly crimped the seal.

4. After the tool has sealed and the sealing
mechanism retracts, the feedwheel will
automatically raise off the straps. Swing the
rear of the tool away from the completed tie
to free the tool.

5. If the resulting tension level is not
satisfactory for your strapping needs, then proceed to adjust
the tension as described earlier in this manual.

JOINT INSPECTION

This tool has a crimp type sealer. A properly made joint will
appear as shown in the illustration. If the joint does not
appear as shown, then the operator must proceed as follows:

1. Insure that the tools operating instructions are being

followed before applying another strap.

2. Cut the strap off and apply another.

If the joint still does not appear as shown, then inspect the
tool for worn and/or damaged parts. Replace tool parts as needed.
NEVER HANDLE OR SHIP ANY LOAD WITH IMPROPERLY FORMED
JOINTS. Misformed joints may not secure the load and could
cause serious injury.

AIR MOTOR 18R36, DISASSEMBLY & REASSEMBLY

Considerable care must be used when an air motor is disassembled. Lack of lubrication and dirty
unfiltered air are the main causes of malfunctions, which are corrected by proper maintenance of
the filter, regulator and lubricator unit. Review Pneumatic Information in this manual for
installation and maintenance recommendations.

REGULATOR DISASSEMBLY:

1. Remove the motor pressure regulator parts, clean and replace if necessary.

2. Reassemble and test tool before proceeding with the Motor Disassembly.

MOTOR DISASSEMBLY:

1. Loosen cap screw (13). Loosen ring nut (20) and remove motor from tool gear housing.

2. Hold motor housing (28) lightly in a vise, and remove gear housing (29) by rotating counter-

clockwise when facing gearing end.

3. Keep groups of parts together without separating bearings unless their replacement is

necessary.

4. Wash out any dirty parts using a fresh clean oil base type solvent.

5. Rotate bearings to make certain parts are clean. Apply a light coating of grease, #K-55, non-

fluid oil, or an equivalent light cup grease. Do not apply grease on rotor (27) since this will
cause sticking of vanes (22). Do not grease bearing (3) located in back end plate (21).
Lubricate rotor, vanes and end bearing with air line oil only.

6. Replace gearing (18, 24, 27) and vanes (22) if worn or cracked. Apply a light coating of grease

to gearing and air line oil to rotor and vanes.

REASSEMBLY:

1. Begin reassembly by making certain that the alignment pin (5) is correctly positioned to align

the back-end plate (21), the cylinder (26) and the front-end plate (25) with the hole in the motor
housing (28).

2. Assemble parts (8, 11, 12, 14, 18, 19, 24) and place them in the gear housing (29). Make certain

that the roll pin (12) enters into the slot of the ring gear (19).

3. Assemble the gear housing (29) and the ring nut (20) to the motor housing (28). Hand tighten.

Rotate the pinion of the gear case (24) by hand in the clockwise direction to be certain all parts
are free. If parts are not free, gears are not properly meshed.

4. Add one teaspoon or squirt air line lubricating oil into the motor. Connect the air hose with

the pressure set at approximately 20 p.s.i.g. With motor housing in vise, slowly tighten gear
housing in a clockwise direction while the motor is rotating. Tighten the motor, noting an
increase in speed. The correct adjustment is about 400-600 inch lbs. If the motor is over
tightened it will slow down. When set, attach the air motor to the gear housing.

TROUBLESHOOTING, Continued

#2 CONDITION: Air motor runs slowly or sluggishly.

CAUSE REMEDY

1. Air supply to tool is restricted.

1A. Check gauge on FRL for proper 65-90

psig pressure setting.

1B. Check air line from FRL for blockage
1C. Check for satisfactory air volume

reaching tool by either of the following
methods:

a. Install an in-line air gauge at the tool if

one is available. Hook up air and record
pressure reading. With no strap in tool,
press tension lever and record gauge
reading. If pressure drops more than 15
psig, air supply is inadequate. Remedy
is to improve air flow by shortening
length of line from FRL to tool,
increasing size of air lines, or checking
for obstructions to or from FRL unit.
Example: If piping system equipped
with shutoff valves, ensure valve are
fully open.

b. If no in-line gauge available, repeat step

"a", above, except use gauge on FRL
unit.

2. Air motor filter screen is blocked with
rust or dirt.

3. Air motor is dry, unlubricated, causing
motor to run slowly.

2. Check air motor filter screen for
obstruction then clean or replace as
required.

3. Add teaspoon air line oil directly into
the motor at elbow. Place rag around
motor, reconnect air and test. If motor
speed increases, motor was dry. Check
lubricator for proper adjustment,
quantity and type of oil.

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 the gripper teeth 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 and gripper plug 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 tensioning.
B. Evidence of feedwheel milling on the strap face.
C. When scheduled.
