PNEUMATIC INFORMATION
AIR PRESSURE REQUIREMENTS
The VT tools are designed to operate at an air pressure of 90 psig (6.2 Bar).
AIR PRESSURE VS. PERFORMANCE
The air pressure supplied to the VT tool must be a minimum of 85 psig (5.7 Bar) If the air supply
pressure can be adjusted within a range from 85 psi to 90 psi (5.7 - 6.2 Bar) the VT tool's
performance can be fine tuned to a particular application or operation preferences. Changing the
VT air supply pressure to the tool will directly alter the rate at which the tool will take-up the strap
slack and the strap tension. Increasing or decreasing the VT air supply within the suggested 85 to
90 psig (5.7-6.2 Bar) range will not seriously affect the actual welding portion of the strap cycle.
After an initial "Break-In" period, the air motor may become more powerful. If the tool's
performance is effected by this increase in performance, reduce the air motor output by turning
the adjustment screw (Key 98) clockwise as required.
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.
A filter-regulator-lubricator (FRL) unit
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 1/2" I.D. A quick disconnect
socket fitting 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.
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 tool. 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. 008559).
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
NOTE: Some oils contain anti-wear additives which may disable the air motor. Be certain to use
recommended oil.
7
Page 8
PNEUMATIC INFORMATION, Continued
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.
STRAP TENSION
Strap tension is controlled by turning the adjustment screw
(Key 98) as shown by arrow, in 1/4 increment turns counterclockwise to increase strap tension and clockwise to reduce
strap tension.
NOTE: Operating air pressure must be set between 85 and 90
psi (5.7-6.2 Bar). With accurately controlled air pressure the
tension will be uniform on all straps, provided the operator
allows the air motor to stall.
Strap breakage hazard.
Strap can break if inlet air pressure to tool exceeds 90 psig (6.2 bar).
Strap breakage can result in severe personal injury.
Maximum operating air pressure is 90 psig (6.2 bar).
AIR CONSUMPTION
Air consumption in cubic feet per minute (cfm) for the VT can be calculated as follows: cfm = (a) x
(b) x (0.40)
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.
0.40 = VT efficiency ratio.
Example Calculation: Peak strapping load is 4 straps/min. so a = 4
Air motor is on 5 seconds/strap, so b = 5
VT efficiency ratio is 0.40
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.

Page 9
COLD WEATHER OPERATION
Signode pneumatic powered tools operate reliably in a wide range of operating temperatures.
However, operating conditions below an ambient temperate of 41°F (5°C) may require the
compressed air to be dried. Dried air typically avoids any moisture and freezing tool issues.
Air motors typically use air compressed from 70 psi to 90 psi (4.8 to 6.2 Bar) and exhaust the
compressed air approximately at 15 psi (1 Bar). The highly compressed air cycled through the
tool, then exhausted to atmospheric pressure, may result in the discharged air freezing. Freezing
air will contribute to reduced motor and tool performance.
Freezing air (icing) is a problem to all compressed air driven motors. Factors which can
contribute to icing are:
•Compressed air vs. ambient air temperatures.
•Compressed air vs. ambient air dew points.
•Compressed air pressure.
•Flow rate of the compressed air exhausted through tool.
•Contaminated air quality.
•Cycle rate of tool.
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. Use of 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 tool; the tool will gum up when anti-freezes are introduced and will not
function properly.
c. If possible, run the air supply line to a indoor located Filter-Regulator-Lubricator or relocate
the F-R-L to a warmer operating area.
d. Eliminate any air line restrictions (review “Air Supply Installation” in this manual).

AIR PRESSURE DROP
Confirm air pressure calibration by comparing it to a
master gauge placed in-line where the quick
disconnect fitting attaches to the tool.
Air pressure at the tool can then be monitored as
the tool cycles. Use the following information
shown on the chart below for comparing the various
minimum air pressures while the VT tool cycles.
If pressure readings fall below the minimums, inspect your air supply system as well as the tool
for worn and/or broken parts. Contact your Signode representative if you have any questions.

VT STRAP SIZE CONVERSION
NOTE: All parts named below to convert a VT tool can be found in the original shipping box.
Use th following instructions to convert (or reconfigure) a tool from 16mm strap to 19mm or vice
versa.
1. The two inner guides (Key 73) must be reversed. Remove the mounting screw (Key 23) and
reposition the guide so that the strap contact surface marked “16" or “19" is facing the strap
path. Use Loctite #242 (or equivalent) when reinstalling the mounting screws.
2. The outer guide (Key 109) must be exchanged with the appropriate guide for the strap size
(Signode P/N 423956 for 16mm and P/N 423957 for 19mm). Guides can be identified by the
outer surface being marked “16" or “19". Remove the guide’s mounting screw (Key 23) and
install the proper guide. Use Loctite #242 (or equivalent) when reinstalling the mounting
screw.
3. The guide plate (Key 86) must be exchanged with the appropriate guide plate for the strap size
(Signode P/N 423978 for 16mm and P/N 423979 for 19mm). Guide plates can be identified by
the outer surface being marked “16" or “19". Replace the guide plate by first removing support
bar (Key 54) which is secured by two mounting screws (Key 4).
NOTE: The support bar fits tightly into the tool. Exercise care when removing so as not to
cause any binding from end to end as it is removed.
Continue to remove the outer link (Key 60) and the existing guide plate (Key 86) at the same
time.
4. Install the appropriate guide plate and outer link together as the parts are positioned on the
tool. Reinstall the support bar making sure that the alignment pin (Key 95) installs into the slot
of the new guide plate.
5. If desired, the tool nameplate may also now be exchanged to display the appropriate strap size
(Signode P/N 423987 for VT-16 and P/N 423988 for VT-19).

OPERATING INSTRUCTIONS
Wear safety glasses. Stand to one side of the strap when tensioning.
Make sure all bystanders are clear before proceeding.
PLEASE NOTE: Do not operate tool without strap, as damage to the tool may occur.
1. With the dispenser placed
behind you, bring the strap over
the top and around the package,
place the straps together and
remove any excess slack.
2. Using your right hand, squeeze
the tension motor and stationary
handle together to open the
feedwheel and strap path. Using
your left hand, insert the
overlapped straps under the
feedwheel and through the
welding mechanism.
Leave only a short tail ahead of
the feedwheel and make sure
straps are aligned behind the
tool. Do not make a joint over a
void area of the package.
12
Page 13
3. Recheck the strap alignment at
the rear of the tool and realign if
necessary. Release the tension
motor.
Press down the Green Tension
Control Lever to begin
tensioning the strap.
When the tension motor stalls, indicating completion of tension, release the control lever. The
strap will remain tensioned around the package.
NOTE: If the strap alignment is unsatisfactory or the tool needs to be removed before sealing.
Remove the tool as described in Step 5 of these instructions.
4. Press the Blue Sealer Control
lever to begin the sealing cycle.
It is not necessary to continue
holding the lever down once
the weld cycle has started.

Page 14
OPERATING INSTRUCTIONS, Continued
5. The internal weld timer is
energized. The main piston
brings the welding pads
together and the strap is
welded.
The supply end of the strap is
then cut off. Pull the cut strap
away from the tool during
welding. The tool will continue
through the weld cycle and stop
automatically.
5. When the weld cycle has completed the weld mechanism slowly returns to the neutral
position. This allows the newly welded strap joint to cool down properly. The tool can be
easily removed once the weld mechanism has completely returned to the neutral position.
NOTE: The weld
mechanism’s return to the
neutral position can be
identified by the indicator
located on the top of the
tool. When the indicator is
in the down position the
weld mechanism is still
engaging the strap. When
the indicator is in the up
position the weld
mechanism has returned to
the neutral position. The
INDICATOR IN THE UP POSITION
(NEUTRAL)
tool can then be easily
removed from the strap.
Remove the tool from the strap by first lifting
up the tension release lever found on the
bottom of the gear housing while squeezing
the tension motor and stationary handle
together to open the strap path.
INDICATOR IN THE DOWN POSITION
(ENGAGED)
NOTE: Failure to wait for the weld mechanism to return to the neutral position may lead to an
improperly formed joint which may lead to joint separation and make tool removal difficult.
14
Page 15
6. Swing the tool out from the
completed strap joint. Inspect
the joint to make sure the straps
have been properly welded.
STRAP JOINT INSPECTION
This tool is a Tension Weld® 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 tool operating instructions are being followed before applying another
strap.
2. Cut the strap off and apply another.
A good weld will show some material displacement along
the edges. The welded area should extend the full length
and width of the gripper impression.
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.

TOOL ADJUSTMENTS
WELDING TIME
Weld time has been factory adjusted to provide acceptable weld strength when using High
Strength Tenax (polyester) type strap. Weld time may need to be adjusted due to air supply
differences, tool wear, etc. Adjustments are made by turning the adjustment screw, located on the
cover plate, using a small screwdriver. Turn the screw clockwise to increase weld time and
counterclockwise to decrease weld time.
Establishing the correct weld time is a matter of trial and error and should be conducted as
follows.
1. Remove the cap which protects the
adjustment screw. Adjust the screw in 1/8 to
1/4 turn increments only.
2. Apply a strap and make a weld.
3. Compare the weld made with the illustrations
shown on page 13 of this manual. A good
weld will displace some material along the
outer edges of the joint.
4. If you are unable to produce an acceptable
joint or if you have any questions as to
whether your tool is producing good weld
strength, contact your Signode Sales
Representative.
5. Replace the cap over the screw.
LOCATION OF WELD TIME ADJUSTMENT
WELD COOLING TIME
Cool time has been factory adjusted to allow the proper time for a weld to properly cool. The cool
time adjust controls how fast or slow the main piston bleeds off air pressure allowing the weld
pads to separate from one another.
Cool time may also need to be adjusted due to air supply differences, tool wear, etc. Adjustments
are made similar to weld time. Turning the screw clockwise increases cool time and
counterclockwise to decrease cooling time.
Establishing the correct cool time is a matter of trial and error and should be conducted as
follows.
1. Remove the cap which protects the
adjustment screw. Adjust the screw in 1/8 to
1/4 turn increments only.
2. Apply a strap and make a weld.
3. A properly adjusted cool time should allow the
strap joint to cool for approximately two to
three seconds.
NOTE: Cool time which is too short may lead
to strap joint separation.
4. Replace the cap over the screw.

FEEDWHEEL TO GRIPPER PLUG
The feedwheel to gripper plug clearance may require readjustment if the feedwheel or gripper plug
has been replaced. The feedwheel clearance should also be inspected during routine tool
maintenance procedures. Adjust the feedwheel clearance as follows:
1. Squeeze the tension motor and stationary handle
together to open the feedwheel gap. Place multiple
(4 to 8) layers of .002", 1/2" wide (.05 x 12mm) shim
stock between the feedwheel and the gripper plug.
NOTE: Do not use a single shim such as .008"
(.20mm) as thicker shims may not conform to the
feedwheel shape, resulting in inaccurate clearance
measurements.
2. Release the tensioner motor to pinch the shims
between the feedwheel and the gripper plug.
Holding the shims with one hand, jog the tension
motor on and off to rotate the feedwheel at least one
full revolution. If properly adjusted the tool should
lightly tug at the shims while rotating. Clearance between the feedwheel and gripper plug at
this point should fall between .008" to .016 (.20mm to .40mm).
3. If the feedwheel needs to be adjusted, use a 3mm hex
wrench to turn the adjustment screw which can be
accessed through the bottom of the tool base.
Turn the adjustment screw clockwise for greater
clearance and counter-clockwise for less clearance.
Turn the adjustment screw only in 1/8 turn increments.
After each 1/8 turn, repeat the adjustment testing as
described in step 2.
4. Once the proper clearance has been found the tool
can be returned to service.
NOTE: Never turn out the adjustment screw more than
1/8 turn at a time without testing or completely remove
the adjustment screw. These actions will severely
damage both the feedwheel and gripper plug.
STRAP TENSION
Strap tension is controlled by turning the adjustment
screw (Key 98) as shown by arrow, in 1/4 increment turns
counter-clockwise to increase strap tension and clockwise
to reduce strap tension. Use the 4mm hexwrench (Signode
Part No. 274467) included with every new tool.
NOTE: Operating air pressure must be set between 85 and
90 psi (5.7-6.2 Bar). With accurately controlled air pressure
the tension will be uniform on all straps, provided the
operator allows the air motor to stall.

TOOL ADJUSTMENTS, Continued
STRAP CUTTER
The VT strap cutter has two serrated cutting edges.
After the first edge has become dull or strap cut-off
becomes difficult the blade can be remounted to use
the second cutting edge. Once both edges have
become worn the blade should be replaced. Use the
instructions below to remount, install and adjust a
new cutter blade.
1. Remove the two mounting screws which secure
the air motor to the tool body. Remove the weld
motor from the tool by turning the motor counterclockwise to release the O-ring which seats on
the top of the motor.
NOTE: The small spring contained in the holder does not need to be removed to change
the cutter blade.
2. The cutter blade group of parts can now be removed from the tool. Continue to also remove
the cutter pin from the tool.
3. Remove the two smaller screws which mount the cutter blade to the holder. Rotate the cutter
blade to the new cutting edge and reinstall the mounting screws.
NOTE: If both cutting edges are worn replace the cutter blade at this point.
4. Reinstall the cutter group of parts back into the tool. Before installing the cutter pin inspect
the cutter holder movement within the tool.
A. The holder should move freely up and
down in the tool body. If the holder does
not move freely inspect the tool for debris
or damage.
NOTE: If the holder has been replaced
it may be necessary to adjust the set
screw which controls the side clearance.
B. The holder should not be able to move
from side to side. Excessive side to side
clearance will result in poor strap cut-off. If
the holder does move side to side, tighten
the set screw until it just touches the side
of the holder, approximately a 0.025mm
(0.001") clearance.
5. Once the cutter holder has been inspected and adjusted, continue to reinstall the remaining
parts in the order that they were removed.
6. Run a few test cycles on the tool to confirm that the strap cut-off performs properly.

TROUBLESHOOTING, Continued
#3 CONDITION: The tool runs sluggishly.
CAUSEREMEDY
1. The air filter-regulator-lubricator is
malfunctioning or is not properly maintained.
2. The tool may run sluggishly due to a clogged or
dirty motor filter screen due to a lack of properly
filtered air supply.
3. The tool may run sluggishly due to an improper
air motor adjustment or a clogged or dirty
vibrator assembly.
4. The end plates, pinion teeth on the rotor and the
rotor blades are worn, dirty or rusted.
1A. Check the regulator to see that the correct air
pressure is getting to the tool.
1B. Check to see the filter unit is clean and
functioning properly.
1C. Examine the lubricator to see there is oil in the
bowl and that oil is seen dripping from the sight
dome as the tool operates. This assures the air
motor is being properly lubricated.
2.Remove the Hansen plug at the inlet to the air
motor and examine the filter screen in the filter
assembly and clean it if necessary.
3.Clean vibrator parts as needed. Inspect vibrator
eccentric for wear or damage. Replace as
required.

another by an inside shoulder on each part, it is
not often these parts have to be replaced.
3.Review the operating instruction shown in this
manual.
28
Page 29
#6 CONDITION: A poor weld identified by an incomplete area of weld.
CAUSEREMEDY
Welding is achieved by a combination of vibration and
downward pressure of the upper gripper. Either a
restriction of motion or a reduction of downward
pressure will cause a poor weld.
#7 CONDITION: Incomplete or no weld.
CAUSEREMEDY
1. Improperly set weld time adjustment.
2. Worn teeth on upper or lower weld pads.
3. Insufficient air supply pressure.
4. Worn o-ring on main piston.

OVERHEAD SUSPENSION
To work effectively, your VT 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 a strapping dispenser to provide a continuous easy supply of strapping for the application. The
VT can be suspended in various operating positions by using the proper tool hanger and
hardware.
Review the illustrations below for the appropriate configuration for the tool application.
Applications are recommended to use an Overhead Tool Balancer as shown (Signode Part No.
306809).

TOOL OPTIONS
TENSION LATCH KIT, 424760
This option makes the VT tool easier for the operator to
use. The tension control lever only needs to be pressed
one time to fully tension a load. This option eliminates the
need to hold down the tension control for the entire tension
cycle. Once the tool’s sealer control in engaged the tension
latch automatically releases and resets.
This option allows the operator to suspend the VT tool
from its side to allow for easier horizontal strapping
applications as well as top and side sealing applications.
The hanger replaces the standard VT tool hanger.
NOTE: Hanger is supplied with additional M5x16 socket
head cap screws (Part No. 170304) for mounting the
hanger to the tool.
HEAVY DUTY TOOL BASE, 424763
This optional tool base replaces the standard base of the
VT tool. The heavy duty base is recommended for
increasing tool life in rough operating conditions. This part
is replaced using the existing mounting hardware of the
standard tool base.

OPTIONAL WEAR RING, 424756
An optional wear ring is available to protect the tension motor
from harsh operating environments. This wear ring can be used
with either the VT-16 or the VT-19 tools. To install the wear ring
spread open the ring gap using an appropriate spreading tool.
Begin to slip the ring over the end of the tension motor. Using a
rubber mallet, gently tap the wear ring down onto the end of the
air motor.
OPTIONAL MOTOR GUARD, 425225
An optional motor guard is available to protect the
motor gear housing from harsh operating
environments. This motor guard can be used with
either the VT-16 or the VT-19 tools. Install the
motor guard to the bearing cap using two M5 x 8
button head cap screws. The white tension piston
