STRAP BREAKAGE HAZARD
Improper operation of the tool or sharp corners on the load can result in strap breakage 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 os 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.
TRAINING
This tool must not be used by persons not properly trained in its use. Be certain that you receive
proper training from your employer. If you have any questions contact your Signode
Representative.

Use 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 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.
JOINT FORMATION
! Before using this tool, read its Operation and Safety instructions contained in this manual.
! This tool is a double notch type sealer. Each notch-joint must be inspected to make certain it
has four (4) good notches. A properly formed notchjoint 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 four (4) 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 similar 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.
MAINTENANCE
Clean and apply a light weight machine oil to all moving parts on a weekly basis. Clean the

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.
LOADING SEALS
To load seals, raise the seal pad to the top of the magazine and insert a stack
of seals through the wide opening in the side of the seal magazine.
Make sure the seal stack is pushed all the way in. Seals can be
loaded at any time without waiting for seals to run out. Break a
stack and load as many or as few as needed.
APPLYING A STRAP
1. Encircle the package with the strap. Grasp the
handle of the tool and the tensioner handle with
your left hand. Squeeze the handles together to lift
the feedwheel. Place the strap in the tool so that it
is beneath the fixed cutter blade and the lead end of
the strap covers the gripper plug. Press the thumb
latch to release the rear gripper to hold the bottom
strap in place.
2. Pull out excess slack in the strap. Insert the top
strap above the fixed cutter blade and then insert it
sideways into the strap latch.
3. While standing to one side of the strap line, move
the tensioner handle back and forth, as shown.
Repeat this action until the desired tension is
obtained. Complete the cut-off and sealing
operation by pushing the sealer handle to its
maximum forward position. The rear gripper
automatically opens during this operation. NOTE:
The tensioner handle can be used to help stabilize
the tool during the sealing operation if its pulled
back as the sealer handle is being pushed forward.
The pin that protrudes from the tensioner handle
contacts the sealer plate to prevent the tool from
tipping forward and damaging soft packages.

DISASSEMBLY OF TOOL:
1. Remove the seals from the magazine and the sealer mechanism.
2. To remove both units loosen the cutter adjustment screw (33) and remove the top and
bottom cap screws in the sealer frame (1 and 2).
3. Push the magazine out to the side so the locating lug clears the offset in the frame. Pull
back the entire sealer mechanism and magazine assemblies, twisting the front outward away
from the sealer frame. Remove both assemblies from the sealer frame.
4. The magazine is now easily separated from the sealer mechanism. The magazine and sealer
mechanisms are now accessible for examination and replacement of worn or broken parts.
The sealer mechanism is serviced by removing the cutter blade pins and cutter blade. Clean
the parts. Jaws and notchers are replaced as required. Note that the outer jaws can be
reversed front to back to provide new cutting edges, doubling the life of these parts. After
necessary repairs have been made, grease the parts or apply light machine oil. The tool is
now ready for reassembly.
REASSEMBLY OF TOOL:
1. Place the sealer mechanism against the magazine and hold the units together.
2. Be sure the strap latch spring (26) is in the correct position in the tensioner frame (23).
3. Insert the lower portion of the assembly into the tool first and hook the slot in the sealer cam
(70) on to the cam roller (7) inside of the sealer frame. Then swing the front of the sealer
mechanism into the sealer frame so that the guide on the jaw support (76) aligns with the
groove in the front of the sealer frame. Then push the whole assembly forward into place
engaging the lug in the side of the magazine into the offset in the sealer frame.
4. Insert and snug up but do not tighten the top and bottom cap screws (1 and 2).
5. With jaws in the down position, advance the cutter adjustment set screw (33) until a slight
bind can be felt when operating the sealer handle.
6. Securely tighten the top and bottom cap screws (1 and 2).
7. Insert a stack of seals into the magazine. Operate the sealer mechanism through 3 or 4
cycles to check tightness of the cutter adjustment set screw and see that the seals feed
properly. If the sealer mechanism is excessively tight, back off the cutter adjustment set
screw slightly. Next, apply a strap under tension to be sure that all elements of the tool
operate properly.
EJECTOR (48) AND EJECTOR LEVER (46) W/O MAGAZINE REMOVAL:
