READ THESE INSTRUCTIONS CAREFULLY.
FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT IN SEVERE PERSONAL INJURY.
GENERAL SAFETY CONSIDERATIONS
1.
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 of strap tension during tensioning. This could result in a sudden loss of
balance causing you to fall.
Read the tool's operating instructions. If the load corners are sharp use edge protectors.
Place the strap correctly around a properly positioned load.


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.
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.
3.
EYE INJURY HAZARD.
Failure to wear safety glasses with side shields can result in severe eye injury
or blindness. Always wear safety glasses with side shields which conform to
ANSI Standard Z87.1 or EN 166.
4.
FALL HAZARD.
Maintaining improper footing and/or balance when operating the tool can cause you to fall. Do
not use the tool when you are in an awkward position.
5.
CUT HAZARD.
Handling strap or sharp parts could result in cut hands or fingers. Wear protective
gloves.
6.
TOOL CARE.
Take good care of the tool. Inspect and clean it daily, lubricate it weekly and adjust
when necessary. Replace any worn or broken parts.
7.
WORK AREA.
Keep work areas uncluttered and well lighted.

3
8.
OPERATING SEQUENCE.
Use the correct Signode products for your application. If you need help contact your Signode
Representative. Before using this sealless tool, read the Operation and Safety Instructions
contained in this manual.
9.
JOINT FORMATION
Sealless joints are formed when overlapping straps are punched simultaneously creating
interlocking keys. However, the integrity of the joint is obtained when the keys punched in the
upper strap move in relation to the keys on the bottom strap, allowing the straps to interlock.
The movement necessary to create the interlock comes from the strap tension release where
the top strap moves one direction and the bottom strap moves in the other direction.
Therefore, never attempt to make a sealless joint without having the straps under tension.
This tool is a punch type sealer. A properly formed joint will appear as shown in the
illustration. If the joint does not appear as shown,
then the operator must proceed as follows:
A.
Ensure that the tool's operating instructions are
being followed before applying another strap.
B.
Ensure that tension has been applied to the
straps before the sealer handle is activated.
Tension is necessary to ensure that the keys fully interlock.
C.
After confirming the above 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.
Always tuck the strap end back into the dispenser when not in use.
10.
CUTTING TENSIONED STRAP
Using claw hammers, crowbars, chisels, axes or similar tools can cause tensioned strap to fly
apart with hazardous force. Use only Signode cutters designed for cutting strap such as the
Model CU-30. Read the instructions in the cutter's manual for proper procedure in cutting
strap. Before using any Signode product read its Operation and Safety Manual.

INTRODUCTION
The SCM is a light weight, manually operated hand tool intended for use with Apex and Magnus
strapping. The tool is easy to load, tension and seal.
Once the strap has been placed around the package, the operator puts both layers of strap into
the tool, lowers the feed wheel, removes any strap slack and tensions the strap. The keyed
sealless joint is then created and the strap is cut free of the supply.
This manual provides the information necessary for the operation of the SCM hand tool and lists
all of the parts in the event maintenance is needed. Therefore, it is valuable and should be saved.
Extra care should be taken in performing maintenance on the SCM since fasteners and other small
components used on this tool are a combination of SAE and metric sizes.

OPERATING INSTRUCTIONS
Wear safety glasses. Stand to one side of the strap while tensioning.
Make sure all bystanders are clear before proceeding.
1.
STRAP PREPARATION.
Encircle the package with strap by passing the
loose end over the top and bringing it back
around. This will result in a top strap and a
bottom strap.
2.
TOP AND BOTTOM STRAP INSERTION. Squeeze
the sealer handle and the feedwheel support
handle together with the right hand. With the left
hand, align the top and bottom straps. Then,
with a sideways motion, insert them into the tool,
making sure both straps are fully seated in and
against the front and back strap guides. Note
that both straps must be placed between the
feed wheel and the clutch plug. Make sure the
lead end of the bottom strap extends about 1" to
1 1/2" (25 - 40mm) beyond the front of the tool.
3.
REMOVING SLACK STRAP. After the straps
have been inserted into the tool, release the
feedwheel support handle. With the left hand,
grasp the top strap and pull back on it to
remove slack strap. Pull it snug around the
package. The feed wheel will rotate as the strap
is being pulled back.

7
4.
APPLYING TENSION. While standing to one side
of the strap line, grasp the tension handle with
the right hand and the sealer handle with the left
hand. Move the tension handle forward and
back between the 11 o'clock and 2 o'clock
positions repeatedly, until the strap is tensioned
around the package.
Never push the tension handle all the way forward past the 11 o'clock position as the
feedwheel will lift and the tensioned strap will release from the tool.
Never squeeze the feedwheel support handle and sealer handle together while
tensioning strap.
5.
SEALING THE STRAPS. After the strap has been tensioned, grasp the sealer handle with the
left hand. Move the sealer handle fully forward while pulling back on the tension handle to
punch completely through both layers of strap.
NOTE: If the sealer handle is not cycled fully forward the strap will not be completely punched
or cut off. If this occurs the tool cannot be removed from the tensioned strap. To remove the
tool cycle the sealer handle completely forward a second time. If the tool still fails to
completely cut or punch the straps, cut the straps and tool from the package. Check the tool
for worn or broken parts. Inspect the strap joint for proper formation of interlocking keys.

OPERATING INSTRUCTIONS, Continued
6.
REMOVING THE TOOL. Hold the cut-off end of
the top strap with the left hand and squeeze the
feedwheel support handle and the sealer handle
together with the right hand. Swing the rear end
of the tool to the right to remove it from the
tensioned tie. The strapping cycle is now
complete. Inspect the strap joint for proper
formation by reviewing Joint Appearance and
Formation below.
STRAP JOINT APPEARANCE & FORMATION
A properly formed joint will appear as shown in the following illustration.
If the joint does not appear as shown, then the operator must proceed as follows:


Make sure that the tool's operating instructions are being followed
before applying
another strap.


Make sure that tension has been applied to the straps before the sealer handle has
been actuated.
Tension is necessary to ensure that the keys fully interlock.
After confirming the above, cut off the strap 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.

ROTATE THE LOCKING PLATE
CLOCKWISE TO LOWER THE CUTTER
FOR THINNER GAUGE STRAPPING.
ROTATE THE LOCKING PLATE
COUNTERCLOCKWISE TO RAISE THE
CUTTER FOR HEAVIER GAUGE
STRAPPING.
ADJUSTMENTS
CUTTER
The cutter may have to be adjusted if the tool has been altered to accept a different width or
thickness of strap or an adjustment may be needed if the cutter has been replaced due to wear or
damage.
Run a cycle with strap of the size to be used. A properly adjusted cutter will sever the top strap
completely but the lower strap will have minimal impression,
at the most.
Excessive scoring of
the lower strap is an indication of over cutting and this is not acceptable.
Lay the tool with the strap loading side down, remove the socket head cap screw (SHCS) that
attaches the locking plate to the base (it is not necessary to remove the locking plate). Insert a 5.0
mm hex wrench into the end of the eccentric shaft. Rotate the shaft clockwise a few degrees for
thinner strap or counterclockwise for heavier strap. There are two mounting holes available for
the locking plate. Align the “nearest” hole in the plate to the mounting hole in the base and
reinstall the socket head cap screw.
FEEDWHEEL AND CLUTCH PLUG
There is no adjustment for feedwheel/clutch plug clearance. The clearance should be .001" to
.010" (0.025 to 0.25mm). The most important issue is that the feedwheel does not interfere with
the clutch plug.
