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.

! 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.

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.

Signode tools and machines are designed and warranted to work together with Signode strapping and seals. Use of non-Signode strap, 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

1. Before using this tool, read its Operation and Safety Instructions contained in this manual.

2. This tool is a double notch type sealer. Each joint must be inspected to make certain it has four (4) good notches. 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. Make certain that the tool's operating instructions are being followed before applying

another strap.

B. Cut the strap off and apply a new strap and seal.

C. An improperly 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 strap and check the tool for worn or broken parts. Repair the tool before applying another strap.

NOTE: NOTCHES MUST BE EQUALLY SPACED ALONG THE ENTIRE LENGTH OF THE SEAL.

FAILURE TO EQUALLY SPACE THE NOTCHES COULD RESULT IN STRAP SEPARATION.

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

FLYING STRAP HAZARD. 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.

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 severe personal injury.

LOADING SEALS

An extension on the seal pad (61) closes the top strap loading slot as a reminder to add seals. Raise the seal pad assembly and insert a stack of seals in the side of the seal magazine. Make sure the seal stack is pushed all the way in. You may load seals at any time without waiting for seals to run out, because you can break a stack and load as many or as few as you wish.

STRAPPING TIE

1. Encircle the package with the strap and insert the bottom strap-end under the rocking gripper. Push it forward until it contacts the gripper stem. Press the gripper trigger to actuate the holding gripper.

2. Insert the top strap under the feedwheel and insert it sideways into the slot of the strap latch. Pull the excess slack from the strap.

3. Loosen the cutter adjustment set screw (9).

4. Remove the two magazine screws (6 and

8) on the left side of the sealer frame.

5. Remove the two socket head cap screws (37) from the bottom of the tensioner frame (39).

6. Pivot the rear of the tensioner frame away from the sealer frame and tilt the top of the magazine away from the sealer mechanism and lift the magazine assembly out.

7. Remove the sealer mechanism from the sealer frame.

3. Be sure the strap guide spring (36) is in its proper position in the tensioner frame. Swing the tensioner frame up against the sealer frame and insert and tighten the two socket head cap screws (37) through the tensioner frame.

4. Insert the magazine screws (6 and 8) through the sealer frame and into the magazine. Snug - do not tighten at this time.

5. Move the sealer handle to the vertical position to bring the sealer mechanism to the full down position. Adjust the cutter adjustment screw (9) and tighten both magazine screws (6 and 8).

6. Insert a stack of seals into the magazine. Operate the sealer mechanism through 3 or 4 cycles to check tightness of the cutter adjustment 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.

The magazine and the sealer mechanisms are now accessible for examination and replacement of worn or broken parts. The sealer mechanism is serviced by removing the cutter blade (75). Clean all parts. Replace jaws and notchers (76, 77 and 78) as required. Note that the outer jaws can be reversed front to back to provide new cutting edges, thus doubling the life of the parts. After the necessary repairs have been made, grease the parts.

To reassemble:

1. Place the sealer handle in a horizontal position and insert the sealer mechanism. The hook on the sealer cam (89) must be placed over the cam roller (3) in the sealer frame.

2. With the sealer mechanism in place, push down lightly on the sealer handle to keep the sealer mechanism in place and insert the magazine assembly by placing the lower portion of the magazine between the sealer mechanism and the sealer frame. Tip the top forward to bring it into proper alignment.

EJECTOR AND EJECTOR LEVER ASSEMBLY

1. Remove the seals from the magazine (65).

2. Remove the Truarc (49) from the left side of the ejector pin (64).

3. Drive out the ejector pin from the tension handle side.

4. Remove the ejector lever spring (55).

5. Hold the gripper lever (60) down and pull out the ejector lever (50).

To disassemble the ejector:

1. Remove the Truarc (53) from the ejector pin (54).

2. Remove the pin (54), ejector (52), and spring (51). Replace the ejector lever and/or the ejector as necessary.

3. Reassemble with the new ejector by following the above steps in reverse order.

Page 9

ROCKING GRIPPER (48)

NOTE: If only the ejector needs to be replaced, it can be removed without removing the ejector lever by following the above three steps.

To reassemble the ejector lever:

1. Insert the ejector (52) into the cutter block (67) slot. Hold the gripper lever (60) down and slide the ejector lever (50) into position.

2. Start the ejector pin (64) through the right side of the ejector lever and the magazine.

3. Insert the ejector lever spring (55).

4. Insert a punch from the tension handle side to hold the spring in alignment.

5. Tap the ejector pin (64) in from the sealer handle side, removing the aligning punch at the same time.

6. Push on the lower part of the ejector lever (50) to align the holes on the left side of the magazine. Finish tapping in the ejector arm pin (64).

7. Replace the Truarc (49).

8. Insert seals in the magazine.

Operate the sealer mechanism through 3 or 4 cycles to determine that the seals feed properly.

Turn the tool on its side. The gear housing should be in the up position. With a pair of Truarc pliers, remove the Truarc (49) from the rocking gripper stem (48).

Push the rocking gripper up and out. Insert a new rocking gripper and reinstall the Truarc.

CUTTER ADJUSTMENT

If the cutter on the tool does not cut properly, loosen the shoulder bolt (6) and cap screw (8), and adjust set screw (9) 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.

MAINTENANCE

Clean and apply proper lubrication to all moving parts on a weekly basis. Clean the feedwheel daily with a wire brush (Signode Part No. 023963). 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.

Next, apply a strap under tension to be sure that all elements of the tool operate properly.

FEEDWHEEL (43)

To change a dirty or worn feedwheel, remove the left-hand threaded nut (47) from the feedwheel shaft (32) and the lock nut (45) from the support shaft (22). With the gear housing (31) in the up position, remove the right-hand washer (25), the side plate (44) and the feedwheel (43). Replace the feedwheel and reassemble the parts in reverse order.
