INSTALLATION

Remove the machine from the crate, place it in its proper position, and secure it in place with the caster locks.
The operation may begin once strap of the proper size is loaded and the power cord is plugged into an appropriate electrical outlet.

OPERATING INSTRUCTIONS

Control panel (Fig. 1)

Power button

Press the power button to turn on the unit. The button glows when the unit is in operation.

Press the power button once more to cut off the power supply to the unit.

Strap feed length timer

Metered lengths of strap can be adjusted to automatically feed in a range from 25 mm to approximately 7620 mm.

Reset button

When pushed, the electromagnetic clutch is energized and the strapping head turns one complete revolution, stopping in the home position.

Feed length button

When pushed, an additional strap is fed out into the strap channel. Strap feeding will continue as long as the button is pushed.

Loading strap into the unit (Fig. 2-3)

Withdraw the dispenser assembly (Fig. 2). Place the assembly as shown.

Push down on the lock and turn to disengage from the roll pin that protrudes from the shaft.
Remove the lock and lift the right flange from the dispenser shaft.
Place a coil of strap on the left flange, allowing the shaft to poke through the plastic wrap. (Fig. 3)

Replace the right flange and reinstall the lock.
At this time the securing straps can be removed from the coil of the strap.
Place the dispenser assembly back into the rear end of the unit. Make sure the assembly is placed in properly. The lock should be positioned to the right.

When installed, close the rear panel door.

Cooling time adjustment

Attention: Before making any adjustments to cooling time, turn off the unit.

Threading strap through the machine (Fig. 3)

The threading procedure involves routing the strap from the dispenser and up through the strapping head. Refer to figure 3 and proceed as follows:

Open the right-hand door and pull about 1 meter of strap from the coil.
Thread the strap through the looper (B), pass it under the roller (C), and allow it to exit the cabinet. Close the right-hand door.

Pull up on the strap, then insert the lead end between the guide and roller (D).
Continue to push the strap through the head until it can be seen at point E.

Strapping cycle

The unit is now ready to strap a package.

Proceed as follows:

Push the power button to the “ON” position and allow the hot knife 5 seconds to reach operating temperature.
Place a package on the tabletop, directly above the sealing head. Allow the package to contact the two package stops.

Grasp the strap on the left side of the package, bring it over the package, and insert the lead end into the strap guide on the right side of the package.
- As the lead-end of the strap closes LS1, the strap will be tensioned, welded, and then released, all automatically.
- Caution: Be sure to keep fingers from beneath the strap.

Remove the strapped package and note the length of the strap fed out for the next cycle. Adjust the timer as needed.
Note the condition of the weld and the tension of the tie on the package. If the condition of the weld or the level of tension is unsatisfactory, adjust the hot knife temperature or the tension level as needed.

Operating adjustments

Adjusting tension

If tension adjustment is required, proceed as follows.

Loosen the locking knob at the righthand end of the unit.

Turn the knurled knob, located at the rear of the unit, clockwise to increase tension, counterclockwise to decrease tension.
When set to the desired tension level, tighten the locking knob.

Adjusting hot knife temperature

If the weld appears to be only minimal, it may be that the temperature is improperly set. Make all corrections, in small increments, according to the following conditions.
Raising hot knife temperature: If the weld appears to have insufficient heating, turn the hot knife rheostat (item 19 on the PC board), in a clockwise direction.
Lowering hot knife temperature: If the condition of the weld appears to have been overheated, turn the rheostat counterclockwise.

Replacing strap guides (Fig. 4-6)
Each set of strap guides consists of an exit (Fig. 4) and a re-entry guide (Fig. 5).
Figure 6 shows the correct location of each guide.

Be sure not to inter-mix the sets as feeding reliability will be affected.
Note: When installing the guides, be sure not to over-tighten the mounting screws.

SERVICE ADJUSTMENTS AND CLEARANCES

Anvil (Fig. 7)

To ensure that the anvil operates smoothly, a minimum clearance between the anvil and the left and right guides must be maintained.

To adjust, proceed as follows:

Make sure the right-hand guide is securely mounted.

Loosen the two left-hand guide mounting screws.
Insert a shim, .050mm thick, 3mm wide, and 130mm long between the shoulder of the anvil and the left guide.
Push the left guide against the anvil and tighten the left guide mounting screws.

Remove the shim and check to make sure the anvil moves smoothly.

Switch cam (Fig. 8)

The switch cam is a two level cam. The inner cam actuates LS4 and LS5. The outer cam actuates LS3. To make sure the cams are set properly, proceed as follows.

Make sure the machine is in the neutral or home position.
If the micro-switches need adjusting, loosen the mounting screws and set LS4 and LS5 as seen in Figure 8. When properly set, tighten the mounting screws.

LS3 (Fig. 9)

Position LS3 as shown in figure 9. When set, tighten the mounting screws.

Welding clamp and end gripper (Fig. 10)

To adjust the clearance between the welding clamp and the end gripper, proceed as follows.

Remove the anvil.
Loosen the two socket head cap screws that secure the “L” shaped adjustment bracket to the casting.
Push the block left or right to adjust the clearance. The clearance should not exceed 0.02mm.

When set, securely tighten the two mounting screws.
- Note: If the cutting surface of the welding clamp has become dull, the welding clamp can be turned 180 degrees, thus doubling the life of the part.

Tension lever (Fig. 11)

Before making any adjustments to the tension lever, check to see if the tension lever is level. To check and adjust if need be, proceed as follows:

Manually turn the rotor of the electromagnetic clutch until the key, seen at the end of the camshaft, is positioned as shown in Figure 11.
Make sure the tension lever bearing is in contact with the surface of the cam.

If there is no clearance at points A, B, and C, then the tension lever is considered to be level.
If there is clearance at any point, loosen the locknuts (1) and (2) and adjust all clearance out at points A, B, and C.
When set, tighten the locknuts.

Feed and tension rollers (Fig. 12)

When the machine is in the neutral position, the feed and tension rollers should not come into contact with the strap. The clearance between the rollers should be 1.0 mm. To adjust the feed rollers away from the strap proceed as follows.

Loosen the locknuts and turn all 4 nuts counterclockwise. This will raise the angle plate, pivoting the feed rollers upward. Make all adjustments in very small increments. When set, insert a 0.5mm shim between the angle plate and the locknut B and tighten locknut A against locknut B.

Remove the shim and press down on the angle plate. Tighten the locknuts, C and D.
- Note: To adjust the tension rollers away from the strap, follow the above steps in reverse order.

MAINTENANCE

Before servicing the unit

Warning:

Wear safety glasses with side shields that conform to ANSI standard Z87.1. Failure to wear safety glasses could result in severe personal injury or blindness.
Only trained personnel should service the unit.

Unless specified, shut off and disconnect all electrical power.
Follow all service instructions.
Make sure the hot knife is cool before servicing.

Use the correct tools.
Never adjust, repair, or oil moving parts.

General

Periodic checks of all drive belts for replacement should be made to prevent worn-out or stretched belts which will affect tensioning.

Lubrication (Fig. 12)

Make sure the unit is clean before applying lubricants to the points shown in the figure below. Note: Use a brush or compressed air to remove debris.

Tension trip arm assembly sleeves

Apply a few drops of light machine oil to the edge of the sleeve so that the oil can penetrate to the shoulder of the screw.

Guide plates, welding clamp, end gripper, and holding gripper (Fig. 12)

Apply light machine oil to these parts at the points indicated in Figure 12.

Gear reducer

Replace the oil in the gear reducer once a year in the following manner.

Remove the oil filler plug at the top of the reducer.
Remove the lower plug and allow the oil to drain from the gearing.
Reinstall the lower plug and fill it with gear oil.
Reinstall the upper plug.

The following parts should never be lubricated:

Electromagnetic clutch
Roller assemblies
Belts and pulleys
Clutch disc
