•  Blow or brush away plastic residues, dust and strap debris from the machine – especially around:

• The tensioning and sealing unit

• The strap track

• Photo sensors and micro switches

• Check that the strap feeds correctly without friction or damage.

• Verify that the seal is strong (no loose joints). Use the separate inspection form.

Recommended:

• Empty the strap magazine to prevent the strap from taking shape and causing feeding problems during startup. The strap should be rewound onto the coil.

• Cover the machine during factory cleaning.
(Protective machine covers are available for purchase.)

• Ensure that boxes are positioned fully against the stop wall during sealing.
Any gap here may result in loose straps.

• Clean the sealing element.

• Check the strapping function and adjust if necessary.

• Test all machine functions in manual mode.

• Inspect the strap track to ensure the strap path is free from deformation.

• Check the adjustment of moving parts according to the machine manual:

• Tensioning mechanism

• Lifting / lowering arms

• Gripper / knife arms

• Inspect drive belts, rollers and springs for wear.

• Check electrical connections for loose contacts.

• Verify the temperature of the sealing element and adjust if the seal is too weak or overheated.

• Perform a complete cleaning, including disassembly of the strap track if necessary.

• Inspect knives / cutting mechanism and replace if worn.

• Check sensors and switches.

• Adjust BR1, BR2, BR3 and CL2. Verify correct function and inspect the tensioning mechanism and associated components.

• Check the cycle switches LS1 and LS2, as well as the machine home position.

Component Replacement Interval (Approx.)

Sealing element / heating knife 6–12 months

Knife / cutter 6–12 months

Springs and belts 12–24 months

Sensors / photo cells When faulty
