At the strap inlet the width of the strap guide should exceed that of the strap by
0.5-1.0mm.
At the strap outlet the width of the strap guide should be set between 12.5-13.0mm
when using 9mm or 12mm wide strap, or at 15.5-16.0mm when using 15mm strap.
Both adjustments are made with the guide located on the top of the table, by
loosening the two Allen screws (inlet) or Philips screws (outlet) and placing a length of
strap in the strap guide to gauge the correct measurement.
Adjustments
Strap width
The strap width adjustment requires a Philips head screwdriver and a 4mm Allen key and is made in two places as
shown below.

The most common settings for the temperature are 3 or 4, but any position can be
selected between 1 and 6.
Optimum temperature will vary depending on the ambient temperature of the
machine location and the quality of the strap.
Gradually increase or decrease the temperature setting until an optimum seal is
obtained, but bear in mind that both too high and to Low temperatures will give
a poor seal.
Daily maintenance
Use high-pressure air to remove dust and debris from the cutter and strap guide
areas indicated in the following illustrations. Remove all plastic residue from inside
the machine.
Maintenance
High reliability and long service life of this machine depend on regular lubrication, cleaning and maintenance.
Lubrication
Only non-resinous SAE 30 lubricant should be used. Care should be taken to avoid spread of lubricant to
components having contact with the strap, such as tension rollers and strap guides.
Weekly maintenance
Thoroughly clean and lubricate the front bar, press bar and rear bar areas shown in crosshatches on the
above illustration.
Monthly maintenance (or every 3,000 strapping cycles)
1. Clean both sides of the heater plate and polish with fine sandpaper if necessary. Ensure the heater plate
is cool before carrying out this maintenance!
2. Check seal head cam rollers for easy movement and ensure seal head returns automatically to home
position under spring tension.
3. Clean all debris away from the tension roller.
Strap tension
The tension adjustment is a knurled steel knob located on the rear of the machine, directly below the strapping
table. Turning the knob clockwise will increase strap tension and anticlockwise will reduce it.
Sealing temperature
The control panel for the sealing temperature is located underneath the hinged stainless steel table top.
To access it, remove the two screws at the front of the table top and lift it towards the back.
