8.)TROUBLESHOOTING
PROBLEM
REMEDY
The tension of strap is insufficient
Check: air pressure value (min.6 bar), if the filter / lubricator and/or the pneumatic motor is
damaged or dirty (contact the after sale service), the power adjusting screw on the pneumatic
motor,
the pneumatic circuit, tension button, connections, pipes, valve (contact the after sale service)
The feed wheel slips and mills on strap
Check if the feed wheel and grippers are dirty or damaged, check the gap between feed wheel and
grippers (around 0,2mm– 0.008”). Adjust the motor power—too much tension force.
Check if the strap qualities are right for the strapping tool and application
The strap is breaking during tension
Adjust the motor power—too much tension force. Check if the strap qualities are right for the
strapping tool and application. Check for sharp edges on package.
The tensioned strap is sideways; the seal isn’t in the middle of strap width
Adjust the motor power—too much tension force. Check if the strap qualities are right for the
strapping tool and application. Check that the strap guides are set for the proper width and are
aligned right.
The lower strap isn’t locked between the grippers and feed wheel so the tool goes forward
during the tension
Check the gap between feed wheel and grippers (around 0,2mm– 0.008”). Check if the locking
strap plates are dirty or damaged. Adjust the motor power for quality of strap
Top strap is dragging on lower strap
Check the gap between feed wheel and grippers (around 0,2mm– 0.008”)- try to increase the gap.
Check if the strap qualities are right for the strapping tool and application.
