Why is the cut & hold not catching plastic film on my McHale Stretch Wrapping Systems?
If the cut and hold mechanism on your McHale Stretch Wrapping Systems isn't catching the plastic film, first check its position. If the table isn't stopping in the correct tip off position, inspect and adjust the magnets as needed.
Why is the plastic not stretching on my McHale Stretch Wrapping Systems?
If the plastic isn't stretching on your McHale Stretch Wrapping Systems, it could be due to a buildup of tack/glue on the dispenser rollers. Clean them off with kerosene. Alternatively, the torsion spring on the dispenser might be weak, in which case you should replace it.
Why is the table stopping in the wrong position on my electronic McHale Stretch Wrapping Systems?
If the table on your electronic McHale Stretch Wrapping Systems is stopping in the wrong position, reset the magnets. Ensure you start with the cut & hold at the rear of the machine. Adjust the slow down setting in the control box. Check the electrical connections for the slow speed valve. Clean the dirt in slow speed cartridge. Ensure that you set table rotation to 10 rpm.
Why is the control box not counting on my McHale 991B Stretch Wrapping Systems?
If the control box on your McHale Stretch Wrapping Systems isn't counting, the sensor might be damaged, or the magnet broken. Locate and replace them. Adjust the sensor approximately 10-15 mm from the magnet. If these steps do not solve the issue, the control box may be faulty and require replacement.
What to do if the cut & hold is not opening on my McHale 991B?
If the cut and hold mechanism on your McHale Stretch Wrapping Systems is not opening, the pressure on the accumulator might be low. Prime the accumulator to resolve this issue.
What to do if the cut & hold is not closing on my McHale 991B?
If the cut and hold mechanism on your McHale Stretch Wrapping Systems is not closing, the pressure on the accumulator might be too high. Release pressure from the accumulator.
How to troubleshoot a lift arm that is not operating on a McHale 991 BJS Stretch Wrapping Systems?
If the lift arm on your McHale 991 BJS Stretch Wrapping Systems isn't operating, check and correct any faulty power supply or electrical connections. If the diverter spool is sticking due to grit, check the oil for cleanliness. Also, verify that the joystick switch is operating correctly and correct if necessary.
Why is the plastic getting caught around the cut & hold on my electronic McHale 991B?
If the plastic is getting caught around the cut & hold on your electronic McHale Stretch Wrapping Systems, the table down magnet might be set too high. Reset the table down magnet.
Why are the cut & hold and tip-up cycles very slow on my McHale Stretch Wrapping Systems?
If the cut & hold and tip-up cycles are very slow on your McHale Stretch Wrapping Systems, ensure the tractor has 150 bar pressure. If it is an electronic machine, replace the faulty pressure switch. Ensure that the relief valve is set to 150 bar pressure.
Why is the dump valve on the control valve leaking on my electronic McHale 991B Stretch Wrapping Systems?
If the dump valve on the control valve is leaking in your electronic McHale Stretch Wrapping Systems, ensure a free flow return is fitted. Also, verify that the return hose is connected.
