We often get questions from our clients that come in to our service department. Here is a common Q & AQ. When troubleshooting, should I return to the factory settings? A. Yes. Every time. When our service technician has completed commissioning your system, you will be sent a record of the machine settings that provided for the optimum conveying conditions. Return to these settings. If you cannot locate the factory settings, please call us at 1.800.433.2213 (ext. 120) and ask for Mike DeLand. Or email him at: firstname.lastname@example.org We have these on file. If the system is still not functioning correctly, we will be able to assist you with your needs. The problem could be a variety of causes, for instance, a faulty component, a change in the material conditions or air supply, or other minor issue. The advice you receive over the phone is free, so please do not hesitate to give us a call.
