Frequently Asked Questions
Q: What checks need to be performed before starting the machine?
A: Check the lubrication, voltage, emergency stop button, cutter position, feed guides, etc.
Q: Is it normal for burrs to appear on the cut edges of the sheet metal after cutting?
A: Minor burrs are normal and acceptable; however, severe burrs are typically caused by a dull cutting blade or improper blade clearance.
Q: How should the machine be stored when not in use for an extended period?
A: Disconnect the power, clean the machine, apply anti-rust oil, cover it with a dust cover, and store it in a dry environment.
Q: How many people are required to operate the machine?
A: It requires just one operator plus one person to handle the output; for highly automated models, a single person is sufficient.
Q: How long is the warranty period?
A: The entire machine comes with a 12-month warranty, excluding wear parts.
