FAQ:

• Why does stretch film easily break when wrapping?

  There are three common reasons: (1) the tension of the stretch film is set too high; (2) the film is thin, brittle, or damaged; (3) the film carriage or roller is stuck, causing uneven force. The solutions are to appropriately reduce the tension, use high-quality stretch film, and clean the guide rollers.

• What should I do if the goods in the package are loose?

  (1) Increase the stretch ratio of the film to achieve tighter packaging; (2) Slow down the hoist speed of the rack to improve film overlap; (3) Check if the pre-stretch mechanism is working properly without slipping; (4) Wrap 2–3 more layers at the bottom of the goods to better secure them.

• Why does the turntable not rotate or run slowly after starting?

  First, check whether the emergency stop button has been reset and whether the inverter parameters have been incorrectly adjusted. Then check if the chain or belt is loose or slipping, and whether the motor is abnormal. Low-speed force is usually caused by a low inverter current setting or the brake not being released; readjust the parameters to correct it.

• How to deal with increased noise after long-term use?

  The main reasons are insufficient lubrication or loose parts. (1) Lubricate the turntable bearings, chains, and gears; (2) Tighten loose screws, film holders, and covers; (3) Clean debris under the turntable to avoid friction noise. Regular maintenance can greatly reduce noise.
