Before using the HOTO Cordless Manual-Feeding Glue Gun, read the product instructions and check that the tool, cable, blade, bit, nozzle, or accessory is properly attached. Let the tool heat properly, apply a small amount first, and press parts together only when you are happy with the position.
Do a short test before starting the real task. Stop if you notice unusual noise, heat, smell, vibration, slipping, or poor fit. For powered tools, keep hair, loose sleeves, and fingers away from moving parts. For measuring or charging tools, double-check the reading or connection before relying on it.
