Before using the HOTO Air Pump Pro, read the product instructions and check that the tool, cable, blade, bit, nozzle, or accessory is properly attached. Select the correct nozzle, set the pressure carefully if the model supports presets, and check the item pressure before and after inflation.
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.
