Answer: The size of the air hose should be correct and suitable for the system pressure of the compressed air. Do not use a hose that is scratched, damaged or easily deformed. The model and size of the connectors and fasteners at the end of the hose must be correct; when discharging compressed air, the open end must be firmly grasped, otherwise the hose may injure people due to waving; do not use compressed air directly on people, be very careful when using compressed air to clean equipment, and wear goggles.
