Massager typically generate vibration and pressure, which can promote muscle relaxation and blood circulation. However, if you feel pain or discomfort, it may be due to using the massager at a high intensity or applying excessive pressure in sensitive areas. Lower the vibration intensity or use appropriate attachments and avoid using the massager on joints, bones, or injured areas.

The massager can be used on most muscle groups to promote muscle relaxation and recovery. Common areas of use include thighs, calves, back, buttocks, arms, and shoulders. However, avoid using the massage gun on joints, bones, or any injured areas.

Some noise during the operation of a massager is normal. However, if you find the noise unusually loud or accompanied by abnormal sounds, it may indicate an issue with the internal components of the massage gun. It is recommended to stop using it and contact us for inspection and repair.

If your massager has a short battery life and needs frequent charging, there could be several possible reasons. First, ensure that your massager is fully charged and use the appropriate charger. Secondly, prolonged high-intensity use of the massager can consume more power, which may result in a shorter battery life. If the problem persists, you may need to replace the battery or contact us for further support.

Regular cleaning and maintenance are necessary to keep the massager in good working condition. First, make sure to turn off the massager and unplug it before cleaning. Use a damp cloth or tissue to gently wipe the surface of the massager and attachments. Avoid spraying water directly onto the massager. Additionally, periodically check and replace the massager attachments or components as recommended by arboleaf to ensure its proper functioning.
