Long-term and frequent contact with oil may lead to skin cancer. Although this is not
certain, it is still recommended to avoid direct contact as much as possible. In case of
contact, wash the skin that has been exposed to oil with soap and water immediately and
thoroughly.
To protect the environment, please properly dispose of the waste oil. We strongly recommend you to:
contain the waste oil with the sealed container and then send it to the local service station or the waste oil
recycling center. Remember: Do not throw oil into the garbage or dump it on the ground or in the ditch.
