Oil Handling

POE oil is very hygroscopic, which means it absorbs
moisture very readily. Therefore, it is important to
properly handle the oil.
POE Oil handling guidelines
• Always use the smallest container size required for the
job requirements.
• Always leave the oil container tightly sealed until time
of use.
• Do not reuse oil that has been opened.
