You can increase the life of your battery by doing the following:

– Don’t leave your device plugged in once it has finished charging.
– Try to keep your battery at room temperature and avoid leaving it in cold/hot places, like your car, for extended periods.
– Don’t run your battery completely down every time. Keeping your battery charged will increase its life.
– Turn the device off when you’re not using it.

Every cartridge has an expected life span of approximately 4-5 refills. After that point performance of the cartridge may not be as good and replacement of the cartridge is recommended.

Simply slide the front cover that is surrounding the cartridge area, screw in your larger cartridge to Mini Tank, and the slide the front cover back over the cartridge. The front cover is not needed to use the Mini Tank if it does not fit back over.

The EASY FILL oil cartridge makes filling your cartridge very simple. Just unscrew the top of the cartridge and the top along with the entire center pole will be removed. Using a syringe or dropper, fill the cartridge with your product up to or just right below the 0.5ml fill line. Then reassemble the cartridge by screwing the top and center pole piece back onto the cartridge.

Tip: it helps to jiggle the top portion a little when reassembling to make sure no air bubbles are trapped beneath the center pole.
