NOTE: When inserting the steel rollers onto the roller bottles we recommend youdo notpush them down with force on the steel ball. If you apply excessive pressure onto the steel roller it will push down the steel ball and stretch out the plastic housing around the ball. Causing oil to come out faster and/or the metal ball to fall out.
Please insert using a tool or push down along the plastic sides,notthe steel ball itself. Pushing excessively on the steel roller ball can cause the housing around the ball to stretch.
