INSTRUCTIONS FOR PULLING A VACUUM
The following guidelines should be followed when using
BIRO
vacuum tumblers. Due to the nature
of the manufacturing processes by which these drums and lids are made, there are slight differences in the
diameter of the drum opening, and the diameter of the lid. These differences are normal, and have no
impact on the performance of your tumbler.
• Make sure that the lid gasket is sealed properly.
• Center the lid in the opening of the drum.
• Start the vacuum pump.
• Apply pressure in the center of the lid.
