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.
SEAL, LID AND DRUM ASSEMBLY
1. BE SURE SEAL IS PUSHED ON COMPLETELY
2. PUSH LID ON TO DRUM WHILE DRAWING
A VACUUM

thegasketandtopplatewilltinonepositiononly.
To replace the diaphram, remove the socket cap screws from the head of the pump. The diaphram is held in place by
twophillipsheadscrews.Removescrews,retainerplateandthediaphram.Thediaphramwilltinanypositionon
the connecting rod. Replace the plate and the two phillips head screws. Torque to 30 inch-pounds.
CAUTION: Do not raise any burrs or nicks on the heads of these screws. These burrs could cause damage to
the inlet valve.
For replacing the inlet and the outlet valve, remove the slotted machine screw that holds each valve in place. The
stainless steel inlet and outlet valves are interchangeable* Clean them with water. When replacing the outlet valve,
place the new valve in location and note there is a retaining bar near the machine screw hole. The retaining bar holds
the valve in position. When replacing the inlet valve, note that the valve holder is marked with an X in one corner.
This X should be in the lower right hand corner toward the inlet of the air chamber. Replace the head and tighten the
socket head screws, to 90-100 inch-pounds of torque.
WARNING: The motor may be thermally protected and can automatically restart when the overload resets.
Always disconnect power source before servicing. Personal Injury and/or Property Damage could result.
Do not attempt to replace the connecting rod or motor bearings. If after cleaning the unit and/or installing a new
Service Kit, the unit still does not operate properly, contact your representative, the factory, or return the pump to one
of our authorized Service Centers.
IF YOUR PUMP IS EQUIPPED WITH PLASTIC PLUGS IN THE EXHAUST AND/OR INTAKE PORTS,
REMOVE BEFORE STARTING THE UNIT.
OPERATING AND MAINTENANCE INSTRUCTIONS.
Do not at any time lubricate any of the parts with oil, grease, or petroleum products nor clean with acids, caustics or
chlorinated solvents. Be very careful to keep the diaphram from contacting any petroleum product or hydro carbons. It
can affect the service life of the pump.
