• Loosen the setscrew on the bottom weight only. If the vibratory amplitude was to little rotate the
bottom weight so that it is in closer alignment (more concentric) with the upper weight. If the
vibratory amplitude was to great rotate the bottom weight such that it is lesser alignment (less
concentric) with the upper weight and re-tighten the setscrew. Maximum vibratory amplitude
occurs when the two weights are exactly concentric with each other. Repeat this process as
required until you obtain a vigorous, yet smooth toroid media and part rotation.
• Reassemble the unit by reversing the disassembly steps described above. Securely tighten all
hardware.
Removing and replacing the bowl
The bowl may be removed to empty, clean, maintenance, or other reasons. When replacing the bowl insure
that the two bosses on the underside of the bowl span one of the rubber isolators on which the bowl rests.
These bosses prevent the bowl from rotating during bowl operation. Insure that the bosses DO NOT rest on
any isolator. Insure that the bowl is held down using the large flat washer and wing nut provided.
Motor life
The motor uses armature brushes that wear with service. Ordinarily the brushes will provide about 1000
hours or more of service life. When the brushes wear to the point that the motor operates intermittently or not
at all replace the brushes. Brush replacement requires removal of the motor from the assembly, withdrawal of
the old brushes (two, one on each side of the motor with flat screw slots to facilitate removal), and
installation of new brushes. Contact Burr King Mfg. for brush replacements.
Tips for getting the best service from your model 150SX or 200SX enhanced performance vibratory
bowl
• Use the proper media to reach the result you expect. Burr King Manufacturing will assist you in selecting
the proper media, compound, and process. Use media that will obtain your desired finish without lodging
inside part cavities. Burr King Manufacturing's media is available in several grades, shapes, and material
types to be best for many part materials. Finishes can be obtained from a light matte to a chrome like
shine dependent on part material type and incoming part finish quality.
• Use the proper fluids (compounds) with your media of choice. Burr King recommends BKS-60 low suds
soap for non-ferrous materials, and AR-60 anti-rust soap for ferrous materials. Typically, these soaps are
mixed at 1 to 3 ounces per 1 gallon of clean water. Note that anti-rust soaps such as AR-60 will not
provide extended rust inhibition. If you require more than a few hours of rust inhibition, you should dip
your parts in a commercially available rust inhibitor solution.
• Maintain your media and equipment in a clean condition. If you use a re-circulating, filtration system
such as the Burr King FilterPAK
®
4000, it will greatly reduce the need to clean your bowl and media.
Without a filtration system, you will need to clean your bowl and media at regular intervals to remove
media sludge, and material fines that will accumulate inside the bowl.
• Do not allow your parts to rest in the bowl for extended periods. Doing so may result in stained,
oxidized, or etched parts.
• If your process uses ceramic or plastic media, clean and dry your parts immediately after withdrawing
them from the vibratory bowl. With dry media such as shell or cob cleaning may not be necessary.
• Establish a process time that allows the media and compounds of choice to process your parts to the
desired finish; control this process time from part load to part load in order to assure consistent load to
load results.
• Change your media when its size is reduced to a point that the media lodges in part cavities, if any. Also
change your media if its shape changes to a point where it will not reach desired surfaces.
• Pre-mix your fluids (compounds) to assure consistent mixture. Too much soap will delay results, too
little soap will reduce finish quality, and limit media life.
• Control the quality of the incoming part condition. Variation in lot to lot incoming part quality may cause
variation in the vibratory process output.
