7.2 Periodic and Preventive Maintenance
The following preventive measures will help ensure long term operation of your Branson
2000 Series Actuators.
7.2.1 Periodically Clean the Equipment
Periodically disconnect the unit from power, remove the cover and vacuum out any
accumulated dust and debris. Remove material adhering to the circuit boards, cooling
intake vents and exhaust ports. Periodically disconnect the airline from the air supply,
open the air filter and clean the element and bowl with mild soap and water. External
covers may be cleaned with a damp sponge or cloth using a solution. Do not allow
cleaning solution to enter the unit. Exposed steel surfaces, such as handles, and hardware
may require a very light film of oil, such as WD-40, to prevent rust in areas of high
humidity.
7.2.2 Recondition the Stack (converter, booster, and horn)
Stack components function with greatest efficiency when the mating interface surfaces
are in proper condition. Stacks used with silicone grease, as with all 40 kHz products,
should be periodically reconditioned to eliminate fretting corrosion. We recommend that a
stack using silicone grease be inspected every two weeks for corrosion. the inspection
interval can then be adjusted longer or shorter as required, when experience is gained for
specific stacks. See the Branson instruction manual for correct stack interface
reconditioning procedures.
To recondition the interfaces:
1. Remove the stack from the Actuator
2. Disassemble the converter, booster, and horn stack. Observe the following rules: In the event
that you must disassemble a Stack, always use the correct spanner wrench and a suitable soft-
faced vise to remove a horn or booster, and reverse the procedures described earlier in this
Section
NOTICE
The operating efficiency of the equipment will be greatly affected if
the mating interfaces of the converter, booster, and horn are not flat,
make poor contact with each other or become corroded. A poor
contact condition wastes power and makes tuning difficult. It may
also affect the noise level and damage the converter.
CAUTION General Warning
NEVER attempt to remove a horn or booster by holding the converter
housing or booster clamp in a vise.
