To ensure maximum efficiency, a preventive inspection schedule should be followed.
The operational schedule of the shaker determines the inspection schedule. A shaker
operating daily should be inspected more frequently than a shaker that is used less
frequently. Tightness of electrical connections and screws should be checked on
regular basis prior to operating the system. A complete preventative maintenance is
recommended after the first 250 hours of operation and each 1000 hours thereafter.
● Clean or suck the dirt inside the power amplifier, shaker and air duct connecting
the blower by a cleaner.
● Insure all the cable connections are not loosened, especially the connection on A+,
A-, F+, and F- on the rear of the power amplifier.
● Check correct grounding.
