TM 5-3895-383-244.Depress vibratory on/off control switch (1) to the ONposition in order to start the vibratory system. Recordthe vibrations per minute (VPM) from the optional gaugeon the steering console. The vibrations per minute maybe read from 133-0963 Vibration Tachometer or the133-9905Frequency Meter. The maximum VPM settingfor high amplitude for the CS-563D and the CP-563Dshould be 1965 ± 50 VPM. The maximum VPM settingfor high amplitude for the CS-583D should be 1800 ± 50VPM.NOTE: Verify the accuracy of the optional gauge on thecontrol panel. Refer to Testing and Adjusting,"Vibratory Tachometer - Adjust".5.Depress the vibratory on/off control to the OFF positionin order to stop the vibratory system.Illustration 59Frequency Adjustment(4) High amplitude adjustment screw. (5) Vibratory pump.6.If the frequency is not correct, adjust high amplitudeadjustment screw (4) on pump (5). Loosen the locknuton the adjustment screw (4). Turn high amplitudeadjustment screw counterclockwise in order to increasemaximum VPM. Turn the adjustment screw clockwisein order to decrease maximum VPM.Low Amplitude1.Move vibratory amplitude control (2) to the LOWAMPLITUDE position.2.Depress vibratory on/off control switch (1) to the ONposition in order to start the vibratory system. Read thevibrations per minute (VPM) from optional VPM gaugeor read the VPM from the 133-0963VibrationTachometer or the 133-9905 Frequency Meter. Themaximum VPM for low amplitude is 1965 ± 50 VPM.Illustration 60Frequency Adjustment(6) Vibratory pump. (7) Low amplitude adjustment screw.3.If the frequency is not correct, adjust low amplitudeadjustment screw (7). Loosen the locknut on theadjustment screw (7). Turn adjustment screwcounterclockwise in order to increase maximum VPM.Turn adjustment screw clockwise in order to decreasemaximum VPM.4.Depress vibratory on/off control switch (1) to the OFFposition in order to stop the vibratory system.Variable FrequencyHigh Amplitude (Minimum Frequency)1.Use the 4C-6500 Digital Thermometer in order to verifythat the hydraulic oil temperature is at least 38C(100F).2.Position the drum on tires.3.Apply the parking brake and place the propel controllever in the STOP position.4.Run the engine at high idle. The engine rpm should be2350 ± 50 rpm.5.Place the vibratory amplitude control (2) in the HIGHAMPLITUDE position.11-55
