4.
Depress vibratory on/off control switch (1) to the ON
position in order to start the vibratory system. Record
the vibrations per minute (VPM) from the optional gauge
on the steering console. The vibrations per minute may
be read from 133-0963 Vibration Tachometer or the
133-9905 Frequency Meter. The maximum VPM setting
for high amplitude for the CS-563D and the CP-563D
should be 1965 ± 50 VPM. The maximum VPM setting
for high amplitude for the CS-583D should be 1800 ± 50
VPM.
NOTE: Verify the accuracy of the optional gauge on the
control panel. Refer to Testing and Adjusting,
"Vibratory Tachometer - Adjust".
5.
Depress the vibratory on/off control to the OFF position
in order to stop the vibratory system.

Frequency Adjustment
(4) High amplitude adjustment screw. (5) Vibratory pump.
6.
If the frequency is not correct, adjust high amplitude
adjustment screw (4) on pump (5). Loosen the locknut
on the adjustment screw (4). Turn high amplitude
adjustment screw counterclockwise in order to increase
maximum VPM. Turn the adjustment screw clockwise
in order to decrease maximum VPM.
Low Amplitude
1.
Move vibratory amplitude control (2) to the LOW
AMPLITUDE position.
2.
Depress vibratory on/off control switch (1) to the ON
position in order to start the vibratory system. Read the
vibrations per minute (VPM) from optional VPM gauge
or read the VPM from the
133-0963 Vibration
Tachometer or the 133-9905 Frequency Meter. The
maximum VPM for low amplitude is 1965 ± 50 VPM.

Turn adjustment screw clockwise in order to decrease
maximum VPM.
4.
Depress vibratory on/off control switch (1) to the OFF
position in order to stop the vibratory system.
Variable Frequency
High Amplitude (Minimum Frequency)
1.
Use the 4C-6500 Digital Thermometer in order to verify
that the hydraulic oil temperature is at least 38C
(100F).
2.
Position the drum on tires.
3.
Apply the parking brake and place the propel control
lever in the STOP position.
4.
Run the engine at high idle. The engine rpm should be
2350 ± 50 rpm.
5.
Place the vibratory amplitude control (2) in the HIGH
AMPLITUDE position.
