| NOTICE |
|---|
To avoid damage to the vibratory system during testing, always perform the testing with the vibratory drum on top of tires or on loose dirt. Tires will simulate a non-compacted soil condition. Never operate the vibratory system when the machine is on concrete. |
| NOTICE |
|---|
If a testing time longer than three (3) minutes is required, rotate the drum periodically in order to lubricate the eccentric weight shaft bearings. |

Control Console (1) Vibratory on/off control. (2) Vibratory amplitude control. | |
Note: The hydraulic oil temperature should be at least 38°C (100°F).
- Make sure that the parking brake is applied. Ensure that the propel control lever is in the STOP position.
- Move the vibratory amplitude control (2) to the HIGH AMPLITUDE position.
- Start the engine. Run the engine at high idle. Engine speed should be 2350 ± 50 rpm.
- Depress the vibratory on/off control (1) on the control console to the ON position. Read the vibrations per minute (VPM) from optional VPM gauge (3).

Steering Console (3) Vibratory tachometer. | |
- Read the VPM from 133-0963 Drum Vibration Tachometer (4) or the 133-9905 Frequency Meter. Compare these values with the reading from the optional VPM gauge (3) .

End of Drum (4) Drum vibration tachometer. | |
- VPM gauge (3) must be calibrated if the values are not equal.
- Set large dial (5) on 8.

(5) Dial. (6) Small calibration screw. | |
- Use small calibration screw (6) in order to calibrate the gauge. Use a 2.0 mm (5/64 inch) allen wrench in order to adjust the small calibration screw.
Note: If the reading from VPM gauge (3) is significantly different from the reading for 133-0963 Drum Vibration Tachometer (4) or the 133-9905 Frequency Meter, the magnetic sensor output should be verified before tachometer (3) is calibrated.
