Press vibratory control switch (23) on the propel lever. The vibratory control switch must be held in the ON position for at least 2 seconds for the vibratory system to actuate.
Watch pressure on Tool (A) in Port "Ma" (11). An initial pressure reading will register on the gauge for a brief period, and then the pressure reduces to operating pressure. Record the initial pressure reading as the main relief pressure. The main relief pressure should be 38000 2000 kPa (5500 290 psi).Note: The force that is needed to overcome the inertia of the weights causes the pressure in the vibration system to momentarily reach the relief valve setting. This force should be the initial pressure reading.
Use vibratory control switch (23) to stop the vibratory system.
Use vibratory frequency switch (13) in order to place the drums in the high frequency/low amplitude mode.Note: Two things indicate when the vibratory system is in the high frequency/low amplitude mode. First, "Vibe Frequency Mode High" will appear on the display. Second, two of the LEDs next to vibratory frequency switch (13) will be illuminated.
Press vibratory control switch (23) on the propel lever. The vibratory control switch must be held in the ON position for at least 2 seconds for the vibratory system to actuate.
Watch the pressure on Tool (A) in Port "Mb" (11). An initial pressure reading will register on the gauge for a brief period, and then the pressure reduces to operating pressure. Record the initial pressure reading as the main relief pressure. The main relief pressure should be 38000 2000 kPa (5500 290 psi).Note: The force that is needed to overcome the inertia of the weights causes the pressure in the vibration system to momentarily reach the relief valve setting. This force should be the initial pressure reading.
Use vibratory control switch (23) to stop the vibratory system.
Use throttle control switch (3) in order to operate the engine in ECO mode or in low idle.Note: Two things indicate when the engine is in ECO mode. First, "ECO" will appear on the display. Second, the second LED next to throttle control switch (3) will be illuminated. Two things indicate when the engine is at low idle. First, "Low Idle" will appear on the display. Second, the first LED next to the throttle control switch will be illuminated.
Move parking brake switch (2) to the ON position.
Move engine start switch (4) to the OFF position.
If the pressure at Port "Ma" (10) and the pressure at Port "Mb" (11) are within the specified range, Go to Step 42. If the pressure at Port
