Optional propel control lever
Press vibratory control switch (27) on the propel control lever. The vibratory control switch must be held in the ON position for at least 2 seconds for the vibratory system to activate.
Watch pressure on Tool (A) in port "Ma" (12). 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 (27) to shut off the vibratory system.
Place the drums in the high frequency/low amplitude mode.
Press vibratory control switch (27) on the propel control lever. The vibratory control switch must be held in the ON position for at least 2 seconds for the vibratory system to activate.
Watch the pressure on Tool (A) in port "Mb" (13). 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 (27) to shut off the vibratory system.
Place the engine in ECO mode or in low idle.
Move parking brake switch (2) to the ON position.
Move engine start switch (8) to the OFF position.
If the pressure at port "Ma" (12) and the pressure at port "Mb" (13) are within the specified range. Go to Step 43. If the pressure at port "Ma" and/or the pressure at port "Mb" are outside the specified range, adjust the appropriate valve with the following procedure.
