------ WARNING! ------

Operate the engine at full rpm for maximum braking, steering and propel control response. Operation below full throttle will adversely affect response.

When climbing a steep grade, the propel control lever must be moved SLOWLY in order to avoid engine stall and possible loss of machine control.


If you are performing an action that requires a significant amount of power, such as climbing a hill, monitor the engine's performance. If too much power is required from the engine, the engine could stall. If the engine begins to stall, decrease the propel speed. When you decrease the propel speed, the engine's load is reduced.

Set the throttle control to the HIGH position. Attain the desired travel speed before you engage the vibratory system. In order to achieve optimum compaction, low range should be used.

Stop the vibration system when you travel over concrete or pavement that is hard.


NOTICE

The bearings in the vibratory reservoir for the weight shaft are lubricated by rotating the drum assembly. Turning the vibratory system on with the machine not propelling may shorten the vibratory bearing life.


Begin the first pass of the compaction along the side of the work. Gradually make subsequent passes toward the center. Overlap the previous pass by 200 mm (8.0 inch) in order to eliminate uncompacted areas.


NOTICE

Before changing the vibratory amplitude selection, the system must be completely stopped.

High Amplitude

In order to increase the height of the drum movement, place the vibratory system in high amplitude.

High amplitude is used in the following situations.

  • The job site requires higher compacting force in order to meet the required density.

  • In order to compact material with a depth of 250 mm (10.0 inch) or more, use high amplitude.

Note: Once you have achieved the desired density of the material, continued operation at high amplitude can crush the aggregate.

Note: Every job site is different due to the various conditions of the soil. Moisture content and the type of material vary from job site to job site. In order to determine the amplitude that is needed, establishing a test location at each job site is recommended.

  1. In order to place the vibratory system in high amplitude, depress the front of vibratory amplitude control (2) downward.

  2. Move the propel lever to the FWD position or the REV position.

  3. Start the vibratory system by pressing vibratory on/off control (1). The control is located on the top of the propel lever.

  4. In order to stop the vibratory system, press vibratory on/off control (1).

  5. Return the propel control to the STOP position.

Low Amplitude

In order to decrease the height of the drum movement, place the vibratory system in low amplitude.

Low amplitude is used in the following situations:

  • When operating the machine in high amplitude and the drum separates from the soil, use low amplitude in order to reach the desired soil density.

  • The thickness of the material is less than 250 mm (10.0 inch).

  • Objects such as sewer systems or water systems may be damaged due to high amplitude.

  1. In order to place the vibratory system in low amplitude, depress the bottom of vibratory amplitude control (2) downward.

  2. Move the propel lever to the FWD position or the REV position.

  3. Start the vibratory system by pressing vibratory on/off control (1). The control is located on the top of the propel lever.

  4. In order to stop the vibratory system, press vibratory on/off control (1).

  5. Return the propel control to the STOP position.

Variable Vibration Control Knob (If Equipped)

Illustration 4g01946808

The variable vibration control knob (3) is used to vary the frequency of the drum vibration. Rotate the knob (3) in a clockwise direction in order to increase the drum vibration. Rotate the knob in a counterclockwise direction in order to reduce the frequency of the drum vibration. The drum vibration can be varied from 1450 to 1915 vibrations per minute (VPM).

Note: Do not operate the machine below 1450 (VPM). Damage to the machine may occur.

Operation of the Variable Vibratory System

  1. Start the machine with the engine in low idle.

  2. Place the throttle control to the HI idle position.

  3. Move the vibratory amplitude control (2) to either the HI or the LOW amplitude setting.

  4. Press downward on the vibratory on/off control (1) that is located on the top of the propel control lever in order to start the vibratory system.

  5. Rotate the variable vibration control knob (3) clockwise. The vibratory system's frequency of vibrations per minute will increase.

  6. Rotate the variable vibration control knob (3) in the counterclockwise direction in order to decrease the frequency of the vibrations per minute.

Shutting Down the Vibratory System

  1. Push down on the vibratory on/off control (1) on the top of the propel control lever in order to stop the vibratory system.

  2. Move the vibratory amplitude control (2) to the OFF position.

    Note: Moving the vibratory amplitude control (2) to the OFF position resets the controller.

  3. If the machine is shut down, switch the throttle control to low idle before the engine is turned OFF.
