The engine speed must exceed 1,800 rpm for vibration compaction.
• The optimum vibration compaction speed is 2~7km/h (1.2~4.5mile/h). However, select an
appropriate speed according to the actual situation of the site.
IMPORTANT
• Do not operate the vibrator on a hard area such as cement concrete pavement
surface or the ground covered by thick steel sheets.
• Shut off the vibrator immediately when the machine has been caught in the mud
during vibratory operation.

2500 position : Vibration can be set at 2500 vpm in the
low or high amplitude position.
3000 position : Vibration can be set at 3000 vpm in the
low or high amplitude position.
4000 position : Vibration can be set at 4000 vpm in the
low amplitude position ONLY.
