GENERAL INFORMATION
1. Stop the vibrator.
2. Allow the hydraulic power unit to run for five
minutes at 1200 RPM
3.
Reduce speed to low idle for approximately 30
second.
4. Stop the engine by pressing the engine start/
stop button
Caution: If the hydraulic power unit engine
is shut down while the vibrator is clamped
to a pile, the clamp check valve will keep the
vibrator clamped to the pile. However, system
leakage could result in a loss of clamp pressure
over time. It is NOT recommended to leave the
vibrator clamped to a pile when the power unit
is not running.
Shut Down Procedure
In order to provide maximum flexibility in achieving
optimum pile penetration and extraction rates, the
frequency of the vibratory driver is adjustable.
The frequency can be varied from 900-1850
vibrations per minute by changing the engine
speed. Engine speed is controlled with the governor
on the main hydraulic control panel display, or on
the remote control pendant.
