GENERAL DESCRIPTION
F. CONTROL PENDANT
The vibrator is operated by a hand-held control pendant. The control pendant has three,
two-way switches (one with a light) and one push button. One switch (SLOW-FAST) raises
and lowers the diesel engine speed. The second switch (REVERSE-FORWARD) starts
and stops the vibrator. The other switch (OPEN-CLOSE) operates the hydraulic clamp.
The light indicates that adequate clamping pressure exists for vibration to begin. The (red
mushroom) push button (EMERGENCY STOP) shuts down the diesel engine instantly, in
the event of an emergency. Note: Controls are duplicated on the control panel in case the
pendant is damaged. (See pg. III-5, Section E-e)
