OPERATION
these materials in most soil conditions, except solid rock
or soil with a very high clay content.
The compactor is placed on the object to be driven using
the front one-third (that portion of the baseplate furthest
from the operator) of the baseplate. This position is critical
to proper delivery of the compactor's vibratory force into
the object. The front portion of the compactor will impart
an impact or "slap" that will drive the material into the soil.
The center portion of the compactor will "rock" on the ma-
terial and provide very little impact force.
Apply down pressure evenly, but do not compress the
shock mounts fully. Too much down pressure will make
the compactor difficult to control on top of the driven ob-
ject, and the impact required will be damped out.
WARNING
SERIOUS INJURY OR DEATH COULD RESULT FROM
ATTEMPTING to support the driven material.
PERSONNEL WHO ATTEMPT TO support the driven
material CAN BE STRUCK OR CRUSHED.
Do not ATTEMPT to support the driven material.
One note of caution; the forces generated and the meth-
ods used while driving with a vibratory device preclude
the calculation of "bearing loads" for a piling or sheet of
material. DO NOT USE THE COMPACTOR IN APPLICA-
TIONS WHERE A BEARING LOAD IS SPECIFIED.
