GENERAL SAFETY
Connect/start
Storage
If the vibration intensity drops, check that the
filters are not clogged or that hoses are not
kinked.
To properly store unit after use, hang the
vibrator with the head up and set the handle
(variable control assembly) in the open position
to permit the discharge of possible impurities,
contaminants and water.
Placement and consolidation
The force exerted by an internal concrete vibra-
tor is controlled by the weight and the speed
at which the eccentric rotates. The centrifugal
force exerted can be arrived at by various com-
binations of weight (size of eccentric weight)
and the speed at which the weight rotates. For
years the most favorable working speed for a
vibrator was considered to be around 10,200
RPM (VPM) and consequently this figure is used
in many vibrator comparisons. More recently,
the optimum speed for compaction has been
accepted as being between 7500 and 9000
RPM.
