MVC-40G — GENERAL INFORMATION
Definition of Plate Compactor
The Mikasa MVC-40G is a one direction (forward) walk behind,
plate compactor designed for the compaction of sand, mixed
soils and asphalt.This plate compactor is a powerful compacting
tool capable of applying a tremendous force in consecutive high
frequency vibrations to a soil surface. Its applications include
compacting for road, embankments and reservoirs as well as
backfilling for gas pipelines, water pipelines and cable installation
work.
The MVC-40G is small and lightweight. It can be easily handled
by one person in confined areas. It has an accessible front-
mounted vibrator assembly. The sealed belt cover keeps dirt
and rocks away from the belt.
Vibratory Plate
The vibratory plate of the compactor produces low amplitude
high frequency vibrations, designed to compact granular soils
and asphalt.
The resulting vibrations cause forward motion.The engine and
handle are vibration isolated from the vibrating plate.
Frequency/Speed
The compactor's vibrating plate has a frequency of 6,200 vpm
(vibrations per minute). The travel speed of the compactor is
approximately 82 ft./minute (25 meters/minute).
Engine
The MQ Mikasa MVC-40G Plate Compactor is equipped with a
air-cooled, 4-stroke ROBIN EH09-2D gasoline engine. When
adding fuel, always use unleaded gasoline.
Controls
Before starting the MVC-40G Plate Compactor identify and
understand the function of the controls and components as
indicated Figure 3.

compactor will begin moving forward.
4. Slowly walk behind the compactor and be on the lookout for
any large objects or foreign matter that might cause damage
to the compactor or bodily injury.
5. Compactor traveling speed may drop on soils which contain
clay, however there may be cases where traveling speed
drops because the compaction plate does not leave the
ground surface easily due to the composition of the soil.To
rectify this problem do the following:
z Check the bottom plate to see if clay or
equivalent material has been lodged in the plate
mechanism. If so, wash with water and remove.
z Remember the compactor does not work as
efficiently on clay or soils that have a high
moisture content level.
z If the soil has a high moisture level, dry soil to
appropriate moisture content level or carry out
compaction twice.
NOTE
Make sure to follow all safety rules referenced in the safety
section of this manual before operating compactor. Keep work
area clear of debris and other objects that could cause
damage to the compactor or bodily injury.
