MVC-90H PLATE COMPACTOR — GENERAL INFORMATION
Definition of Plate Compactor
The Mikasa MVC-90H is a 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-90H has a heavy-duty steel base plate with closed
design. It is ribbed for extra strength. The tubular steel roll
bar cage protects engine components and provides a lifting
point.
The MVC-90H also has a reversible, shock-mounted handle.
Vibratory Plate
The vibratory plate of the compactor produce 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.
The double-V belt drive assures less downtine and superior
drive characteristics. Unit can still operate if one belt breaks.
WaterTank
The compactor has a built-in water tank which helps provent
damage and adds to long life. Brass water valve eliminates
rust and corrosion problems.
Frequency/Speed
The compactor's vibrating plate has a frequency range
between 5,800 vpm (vibrations per minute). The forward
and reverse travel speed of the compactor is approximately
82 ft./minute (25 meters/minute).
Engine
The Mikasa MVC-90H Plate Compactor is equipped with a
Honda GX160K1QMX2/GX160U1QMX2 air cooled, 4-cycle
gasoline engine. The engine drives an eccentric weight at a
high speed to develop a compaction force.
Controls
Before starting the MVC-90H Plate Compactor identify and
understand the function of the controls and components.

MVC-90H PLATE COMPACTOR — OPERATION
Operation
1. Once the engine has started, move the engine throttle
lever quickly to the FAST position. With the throttle lever
in the fast position, the engine speed should be around
2,300 RPM, which engages the centrifugal clutch.
2. Firmly gasp the compactor's handle bar with both hands
as the compactor begins moving forward.
3. 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.
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.
Operating the Compactor on High Moisture Content Soil
Compactor traveling speed may drop on soils which contain
clay, or other types of soil.Soil with high moisture content can
cause the compaction plate to "stick" to the ground (not lifting
up off the ground very fast or high).
To rectify this problem, consider the following:
 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.
 Remember the compactor does not work as efficiently
on clay or soils that have a high moisture content level.
 If the soil has a high moisture level, dry soil to
appropriate moisture content level or carry out
compaction twice.
Always move the throttle lever
quickly without hesitation.
Increasing the engine speed
slowly causes the clutch to slip
and can damage your clutch.
CAUTION - General Operation Safety
NOTE
Using the Compactor Sprinkler System
The MVC-90H is equipped with a watering system that can
be used to wet the ground during compaction to keep dust
levels down.
To operate the watering system, turn the water cock handle
to open the valve (Figure 18) and start the water flow.With the
compactor at full speed and the water cock fully open, the
water system will provide approximately 20 minutes of
sprinkling.
Figure 18. Water System
Whenever the compactor's vibra-
tion becomes weak or lost during
normal operation regardless of op-
eration hours, check the V-belt
and clutch immediately.
