MVC-80VH/VHW PLATE COMPACTOR — GENERAL INFORMATION
Definition of Plate Compactor
The Mikasa MVC-80VH/VHW 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.
Vibratory Plates
The vibratory plates of the MVC-80VH/VHW 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.
Frequency/Speed
The compactor's vibrating plate has a frequency range between
5600 vpm (vibrations per minute). The travel speed of the
compactor is approximately 72 ft./minute (22 meters/minute).
Engine
The Mikasa MVC-80VH/VHW Plate Compactor is equipped with
a Honda GX160U1SM12 gasoline engine.
Controls
Before starting the MVC-80VH/VHW Plate Compactor identify
and understand the function of the controls and components.

sponding the compression point. Rewind the rope a little from
that point and pull out sharply.

MVC-80VH/VHW PLATE COMPACTOR — OPERATION & PARTS MANUAL — REV. #0 (05/01/06) — PAGE 19
Operation
1. Once the engine has started, move the engine throttle lever
quickly to the
fast position.
2. With the throttle lever in the fast position, the engine speed
should be around 2,300 RPM, therefore engaging the cen-
trifugal clutch.
ALWAYS move the throttle lever
quickly without hesitation,
because increasing the engine
speed slowly causes the clutch
to slip.
5. Firmlygrasp the compactor's handlebar with both hands, the
compactor will begin moving forward.
6. 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.
7. 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:
MVC-80VH/VHW— INITIAL START-UP/OPERATION
6. If the engine has started, slowly return the choke lever
(Figure 11) to the
CLOSED position. If the engine has not
started, repeat steps 1 through 5.
7. Before the compactor is put into operation, run the engine for
3-5 minutes.
8. Check for abnormal engine noises or fuel leaks.
Normal Shutdown
1. Place the throttle lever (Figure 12) in slow position, and
listen for the engine speed to decrease.
2. Place the
Engine ON/OFF switch (Figure 10) in the " OFF "
position.
3. Place the
fuel valve lever (Figure 9) in the " OFF " position.
Emergency Shutdown
1. Move the throttle lever quickly to the slow position, and
place the
Engine ON/OFF switch in the " OFF " position.
Stopping the Engine
NOTE
■ 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.
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.

MVC-80VH/VHW— MAINTENANCE
Inspection and other services should always be carried out
on hard and level ground with the engine shutdown.
Inspection and Maintenance Service Tables.
1. To make sure your plate compactor is always in good
working condition before using, carry out the maintenance
inspection in accordance with Tables 5 through 7.
These inspection intervals are for operation under normal
conditions. Adjust your inspection intervals based on the
number hours plate compactor is in use, and particular
working conditions.
