GENERAL INFORMATION
PRODUCT DESCRIPTION
The Mikasa MVH150VD2 is a walk-behind, reversible
plate compactor designed for the compaction of sand and
clay. 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 soil compacting for road, embankments and
reservoirs as well as backfi lling for gas pipelines, water
pipelines and cable installation work.
ECCENTRIC WEIGHTS
A set of rotating eccentric weights within the vibrator
case produces low amplitude high frequency vibrations,
designed to compact granular soil. The rotation of the
weights are controlled hydraulically through a lever on the
control handle. Changing the position of the lever allows
smooth transition between forward and reverse travel.
The resulting vibrations cause forward motion. The engine
and handle are vibration-isolated from the vibrating plate.
The heavier the plate, the more compaction force it
generates.
ANTI-VIBRATION HANDLE SYSTEM (AVT)
This compactor is equipped with advanced anti-vibration
handle design that reduces vibration to the operator by up
to 50% compared to other plate compactors.
FREQUENCY/SPEED
The compactor's vibrating plate has a frequency of 5,400
vpm (vibrations per minute). The forward and reverse travel
speed of the compactor is approximately 82 feet/minute
(25 meters/minute).
ENGINE
The plate compactor is equipped with a Yanmar
L48V6AF3R4AAW4 air-cooled, 4-cycle, diesel engine.

hands, the compactor will begin moving forward.
Slowly walk behind the compactor and be on the lookout 5.
for any large objects or foreign matter that might cause
damage to the compactor or bodily injury.
Compactor traveling speed may drop on soils which 6.
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:
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.
NORMAL SHUTDOWN PROCEDURE
Place the speed control lever in the IDLE position. Allow 1.
the engine to cool down for 2 to 3 minutes.
Next, place the speed control lever in the STOP position 2.
(Figure 17) to stop the engine.

Remember the compactor does not work as effi ciently •
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.
NOTICE
Whenever the compactor's vibration becomes weak or
lost during normal operation, regardless of operation
