GENERAL INFORMATION
DEFINITION OF PLATE COMPACTOR
The Mikasa MVH508DZ is a reversible plate compactor
designed for efficient compaction of sand, gravel and
cohesive soils. 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 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.
FREQUENCY/SPEED
The compactor's vibrating plate produces a vibration
frequency of 4,150 VPM (vibrations per minute).
The travel speed of the compactor is approximately
82 ft/minute (25 meters/minute).
ENGINE
This plate compactor are equipped with a Hatz 1D81S
air cooled, 4-cycle diesel engine. The engine drives an
eccentric weight at a high speed to develop a compaction
force.
CONTROLS
Before starting the plate compactor identify and understand
the function of all the controls and components.

CAUTION
ALWAYS follow all safety rules in the safety
section of this manual before operating
compactor. Keep work area clear of debris
and other objects that could cause bodily
injury or damage to the compactor.
1. Once the engine has started, move the engine throttle
lever quickly to the operation position (Figure 16).

2. With the throttle lever in the run position, the engine
speed should be around 2,300 RPM, therefore
engaging the centrifugal clutch.
NOTICE
ALWAYS move the throttle lever quickly without
hesitation, because increasing the engine speed slowly
causes the clutch to slip.
3. Using the direction control lever, move the machine
backward or forward (Figure 17). When the direction
control lever is pushed forward, the machine moves
forward. When pulled backward, the machine moves
backward.

4. When the direction control lever is the neutral position,
the machine vibrates staying at the same location
NOTICE
NEVER stop the engine suddenly while working at
high speeds.
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:
• Check the bottom plate to see if clay or equivalent
material has been lodge 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.
STOPPING THE ENGINE

ENGINE AIR CLEANER
DANGER
DO NOT use gasoline or low flash point
solvents for cleaning the air cleaner. The
possibility exists of fire or explosion which
can cause damage to the equipment and
severe bodily harm or even DEATH!
CAUTION
Wear protective equipment such as
approved safety glasses or face shields
and dust masks or respirators when
cleaning air filters with compressed air.
This engine is equipped with a replaceable, high-density
paper air cleaner element. See (Figure 21) for air cleaner
components.
1. Remove the air cleaner cover and foam filter element.
2. Tap the paper filter element several times on a hard
surface to remove dirt, or blow compressed air not
exceeding 30 psi (207 kPa, 2.1 kgf/cm2) through the
filter element from the inside out. NEVER brush off
dirt. Brushing will force dirt into the fibers. Replace the
paper filter element if it is excessively dirty.
