equipment is for industrial use only.
The following safety guidelines should always be used
when operating the Mikasa MVC-90L Plate Compactor:
Safety:
■
DO NOT operate or service this equipment
before reading this entire manual.
■
This equipment should not be operated
by persons under 18 years of age.
■
NEVER operate this equipment without
proper protective clothing, shatterproof glasses, steel-toed

MVC-90L PLATE COMPACTOR — OPERATION AND SAFETY DECALS
Machine Safety Decals
The MVC-90L Plate Compactor is equipped with a number of safety decals. These decals are provided for operator safety and
maintenance information. The illustration below shows these decals as they appear on the machine. Should any of these decals
become unreadable, replacements can be obtained from your dealer.
Figure 2. Operation and Safety Decals
MVC-90L PLATE COMPACTOR — OPERATION & PARTS MANUAL — REV. #1 (11/01/05) — PAGE 11
MVC-90L PLATE COMPACTOR — GENERAL INFORMATION
Definition of Plate Compactor
The Mikasa MVC-90L 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-90L 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-90L 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.
Water Tank
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-90L Plate Compactor is equipped with a Robin
EH172YD4230 gasoline engine. The engine drives an eccentric
weight at a high speed to develop a compaction force.
Controls
Before starting the MVC-90L Plate Compactor identify and
understand the function of the controls and components.

MVC-90L PLATE COMPACTOR — COMPONENTS (PLATE COMPACTOR)
Figure 3. MVC-90L Plate Compactor Components
Figure 3 shows the location of the components and general
maintenance parts. The function of each component is described
below:
1. Fuel Tank Cap – Remove this cap to add fuel.
2. Lifting Bale – When lifting of the compactor is required
either by forklift, crane etc., tie rope or chain around this
lifting point.
3. Handle Bar – When operating the compactor use this
handle bar to manuever the compactor.
4. Engine – This plate compactor uses a Robin
EH172DYD4230 engine. Refer to the Robin owner's
manual for engine information and related topics.
5. Belt Cover – Remove this cover to gain acess to the Vbelts. NEVER run the compactor without the V-belt cover. If
the V-belt cover is not installed, the possibility exist that
your hand may get caught between the V-belt and clutch,
thus causing serious injury and bodily harm.
6. Vibrating Plate – A flat, open plate made of durable cast
iron construction used in the compacting of soil.
7. Vibration Case – Encloses the eccentric, gears and
counter weights.
8. Water Tube (Sprinkler) – Supplies water to the soil via a
splash plate.
9. Water Shut-Off Valve – Turn this valve downward to let
water flow from the water tank to the water tube.
10. Water Tank – Holds 5.6 quarts of water, built-in.
11. Water Tank Cap – Remove this cap to add water to the
water tank.

INITIAL SERVICING
The engine (Figure 3) must be checked for proper lubrication and
filled with fuel prior to operation. Refer to the manufacturers engine
manual for instructions & details of operation and servicing. The
engine shown above is a ROBIN engine, operation for other types
of engines may vary somewhat.
1. Throttle Lever – Used to adjust engine RPM speed (lever

CAUTION - Fueling The Engine
Adding fuel to the tank should be done only
when the engine is stopped and has had an
opportunity to cool down. In the event of a fuel
spill, DO NOT attempt to start the engine until
the fuel residue has been completely wiped
up, and the area surrounding the engine is dry.

NOTE
7. Muffler – Used to reduce noise and emissions.
CAUTION - Burn Hazard
Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas
while the engine is running or immediately after
operating. NEVER operate the engine with the
muffler removed.
8. Choke Lever – Used in the starting of a cold engine, or in
cold weather conditions. The choke enriches the fuel
mixture.
9. Engine ON/OFF Switch – ON position permits engine
starting, OFF position stops engine operations.
10. Spark Plug – Provides spark to the ignition system. Set
spark plug gap to 0.6 - 0.7 mm (0.028 - 0.031 inch) Clean
spark plug once a week.
11. Oil Dipstick /Filler Port– Remove to determine the amount
oil in engine crankcase. Add oil through this filler port.
12. Oil Sensor– In the event of low oil, this sensor will
automatically shut-down the engine.
13. Oil Drain Plug– Remove to drain crankcase oil.
Operating the engine without an
air filter, with a damaged air filter,
or a filter in need of replacement
will allow dirt to enter the engine,
causing rapid engine wear.

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.
quickly without hesitation.
Increasing the engine speed slowly
causes the clutch to slip and can
damage your clutch.
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:
z
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.
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.
Using the Compactor Sprinkler System
The MVC-90L 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.
NOTE
Whenever the compactor's vibration becomes weak or lost during
normal operation regardless of operation hours, check the V-belt and
clutch immediately.
