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.
Figure 1 shows the location of the basic controls and components
of the MVC-80VH/VHW Plate Compactor. The function of each
control is described below:
1.Water Tank Cap (VHW Only) – Remove this cap to add
water to the water tank.
2.Fuel Tank Cap – Remove this cap to add fuel.
3.Lifting Bale – When lifting of the compactor is required
either by forklift, crane etc., tie rope or chain around this
lifting point.
4.Handle Bar – When operating the compactor use this
handle bar to maneuver the compactor.
5.Gasoline Engine – This plate compactor uses a HONDA
GX160U1SM12 engine. Refer to the HONDA owner's
manual for engine information and related topics.
l
6.Belt Cover – Remove this cover to gain access to the
V-belts. NEVER run the compactor without the V-belt cover.
If the V-belt cover is not installed, the possibility exists that
your hand may get caught between the V-belt and clutch,
causing serious injury and bodily harm.
7.Vibrating Plate – A flat, open plate made of durable cast
iron construction used in the compacting of soil.
8.Vibration Case – Encloses the eccentric, gears and
counter weights.
9.Water Shut-Off Valve (VHW only) – Turn this valve
downward to let water flow from the water tank to the water
tube.
10.Water Tank (VHW only) – Holds 13.8 quarts of water
(removable, no tools required).
The engine (Figure 2) 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.
1.Fuel Filler Cap – Remove this cap to add unleaded
gasoline to the fuel tank. Make sure cap is tightened
securely. DO NOT over fill.
DANGERDANGER

DANGERDANGER
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.
2.Throttle Lever – Used to adjust engine RPM speed (lever

3.Engine ON/OFF Switch – ON position permits engine
starting, OFF position stops engine operations.
4.Recoil Starter (pull rope) – Manual-starting method. Pull
the starter grip until resistance is felt, then pull briskly and
smoothly.
Explosive Fuel Hazard

, lever back toward operator -
5.Fuel Valve Lever – OPEN to let fuel flow, CLOSE to stop
the flow of fuel.
6.Choke Lever – Used in the starting of a cold engine, or in
cold weather conditions. The choke enriches the fuel
mixture.
7.Air Cleaner – Prevents dirt and other debris from entering
the fuel system. Remove wing-nut on top of air filter
cannister to gain access to filter element.
NOTE
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.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.
9.Muffler – Used to reduce noise and emissions.
10.Fuel Tank – Holds unleaded gasoline. For additional
information refer to engine owner's manual.
WARNINGWARNING
WARNING
WARNINGWARNING
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.
1.Read safety instructions at the
beginning of manual.
2.Clean the compactor, removing
dirt and dust, particularly the
engine cooling air inlet, carburetor
and air cleaner.
3.Check the air filter for dirt and dust. If air filter is dirty, replace
air filter with a new one as required.
4.Check carburetor for external dirt and dust. Clean with dry
compressed air.
5.Check fastening nuts and bolts for tightness. Loosened
screws or bolts due to vibration, could lead to unexpected
accident.
Engine Oil Check
1.To check the engine oil level, place the pump on secure
level ground with the engine stopped.
2.Remove the filler dipstick from the engine oil filler hole
(Figure 3) and wipe clean.
NOTE
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.
The Oil Alert System will automatically
stop the engine before the engine falls
below safe limits. Always be sure to
check the engine oil level prior to
starting the engine.

Vibrator Oil Check
1.Place the MVC-80VH/VHW plate compactor horizontally on
a flat surface. Make sure the compactor is level when checking the oil in the vibrator assembly.
2.Check vibrator oil level by removing the plug (vibrator oil gauge)
as shown in Figure 8. The oil level should be up to the oil plug.
The vibrator holds 140 cc (approximately 1 pint). IMPORTANT,
if oil is required, replace using only SAE10W-30 motor oil.

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:
■
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.
