MVC-88VGH/VGHW PLATE COMPACTOR — OPERATION AND SAFETY DECALS
Machine Safety Decals
The MVC-88VGH/VGHW 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.
MVC-88VGH/VGHW PLATE COMPACTOR — GENERAL INFORMATION
Definition of Plate Compactor
The Mikasa MVC-88VGH/VGHW 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-88GH/GHW 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
5800 vpm (vibrations per minute). The travel speed of the
compactor is approximately 17 meters/minute (56 ft./minute).
Engine
The Mikasa MVC-88VGH/VGHW Plate Compactor is equipped
with a Honda GX160U1QMX2 air cooled, 4-cycle gasoline
engine. The engine drives an eccentric weight at a high speed
to develop a compaction force. In addition this engine is equipped

Always be sure to check the engine oil level prior to starting
the engine.
Controls
Before starting the MVC-88VGH/VGHW 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-88VGH/VGHW Plate Compactor. The function of
each control is described below:
1.Water Tank Cap (VGHW 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 manuever the compactor.
5.Gasoline Engine – This plate compactor uses a HONDA
GX160U1QMX2 engine. Refer to the HONDA owner's
manual for engine information and related topics.
6.Belt Cover – Remove this cover to gain acess to the V-belts.
NEVER run the compactor without the V-belt cover. If the Vbelt 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 Tube (Sprinkler) – Supplies water to the soil via a
splash plate.
10.Water Shut-Off Valve – Turn this valve downward to let
water flow from the water tank to the water tube.
11.Water Tank (VGHW only) – Holds 13.7 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.

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.

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 fuel 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. DO NOT attempt to refuel the
compactor if the engine is
The Oil Alert System will automatically

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 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.

3.Clean foam element in warm, soapy water or nonflammable
solvent. Rinse and dry thoroughly. Dip the element in clean
engine oil and completely squeeze out the excess oil from the
element before installing.
1.After 200 hours of operation, remove the upper belt cover to
check the V-belt tension. Tension is proper if the belt bends
about 10 mm when depressed strongly with finger between
shafts. Loose or worn V-belts reduces power transmission
efficiency, causing weak compaction and reduces the life of
the belt itself.
CAUTICAUTI
CAUTION
CAUTICAUTI
Whenever the compactor's vibration becomes weak or lost
during normal operation regardless of operation hours, check
the V-belt and clutch immediately.
■
Replacing the V-belt
Remove the upper and lower belt covers. Engage an offset
wrench (13 mm) or the like to vibrator pulley (lower) fastening
bolt. Engage waste cloth or the like at midway of V-belt on the left
side and while pulling it back strongly, rotate the offset wrench
clockwise so that the V-belt will come off.
Figure 15. Air Cleaner
CHANGING VIBRATOR OIL
1.When changing the vibrator oil, remove the drain plug
located at the bottom- right of the vibrator (Figure 5), and
simply tip the compactor to drain the oil. Note that the oil will
drain more easily while it is hot. Remember to use only
10W-30 motor oil when replacing vibrator oil.
CAUTICAUTI
CAUTION
CAUTICAUTI
NEVER attempt to check the V-belt with the engine running.
Severe injury can occur if your hand (Figure 6) gets caught
between the V-belt and the clutch. Always use safety gloves.
■
Reinstalling the V-belt
Engage V-belt to lower vibrator pulley and push the V-belt to left
side of upper clutch and, in the same manner as in removal,
rotate offset wrench clockwise so that the V-belt goes back on.
■
Checking Clutch
Check the clutch simultaneously with V-belt checking. With belt
removed, check outer drum of the clutch for seizure and "V"
groove for wear or damage with your eyes. Clean the "V" groove
as necessary. Wear of lining or shoe should be checked with
running check. If the shoe is worn, power transmission becomes
deficient and slipping will result.
