GENERAL INFORMATION
DEFINITION OF PLATE COMPACTOR
The Mikasa MVC-64VH/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.
The MVC-64VH/VHW is small and lightweight. It can be easily
handled by one person in confined areas. It has an accessible
front-mounted vibrator assembly. The sealed belt cover keeps
dirt and rocks away from the belt.
VIBRATORY PLATE
The vibratory plate of the compactor produces 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 of 5,600
vpm (vibrations per minute). The travel speed of the
compactor is approximately 82 ft./minute (25 meters/
minute).
ENGINE
The Mikasa MVC-64VH/VHW Plate Compactor is equipped
with a Honda GX120U1SM12 gasoline engine.

OPERATION
INITIAL START-UP
1. Place the fuel valve lever (Figure 11) in the ON position.
Figure 11. Fuel Valve Lever
2. Place the engine ON/OFF switch (Figure 12) in the
ON position.
NOTICE
The CLOSED position of the choke lever enriches the
fuel mixture for starting a COLD engine. The OPEN
position provides the correct fuel mixture for normal
operation after starting, and for restarting a warm
engine.
4. Place the throttle lever (Figure 14) halfway between
FAST and SLOW.
Figure 12. Engine ON/OFF Switch
3. Place the choke lever (Figure 11) in the OPEN position.
Figure 14. Throttle Lever
5. Grasp the starter grip (Figure 15) and slowly pull it
out. The resistance becomes the hardest at a certain
position, corresponding the compression point. Rewind
the rope a little from that point and pull out sharply.
NOTICE
DO NOT pull the starter rope all the way to the end.
DO NOT release the starter rope after pulling. Allow it
to rewind as soon as possible.

OPERATION
6. If the choke lever was moved to the CLOSED position,
slowly return the choke lever to the OPEN position.
7. If the engine has not started, repeat steps 1 through 5.
8. Before the compactor is put into operation, run the
engine for 3-5 minutes.
9. Check for abnormal engine noises or fuel leaks.
OPERATION
CAUTION
Make sure to follow all safety rules referenced in
the safety information section of this manual before
operating compactor. Keep work area clear of debris
and other objects that could cause damage to the
compactor or bodily injury.
1. Once the engine has started, move the engine throttle
lever quickly to the fast position.
2. With the throttle lever in the fast position, the engine
speed should be around 2,300 RPM therefore
engaging the centrifugal clutch.
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:
a. 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.
b. 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
CAUTION
NEVER stop the engine suddenly while working at
high speeds.
Normal Shutdown
NOTICE
ALWAYS move the throttle lever quickly without
hesitation, because increasing the engine speed slowly
causes the clutch to slip.
3. Firmly grasp the compactor's handle bar with both
hands. The compactor will begin moving forward.
4. 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.
1. Place the throttle lever (Figure 14) in slow position, and
listen for the engine speed to decrease.
2. Place the Engine ON/OFF switch (Figure 10) in the
OFF position.
3. Place the fuel valve lever (Figure 9) in the OFF position.
Emergency Shutdown
Move the throttle lever quickly to the SLOW position, and
place the Engine ON/OFF switch in the OFF position.

AIR FILTER
1. The air filter element should be cleaned because a
clogged air cleaner can cause poor engine starting,
lack of power and shorten engine life substantially.
2. To clean or replace air filter loosen the wing nut on the
air filter housing (Figure 17), remove the cover and take
out air filter cartridge. If only cleaning of the air filter
is desired blow through the air filter cartridge from the
inside, moving a jet of dry compressed air up and down
until all dust is removed.
CHANGING VIBRATOR OIL
1. When changing the vibrator oil, remove the drain plug.
2. Tip the compactor to drain the oil. Note that the oil will
drain more easily while it is hot.
3. Remember to use only 10W-30 motor oil when
replacing vibrator oil.
CHECKING/REPLACING THE V-BELT AND CLUTCH
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.
CHECKING V-BELT
Visually examine the V-belt (Figure 19) and determine if it
is full of tiny cracks, frayed, has pieces of rubber missing,
is peeling or otherwise damaged.
Also, examine the belt and determine if it is oil soaked or
"glazed " (hard shiny appearance on the sides of the belt).
Either of these two conditions can cause the belt to run hot,
which can weaken it and increase the danger of it breaking.
Figure 17. Air Filter
SPARK PLUG
1. Remove and clean the spark plug (Figure 16).
Figure 18. Spark Plug Gap
2. Adjust the spark gap to 0.028~0.031 inch (0.6~0.7 mm).
This unit has electronic ignition which requires no
adjustments.
If the V-belt exhibits any of the above wear conditions
replace the V-belt immediately.

MAINTENANCE
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.
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, visually check outer drum of the clutch for
seizure and "V" groove for wear or damage. Clean the "V"
groove as necessary. Wear of lining or shoe should be
checked regularly. If the shoe is worn, power transmission
becomes deficient and slipping will result.
PLATE COMPACTOR STORAGE
For storage of the plate compactor for over 30 days, the
following is required:
Drain the fuel tank completely or add STA-BIL to the fuel.
Run the engine until the fuel is completely consumed.
Completely drain the oil from the engine crankcase
and follow procedures described in the HONDA engine
Owner's Manual for engine storage.
Completely drain the compactor's hydraulic oil from the
vibrating case.
Clean entire plate compactor, especially the bottom plate
removing all dirt and foreign matter.
Cover plate compactor and engine with plastic covering
or equivalent and store in a clean, dry place.
WARNING
NEVER attempt to check the V-belt with the engine
running. Severe injury can occur if your hand (Figure 7)
gets caught between the V-belt and the clutch. Always
use safety gloves.
