GENERAL INFORMATION
DEFINITION OF PLATE COMPACTOR
The Mikasa MVH120VGH is a walk-behind, reversible plate
compactor designed for the compaction of sand and clay.
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
soil compacting for road, embankments and reservoirs as
well as backfilling for gas pipelines, water pipelines and
cable installation work.
ECCENTRIC WEIGHTS
A set of rotating eccentric weights within the vibrator case
produces low amplitude high frequency vibrations, designed
to compact granular soil. The rotation of the weights are
controlled hydraulically through a lever on the control handle.
Changing the position of the lever allows smooth transition
between forward and reverse travel.
The resulting vibrations cause forward motion. The engine
and handle are vibration-isolated from the vibrating plate.
The heavier the plate, the more compaction force it
generates.
ANTI-VIBRATION HANDLE SYSTEM (AVT)
This compactor is equipped with advanced anti-vibration
handle design that reduces vibration to the operator by up
to 50% compared to other plate compactors.
FREQUENCY/SPEED
The compactor's vibrating plate has a frequency range of
6000 vpm (vibrations per minute). The forward and reverse
travel speed of the compactor is approximately 75 feet/
minute (23 meters/minute).
ENGINE
The plate compactor is equipped with a Honda
GX160U1SMX4 air-cooled, 4-cycle, gasoline engine.

MAINTENANCE
ENGINE OIL REPLACEMENT
1.Replace engine oil, in first 20 hours of operation and
every 100 hours afterwards.
2.Oil may be drained more easily when it is warm after
operation (For more details, see separate HONDA
Owner's Manual).
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.
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. 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. Regularly check the lining or shoe
for wear. If the shoe is worn, power transmission becomes
deficient and slipping will result.
Whenever the compactor's vibration becomes weak or lost
during normal operation regardless of operation hours,
check the V-belt and clutch immediately.
VIBRATOR OIL LEVEL CHECK
1.In every 300 hours of operation, with the machine
Figure 17. Air Filter
2.In every 300 hours of operation, replace oil (capacity
CHECKING AND REPLACING V-BELT AND CLUTCH
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 reduce
power transmission efficiency, causing weak
compaction and reducing the life of the belt itself.
Always clean the area around the vibrator oil level
check hole before removing oil check plug. This
will prevent dirt and debris from entering the system.
CAUTION
positioned horizontally, remove vibrator oil level check
plug (Figure 6) off vibrator (14 mm wrench) and see if
oil is up to filler port. Be sure to clean area around
check hole to prevent dirt and dust from entering.
400 cc). For draining oil through level check hole, have
the machine inclined with a sleeper or the like placed
under the compaction plate on opposite side.
* Use engine oil 10W-30 for this lubrication.

MAINTENANCE
CAUTION
Make sure hydraulic oil in hand pump is at a normal
save operating level. DO NOT over fill. Over filling
(excessive oil) will cause excess oil to blow out of
breather plug.
HYDRAULIC OIL
Check hydraulic oil in every 100 hours of operation. With
handle bar positioned vertically (storage position), remove
breather plug (Figure 1) off the top of hydraulic pump and
check for proper oil level.
Replace hydraulic oil after first 200 hours and in every 1,000
hours of operation.
Replacing Hydraulic Oil
1.After removing plug cap of hand pump (Figure 7),
remove plug of breather (24 mm wrench) and disconnect
vibrator side of hydraulic hose (Figure 18) at vibrator
cylinder. With travel lever placed in the
position, drain hydraulic oil in the pump.
FORWARD
STORAGE
For storage of the pump for over 30 days, the following is
required:
Drain the fuel tank completely.
Run the engine until the fuel in the injection system 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.
2.After draining, reconnect the hydraulic hose to vibrator.
Figure 18. Hydraulic Hose
3.Fill oil through breather hole of hand pump. (capacity:
about 300 cc). Use
4.Removing breather plug at vibrator cylinder causes oil
to flow out of breather hole in a while. When aeration
disappears, replace the plug and tighten securely.
5.Replace breather plug of hand pump and fit the plug
cap. After making sure that oil in pump is at proper
level, replace the breather plug.
