The Mikasa MVH-402GHB is a walk-behind, reversible plate
compactor designed for the compaction of sand, clay 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
soil 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 MVH-402GHB produce low amplitude
high frequency vibrations, designed to compact granular soils.
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.
Reversible Vibratory Plates
Reversible vibratory plates have two eccentric weights that allow
a smooth transition for forward and reverse travel, plus increased
compaction force as the result of dual weights.
Due to their weight and force, reversible plates are ideal for
semi-cohesive soils.
Frequency/Speed
The compactor's vibrating plate maximum frequency is 4200
vpm (vibrations per minute). The forward and reverse travel speed
of the compactor is approximately 75.5 ft./minute (23 meters/
minute).
Engine
The Mikasa MVH-402GHB Plate Compactor is equipped with a
HONDA GX390K1 gasoline engine.

NEVER attempt to check the V-belt with the
engine running. Severe injury can occur if your
hand gets caught between the V-belt and the
clutch (Figure 24). Always use safety gloves.
1.After 200 hours of operation, remove the belt cover to check
the V-belt tension (Figure 25). 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.
Figure 25. V-Belt Check
z
Replacing the V-belt
Remove the belt cover. Engage an offset wrench (19 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 Vbelt will come off.
Vibrator Oil Level Check
CAUTION :
1.In every 100 hours of operation, with the machine positioned
horizontally, remove vibrator oil level check plug (Figure
26) off vibrator (19 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.
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.
z
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.
z
Checking Clutch
Check the clutch simultaneously with V-belt checking. With belt
cover 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.
z
Replacing Clutch
Remove V-belt. Remove bolt at engine power output by giving a
shock to an engaged wrench (tapping with hammer or the like)
and rotating bolt counterclockwise. Remove clutch with a pulley
extractor. To reinstall, reverse the procedure.
2.In every 300 hours of operation, replace oil (capacity 1,500
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.
Hydraulic Oil
1. Check hydraulic oil in every 100 hours of operation. With
handle bar positioned vertically (storage position), remove
bleeder plug (Figure 27) off the top of hydraulic pump and
check for proper oil level.
CAUTION :
Whenever the compactor's vibration becomes
weak or lost during normal operation regardless of operation hours, check the V-belt and
clutch immediately.
2. Replace hydraulic oil after first 200 hours and in every 1,000
hours of operation.
CAUTION :
Make sure hydraulic oil i is at a normal safe
operating level. DO NOT over fill. Over filling
(excessive oil) will cause excess oil to blow
out of breather plug.
Replacing Hydraulic Oil
1.Remove the drain plug (Figure 28) at the bottom of the oil
tank with a 6 mm hex wrench and drain the hydraulic oil.
Battery Maitenance
1.Check the battery terminals periodically to ensure
that they are in good condition.
2.Use wire brush or sand paper to clean the battery
terminals.
3.Check battery for cracks or any other damage. If white
pattern appears inside the battery or paste has
accumulated at the bottom, replace the battery.
4..If the machine will not be in operation for a long
period of time, store in cool dry place and check the
battery charge level every month to maintain the
performance of the battery.
Battery Cable Connection
1.Take off the battery cover by removing the M6 nuts (Figure
29).
2.When removing cable, disconnect the ground side (normally
negative) first (Figure 29).
3.When installing cable connect the ground side (normally
negative) last.
