GENERAL INFORMATION
Plate Compactor
The Mikasa MVH306GH 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 MVH306GH 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 4400
vpm (vibrations per minute). The forward and reverse travel speed
of the compactor is approximately 75 ft./minute (23 meters/
minute).
Engine
The Mikasa MVH306GH Plate Compactor is equipped with a
GX270K1-SMX2 (recoil start) gasoline engine.
Controls
Before starting the MVH306GH Plate Compactor, identify and
understand the function of the controls and components as
indicated in Figure 4.

MAINTENANCE
Checking and Replacing the V-Belt and Clutch
1. After 200 hours of operation, remove the belt cover to check
the V-belt tension (Figure 30). Tension is proper if the belt
bends about 3/8”(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 30. V-Belt Check
Replacing the V-belt
Remove the belt cover. Engage an offset wrench 3/4”(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 V-belt will come off.
Vibrator Oil Level Check
NOTICE
Always clean the area around the vibrator oil level check plug
before removing oil check plug. This will prevent dirt and
debris from entering the system.
1. In every 100 hours of operation, with the machine positioned
horizontally, use a 3/4” (19 mm) wrench and remove vibrator
oil level check plug (Figure 31). Visually inspect and see if
vibrator oil level is up to filler port. Be sure to clean area
around check hole to prevent dirt and dust from entering.
Figure 31. Vibrator Oil Drain and Check Plugs
Draining Vibrator Oil
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
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.
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.
CAUTION
Whenever the compactor's vibration becomes weak or lost
during normal operation regardless of operation hours,
check the V-belt and clutch immediately.
1. Replace vibrator oil after first 200 hours and in every 1,000
hours of operation.
2. Position handle bar vertically (storage position).
3. Using a 14 mm wrench remove the vibrator oil drain plug
(Figure 31) from the vibrating plate assembly.
NOTICE
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.
4. After vibrator oil has been completely drained from machine,
fill with 10W-30 motor oil to the appropriate safe operating
level (Figure 31).
5. Reinstall drain plug into vibrating plate assembly. Apply seal
tape or Loctite #575 to thread portion of drain plug.
Draining Hydraulic Oil
1. Disconnect the hydraulic hose connected to the hydraulic
oil cylinder (Figure 32).
MVH306GH PLATE COMPACTOR — OPERATION AND PARTS MANUAL — REV. #8 (01/31/14) — PAGE 23
CAUTION
Make sure hydraulic oil 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.
3. Loosen bleeder plug located at top of hydraulic cylinder on
side of vibrator (Figure 35). Air remaining in the circuit will

2. Push the travel lever back and forth to drain the hydraulic oil
from the hand pump (hydraulic oil reservoir).
3. After draining hydraulic oil, reconnect hydraulic oil hose to
cylinder.
4. Place handle in upright position. Pull travel lever all the way
back (reverse), and using a rope, secure travel lever to hand
grip.
Adding Hydraulic Oil
