MVH-304DSB— FEATURES

Plate Compactor

The Mikasa MVH-304DSB 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-304DSB 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 66 ft./minute (20 meters/
minute).

Engine

The Mikasa MVH-340DSB Plate Compactor is equipped with a
Yanmar L100EE-DEVMK3 diesel engine.

Controls

Before starting the MVH-340DSB Plate Compactor, identify and
understand the function of the controls and components as
indicated in Figure 3.

MVH-304DSB — MAINTENANCE

Engine Oil Replacement:

1. Replace engine oil, first in 25 hours of operation and every
50 to 100 hours afterwards.

2. Oil may be drained more easily when it is warm after
operation (For more details, see separate engine 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.

z

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.

z

Reinstalling the V-belt

Figure 21. V-Belt Check

Figure 19. Engine Air Filter and Element

2. To clean or replace air filter loosen the wing nut on the air
filter housing (Figure 19) 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.

CAUTION:

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 20).
Always use safety gloves.

CLUTCH
PULLEY

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.

CAUTION:

VIBRATOR
PULLEY

Figure 20 V-Belt Hazard

Checking and Replacing the V-Belt and Clutch

Whenever the compactor's vibration becomes
weak or lost during normal operation regardless
of operation hours, check the V-belt and clutch
immediately.

1. After 200 hours of operation, remove the belt cover to check
the V-belt tension (Figure 21). 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.
