MVH-402GHB — FEATURES

Plate Compactor

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.

Controls

Before starting the MVH-402GHB Plate Compactor, identify and
understand the function of the controls and components as
indicated in Figure 3.

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.

Figure 24. V-Belt Hazard

MQ-MIKASA MVH-402GHB PLATE COMPACTOR — OPERATION & PARTS MANUAL — REV. #0 (12/17/03) — PAGE 21

MVH-402GHB — 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 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.

Figure 26. Vibrator Oil Maintenance

Figure 27. Bleeder Plug

PAGE 22 — MQ-MIKASA MVH-402GHB PLATE COMPACTOR — OPERATION & PARTS MANUAL — REV. #0 (12/17/03)

MVH-402GHB — MAINTENANCE

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.

Figure 28. Hydraulic Oil Maintenance

2. Clean the filter with light oil.

3. Reinstall the drain plug to the oil tank. Apply seal tape or
Roctite #575 to thread portion.

4. Fill tank with hydraulic oil. (Capacity: About 2,500 cc). Use

Shell Tellus Oil #46

5. After filling tank, temporarily install cover. Loosen bleeder
plug located at the top of the cylinders on side of vibrator
(Figure 27). Air remaining in the circuit will be forced out of
the bleeder plug.

6. Tighten the breather plug. Check oil level in the tank again.

7. Install the cover of oil tank. Coat packing with liquid packing
such as Threebond #1215. Use Loctite #242 for mounting
screw.
