MVH-150GH/D GENERAL INFORMATION

Definition of Plate Compactor

The Mikasa MVH-150GH/D is a walk behind, reversible plate

compactor design 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-150GH/D 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 5600

vpm (vibrations per minute). The forward and reverse travel speed

of the compactor is approximately 75 ft./minute (23 meters/

minute).

Engine

The Mikasa MVH-150GH/D Plate Compactor is equipped with

an Honda air cooled, 4-cycle gasoline engine. The MVH-150D

Plate Compactor is equipped with a Yanmar Air cooled, 4- cycle

diesel engine.

Controls

Before starting the MVH-150GH/D Plate Compactor identify and

understand the function of the controls and components as

indicated on page 11 (Figure 1).

MVH-150GH/D — PARTS & OPERATION MANUAL — REV. #2 (12/04/06) — PAGE 11

5. Handle Bar (working position) – When operating the

compactor, this handle is to be in the downward position.

6. Handle Bar (stored position) – When the compactor is

to be

stored

, move the handle bar to the upright position.

7. Engine – This plate compactor can use either a HONDA

GX200 gasolineengine or a ROBIN DY23-2D diesel

engine. Refer to the respective owners manual for engine

information and related topics.

8. Belt Cover – Remove this cover to gain access to the V-

belts. NEVER run the compactor without the V-belt cover. If

the V-belt cover is not installed, the possibility exist that

your hand may get caught between the V-belt and clutch,

thus causing serious injury and bodily harm.

9. Vibration Case – Encloses the eccentric, gears and

counter weights.

10. Forward & Reverse Lever –

Push

the lever forward, the

compactor will move in a forward direction,

pull

the lever

backwards, the compactor will move in backwards direction.

Placing the lever in the middle (midway) will cause the

compactor not to move (neutral).

MVH-150GH/D — OPERATION

Operation

1. Grasp the compactor's hand grip (Figure 15), and move the

engine throttle lever quickly to the

fast

position.

2. With the throttle lever in the fast position, the engine speed

should be around 2,300 RPM, therefore engaging the cen-

trifugal clutch.

NOTE

Always move the throttle lever quickly without

hesitation, because increasing the engine speed

slowly causes the clutch to slip.

3. To make the compactor move in the forward direction push

the travel lever ( Figure 15) forward.

Figure 15. Direction Lever

4. To make the compactor move in the reverse direction pull the

travel lever ( Figure 15) backwards.

5. Firmly gasp the compactor's hand grip, the compactor will

begin moving in the desired position when the direction lever

has been placed in the desired position.

6. Slowly walk behind the compactor and be on the lookout for

any large objects or foreign matter that might cause damage

to the compactor or bodily injury.

CAUTION:CAUTION:

CAUTION:

Make sure to follow all safety rules referenced

in the safety section of this manual before oper-

ating compactor. Keep work area clear of debris

and other objects that could cause damage to

the compactor or bodily injury.

CAUTION:CAUTION:

CAUTION:

z

Moving the direction lever back and forth

a few times after the engine has been

turned off, will cause the lever to be

locked in the forward position.

z

DO NOT try to operate lever forcibly. The

direction lever will operate normally

when the engine is started and the

compactor is in action.

7. Compactor traveling speed may drop on soils which contain

clay, however there may be cases where traveling speed

drops because the compaction plate does not leave the

ground surface easily due to the composition of the soil. To

rectify this problem do the following:

z

Check the bottom plate to see if clay or

equivalent material has been lodge in the

plate mechanism. If so, wash with water and

remove.

z

Remember the compactor does not work as

efficiently on clay or soils that have a high

moisture content level.

z

If the soil has a high moisture level, dry soil

to appropriate moisture content level or carry

out compaction twice.

MVH-150GH/D — PARTS & OPERATION MANUAL — REV. #2 (12/04/06) — PAGE 19

Engine Oil Replacement:

1. Replace engine oil, first in 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 16), 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.

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

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.

z

Checking Clutch

Check the clutch simultaneously with V-belt checking. With belt

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.

CAUTION:

Whenever the compactor's vibration becomes

weak or lost during normal operation regard-

less of operation hours, check the V-belt and

clutch immediately.

MVH-150GH/D MAINTENANCE

Vibrator Oil Level Check

1. In every 300 hours of operation, with the machine positioned

horizontally, remove vibrator oil level check plug (Figure 5)

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.

2. In every 300 hours of operation, replace oil (capacity 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.

CAUTION:

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:

NEVER attempt to check the V-belt with the

engine running. Severe injury can occur if your

hand (Figure 7) gets caught between the V-belt

and the clutch. Always use safety gloves.

Checking and Replacing the 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 reduces power transmission

efficiency, causing weak compaction and reduces the life of

the belt itself.

2. After draining, reconnect the hydraulic hose to vibrator.

3. Fill oil through breather hole of hand pump. (Capacity: About

300 cc). Use

Shell Tellus Oil #46

or equivalent

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.

Figure 17. Hydraulic Hose

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 6), remove

plug of breather (24 mm wrench) and disconnect vibrator

side of hydraulic hose (Figure 17) at vibrator cylinder. With

travel lever placed in the

FORWARD

position, drain

hydraulic oil in the pump.

CAUTION:CAUTION:

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.

Troubleshooting

See Tables 7 (engine) and 8 (plate compactor) on proceeding

pages for engine and plate compactor troubleshooting guide.
