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

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

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: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: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: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.
