MVH-120GH — GENERAL INFORMATION  
Definition of Plate Compactor  
Frequency/Speed  
The Mikasa MVH-120GH 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.  
The compactor's vibrating plate has a frequency range between  
2500 to 6000 vpm (vibrations per minute). The forward and  
reverse travel speed of the compactor is approximately  
75 feet/minute (23 meters/minute).  
Engine  
The Mikasa MVH-120GH Plate Compactor is equipped with a  
Honda air-cooled, 4-cycle, gasoline engine.  
Vibratory Plates  
Controls  
The vibratory plates of the MVH-120GH produce low amplitude  
high frequency vibrations, designed to compact granular soils.  
Before starting the MVH-120GH Plate Compactor, identify and  
understand the function of the controls and components as  
indicated in Figure 1.  
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.  
ReversibleVibratory 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.

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.  
M
ake sure to follow all safety rules referenced in the  
safety section of this manual before operating compac-  
tor. Keepworkareaclearofdebrisandotherobjectsthat  
could cause damage to the compactor or bodily injury.  
DO NOT try to operate lever forcibly.The direction  
lever will operate normally when the engine is  
started and the compactor is in action.  
1. Grasp the compactor's hand grip (Figure 15), and move  
the engine throttle lever quickly from the turtle position  
(idle) to the rabbit position (full throttle) position.  
7. Compactor traveling speed may drop on soils which  
contain clay, however there may be cases where travel-  
ing 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:  
2. Run the compactor at full throttle (3,600 RPM's), the  
centrifugal clutch will automatically engage when the  
engine speed reaches 2,300 RPM.  
z
Check the bottom plate to see if clay or  
similar material has been lodged in the plate  
mechanism. If so, wash with water and  
remove.  
Always move the throttle lever quickly without  
hesitation, because increasing the engine  
speed slowly causes the clutch to slip.  
z
z
Keep in mind that the compactor does not  
work as efficiently on clay or soils that have  
a high moisture content level.  
3. To make the compactor move in the forward direction  
push the travel lever (Figure 15) forward.  
If the soil has a high moisture level, dry soil  
to appropriate moisture content level or carry  
out compaction twice.

MVH-120GH — MAINTENANCE  
Engine Oil Replacement:  
z
Replacing the V-belt  
1. Replace engine oil, first in 20 hours of operation and every  
100 hours afterwards.  
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 ofV-belt on the left  
side and while pulling it back strongly, rotate the offset wrench  
clockwise so that theV-belt will come off.  
2. Oil may be drained more easily when it is warm after  
operation (For more details, see separate HONDA Owner's  
Manual).  
Air Filter  
z
Reinstalling the V-belt  
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.  
EngageV-belt to lower vibrator pulley and push theV-belt to left  
side of upper clutch. In the same manner as in removal, rotate  
offset wrench clockwise so that theV-belt goes back on.  
z
Checking Clutch  
Check the clutch simultaneously withV-belt checking. With belt  
removed, visually check outer drum of the clutch for seizure and  
"V" groove for wear or damage.Clean the "V" groove as necessary.  
Regularly check the lining or shoe for wear. If the shoe is worn,  
power transmission becomes deficient and slipping will result.  
CAUTION  
Wheneverthecompactor'svibrationbecomesweakorlost  
during normal operation regardless of operation hours,  
check theV-belt and clutch immediately.  
Vibrator Oil Level Check  
CAUTION  
Figure 16. Air Filter  
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  
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.  
l
removed.  
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.  
CAUTION  
NEVER attempt to check theV-belt with the engine run-  
ning. Severe injury can occur if your hand gets caught  
between the V-belt and the clutch. Always use safety  
gloves.  
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.  
Checking and Replacing the V-Belt and Clutch  
1. After 200 hours of operation, remove the upper belt cover to  
check theV-belt tension.Tension is proper if the belt bends  
about 10 mm when depressed strongly with finger between  
shafts. Loose or worn V-belts reduce power transmission  
efficiency, causing weak compaction and reducing the life  
of the belt itself.  
Use engine oil 10W-30 for this lubrication.

2. After draining, reconnect the hydraulic hose to vibrator.  
CAUTION  
3. Fill oil through breather hole of hand pump. (capacity: about  
300 cc).Use ShellTellus Oil #46 or equivalent.  
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.  
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.  
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.  
Troubleshooting  
See Tables 7 (engine) and 8 (plate compactor) for engine and  
plate compactor troubleshooting guide.  
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.
