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.

Gasoline Engine – This plate compactor uses a HONDA  
GX160 engine. Refer to the HONDA owner's manual for  
engine information.  
Figures 1 and 2 show the location of the controls, indicators and  
general maintenance parts. The function of each control is  
described below:  
8.  
Belt Cover – Remove this cover to gain access to theV-belts.  
NEVER run the compactor without theV-belt cover.If theV-  
belt cover is not installed, your hand may get caught between  
theV-belt and clutch, thus causing serious injury and bodily  
harm.  
1.  
Breather Cap – Remove this cap to bleed (remove air)  
the hydraulic system. When replacing hydraulic oil, use  
l
"Shell Tellus #46 or equivalent".  
2.  
3.  
4.  
Hand Grip – When operating the compactor use this hand  
grip to maneuver the compactor.  
9.  
Vibration Case – Encloses the eccentric gears and counter  
weights.  
Handle Lock – Pull handle bar downward (working  
position), then pull handle lock to lock handle bar in place.  
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).  
Vibration Case Oil Level Check Plug – Remove this plug  
to check the vibration case oil. Oil level should be all the  
way up to the filler port. When replacing vibration case oil,  
use 10W-30 engine oil.  
5.  
6.  
Handle Bar (working position) – When operating the  
compactor, this handle is to be in the downward position.  
11. Throttle Control – Move the throttle lever to the rabbit  
position for full throttle (max RPMs). For engine idle, move  
the throttle lever to the turtle position.  
Handle Bar (stored position) – When the compactor is  
to be stored, move the handle bar to the upright position.
