2. Machine Applications, Structure and Power Transfer
【Applications】
【Structure】
【Power Transfer】
Mikasa vibration roller is that powerful single axis lets vibrate both drums and compact the
ground.
Compaction is more effective for most of the ground except soft ground kept much moisture.
So various applications such like soil & sand, soil, gravel and asphalt compactions can be
applied.
Vibration system and traveling system are both independent, and static pressure compaction
and working with some degrees of inclined area can also possible.
Wide range compaction is also applicable with working efficiency.
But the machine does not comply with the area, where is already well compacted and with
which hard soil more than the performance of the roller. It causes serious damage for the roller.
Be sure to escape the roller from the above working conditions.
The upper part of the machine consists of engine , hydraulic pump, oil tank, electromagnetic
clutch, water tank, handlebar. The upper part of the machine is fixed to frame to connect with
lower part through shock absorbing rubber.
The machine lower part consists of a vibrator part, a drum part and a frame supporting vibrator.
The machine lower part has vibrator, drum, frame. Vibrator unit generates vibration in-between
both drums, each of which is traveled by each hydraulic motor. Frame is consisted of as main
body.
A water-cooled single cylinder diesel engine or an air-cooled one is mounted on, of which
power output is transferred through centrifugal clutch.
A centrifugal clutch is engaged with by the acceleration of engine speed.
Rubber Coupling with pins built-in Clutch Drum transfers the engine power to Hydraulic Pump
for traveling.
Hydraulic Pump generates hydraulic pressure through out hydraulic hose calling from oil tank.
Hydraulic pressure is transferred to hydraulic motor built-in Drum Bracket to move the drum.
Traveling speed and Forward-Reverse motion is adjusted by the incline motion of Travel
Lever. The adjustment of Control Cable can let trunnion spin of hydraulic pump, and the one
of Body side can let Handle Bar move slightly.
Centrifugal Clutch Drum united with V-pulley(1), is connected through V-belt to V-pulley(2) at
the counter axis end. Output Axis of Electromagnetic Clutch is connected to V-pulley(3) to
rotate, and transferred to V-pulley(4) to switch Vibration system.
The vibration generated by Vibration unit is transferred to Side Plate, Drum Bracket and Drum
in order, to compact the ground with Dynamic Vibration Force.

CAUTION:
CAUTION:
4.10 Precaution to avoid water hammer in cylinder
For machine in outdoor storage, always put the cover on top to protect the
engine muffler and air cleaner from dew and rain.
Protect engine air cleaner and muffler from any invasion of rain or water jet
spray. Otherwise, rain or water jet spray goes into engine cylinder and water
hammer phenomenon happens. If engine starts, the crank shaft rotates
normally, but the piston does not go up in compression process, because of
water remained in cylinder.
Higher compressed engine like Diesel engine leads water hammer easily
because of it happens with small water volume.
If water goes into cylinder, water hammer phenomenon is a main reason of
trouble.

4.11 Precaution of electro-magnetic clutch for vibration
Stop the engine securely and then start inspection.
Take special attention not to convolute any cloth and hand from rotation
parts(Belt, Pulley and etc.)
Do not touch any rotation part with hand while machine running.
Do not pour water or apply grease, to avoid electric shock in leaking.
Electro-magnetic clutch is the dry type. If grease adheres on surface, friction
torque drops remarkably.
Do not touch fingers and hand with even in stop position.
Electro-magnetic clutch activate easily by switching “ON” and “OFF” .
Pay special attention not to touch or pinch to rotational part.
The temps. on clutch surface go up contingently by turning on electricity.
The temps. on clutch surface go up until 90
O
C -100
O
C because it heats by slip
resistance and built-in coil heat.
So keep the slip resistance temps not over 80
O
C on outer surface of clutch.
In case, do not touch the surface to avoid burning injury.
Electro-magnetic clutch is made of soft material for its nature.
Dent by unreasonable force or deformation leads to improper activation or
lack of torque.
Built-in fuse works in wire harness near electro-magnetic clutch, if over
amperage flows. However, engine starts normally, and runs to travel at
2,500 min-1(2,500r.p.m.) without problem. Check fuse to replace if no
vibration.

●
Align throttle lever with the position for Operation.
Travel lever should be in neutral and vibration lever
in OFF positions.
Open fuel cock.
8-2 Traveling
●
Insert the key into the key switch and turn the key to
"ON" (Operation) position. Make sure that a buzzer
goes off when the key is turned to ON.
Stop the key at "GL" (Preheat) position to preheat for
5 seconds. (With the key at "GL" position, the glow
lamp next to the horn button lights up for five sec.,
then it will go out.)
After preheating, turn the key further to the right to
"ST" (Start) position. Starter will run to start the
engine. Immediately after the engine is started, take
your hand off the key.
After the engine revolution has increased, the buzzer
will stop. Because a safety status switch is installed,
the cell motor will not run unless the driving lever is at
the stop position.
When use decompression, two
people confirm security each other.
WARNING:
After starting, continue warm-up run for about 3
to 10 minutes. In cold weather particularly this
warm up is essential. Check for gas leakage or
any abnormal noise during this interval.
●
If buzzer does not cease to sound after engine
has started, shutdown engine immediately and
check engine oil level. This buzzer has the
function of engine oil warning as well.
It is only after the engine rotation is stopped that
you can use the key switch. When repeating key
operation more than three times, take about one
minute break before restarting.
While the engine is running, never try to set the
key switch to "ST" position.
In case if a wire or a strap is attached to the key,
it might happens that the key does not move
back from the (Start) position, resulting in cell
motor burnout by overrun.
When starting with the cell motor, normally, there
is no need to use decompressor. However, you
may use the decompressor for easy starting
when the temperature is low or the battery is
getting weak.

With throttle lever fully opened, increase the
engine rotation. (Fig.7)
Pushing travel lever slightly forward, causes the
roller to travel forward at micro speed. Pushing it
further, increases the travel speed. Depending on
how you move the travel lever, travel speed can
be varied steplessly between 0 and 3 km/h (for
both forward and reverse). Pulling the lever back
causes the roller to travel backward. (Fig.8)

Unloading procedure
(Fig.17 and 18)
Besides emergency, do not take
the next operation. There is fear to cause serious
obstacle or death accident when takes the wrong
handling.
WARNIG:
●
After stopping engine, if you have to move the
roller by pushing it manually, loosen bolt of
by-pass valve on oil pump by one rotation, which
will cause hydraulic brake to be disengaged so
that you can move it with less effort.
●
After moving, do not forget to tighten the bolt
back again. Tightening torque is55 to 70 kgf-cm.
WARNING:
Be careful with the handling of
tightening torque.
Do not tighten much, because it damage
needle-valve, and leak a hydraulic oil.
When a hydraulic oil does leak, there is danger to
run by itself even loose slope. In addition,
performance deteriorates in driving, and there is
the fear that operator becomes dangerous.
CAUTION:
Never tow this roller by means
of vehicle or the like. It will damage hydraulic
system.
WARNING:
Never conduct this unloading
procedure on slope. It may cause the roller to
roll down with its own weight if parking brake or
blocking is deficient.
