1．INTRODUCTION

2．APPLICATION, STRUCTURE AND POWER TRANSMISSION

This machine, weighing more than 200kg to more than 400kg, is a compactor with back and forth motion. The strong vibra­tion from the two-axes pendulum structure inside the vibrator changes the machine’s motion into straight back and forth
motion. The machine compacts through this motion.
The machine has tightening and compacting effect for all ground types other than the soft soil with high water percentage.
Because the machine is capable of straight back and forth movement, it works very effectively in grooved structures. Also,
since the work efficiency of this machine is high, it is suitable for compacting of a large area. The machine also works well
for flattening and leveling rough ground surface with irregularities created by the use of a powerful tamping rammer.
The machine can be used widely for heavy compacting works such as base work as well as finishing work for asphalt paving.

Do not use this machine on ground with a high water percentage and, in particular, do not use on clay because the machine
will not advance. Use this machine for compacting earth and sand mixtures, soil, sand or gravel. Do not use this machine for
other type of work.

The upper part of the machine consists of an engine, handle, belt cover and exterior frame. The upper part of the machine
is fixed to the vibrating plate of the lower part via an anti-vibration rubber. The lower part of this machine consists of a vibrat­ing plate that incorporates a vibrator, there are two pendulums. The phase of those pendulums is changed by hydraulic
pressure.
The hydraulic cylinder for the vibrator is connected with a hydraulic hose to the hydraulic pump, which is directly connected
to the drive lever.

Power is provided by an air-cooled single-cylinder 4-cycle gasoline engine or diesel engine. The engine output shaft is
equipped with a centrifugal clutch. The centrifugal clutch is engaged when the engine speed increases. V-pulley is incorpo­rated to the centrifugal clutch drum, and power is transmitted via the V-belt to the V-pulley on the vibrator side.
Through this process, the engine revolution is changed to the pendulum revolution suitable for compacting.
The vibrator pulley rotates the pendulum axis of the drive side. The two pendulums inside the vibrator are fixed to the two
pendulum axes that are positioned in parallel and are connected with the gear. The two axes rotate in opposite directions at
the same speed to generate vibration.
There is a spiral groove on the inner periphery of the gear assembled on the pendulum axis to be driven. This groove serves
as a key groove to let the guide pin slide to the axis direction. This guide pin is connecting the two pendulum axes. The phase
of the two pendulums is changed by the axial sliding of the guide pin. The change in phase causes the vibration to change
directions, thus changing the speed and travel direction of the machine.
Hydraulic pressure is used for the axial movement of the guide pin. At the end of the groove where the guide pin is attached,
a piston is installed. When the oil level rises inside the hydraulic cylinder on the vibrator side and the pressure increases, the
piston is pushed. Then the axis connected to the piston is pushed, which causes the guide pin attached to the axis to move,
resulting in a change in phase.
The operator of the machine, by using the back and forth motion lever of the handle, can adjust the oil quantity and pressure
by the connected hand pump to get the travel speed suitable for the work.

This operation manual describes the proper operation, basic inspection and maintenance procedures of the reversible
compactor. Please read this operation manual before use in order to maximize the excellent performance of this
machine and make your work more efficient and effective.
After reading the manual, please keep it in a handy location for easy reference.
For the handling the engine, please refer to the separate engine operation manual.
For inquiries about repair parts, parts lists, service manuals, and repairs, please contact the store where you purchased
the product, our sales office, or the Mikasa Parts Service Center. For parts lists, please visit our homepage at:

Always refuel in a well ventilated area.
Make sure to stop the engine and wait until the engine cools down when refueling.
Select a flat surface area with no flammable material around for refueling. Be careful
not to spill the fuel. Wipe off well if there is any spill.
Never put fire near the machine during refueling. (Especially, be careful about
smoking.)
If you fill to the top of the fuel tank inlet, fuel might spill out from the tank, and it
becomes dangerous
After refueling, tighten the tank cap well.

Do not run the machine in an unventilated location, such as indoors or inside a tunnel. The exhaust gas
from the engine contains toxic gases such as carbon monoxide and is very hazardous.
Do not operate the machine near open flames.

Check each part to see if it is tightened properly. Vibration causes loosening of bolts, which results in
unexpected serious malfunctions of the machine. Tighten the bolts securely.

Before starting the machine, make sure it is safe to start by checking your surroundings for people and
objects.
Always pay attention to your footing. Work in an area where you can maintain a good balance of the
machine and a safe comfortable posture.
The engine and muffler become very hot. Do not touch immediately after the machine stops because
they are still very hot.
If you notice deterioration of machine operation during your work, stop your work immediately.
Before moving away from the machine, be sure to turn the engine off. Also when the machine is
transported, stop the engine and close the fuel cock.
For a machine with cell starter specification, do not operate without the battery. If you operate without the
battery, electrical system failure might occur.

Before lifting, check the machine parts (especially the hook and anti-vibration rubber) for any damage
and loosened or missing bolts.
Stop the engine and shut the fuel cock while lifting.
Use a sufficiently strong wire rope.
For lifting, use only one point hoisting hook, and do not lift at any other part.
When the machine is hoisted, never let people or animals come underneath.
For safety reasons, do not lift to a height that is higher than necessary.

Stop the engine during transportation.
Transport after the engine and the machine are cooled down.

Appropriate maintenance is required to ensure safe and efficient operation of the
machine. Always pay attention to the machine’s condition and keep it in good
condition. Pay special attention to the parts used for lifting, if they are not maintained
properly, it might result in a serious accident.
Start maintenance work after the machine has cooled down completely. The muffler,
in particular, becomes very hot, and there is a danger of burn. The engine, engine oil
and vibrator also become very hot. Be careful not to get burned.

Always stop the engine before inspection and adjustment. If you are caught in a
rotating part, serious injury might occur.
After maintenance work, check the security parts to see if they are securely installed.
Special attention should be paid when checking bolts and nuts.
If disassembly is involved in maintenance, refer to the maintenance instruction
manual to make your work safe.

If the battery fixing bolts have been removed, put them back and tighten securely to
fix the battery.
If used with the battery not fixed properly, contact with the battery terminal might
occur, leading to electric shock and electric leak, or breakage of the battery might
occur by the impact and vibration from outside, resulting in battery fluid leakage.
The gas from the battery might cause an explosion. Do not generate sparks or bring
flames near the battery.
Never put the positive terminal and negative terminal come into contact. Sparks will
be generated, and ignition might occur.

Be careful when handling the battery fluid because it is very toxic. If the battery fluid
gets on your skin, eye, or clothes, rinse it off with plenty of water and consult with a
doctor.

When this machine is used on ground that con­tains clay, the ground surface tends to stick to
the vibrating board, and the machine travel
speed becomes slower. In this case, check the
bottom of the vibrating board to see if there is
any clay adhered to the board.

This machine cannot perform well on clay
and other type of ground with a high water
percentage. Drying the ground is recom­mended to make the ground water percent­age appropriate for the machine to get good
compacting performance.

If you want to suspend the work, to return
quickly to the idle position the throttle lever.
(Fig.22)

Compaction sensor (Compas) is a system
that uses acceleration sensor to show real­time soil stiffness with LED (light-emitting
diode) lights based on the number of com­pactions done.
This compaction sensor improves efficiency
of compaction work because it can prevent
the area already properly compacted from
being compacted more than necessary and
to identify the area where more compaction
is needed. The sensor also has a function to
detect abnormality such as vibration trouble
(insufficient vibration frequency), ground
trouble (soft soil) and functional issues.
(Fig. 23)

NOTE

What is shown by the compaction
sensor (Compass) is not the absolute
value of the soil stiffness.
When using the sensor, always calculate
appropriate soil stiffness by conducting
plate load test and dynamic load test
(FWD), etc. to calibrate the LED lighting
level with the actual measurement value.

After the engine has started, warm up the
engine at low speed for 2 to 3 minutes. This
is especially important in cold weather.

Do not pull the starter knob all the length of
the rope.
After engine start, do not let the starter knob
off your hand, but return it slowly by holding it.
If you let the knob off at the position where it
is pulled, the rope retracts suddenly, leading
to breakage of the recoil starter and engine.
While the engine is running, never turn the
key switch to the “START” position.

During operation, pay sufficient attention to
dangerous objects, obstacles, in the direc­tion of your work and surrounding area.
While in operation, never touch the moving
parts and high temperature parts of the ma­chine.

If the throttle lever is opened suddenly, the
machine starts to operate. When you operate
the throttle lever slowly, it may cause failure
of the clutch causing the bad connection.
(Fig.20)

Use the back and forth movement direction
control lever to make the machine move
backward and forward. When the direction
control lever is pushed forward, the machine
moves forward, when pulled backward, the
machine moves backward.
At neutral, the machine vibrates staying at
the same location.(Fig.21)

If that happens, because you cannot expect
sufficient compaction, do ground improve­ment work before proceeding with the com­paction process. (Fig. 26)

Detection of vibration abnormality
During operation when appropriate vibration
frequency cannot be achieved because of
the specified engine revolution or the loos­ened drive belt, or when the vibration fre­quency is too high, it is indicated by the
flashing light. (Fig. 27)

Sensor wire disconnection
(Between acceleration sensor and sensor
panel)
If flashing of red LED and green LED alter­nates as shown in the figure, please check
the sensor wire because there is a possibil­ity that it is disconnected. (Fig. 28)

Power cable disconnection
(Between battery and sensor panel)
If there is no power even when the key
switch is turned on, please check because
there is a possibility that the power cable is
disconnected.

Function to detect abnormality

Normal compaction (during compacting)
Green LED lights up when the sensor finds
that the machine is in normal compaction
process. When the revolution goes up, and
compaction starts, the yellow LED ① lights
up, and as the compaction proceeds, the
number of the lighted LEDs increases from

②

to ⑧. After the LED light that was cali­brated with the measured soil stiffness
value lights up, the compaction process
completes. (Fig. 24)

Normal compaction (Compaction limit)
Compaction limit is reached when all the
yellow LEDs from ① to ⑧ have lit up and
the red LED lights up. At this point, this ma­chine cannot do any further compaction. If
higher soil stiffness value is required, please
use a machine of higher level. (Fig. 25)

Detection of ground trouble and soft ground
For a case of unstable ground or soft
ground (soil containing clay) for which the
use of this machine is not suitable, only the
red LED lights up, with no yellow LED illumi­nated.

Perform the first engine oil change after 20
hours of operation, then change at every
100 hours.(Fig.41)

The Engine Air Cleaner

When the air cleaner element becomes
dirty, the engine does not start smoothly,
and sufficient output cannot be obtained.
Machine operation will be affected and the
engine life will be shortened greatly. Do not
forget to clean the element. (For details,
please see the separate engine operation
manual.) If the element cannot be cleaned,
replace it with a new one.(Fig.42)

Cyclone Cleaner

Always clean Dust Pot. Clogged Dust Pot
leads to reduce cyclone effect with easy
wear of Cleaner Element.

11.4 Cleaning The Air Cleaner

11.5 Checking/Changing The V-belt
And Clutch

Clean Dust Pot inside with water and neu­tral detergent.

Latch up securely to return Dust Pot to Air
Cleaner.(Fig. 44)

Check of V-belt (Fig. 45)
At every 200 hours, remove the belt cover
(top) to check the tension of the V-belt.
The flexibility of the belt should be about
10 mm when pushed strongly with your
finger at the mid-point between the axes.
When the V-belt is loose, the engine
power is not transmitted well, resulting in
poor compacting force and shortening the
life of the V-belt.

Changing the V-belt

Removing the V-belt

Remove the top and bottom belt covers.
Put a wrench (19mm) on the tightening
bolt of the vibrator pulley (lower side). Put
a piece of cloth at the center of the left
side of the V-belt, and pull the belt strongly
towards you. While pulling, turn the
wrench clockwise, then remove the V-belt.

11.6 Checking/Changing The vibrator Oil

11.7 Checking/Changing The Hydraulic Oil

Installing the V-belt

Set the V-belt on the lower side of the vibra­tor pulley. Push the V-belt to the left side of
the upper clutch. Similar to removing the
V-belt, turn the wrench clockwise to install.

Stop the engine when inspecting or chang­ing the V belt.
Be careful not to have your hand or clothes
get caught between the V belt and the
clutch. Always wear work gloves.

At every 100 hours of operation, set the
machine on a level surface and remove the
oil gauge of the vibrator. Check the oil level
to see if it is within the allowable range.
(Fig.46)
Change the vibrator oil at every 300 hour
operation. Drain the oil from the drain plug.
For draining, put a beam under the com­pacting board at the other side of the drain
plug to tilt the machine.

Use engine oil SAE 10W-30 as lubrica­tion oil.The quantity used is 600cc.

Appropriate maintenance is required to
ensure safe and efficient operation of the
machine. Pay special attention to the parts
used for lifting, if they are not maintained
properly, it might result in a serious accident.
When checking the vibrator oil, clean the
oil port beforehand to prevent dust and
other foreign materials from falling into the
oil. Whenever there is an oil leakage from
the vibrator, check the oil level.
In case that oil is drained from Drain Plug,
some oil still remains in Oil Pan. So be
sure to check oil level correctly by Oil
Gauge after filling oil.
Do not fill oil with excessive volume
(600cc). It may cause the terrible fuel con­sumption and lower machine performance
as the result of engine overload.

Check the hydraulic oil

Check the hydraulic oil at every 100 hours’
operation. By making the handle bar verti­cal (done at the time of storage), remove
the breather plug at the top of the hydrau­lic hand pump to see if the hydraulic oil is
at the specified level (OIL LEVEL).
(Fig. 47)

Changing the hydraulic oil

Remove the plug cap of the hand pump.
Then remove the breather plug (with
24mm wrench) before removing the hy­draulic hose connected to the cylinder on
the vibrator side. Set the run lever to
reverse, then drain the hydraulic oil from
the pump.(Fig.47, 48)

After the oil is drained, attach the hydraulic
hose again to the cylinder on the vibrator
side. With the direction control lever at the
forward-most position, fix to the hook with
a rope to immobilize.
(Fig.48, 49)

11.8 Battery

How to remove the battery

Remove the stopper at the two locations
on the top portion of the rear cover to
open the rear cover.(Fig.51)

Loosen, but not remove, the M8 bolts (2
bolts) used for cyclone cleaner attach­ment. Take out the cyclone cleaner down­ward.(Fig.52)

Take off the nuts and remove the battery
holder. After tilting the battery backward,
disconnect the battery terminal. When
doing so, always disconnect the black ter­minal on the minus side first.

By holding the top surface handle, pull
upward to remove the battery from the
machine.(Fig.53)

If an old battery is used, even when the bat­tery checker is not lighted (indicating charging
level low), the cell starter might not operate
because of low charging level. If that hap­pens, change the battery with the new one.

Pay sufficient attention so that the battery ter­minal will not touch the frame.

Pour hydraulic oil(550cc) from the hand
pump breather plug attachment hole.
(Fig.47)

Remove the air releasing plug of vibrator
cylinder. Then oil will come out from the
air releasing plug. After air bubbles stop
coming out, attach the plug. Tighten se­curely. (Fig.48)

Then release the direction control lever
and move the lever forward and reverse
several dozen times (until air bubble not
be found). Stay the lever at the forward
position for 10 seconds every time.
(Because the check valve is opened at the
maximum forward position and air bubble
will come out from the oil tank of the hand
pump).(Fig.49)
In case the air bleeding is insufficient,
repeat the procedure of above “4” and “5”.

Attach the hand pump breather plug, put
on the plug cap. After making sure the hy­draulic oil in the pump is at OIL LEVEL,
attach the breather plug.

Hydraulic oil:
Shell Terrace Oil #32 or equivalent

Checking the battery

The standard battery installed is a mainte­nance free battery. It is not necessary to
supply battery fluid. In case of a sudden
voltage drop, the battery cannot be
charged quickly, so it has to be replaced
with a new one.

Check of battery capacity by battery
checker

When the battery charging level gets low,
the battery checker of the hour tachometer
lights up in red.(Fig.50)

The level of the hydraulic oil in the hand pump
should always be at OIL LEVEL. If the level is
higher, the oil bursts out from the breather plug.
