1. Preface
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: http://www.mikasas.com/ where you can access
Mikasa WEB parts lists.
This machine, weighing more than 60kg to more than 150kg, 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 guard frame. The
upper part of the machine is fixed to the compacting board of the lower part via an anti-vibration
rubber. The lower part of the machine consists of a compacting board and a vibrator. Inside the
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. A 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.
The illustrations in this manual might slightly differ in part from the machine you
actually purchased due to design changes.

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.

WARNING
！
DO NOT operate the machine,
- If you do not feel well due to overwork or illness.
- If you are taking any medicine.
- If you are under the influence of alcohol.
For details about the engine, refer the separate instruction manual for the engine.
Make sure you understand the structure of the machine well.
Always check the machine before your work to make sure it is in normal condition.ed.
Decals on the machine (operation method labels, warning labels, etc.) are very important for
your safety. Keep the machine clean so that the decals can be read all the time. Replace a
decal if it becomes illegible.
Before performing maintenance work, be sure to turn the engine off.
It is very dangerous if children come into close contact with the machine. Have the utmost
concern about how and where to store the machine. In particular, for an engine with a cell,
always remove the starter key and keep it in a designated place.
Before inspection and maintenance work, stop the engine, and do your work on a flat
surface area. If a cell is attached, remove the battery wiring before your work.
Mikasa does not accept any responsibility for accidents caused by remodeling or rework
done on the machine.

4-2. Refueling Precautions
DANGER
！
When adding fuel,
Do not fill to the rim due to potential spillage.
After adding the fuel, tightly close the tank cap
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.
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 unloading using a crane, a licensed crane operator is needed. An operator should be
qualified for crane and hooking work.
Before lifting, check the machine parts (especially the hook and anti-vibration rubber) for any
damage and loosened or missing bolts.
Take the machine to a clear flat location without any combustibles nearby.
Be careful not to spill the fuel. Wipe
well if any spill occurs.
