1．INTRODUCTION
2．MACHINERY OVERVIEW
This machine, weighing more than 200kg to more than 400kg, is a compactor with back and forth motion. The strong vibra-
tion 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 vibrat-
ing 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 incorpo-
rated 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.

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.

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.

Operation position
When this machine is used on ground that con-
tains 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 recom-
mended to make the ground water percent-
age 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.18)
When you move to the idle position the
throttle lever, please do not return to the oper-
ating position rapidly the throttle lever before
the rotational speed is possible fall.
CAUTION
！
8.2 Operation
During operation, pay sufficient attention to
dangerous objects, obstacles, in the direc-
tion of your work and surrounding area.
While in operation, never touch the moving
parts and high temperature parts of the ma-
chine.
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.16)
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.17)

mation with sufficient strength.
Slowly lift upward without applying any
impact. Never let people or animals go
under the lifted machine.
For safety reasons, do not lift to a height
that is higher than necessary.
Use a crane for loading and unloading the
machine.
Designate a person to guide the loading and
unloading, and always work under the
instruction of that person.
When lifting, always use a hook. (Fig. 22)
Never lift by using the hook on the handle.
Stop the engine when the machine is trans-
ported.
Always drain the fuel before transportation.
Fix the machine securely to prevent the ma-
chine from moving or falling.
When putting the handle into the stored
condition (vertical condition), make sure it is
