The illustrations in this manual might slightly differ in part from the machine you actually
purchased due to design changes.
This instruction manual describes the proper methods for using the tamping rammer, as well as simple checks and
maintenance. Be sure to read this instruction manual before using the rammer, in order to get full use of the excellent
performance of this machine, to improve your operation and to perform work effectively.
After reading this manual, store it in a handy location for easy reference.
For details about the engine in this machine, see the separate instruction manual for the engine.
For inquiries about repair parts, parts lists, service manuals, and repair of the machine, please contact the shop
where you purchased it, or the Mikasa Website. In addition, parts lists are available on the
MIKASA website at: http://www.mikasas.com/english/
This rammer is small size and lightweight, but it has strong impact force. Therefore, it will get the strong compaction
effect to the ground.
There is the strong compaction effect to the most soils except soft soil containing too much moisture.
Use the rammer to the construction works of roads, embankments and foundation works, and backfill works of gas
lines, water lines and other pipe lines.
Do not use the rammer for the pile driving work, and compacting work on the rock and hard ground that is over
compacted more than compaction ability of the rammer. Furthermore, in case of using the rammer on sloping ground
such as the side of embankments, it may cause an accident and machine trouble like an abnormal wear due to
unstable operation.
The upper section of the rammer that functioned as a weight consists of the engine section, gear reducer section,
reciprocating section. And handle and the fuel tank section are fitted to the upper section with shock absorber.
The lower section of the rammer that compact the ground consists of the spring cylinder section to generate sliding
motion, the sloping section to tilt machine forward, foot section to compact the ground, and bellows and protect
sleeve to cover the sliding section.
The rammer has the air-cooled, 4-cycle, single-cylinder diesel engine as power unit. And it is equipped the drive
shaft of engine with the centrifugal clutch.
With increasing engine speed, the centrifugal clutch expands and engages with the clutch drum integrated with the
pinion gear. The engine speed is reduced to the speed required for tamping by the reduction ratio of the pinion gear
and crank gear.
The rotary motion of crank gear is converted to the reciprocating motion through the connecting rod. This reciprocat-
ing motion generates jumping motion of the foot up and down through the strong coil spring of spring cylinder. The
rammer generates strong impact force to the ground by its own weight and the jumping motion of foot.
