Preface
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 engineering 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, our sales office, or the Mikasa Parts Service Center.
In addition, parts lists are available on the MIKASA website at:
http://www.mikasas.com/english/
The illustrations and the figures in this manual may be different from the machine
you actually purchased due to design changes and other reasons for improvement.
Application
Though compact and lightweight, this rammer creates a strong impact and you may expect a
large tamping effect on the ground.
It will compact nearly all types of soil, except soft soil that contains too much moisture.
Use this rammer to tamp the ground for creating roads, embankments, and to prepare the
surface to support buildings. It can also be used when burying gas or water lines, and electric
cables.
Warning about incorrect applications and techniques
Do not use this machine on ground that is harder than the machine can handle, or for driving
pilings or tamping rock beds. Furthermore, use of the machine on sloping ground such as the
side of an embankment, may be make the machine unstable and can cause an accident. It can
also result in premature machine wear due to uneven loads on the machine.
Use the machine with confidence for tamping earth and sand, soil, sand, gravel, and asphalt.
Do not use the machine for other type of jobs.
Structure
The upper section of the machine functions as a weight and consists of an engine section
guide, a gear reducer section, and reciprocating section. It also accommodates the handle and
the fuel tank sections, which are connected by rubber dampers.
The lower section of the machine which hits the ground, consists of a spring case to engage
sliding motion, a sloping section to allow the machine to tilt toward the front, bellows to cover
the foot, a sliding section, and a protective sleeve.
Power transmission
Power is provided by an air-cooled, 4-cycle, single-cylinder gasoline engine. The output end of
the engine crankshaft is equipped with a centrifugal clutch.
As the engine speed increases, the centrifugal clutch expands and a pinion gear that is a part
of the clutch drum engages a gear in the crank shaft on the main frame. The engine speed is
decreased in order to produce the required force for tamping.
The rotating motion of the main frame crankshaft is converted to a reciprocating motion through
a connecting rod. This reciprocating motion causes the foot to go up and down through a strong
coil spring. The weight of the main body and the strong force from the engine compress the
spring and the foot moves up and down, striking the ground forcefully.

Precautions for safety
General precautions
！！
WARNING
■
DO NOT work in the following conditions.
- 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.
！！
CAUTION
■
Read this instruction manual carefully
and handle the machine as described
so that you can work safely.
■
For details about the engine, refer the separate instruction manual for the engine.
Make sure you thoroughly understand the construction and operation of the machine.
■
T o w o r k s a f e ly , a l w a y s w e a r
protective clothing (helmet, safety
glasses, safety shoes, ear plugs etc.)
and appropriate work clothes.
Always check the machine to make
sure that it is normal before starting
operation.
■
The decals on the machine body (operating methods, warning decals, etc.) are very
important to ensure safety. Keep the machine body clean so that they can be read at all
times. If any decal cannot be read, replace it with a new one.
■
It is very dangerous if children come into contact with the machine. Take the utmost care
about how and where the machine is stored.
■
Before performing any maintenance, be sure to turn the engine off.
■
Mikasa does not accept any liability for accidents or problems caused as a result of not
using genuine Mikasa parts (foot assembly, etc.), or if the machine has been modified.

Precautions when adding fuel
！
DANGER
■
When adding fuel.
-
Be sure to work in a well ventilated location.
-
Be sure to turn the engine off and wait until it has cooled down.
-
Take the machine to a clear flat location without any combustibles nearby. Be careful not
any over fuel. If you do spill some gasoline, wipe it all up.
-
Do not allow any open flames nearby
while adding fuel. (In particular,
smoking while adding fuel is strictly
prohibited.)
■
Adding fuel until it comes too close to the top of the inlet may cause the fuel to overflow.
That is dangerous. Follow the instructions in the engine manual about the specified fuel
level.
■
When through adding fuel, tighten the tank cap securely.
Precautions about where to use the machine
！
DANGER
■
DO NOT run the engine in an
unventilated location, such as indoors
or in a tunnel. The exhaust gas from
the engine is carbon monoxide and is
deadly.
■
DO NOT operate the machine near
open fires.
Precautions before starting work
CAUTION
！
■
If you use the machine for a long time, be careful to watch for signs of vibration syndrome.
Since this machine vibrates, operation for a long time may have a negative effect on your
body. Take sufficient breaks while working.
■
Before starting to operate the machine, check for other people or obstacles that are too
close for safe operation.
■
When starting the engine, the rammer may jump suddenly. Hold the handle firmly with one
hand and pull the recoil starter with the other hand.
■
Always be careful around scaffolding. Operate the rammer in a stable manner so that it will
not become unbalanced.
■
During operation, don't let the foot of the machine come too close to your foot. The plate
may smash your foot.
■
The main parts of the engine, the
muffler, and muffler cover will be very
hot during operation. Be careful not to
touch them during operation or soon
after operation.
■
If you encounter any problems or abnormality with the machine during operation, while
moving it or stopping operation, stop work immediately.
■
Before leaving the machine, be sure to turn the engine off. Also, make sure to turn the
engine off if you want to move the machine. When the throttle lever is in the stop position,
the fuel cock is closed. Do not move the lever away from the stop position.
■
When lifting the machine by the handle, be careful not to pinch your fingers between the
handle and main body.
3
Precautions before starting work(Continued)
！
DANGER
■
Take the utmost care not to allow the
machine to fall during work, or when
stopped or stored. Secure the
machine with a rope or similar tie
when stored or left idle so that it
cannot fall. If the rammer falls over
when children are around, a serious
accident may occur. If the machine
foot is worn, the machine will be
especially unstable. If the machine
foot is worn badly, replace it with a
new one.
■
If the machine falls over while working, the machine will move forward due to the kicking
motion of the foot while it is lying on its side. If the ground is solid, it will move quickly and is
very dangerous. To ensure that the operator and anyone nearby are safe, turn the throttle
lever to the engine stop position and make sure the machine stops. You must be extremely
careful when working on a road because a serious accident can easily occur.
Precautions while lifting
！
DANGER
■
Before lifting the machine, make sure that there is no damage to any of the components on
the machine (look especially for damage to the rubber mounts and the hook). There must
not be any loose or missing screws and the machine must generally be in a safe condition.
■
Turn the engine off before lifting the machine.
■
Use wire cables with enough strength to support the machine.
■
DO NOT lift it higher than necessary, for safety.
■
DO NOTuse a damaged wire cable.
■
Only use the single hook to lift the
machine. DO NOT support it from any
other points (such as the handle).
■
Never lift or lower the machine rapidly when using a hydraulic shovel or a crane.
■
When lifting the machine, do not allow any people or animals to pass under or near the
machine.
■
When using any type of equipment to lift the machine, be careful that the lifting equipment
does not cause an accident. Make sure you check the lifting equipment carefully, to ensure
that there are no problems or damage.
