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/
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.
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.
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 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.
The illustrations and Figures in this manual may be different from the machine you
actually purchased due to design changes and other reasons for improvement.

DANGER
䟿
When adding fuel.
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.
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.
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.
Do not allow any open flames nearby
while adding fuel. (In particular,
smoking while adding fuel is strictly
prohibited.)

DANGER
䟿
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.
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.

DANGER
䟿
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.
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 dampers 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.
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.
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.
Only use the single hook to lift the
machine. DO NOT support it from any
other points (such as the handle).

䟿
When transporting
Before transporting the machine, stop the engine.
DO NOT try to move it before the engine and machine body have cooled down enough.
Drain any fuel before transporting the machine.
Transport the rammer in a manner that keeps it level. If you must lay the machine down to
transport it, drain any fuel from the fuel tank and carburetor. Then close the fuel tank cap
and oil fill plug securely. Next, position the machine so that the carburetor will be facing up.
Secure the machine body so that the machine cannot move or fall during transportation.
When you want to lift the machine by gripping the handle, be careful not to pinch your
fingers or hands between the handle and the main body.
Since this machine is quite heavy, use a truck specifically designed to transport heavy
objects.
When storing the machine
After the engine and machine body have cooled down enough, store the rammer so that it is
level. Fasten the machine as needed so that the machine cannot fall down. If it you must lay
the machine down, close the fuel tank cap and oil fill plug securely. Arrange the machine
position so that the carburetor will be facing up. After it is lying down, make sure there are
no oil or fuel leaks. (If fuel is leaking, drain it all from the fuel tank.)

This machine is of oil bath lubrication system.
Check the oil level through a window at rear end of the foot.
Replenish oil if oil is not visible at the window. For lubrication, use automobile
engine oil of 10W-30 SE,SF or better grade. Capacity is 520cc for MT-55/MT-55L,
750cc for MT-65H and 800cc for MT-72FW or the like. (Fig.1)
Fill the fuel tank with regular gasoline ( unleaded ). Simultaneously, check engine
oil and make it a habit to replenish on the earlier side. Low lubrication oil level
may result in engine seizure due to consumption during operation. (Fig.2 and
3-1,3-2) Nevertheless, oil level should be checked prior to start up without fail. For
lubrication, use automobile engine oil of 10W-30 SE,SF or better grade. See
Engine Operating Manual for further detail.
Check every bolt, nut or screwed area for tightness. Loosened due to vibration may
result in unexpectedly serious trouble. Be sure to tighten any screwed area.
Remove dirt and dust. Particularly clean the vicinity of recoil starter and foot.

Lower the fuel cock lever to let fuel flow. To start, switch must be in the "ON" position.
(Fig.4,5)
With carburetor choke lever closed, set throttle lever to CLOSE position. In cold
weather, it should be closed fully, while in summer season or if engine is warm, make
it half-open or full-open.
In case the engine failed to start, leaving the choke lever fully closed causes an
excessive fuel intake. Therefore it should be returned to the half-open position. (Fig.6)
Grip the recoil starter handle and pull it a little to feel a slight resistance. Then pull it
powerfully from there. To release the handle do not release it at the position where it
has been pulled to, but release it after returning closely to the starter case. (Fig.7)
If the engine has started, while listening to explosion sounds, return the choke lever
slowly to full-open position. Be sure to perform a warm-up run for the period 3 to 5
minutes at low speed while paying careful attention to gas leakage or abnormal sound.
If it is difficult to start the engine by repeatedly pulling the starter rope, remove
ignition plug and check the sparking performance. If the plug is wet due to excessive
fuel intake or soiled, replace the coil or clean sufficiently to its internals. With the
ignition plug removed, pull the recoil starter handle 2-3 times to discharge excessive
gas.

To start tamping action, move the throttle lever
(fig.8) quickly from CLOSE to the FULL OPEN
positon. Do not move the throttle lever slowly as
this may cause damage to the clutch or spring.
After starting tamping action, adjust the jumping
motion to suit particular soil condition by lightly
controlling the throttle lever. When the engine
speed falls between the set values shown on the
engine, your work can be carried out at the best
efficiency. Increasing the engine speed unneces-
sarily, does not cause the compaction force to in-
crease. On the contrary, a resultant resonance
causes the compaction force to decrease, damaging
the machine.
Under cold weather, the oil in the machine being viscous, resistance at reciprocating part
is greater causing the tamping rammer to perform somewhat irregular movement. Therefore,
it is recommended to perform warm up run while moving the throttle lever repeatedly
between ON and OFF positions, before entering the work.
Soil contacting surface of the foot is lined with heat-treated metal sheet for extra
strength. However, for compacting cobblestone, use the filling up soil for example so that the
foot hits the soil uniformly.
The tamping rammer has been designed to advance while jumping. For quicker advance,
erect the machine by pushing its handle down slightly so that flat surface of the foot at its
rear end contacts the ground.
To discontinue the work, contrary to the starting, move the throttle lever quickly from ON
to OFF.
The throttle lever should not be moved slowly.
With the throttle lever closed from ON to OFF, run the engine for 3- 5 minutes at low
speed, and after temperature is lowered, turn the switch to the "OFF" position. (Fig.9)

Remove dirt and dust from engine and control area. Clean air cleaner as necessary.
Check and retighten all fasteners as necessary.
Check spring box and bellows for oil leaks. Repair as needed.
Clean air cleaner cover. Adjust spark plug gap to 0.02-0.03 inch (0.6-0.7mm). This unit has
electronic ignition which requires no adjustments.
Remove fuel filter cap and clean. Clean every part of unit and retighten bolts and nuts as
necessary.
Drain oil reservoir on foot housing. Refill with approx. 520cc of #10W-30 motor oil for
MT-55/MT-55L, 750cc for MT-65H and 800cc for MT-72FW. Oil should be midway in sight
glass. Break in oil should be changed after first 50 hours. (Fig. 10 )
Remove element from pre-cleaner at the top of crank case and clean it with cleaning oil
(kerosene).
Take off `Bolt, Cover' of the crankcase upper part and take `Element' off `AIR CLENER'
(Fig.11, Fig12). Wet the bottom element (gray) with 7-9cc and let upper element (yellow) be
familiar with oil (MT-55/55L/65H).
MT-72FW is the top element (yellow) with 2 - 5cc and bottom element (gray) with 13 - 15cc of
engine oil SAE10W-30 squeeze out the oil before installing them. (Fig. 13) Air cleaner of the
engine side will hardly be contaminated, If it is, however, after cleaning the element with
kerosene, dip it in mixed oil consisting of 3 parts of gasoline and I part of engine oil. Them
tightly squeeze outer primary element (sponge) and shake off well the inner secondary
element before installing them. (Fig. 14, Fig. 15)
Rammer should be stored in such position as it is placed on level, after engine and machine
have been cooled down. Be sure to secure the rammer as necessary to avoid falling down. If
the rammer has to be laid down inevitably, tighten fuel tank cap and engine oil plug securely
and wait until engine and machine are cooled down. After laying it down, make sure that
there is no leak of fuel or oil. (If fuel leaks, drain the tank)
Long-term storage: Drain fuel from fuel tank, fuel line and carburetor. Remove spark plug
and pour a few drops of motor oil into cylinder. Crank engine 3 or 4 times so that oil reaches
all internal parts.
Clean exterior with a cloth soaked in clean oil store unit covered with plastic sheet in a
moisture free and dust free location out of direct sunlight.
