MTX-70 — GENERAL INFORMATION
Definition of Tamping Rammer
The Mikasa MTX-70 tamping rammer is a powerful
compacting tool capable of applying a tremendous force in
consecutive impacts to a soil surface. Its applications include
soil compacting for road, embankments and reservoirs as
well as backfilling for gas pipelines, water pipelines and cable
installation work.
The impact force of the MTX-70 levels and uniformly
compacts voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MTX70 tamping rammer develops a powerful compacting force at
the foot of the rammer. To maintain optimum performance,
proper operation and service are essential.
Construction of Tamping Rammer
The Mikasa MTX-70 is equipped with an air cooled, fourcycle gasoline engine. Transmission of the power takes place
by increasing the engine speed to engage the centrifugal
clutch.
Rammer Gearbox and Spring Cylinder
The Mikasa MTX-70 uses an oil bath lubrication system.
Always check the oil level through the oil level sight glass at
the rear of the tamper foot.
1. Make sure that there is no damage on the bolts.
2. Make sure that there is no crack or breakage on handle.
3. Make sure that there is no fissure on the surface. If there
is any abnormality or damage, replace with new one.
For operation:
This handle is to be used to lift up the shoe part of the machine
with the body laid down on the ground or truck bed.
1. Use proper lifting techniques to avoid back injury. This
handle is for manual lifting only.
2. Do not use this handle as a rammer lift point. Use the
lifting point on the top of the machine.
3. Do not move the rammer with the lifting handle and the
front rollers more than 16 feet (5 meters).

INITIAL SERVICING
The engine (Figure 1A) must be checked for proper lubrication and
filled with fuel prior to operation. Refer to the manufacturers Engine
manual for instructions & details of operation and servicing.
1. Choke Lever –Used when starting the engine. Normally
used in cold weather conditions. In cold weather turn the
choke lever to the fully closed position, in warm weather
set choke lever half way or completely open.
2. Spark Plug – Provides spark to the ignition system. Set
spark plug gap to 0.024 - 0.028 inch (0.6 - 0.7 mm). Clean
spark plug once a week.
3. Recoil Starter (pull rope) – Manual-starting method. Pull
the starter grip until resistance is felt, then pull briskly and
smoothly.
Operating the engine without an air filter, with a
damaged air filter, or a filter in need of
replacement will allow dirt to enter the engine,
causing rapid engine wear.
4. Muffler – Used to reduce noise and emissions.
while the engine is running or immediately after operating. NEVER
operate the engine with the muffler removed.
5. Dipstick/Oil Filler Cap – Remove this cap to determine if
the engine oil is low. Add oil through this filler port as
recommended in Table 3.
6. Oil Drain Plug – Remove this plug to remove oil from the
engine's crankcase.
WARNING
Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas

3. Grip the starter rope handle (Figure 7 handle and pull it until
you feel a slight resistance. Then pull sharply and quickly.
Return the handle to the starter case before releasing.
4. If engine fails to start, move the choke lever (Figure 6) to the
half open position to avoid flooding.
5. Repeat steps 1 thru 4.
6. If the engine does not start after repeated attempts,
check the spark plug for excess fuel. Clean and replace
the spark plug as needed.

590 ~ 695 impacts per minute. Increasing throttle speed past
factory set rpm does not increase impacts and may damage
unit. The MTX-70 is designed to advance while tamping. For
faster advance, pull back slightly on the handle so that rear
