Definition of Tamping Rammer
The Mikasa MT-76D 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 MT-76D levels and uniformly compacts
voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MT-76D
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 MT-76D Tamping Rammer is equipped with an Robin
air cooled, four cycle gasoline engine. Transmission of the power
takes place by increasing the engine speed to engage the
centrifugal clutch.
Rammer Gearbox and Spring Cylinder
GENERAL INFORMATION
The Mikasa MT-76D uses an oil bath lubrication system. Always
check the oil level through the oil level sight glass at the rear of
the tamper foot.
Controls
Before starting the MT-76D Tamping Rammer, identify and
understand the function of the controls, see Figure 1 on page 11.

MT-76D — OPERATION
1. Definition of Tamping Rammer
The Mikasa MT-76D diesel rammer is a powerful compacting
tool capable of applying tremendous force in consecutive
impacts to a soil surface. The impact force of the MT-76D levels
and uniformly compacts voids between soil particles to increase
dry density. Its applications include soil compacting for road,
embankment and reservoirs as well as backfilling for gas
pipelines, water pipelines and cable installation work.
2. Construction of Tamping Rammer
The rammer is equipped with an air-cooled, four-stroke diesel
engine. Transmission of the power takes place by increasing
engine speed to engage a centrifugal clutch. Circular motion is
converted into vertical motion to create impact force.
3. Prior to Operation
3-1. Identification of Controls:
1. Throttle
2. Engine Lubrication Oil
3. Oil Fill Plug
4. Oil Level Sight Glass
5. Recoil Starter Handle
3-3. Engine:
Use only automobile diesel fuel (Fig. 1). Check the engine oil
before starting operation and fill the oil regularly (Fig. 2). For
checking the oil level, move the engine to vertical position and
check that the oil is level with the oil inlet (about 700cc).
3-4. Check all nuts, bolts and fasteners for tightness. Retighten
as necessary.
3-5. Clean dirt from the recoil starter and foot. Wipe entire unit
clean before operating.
3-6. Replace any missing or damaged Safety/Operation decals.
3-2. Preparation Inspection:
Rammer Gearbox and Spring Cylinder. This unit uses an oil
bath lubrication system. Check oil level through oil level sight
glass at rear of tamper foot. If oil is not visible, add #10W-30
motor oil. Oil bath contains approx. 1.7 pt. (800cc) for MT-76D.

4. Starting
4-1. Move the throttle lever to IDLE position. (Fig. 3)
MT-76D — OPERATION
Fig. 3
Throttle lever is used only at three (STOP, IDLE
& OPERATION) positions. When moving the
lever from stop to idle position, depress button
on lever at same time it is moved.
In cold weather, the engine should be started
at operating position or between the idle and
operation position of the throttle lever. Use
caution as higher engine RPM may engage
clutch, when engine starts. Return throttle lever
from starting position to idle position when
engine starts.
4-2. Grip the recoil starter handle and pull it until you feel a
slight resistance. (Fig. 4)
4-3. Press the decompression lever to release decompression.
The decompression lever will return automatically when the
recoil starter is pulled. (Fig. 5)
4-4. Return the recoil starter, and pull the handle sharply and
quickly. Warm up the engine by running at low speed for three
to five minutes, while checking for fuel leakage or abnormal
sounds.
Do not pull the starter rope all the way to the
end and do not let the starter rope snap back
as damage may result.

Fig. 5
MT-76D — PARTS & OPERATION MANUAL — REV. #6 (03/01/07) — PAGE 13
5. Operation
5-1. Move the throttle lever quickly from the IDLE to OPERATION
position to start tamping action. DO NOT move the throttle lever
slowly as this may cause damage to the clutch or spring box.
5-2. The tamping rammer is designed to tamp the ground 700
times per minute at an engine speed of 3,300 rpm. Increasing
the engine speed above the recommended rpm will not increase
the rammer effectiveness. Impact will actually decrease because
a resonance is created rather than a tamping effect, and damage
to the unit can result.
5-3. The rammer can be warmed by quickly moving the throttle
lever from the OPERATION to the IDLE position several times
until the rammer operates smoothly.
5-4. The tamping rammer is designed to travel forward while
tamping. To increase travel speed, pull back slightly on the
handle so that the rear of the foot contacts the soil first.
5-5. To stop tamping, quickly move the throttle lever from the
OPERATION to IDLE position. Do not move the lever slowly as
irregular action and damage may result.
MT-76D — OPERATION
Fig. 6
6. Stopping the Engine
6-1. Move throttle lever quickly from idle to STOP while pressing
the throttle lever button. Run the engine for three minutes at idle
speed to allow for proper cool down. Following the above
procedures will prevent improper cylinder lubrication caused
by a overheated engine. (Fig. 6)
7. Service
CAUTION:
Flammable Liquid: When refueling, stop engine and allow it
to cool.. Do no smoke or allow work to be
performed in the immediate area. Fire or
explosion could result from flames or sparks,
or if fuel is spilled on a hot engine.
Moving Parts: Shut down the engine before
performing service or maintenance functions.
Contact with moving parts can cause serious injury.
High Temperatures: Allow machine and engine to cool before
performing service or maintenance functions. Contact with hot
components can cause serious burns.
