MT-60H/H2 — GENERAL INFORMATION
Definition of Tamping Rammer
The MQ Mikasa MT-60H/H2 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-60H/H2 levels and uniformly
compacts voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MT60H/H2 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 MQ Mikasa MT-60H/H2 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
The MQ Mikasa MT-60H/H2 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-60H/H2 Tamping Rammer, identify and
understand the function of the controls, see Figure 1.

bellows.
7. Pre- Cleaner – Pre-cleans (first stage) dirt and other
debris from entering the engine.
8. Foot– Laminated wood with tempered steel plate for
superior shock absorption.
9. Oil Level Sight Glass – Indicates the level of oil in the oil
bath reservoir.
10. Recoil Starting Handle – Used when starting the engine.
Pull starter handle sharply and quickly, then return
starter handle to starter case before releasing.
11. Fuel Tank/Cap – Poly fuel tank to avoid rust and
corrosion, remove this cap to add gasoline.

feel a slight resistance. Then pull sharply and quickly. Return
the recoil starter handle to the starter case before releasing.
Figure 8. Recoil Starter
5. When
the engine starts, move the choke lever slowly to the
"FULL OPEN" position. Warm up the engine by running at
low speed for three to five minutes, check for gas leakage or
abnormal sounds.
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, then move the choke lever
(Figure 7) to the half open position to avoid flooding and
repeat steps 1 thru 5.
Figure 6. On Off Switch
3. Close the choke lever Figure 7, and move the throttle lever
to the "Full Open" position. Turning the choke lever 90
degrees clockwise closes the choke . In cold weather, start the
unit with choke fully closed. In warm weather or when the
engine is warm, the unit can be started with choke halfway
or completely open.

3. To stop the tamping action, move throttle lever quickly from
the FULL OPEN to IDLE position.
Stopping The Engine
Normal Shutdown
1. Move throttle lever quickly from the FULL OPEN to IDLE
position (Figure 9) and run the engine for three minutes at

CAUTIONCAUTION
CAUTION
CAUTIONCAUTION
Make sure that the throttle lever is moved to the FULL OPEN
position. Operating the rammer at less than full speeds can
result in damage to the clutch springs or foot
2. The MT-60H/H2 Tamping rammer is designed to run at 5,500
rpm. At optimum rpm the foot hits at the rate of 675 impacts
per minute. Increasing throttle speed past factory set rpm
does not increase impacts and may damage unit. The MT60H/H2 is designed to advance while tamping. For faster
advance, pull back slightly on the handle so that rear of foot
contacts soil first.
