monoxide. This gas is colorless and odorless, and can  
cause death if inhaled.  
„ DO NOT add fuel to equipment if it is placed inside truck  
bed with plastic liner. Possibility exists of explosion or  
fire due to static electricity.  
„ The engine of this equipment  
requires an adequate free flow  
of cooling air.NEVER operate  
this equipment in any enclosed  
or narrow area where free flow  
of the air is restricted.If the air  
flow is restricted it will cause  
injury to people and property  
and serious damage to the

MTX70 — GENERAL INFORMATION  
Definition of Tamping Rammer  
Handle Operation  
CAUTION  
The Mikasa MTX70 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.  
Before starting operation check the lifting  
handle to:  
1. Make sure that there is no damage on the bolts.  
The impact force of the MTX70 levels and uniformly compacts  
voids between soil particles to increase dry density.  
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.  
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.  
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.  
Construction of Tamping Rammer  
1. Use proper lifting techniques to avoid back injury. This  
handle is for manual lifting only.  
The Mikasa MTX70 is equipped with an air cooled, four-  
cycle gasoline engine.Transmission of the power takes place  
by increasing the engine speed to engage the centrifugal  
clutch.  
2. Do not use this handle as a rammer lift point. Use the  
lifting point on the top of the machine.  
Rammer Gearbox and Spring Cylinder  
3. Do not move the rammer with the lifting handle and the  
front rollers more than 16 feet (5 meters).  
The Mikasa MTX70 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 MTX70 Tamping Rammer identify and  
understand the function of the controls.
