GENERAL INFORMATION

Definition of Tamping Rammer

The Mikasa MTX80/MTX90 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 MTX80/MTX90 levels and uniformly
compacts voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The
MTX80/MTX90 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 MTX80/MTX90 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.

Rammer Gearbox and Spring Cylinder

The Mikasa MTX80/MTX90 uses an oil bath lubrication
system. Always check the oil level through the oil level sight
glass at the rear of the tamper foot.

Handle Operation

CAUTION

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).
