general Information

The Multiquip MTX60HD 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 MTX60HD levels and uniformly compacts voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MTX60HD tamping rammer develops a powerful compacting force at the foot of the rammer. To maintain optimum performance, proper operation and service are essential.

The MTX60HD 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.

The MTX60HD uses an oil bath lubrication system. Always check the oil level through the oil level sight glass at the rear of the tamper foot.

Before starting the MTX60HD Tamping Rammer identify and understand the function of the controls.

CAUTION

Before starting operation check the lifting handle to:

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).
