MT-74FA — OPERATION AND SAFETY DECALS

Machine Safety Decals

The MQ Mikasa tamping rammer is equipped with a number of safety decals. These decals are provided for operator safety and maintenance information. Figure 1 and 1A below and preceeding page illustrates these decals as they appear on the machine. Should any of these decals become unreadable, replacements can be obtained from your dealer.

MT-74FA — GENERAL INFORMATION

Definition of Tamping Rammer

The Mikasa MT-74FA 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.

CAUTIONCAUTION

CAUTION

CAUTIONCAUTION

Before starting operation check the lifting handle to:

Handle Operation

The impact force of the MT-74FA levels and uniformly compacts voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MT-74FA 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-74FA is equipped with an air-cooled, 4-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 MT-74FA 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-74FA Tamping Rammer, identify and understand the function of the controls. See Figure 2.

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.
