1. Definition of Tamping Rammer
The Mikasa MT-86D diesel rammer is a powerful compacting
tool capable of applying tremendous force in consecutive
impacts to a soil surface. The impact force of the MT-86D levels
and uniformly compacts voids between soil particles to increase
dry density. Its applications include soil compacting for road,
embankment and reservoirs as well as backfilling for gas
pipelines, water pipelines and cable installation work.
2. Construction of Tamping Rammer
The rammer is equipped with an air-cooled, four-stroke diesel
engine. Transmission of the power takes place by increasing
engine speed to engage a centrifugal clutch. Circular motion is
converted into vertical motion to create impact force.
3-2. Preparation Inspection:
Rammer Gearbox and Spring Cylinder. This unit uses an oil
bath lubrication system. Check oil level through oil level sight
glass at rear of tamper foot. If oil is not visible, add #10W-30
motor oil. Oil bath contains approx. 1.7 pt. (800cc) for MT-86D.
3-3. Engine:
Use only automobile diesel fuel (Fig. 1). Check the engine oil
before starting operation and fill the oil regularly (Fig. 2). For
checking the oil level, move the engine to vertical position and
check that the oil is level with the oil inlet (about 700cc).
3-4. Check all nuts, bolts and fasteners for tightness. Retighten
as necessary.
3-5. Clean dirt from the recoil starter and foot. Wipe entire unit
clean before operating.
3-6. Replace any missing or damaged Safety/Operation decals.
