The Mikasa MT-86D tamping rammer is a powerful compactingtool capable of applying a tremendous force in consecutiveimpacts to a soil surface. Its applications include soil compactingfor road, embankments and reservoirs as well as backfilling forgas pipelines, water pipelines and cable installation work.
The impact force of the MT-86D levels and uniformly compactsvoids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MT-86Dtamping rammer develops a powerful compacting force at thefoot of the rammer. To maintain optimum performance, properoperation and service are essential.
Construction of Tamping Rammer
The Mikasa MT-86D Tamping Rammer is equipped with an Robinair cooled, four cycle gasoline engine. Transmission of the powertakes place by increasing the engine speed to engage thecentrifugal clutch.

The Mikasa MT-86D diesel rammer is a powerful compactingtool capable of applying tremendous force in consecutiveimpacts to a soil surface. The impact force of the MT-86D levelsand uniformly compacts voids between soil particles to increasedry density. Its applications include soil compacting for road,embankment and reservoirs as well as backfilling for gaspipelines, water pipelines and cable installation work.
2. Construction of Tamping Rammer
The rammer is equipped with an air-cooled, four-stroke dieselengine. Transmission of the power takes place by increasingengine speed to engage a centrifugal clutch. Circular motion isconverted into vertical motion to create impact force.
3-2. Preparation Inspection:
Rammer Gearbox and Spring Cylinder. This unit uses an oilbath lubrication system. Check oil level through oil level sightglass at rear of tamper foot. If oil is not visible, add #10W-30motor 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 oilbefore starting operation and fill the oil regularly (Fig. 2). Forchecking the oil level, move the engine to vertical position andcheck that the oil is level with the oil inlet (about 700cc).
3-4. Check all nuts, bolts and fasteners for tightness. Retightenas necessary.
3-5. Clean dirt from the recoil starter and foot. Wipe entire unitclean before operating.
3-6. Replace any missing or damaged Safety/Operation decals.
4-1. Move the throttle lever to IDLE position. (Fig. 3)
Throttle lever is used only at three (STOP, IDLE& OPERATION) positions. When moving thelever from stop to idle position, depress buttonon lever at same time it is moved.
In cold weather, the engine should be startedat operating position or between the idle andoperation position of the throttle lever. Usecaution as higher engine RPM may engageclutch, when engine starts. Return throttle leverfrom starting position to idle position whenengine starts.
4-2. Grip the recoil starter handle and pull it until you feel aslight resistance. (Fig. 4)
4-3. Press the decompression lever to release decompression.The decompression lever will return automatically when therecoil starter is pulled. (Fig. 5)
4-4. Return the recoil starter, and pull the handle sharply andquickly. Warm up the engine by running at low speed for threeto five minutes, while checking for fuel leakage or abnormalsounds.
Do not pull the starter rope all the way to theend and do not let the starter rope snap backas damage may result.
5-1. Move the throttle lever quickly from the IDLE to OPERATIONposition to start tamping action. DO NOT move the throttle leverslowly as this may cause damage to the clutch or spring box.
5-2. The tamping rammer is designed to tamp the ground 700times per minute at an engine speed of 3,300 rpm. Increasingthe engine speed above the recommended rpm will not increasethe rammer effectiveness. Impact will actually decrease becausea resonance is created rather than a tamping effect, and damageto the unit can result.
5-3. The rammer can be warmed by quickly moving the throttlelever from the OPERATION to the IDLE position several timesuntil the rammer operates smoothly.
5-4. The tamping rammer is designed to travel forward whiletamping. To increase travel speed, pull back slightly on thehandle so that the rear of the foot contacts the soil first.
5-5. To stop tamping, quickly move the throttle lever from theOPERATION to IDLE position. Do not move the lever slowly asirregular action and damage may result.
6. Stopping the Engine
6-1. Move throttle lever quickly from idle to STOP while pressingthe throttle lever button. Run the engine for three minutes at idlespeed to allow for proper cool down. Following the aboveprocedures will prevent improper cylinder lubrication causedby a overheated engine. (Fig. 6)
7. Service
