Definition of Tamping Rammer
The Mikasa MT-60HS 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 backfilling for gas pipelines, water pipelines and cable installation work.
The impact force of the MT-60HS levels and uniformly compacts voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MT­60HS 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-60HS is equipped with an Robin air cooled, oil­injected two cycle gasoline engine. Transmission of the power takes place by increasing the engine speed to engage the centrifugal clutch.
Rammer Gearbox and Spring Cylinder
GENERAL INFORMATION
The Mikasa MT-60HS 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-60HS Tamping Rammer identify and understand the function of the controls, see Figure 1 on page 11.

CAUTION:CAUTION:
Failure to understand the operation of the MT­60HS Tamping Rammer could result in severe damage to the trowel or personal injury.
Rammer Gearbox and Spring Cylinder Oil Bath
This unit uses an oil bath lubrication system. Perform the following:
1. Check the oil level through the oil level sight glass (Figure 2) at the rear of the tamper foot.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
Engine
1. Fill the fuel tank (Figure 3 ) with unleaded gasoline. At the same time, check the engine oil level at the sight gauge located on the operator's side of the oil tank. Fill the oil tank to the "H" level using only outboard (2-stroke) oil. Replenish the oil regularly before the oil level reaches the "L" level of the oil tank.
CAUTION:CAUTION:

CAUTION:CAUTION:
Failure to understand the operation of the MT­60HS Tamping Rammer could result in severe damage to the rammer or personal injury.
The oil hose is not to be depressed or damaged. A sensor detects lack of oil and shuts down the engine automatically.
Figure 2. Foot Housing Sight Glass
2. If oil is not visible, add 10W-30 motor oil into the oil fill plug opening (Figure 2). The bath contains approximately 1.7 pints (800 cc.)
NOTE
The oil level should be kept at the half way point of the sight glass.
MT-60HS PARTS & OPERATION MANUAL REV. #7 (03/02/01) PAGE 13
2. Low levels of oil may result in engine seizure due to high levels of consumption during operations.
3. Check the engine oil level (Figure 4) and if the oil level is low, it should be refilled. Use the proper motor oil as suggested in Table 3 .

Operation
1. To start the rammer tamping action, move the throttle lever (Figure 10) quickly from IDLE (close) to the FULL OPEN position . DO NOT move the throttle lever slowly as this may cause damage to the clutch or spring.
Stopping The Engine
Normal Shutdown
1. Move throttle lever quickly from the FULL OPEN to IDLE position (Figure 10) and run the engine for three minutes at low speed. After the engine switch to the OFF position (Figure 5) until engine comes to a complete stop.
2. Close the fuel shut- off valve by moving the fuel cock lever to the CLOSED position. See Figure 5

CAUTION:CAUTION:
Make sure that the throttle lever is moved to the FULL OPEN position (Figure 9). Operating the rammer at less than full speeds can result in damage to the clutch springs or foot
Figure 9. Throttle Lever
2. The MT-60HS Tamping rammer is designed to run at 5,500 rpm. At optimum rpm the foot hits at the rate of 675 impacts per minute. Increasing throttle speed past factory set rpm does not increase impacts and may damage unit. The MT­60HS is designed to advance while tamping. For faster advance, pull back slightly on the handle so that rear of foot contacts soil first.

Maintenance
Perform the scheduled maintenance procedures as indicated:
DAILY
Thoroughly remove dirt and oil from the engine and control area. Clean or replace the air cleaner elements as necessary. Check and retighten all fasteners as necessary. Check the spring box and bellows for oil leaks. Repair or replace as needed.
WEEKLY
Remove the fuel filter cap and clean the inside of the fuel tank.
Remove or clean the filter at the bottom of the tank.
Remove and clean the spark plug, then adjust the spark gap to 0.02~0.03 inch (0.6~0.7 mm). This unit has electronic ignition, which requires no adjustments.
Clean air cleaner cover.
200 - 300 HOURS (Pre-Cleaner)
Remove the element from the pre-cleaner (Figure 10) at the top of the crankcase (body side) and clean it with cleaning oil (kerosene).
The air cleaner on the engine side will hardly be contaminated, if it is, however after cleaning the element with kerosene, dip it in mixed oil consisting of 3 parts of gasoline and 1 part of engine oil. Then tightly squeeze outer primary element (sponge) and shake off well the inner secondary element before installing them.
CLEANING THE OIL TANK
Clean the inside of the oil tank regularly, preferably 2 or 3 times a year.
In winter, be sure to clean the inside of oil tank to avoid the freezing of water that may have accumulated inside the tank.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
When cleaning the oil tank (Figure 11) perform the following procedure:
MT-60HS MAINTENANCE
If water accidently got inside the oil tank, the oil may appear muddy. If this situation occurs, simply flush the tank, removing all foreign matter including water, and fill oil tank with fresh 2­stroke outboard motor oil.
PRE-CLEANER
GRAY 13 -15 CC SAE 30
Figure 10. Pre-Cleaner
Lubricate the top element (yellow) with 2~5 cc of engine oil SAE-30.
Lubricate bottom element (gray) with 13 ~15 cc of engine oil SAE-30 and completely squeeze out the excess oil from the element before installing.
YELLOW 2-5 CC SAE 30
1. Remove the cock holder cover, oil hose, red and black lead wires from the float sensor.
Figure 11. Oil Tank
PAGE 16 MT-60HS PARTS & OPERATION MANUAL REV. #7 (03/02/01)
MT-60HS MAINTENANCE
2. Remove the bolts that secure the oil tank to the fuel tank, and drain all oil from the tank.
3. Remove cock holder, then clean strainer and cock holder in a kerosene solution.
4. Make sure every part is clean and dry, then reassemble oil tank. Fill oil tank with 2-stroke outboard motor oil (FB class) to the "H" level.
FUEL AND OIL LINES
Check the fuel and oil lines regularly for damage and ensure that there are no leaks.
Replace fuel and oil lines every 2 years to maintain performance.
When replacing the oil hose perform the following procedure:
1. Replace oil hose with manufactures suggested type hose or equivalent.
2. If necessary, fill oil tank with 2-stroke outboard motor oil.
3. Fill fuel tank with 25:1 fuel mix ratio.
4. Operate rammer with 25:1 fuel mixture until all air is bled from oil injection line.
5. Once it is certain that all air has been purged from the oil injection line, regular unleaded gasoline may be used.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
It is normal for a new 2-stroke engine to emit excess smoke, until moving parts have been seated to their normal operating specifications. This excess smoke normally stops after one full tank of fuel.
CLEANING THE RAMMER
If using a high pressure spray washer, be careful not to splash water directly on the air cleaner, carburetor, muffler, fuel and oil tank caps. Excessive amounts of water may cause severe engine damage.
Yearly
Check the fuel line and the oil line regularly for damage and to ensure that there are no leaks.
Replace the oil and fuel lines every two years to maintain the performance and flexibility lines.
Long Term Storage
Drain fuel from fuel tank, fuel line and carburetor.
Remove spark plug and pour a few drops of motor oil into cylinder. Crank engine 3 to 4 times so that oil reaches all internal parts.
Clean exterior of rammer with an oil-moistened cloth.
Store unit covered with plastic sheet in moisture free and dust free location out of direct sunlight
200 - 300 HOURS (Oil Bath)
Drain oil reservoir on foot housing (Figure 13). Refill with approximately 1.7 pt. (800cc) of 10W-30 motor oil. Oil should be midway in sight glass. Break in oil should be changed after first 50 hours.
The air cleaner (Figure 12) on the engine side will hardly be contaminated, if it is, however after cleaning the element with kerosene, dip it in mixed oil consisting of 3 parts of gasoline and 1 part of engine oil. Then tightly squeeze outer primary element (sponge) and shake off well the inner secondary element before installing them.
