These devices are intended for operator safety. Disconnection of these devices can cause severe injury, bodily harm or even death. Disconnection of any of these devices will void all warranties.
DO NOT use this machine on ground that is harder than the machine can handle, or for driving pilings or tamping rock beds. Furthermore, use of the machine on sloping ground, such as the side of an embankment, may make the machine unstable and can cause an accident. It can also result in premature machine wear due to uneven loads on the machine.
Use the machine with confidence for tamping earth and sand, soil, gravel, and asphalt. DO NOT use the machine for other types of jobs.
CAUTION
NEVER lubricate components or attempt service on a running machine.
NOTICE
ALWAYS keep the machine in proper running condition.

ENGINE SAFETY
DANGER
The engine fuel exhaust gases contain poisonous carbon monoxide. This gas is colorless and odorless, and can cause death if inhaled.
The engine of this equipment requires an adequate free flow of cooling air.NEVER operate this equipment in any enclosed
or narrow area where free flow of the air is restricted. If the air flow is restricted it will cause injury to people and property and serious damage to the equipment or engine.
WARNING
DO NOT place hands or fingers inside engine compartment when engine is running.
NEVER operate the engine with heat shields or guards removed.
DO NOT remove the engine oil drain plug while the engine is hot. Hot oil will gush out of the oil tank and severely scald any persons in the general area of the rammer.

Definition of Tamping Rammer
The Mikasa MTX70 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 MTX70 levels and uniformly compacts voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MTX70 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 MTX70 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.
Rammer Gearbox and Spring Cylinder
The Mikasa MTX70 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 MTX70 Tamping Rammer identify and understand the function of the controls.
MTX70 — GENERAL INFORMATION
|
CAUTION |
Handle Operation |
|
|
|
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).

2.Units with Carburetor Primer System: Push the primer pump bulb four (4) times to deliver fuel to the carburetor (Figure 5-B).
MTX70 — OPERATION
DO NOT press the primer pump bulb more than four (4) times, as this will cause fuel to flood the carburetor.
3.Place the choke lever to the closed position. When the weather is cold, close the choke all the way.When it is hot, or if the engine is hot, open the choke a little or leave it fully open.
