MTX70 — SAFETY INFORMATION  
ENGINE SAFETY  
DANGER  
FUEL SAFETY  
DANGER  
The engine fuel exhaust gases contain poisonous carbon  
monoxide. This gas is colorless and odorless, and can  
cause death if inhaled.  
DO NOT add fuel to equipment if it is placed inside truck  
bed with plastic liner. Possibility exists of explosion or  
fire due to static electricity.  
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 start the engine near spilled fuel or combustible  
fluids. Fuel is extremely flammable and its vapors can  
cause an explosion if ignited.  
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.  
ALWAYS refuel in a well-ventilated area, away from  
sparks and open flames.  
ALWAYS use extreme caution when working with  
flammable liquids.  
CAUTION  
NEVER touch the hot exhaust manifold,  
muffler or cylinder.Allow these parts to cool  
before servicing equipment.  
DO NOT fill the fuel tank while the engine is running  
or hot.  
DO NOT overfill tank, since spilled fuel could ignite if it  
comes into contact with hot engine parts or sparks from  
the ignition system.  
NOTICE  
NEVER run engine without an air filter or with a dirty air  
filter.Severe engine damage may occur.Service air filter  
frequently to prevent engine malfunction.  
Store fuel in appropriate containers, in well-ventilated  
areas and away from sparks and flames.  
NEVER tamper with the factory settings  
of the engine or engine governor. Damage  
to the engine or equipment can result  
if operating in speed ranges above the  
maximum allowable.  
NEVER use fuel as a cleaning agent.  
DO NOT smoke around or near the  
equipment. Fire or explosion could result  
from fuel vapors or if fuel is spilled on a  
hot engine.

MTX70 — SAFETY INFORMATION  
TRANSPORTING SAFETY  
CAUTION  
NEVER allow any person or animal to stand underneath  
the equipment while lifting.  
NOTICE  
Before lifting, make sure that the equipment parts (hook  
and vibration insulator) are not damaged and screws are  
not loose or missing.  
Always make sure crane or lifting device has been  
properly secured to the lifting bail (hook) of the  
equipment.  
ALWAYS shutdown engine before transporting.  
NEVER lift the equipment while the engine is running.  
Tighten fuel tank cap securely and close fuel cock to  
prevent fuel from spilling.  
Use adequate lifting cable (wire or rope) of sufficient  
strength.  
Use one point suspension hook and lift straight  
upwards.  
DO NOT lift machine to unnecessary heights.  
ALWAYS tie down equipment during transport by  
securing the equipment with rope.  
Never allow any person or animal to stand underneath the  
equipment while lifting.  
ENVIRONMENTAL SAFETY  
NOTICE  
Dispose of hazardous waste properly.  
Examples of potentially hazardous waste  
are used motor oil, fuel and fuel filters.  
DO NOT use food or plastic containers to dispose of  
hazardous waste.  
DO NOT pour waste, oil or fuel directly onto the ground,  
down a drain or into any water source.

MTX70 — GENERAL INFORMATION  
Definition of Tamping Rammer  
Handle Operation  
CAUTION  
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.  
Before starting operation check the lifting  
handle to:  
1. Make sure that there is no damage on the bolts.  
The impact force of the MTX70 levels and uniformly compacts  
voids between soil particles to increase dry density.  
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.  
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.  
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.  
Construction of Tamping Rammer  
1. Use proper lifting techniques to avoid back injury. This  
handle is for manual lifting only.  
The Mikasa MTX70 is equipped with an air cooled, four-  
cycle gasoline engine.Transmission of the power takes place  
by increasing the engine speed to engage the centrifugal  
clutch.  
2. Do not use this handle as a rammer lift point. Use the  
lifting point on the top of the machine.  
Rammer Gearbox and Spring Cylinder  
3. Do not move the rammer with the lifting handle and the  
front rollers more than 16 feet (5 meters).  
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.

Dipstick/Oil Filler Cap – Remove this cap to determine if  
the engine oil is low. Add oil through this filler port as  
recommended in Table 3.  
Operating the engine without an air filter, with a  
damaged air filter, or a filter in need of  
replacement will allow dirt to enter the engine,  
causing rapid engine wear.  
6.
