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.

GENERAL INFORMATION  
Definition of Tamping Rammer  
The Mikasa MT-75HS 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-75HS levels and uniformly compacts  
voids between soil particles to increase dry density.  
Circular motion is converted to create impact force. The MT-  
75HS 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-75HS is equipped with an Robin air cooled, oil-  
injected 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  
The Mikasa MT-75HS 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-75HS Tamping Rammer identify and  
understand the function of the controls, see Figure 1 on page11.

OPERATION  
This section is intended to assist the operator with the initial  
start-up of the MT-75HSTamping Rammer.It extremely important  
that this section be read carefully before attempting to operate  
the rammer.  
Engine  
1. Fill the fuel tank (Figure 3 ) with unleaded gasoline. At the  
same time, check the engine oil level at the sight gauge  
locatedontheoperator'ssideoftheoiltank. Filltheoiltank  
tothe"H"levelusingonlyoutboard(2-stroke)oil. Replenish  
theoilregularlybeforetheoillevelreachesthe"L"levelofthe  
oil tank.  
DO NOT use your rammer until this section is thoroughly  
understood.  
CAUTION:  
CAUTION:  
Failure to understand the operation of the MT-  
75HSTamping Rammer could result in severe  
damage to the trowel 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.  
Rammer Gearbox and Spring Cylinder Oil Bath  
This unit uses an oil bath lubrication system.Perform the following:  
1. Checktheoillevelthroughtheoillevelsightglass(Figure2)  
at the rear of the tamper foot.  
Figure 3. Fuel/Oil Tank  
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 .  
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(800cc.)
