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.

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.

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

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.)
