MT55-F — SAFETY MESSAGE ALERT SYMBOLS

FOR YOUR SAFETY AND THE SAFETY OF OTHERS!

Safety precautions should be followed at all times when operating
this equipment. Failure to read and understand the Safety
Messages and Operating Instructions could result in injury to
yourself and others.

HAZARD SYMBOLS

NOTE

This Owner's Manual has been developed to provide
complete instructions for the safe and efficient operations
of the MQ Mikasa MT55-F Tamping Rammer. Refer to
the engine manufacturers instructions for data relative
to its safe operation.

Before using this Tamping Rammer, ensure that the
operating individual has read and understands all
instructions in this manual.

SAFETY MESSAGE ALERT SYMBOLS

The three (3) Safety Messages shown below will inform you
about potential hazards that could injure you or others. The
Safety Messages specifically address the level of exposure to
the operator, and are preceded by one of three words: DANGER,

Lethal Exhaust Gases

Engine exhaust gases contain poisonous
carbon monoxide. This gas is colorless and

odorless, and can cause death if inhaled.
NEVER operate this equipment in a confined

area or enclosed structure that does not
provide ample free flow air.

Explosive Fuel

Gasoline is extremely flammable, and its
vapors can cause an explosion if ignited. DO
NOT start the engine near spilled fuel or
combustible fluids. 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. Store fuel in

approved containers, in well-ventilated areas
and away from sparks and flames. NEVER
use fuel as a cleaning agent.

DANGER: You WILL be KILLED or

SERIOUSLY injured if you do not follow
directions.

WARNING: Yo u CAN be KILLED or

SERIOUSLY injured if you do not follow
directions.

CAUTION: You CAN be injured if you

Potential hazards associated with operation of the rammer will
be referenced with Hazard Symbols which appear throughout
this manual, and will be referenced in conjunction with Safety
Message Alert Symbols.

Burn Hazards

Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas
while the engine is running or immediately after
operations. Never operate the engine with heat
shields or heat guards removed.

MT55-F — GENERAL INFORMATION

Definition of Tamping Rammer

The Mikasa MT55-F 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 MT55-F levels and uniformly
compacts voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The
MT55-F 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 MT55-F is equipped with an air cooled, 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 MT55-F 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 MT55-F Tamping Rammer identify and
understand the function of the controls, see Figure 1 on
page 13.

Figure 2. Engine Controls and Components

INITIAL SERVICING

The engine (Figure 2) must be checked for proper lubrication and
filled with fuel prior to operation. Refer to the manufacturers Engine
manual for instructions & details of operation and servicing.

1. Secondary Air Cleaner – Prevents dirt and other debris

from entering the fuel system. Remove wing-nut on top of
air filter cannister to gain access to filter element.

2. Choke Lever –Used when starting the engine. Normally

used in cold weather conditions. In cold weather turn the
choke lever to the fully closed position, in warm weather
set choke lever half way or completely open.

3. Spark Plug – Provides spark to the ignition system. Set

spark plug gap to 0.02 - 0.03 inch (0.6 - 0.7 mm). Clean
spark plug once a week.

4. Engine ON/OFF Switch – Controls the starting and

stopping of the engine. Switch must be in the "ON" position
when starting the engine.

NOTE

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.

5. Recoil Starter (pull rope) – Manual-starting method. Pull

the starter grip until resistance is felt, then pull briskly and
smoothly.

6. Muffler – Used to reduce noise and emissions.

while the engine is running or immediately after operating. NEVER
operate the engine with the muffler removed.

7. 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.

8. Oil Drain Plug – Remove this plug to remove oil from the

engine's crankcase.

WARNING

Engine components can generate extreme heat.
To prevent burns, DO NOT touch these areas

CAUTION:CAUTION:

Failure to understand the operation of the MT55­F 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 3)
at the rear of the tamper foot.

Fuel

1. Fill the fuel tank (Figure 4) with unleaded gasoline. DO NOT

overfill, wipe up spilled fuel immediately.

Engine Oil Check

1. To check the engine oil level, place the rammer on secure
level ground with the engine stopped.

Figure 4. Fuel Tank

2. Remove the filler cap/dipstick from the engine oil filler hole
(Figure 5) and wipe it clean.

Figure 3. Foot Housing Sight Glass

2. If oil is not visible, add 10W-30 SE, SF or higher grade motor
oil into the oil fill plug opening (Figure 3). The bath contains
approximately 1.0 pints (520 cc.)

NOTE

The oil level should be
kept at the half way
point of the sight glass.

3. Insert and remove the dipstick without screwing it into the filler
neck. Check the oil level shown on the dipstick.

4. If the oil level is low (Figure 6), fill to the edge of the oil filler
hole with the recommended oil type (Table 3). Maximum oil
capacity is .079 gallons (0.3 liters)
