SAFETY INFORMATION

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.

CAUTION

FUEL SAFETY

DANGER

 DO NOT add fuel to equipment if it is placed inside truc

bed with plastic liner. Possibility exists of explosion or
fire due to static electricity.

 DO NOT

before servicing equipment.

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.

 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.

PAGE 8 — MT54F RAMMER — OPERATION AND PARTS MANUAL — REV. #8 (01/10/12)

 DO NOT fill the fuel tank while the engine is running

or hot.

 DO NOT overfill tank, since spilled fuel could ignite if it

Definition of Tamping Rammer

The Mikasa MT-54F 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 MT-54F levels and uniformly compacts
voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MT-54F
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-54F Tamping Rammer is equipped with an Robin
air cooled, four cycle gasoline engine. Transmission of the power
takes place by increasing the engine speed to engage the
centrifugal clutch.

Rammer Gearbox and Spring Cylinder

GENERAL INFORMATION

The Mikasa MT-54F 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-54F Tamping Rammer, identify and
understand the function of the controls, see Figure 1 on page 11.

downward.

5. Oil Bath Fill Plug – Open this plug to add oil to the oil
bath reservoir.

6. Drain Valve – Open this valve to remove oil from the
bellows.

7. Pre- Cleaner – Pre-cleans (first stage) dirt and other
debris from entering the engine.

8. Foot– Laminated wood with tempered steel plate for

superior shock absorption.

9. Oil Level Sight Glass – Indicates the level of oil in the oil
bath reservoir.

10. Recoil Starting Handle – Used when starting the engine.

BASIC ENGINE

Figure 1-A. Engine Controls and Components

INITIAL SERVICING

The engine (Figure 1-A) must be checked for proper lubrication and
filled with fuel prior to operation. Refer to the manufacturer's Engine
manual for instructions and 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.

Operating the engine without an

NOTE

air filter, with a damaged air filter,
or a filter in need of replacement
will allow dirt to enter the engine,

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.

CAUTION - Burn Hazard

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