MTR-40HS — 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.

This Owner's Manual has been
developed to provide complete

NOTE

instructions for the safe and
efficient operation of the Multiquip
MTR-40HS Tamping Rammer.
Refer to the engine manufacturer's
instructions for data relative to its
safe operation.

Before using this Rammer,
ensure that the operating

individual has read and
understands all instructions in
this manual.

HAZARD SYMBOLS

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,
WARNING, or CAUTION.

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: You CAN be KILLED or

SERIOUSLY injured if you do not follow
directions.

CAUTION: You CAN be injured if you

do not follow directions.

Potential hazards associated with the MTR-40HS Tamping
Rammer operation 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.

Rotating Parts

NEVER operate equipment with covers, or

guards removed. Keep fingers, hands, hair and
clothing away from all moving parts to prevent
injury.

MTR-40HS — GENERAL INFORMATION

Definition of Tamping Rammer

The Mikasa MTR-40HS 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 MTR-40HS levels and uniformly
compacts voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MTR­40HS 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 MTR-40HS is equipped with a Robin air cooled, oil­injected 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 MTR-40HS 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 MTR-40HS Tamping Rammer identify and
understand the function of the controls, see Figure 1 on page 13.

replacement will allow
dirt to enter the engine,
causing rapid engine
wear.

Always check oil regularly.

Figure 3. Grip Handle

2. The rammer should be greased with three shots of grease
after each eight (8) hours of use.

3. Use MQ HIGH TEMPERATURE GREASE, P/N GRS2 or its
equivalent.

4. Equivalent greases include Shell Darina or Texaco
Thermatex, both of which have a bentone base and EP-2
rating.

5. If an inferior grease is used, it may become too thick or too thin
due to changes in temperature, and improper lubrication
could result.

2. The MT-40HS tamping rammer is designed to run at 4,100
rpm. At optimum rpm the foot hits at the rate of 600~690
impacts per minute. Increasing throttle speed past factory
set rpm does not increase impacts and may damage unit. The
MT-40HS is designed to advance while tamping. For faster
advance, pull back slightly on the handle so that rear of foot
contacts soil first.

MAINTENANCE

Perform the scheduled maintenance procedures as definded by
Table 3 (page 21) and below:

DAILY

■

Thoroughly remove dirt and oil from the engine compartment
and rammer. Clean or replace the air cleaner elements as
necessary. Check and retighten all fasteners as necessary.
Check the bellows for oil leaks. Repair or replace as needed.

200 - 300 HOURS (Pre-Cleaner)

■

Remove the element from the pre-cleaner (Figure 16) at the
top of the crankcase (body side) and clean it with cleaning oil
(kerosene).

■

Lubricate bottom element (gray) with 7~9 cc of engine oil
SAE-30 and completely squeeze out the excess oil from the
element before installing.

■

The air cleaner (Figure 17) on the engine side will hardly be
contaminated, if it is, clean the outer foam gray element with
cleaning solvent. Tightly squeeze outer foam element to
remove any excess solvent before reinstalling.

It is normal for a new 2-stroke engine to emit excess
smoke, until moving parts have been seated to
their normal operating specifications. This excess
smoke normally stops after one full tank of fuel.

Remove and clean the spark plug (Figure 19), then adjust
the spark gap to 0.024 ~0.028 inch (0.6~0.7 mm). This unit
has electronic ignition, which requires no adjustments.

Replace the oil and fuel lines every two years to maintain the
performance and flexibility lines.

Long Term Storage

■

Drain fuel from fuel tank, fuel line and carburetor.

■

Remove spark plug and pour a few drops of motor oil into
cylinder. Crank engine 3 to 4 times so that oil reaches all
