The Mikasa MTR-35HS 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-35HS levels and uniformly
compacts voids between soil particles to increase dry density.
Circular motion is converted to create impact force. The MTR35HS 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-35HS 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
GENERAL INFORMATION
The Mikasa MTR-35HS uses an oil bath lubrication system.
Always check the oil level through the oil level sight glass at the
rear of the tamper foot.

This section is intended to assist the operator with the initial
start-up of the MTR-35HS Tamping Rammer. It is extremely
important that this section be read carefully before attempting to
operate the rammer.
DO NOT use your rammer until this section is thoroughly
understood.
Prior to starting the operation

1.Fill the fuel tank (Figure 3 ) with unleaded gasoline. At the
same time, check the engine oil level at the sight gauge
located on the operator's side of the oil tank. Fill the oil tank
to the "H" level using only outboard (2-stroke) oil. Replenish
the oil regularly before the oil level reaches the "L" level of the
oil tank.

CAUTION:
CAUTION:CAUTION:
Failure to understand the operation of the MTR35HS Tamping Rammer could result in severe
damage to the rammer 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.
Figure 2. 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, (part #GS 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.
6.The rammer is equipped with a two-cycled gasoline engine.
A regular grade gasoline should be used. High test ethyl
gasoline is not recommended. The oil should be good grade
of two- cycle or outboard motor oil.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
DO NOT USE REGULAR AUTOMOTIVETYPE MOTOR OIL.
2. Low levels of oil may result in engine seizure due to high
levels of consumption during operations.
3. Check the engine oil level and if the engine oil level is low, it
should be refilled. Use the proper motor oil as suggested in
1.Check all nuts, bolts fasteners for tightness. Retighten as
necessary.
2.Clean any dirt from the recoil starter and foot pedestal. Wipe
the entire unit clean before operating.
3.Replace any missing or damaged Safety Operation decals.
4.Adjust height of handle. Adjust handle by loosening nuts and
moving handle to suit operation. Retighten nuts.
Initial Start-up
When starting the MTR-35HS Tamping Rammer perform the
following:
3.Close the choke lever (Figure 4) . Turning the choke lever
90 degrees clockwise closes the choke . In cold weather, start
the unit with choke fully closed. In warm weather or when the
engine is warm, the unit can be started with choke halfway
or completely open.
4.Move the throttle lever (Figure 6) between 1/4 to 1/2 from the
idle position.

Perform the scheduled maintenance procedures as indicated:
DAILY
■
Thoroughly remove dirt and oil from the engine and control
area. Clean or replace the air cleaner elements as necessary.
Check and retighten all fasteners as necessary. Check the
spring box and bellows for oil leaks. Repair or replace as
needed.
WEEKLY
■
Remove the fuel filter cap and clean the inside of the fuel
tank.
■
Remove or clean the filter at the bottom of the tank.
■
Remove and clean the spark plug, then adjust the spark gap
to 0.02~0.03 inch (0.6~0.7 mm). This unit has electronic
ignition, which requires no adjustments.
■
Clean air cleaner cover.
200 - 300 HOURS (Pre-Cleaner)
■
Remove the element from the pre-cleaner (Figure 11) at the
top of the crankcase (body side) and clean it with cleaning oil
(kerosene).
The air cleaner on the engine side will hardly be contaminated,
if it is, however after cleaning the element with kerosene, dip
it in mixed oil consisting of 3 parts of gasoline and 1 part of
engine oil. Then tightly squeeze outer primary element
(sponge) and shake off well the inner secondary element
before installing them.
CLEANING THE OIL TANK
■
Clean the inside of the oil tank regularly, preferably 2 or 3 times
a year.
■
In winter, be sure to clean the inside of oil tank to avoid the
freezing of water that may have accumulated inside the tank.
CAUTION:CAUTION:

to the "H" level.
FUEL AND OIL LINES
■
Check the fuel and oil lines regularly for damage and ensure
that there are no leaks.
■
Replace fuel and oil lines every 2 years to maintain
performance.
■
When replacing the oil hose perform the following procedure:
1.Replace oil hose with manufactures suggested type hose or
equivalent.
2.If necessary, fill oil tank with 2-stroke outboard motor oil.
3.Fill fuel tank with 25:1 fuel mix ratio.
4.Operate rammer with 25:1 fuel mixture until all air is bled from
oil injection line.
CLEANING THE RAMMER
■
If using a high pressure spray washer, be careful not to splash
water directly on the air cleaner, carburetor, muffler, fuel and
oil tank caps. Excessive amounts of water may cause severe
engine damage.
Yearly
■
Check the fuel line and the oil line regularly for damage and
to ensure that there are no leaks.
■
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
internal parts.
■
Clean exterior of rammer with an oil-moistened cloth.
■
Store unit covered with plastic sheet in moisture free and
dust free location out of direct sunlight
5.Once it is certain that all air has been purged from the oil
injection line, regular unleaded gasoline may be used.
CAUTION:CAUTION:
CAUTION:
CAUTION:CAUTION:
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.
