Definition of Tamping Rammer

The Mikasa MT-62HS 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-62HS levels and uniformly compacts

voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MT-62HS

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-62HS 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-62HS 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-62HS Tamping Rammer identify and

understand the function of the controls, see Figure 1 on page 13.

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.

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 1.7 pints (800 cc.)

Engine Oil Check

1. This rammer is equipped with a two-cycled gasoline engine.

Use only unleaded gasoline. High test ethyl gasoline

is not

recommended.

2. Check the engine oil level at the sight gauge located on the

operator's side of the

oil tank

(Figure 5). 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.

3. Make sure the oil hose is not pinched or squeezed . A sensor

detects lack of oil and shuts down the engine automatically.

4. Remember low levels of engine oil may result in engine

seizure due to high levels of consumption during operation.

Always check oil regularly.

DO NOT USE REGULAR AUTOMOTIVE-TYPE

MOTOR OIL.

Figure 5. Oil Tank

The oil level should be kept at the

half way point of the sight glass.

Stopping The Engine

Normal Shutdown

1. Move throttle lever quickly from the FULL OPEN to IDLE

position (Figure 13 ) and run the engine for three minutes at

low speed.

2. The MT-62HS Tamping rammer is designed to run at 3,850

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-62HS is designed to advance while tamping. For faster

advance, pull back slightly on the handle so that rear of foot

contacts soil first.

Operation

1. To start the rammer tamping action, move the throttle lever

(Figure 12)

quickly

from IDLE (close) to the FULL OPEN

position. DO NOT move the throttle lever slowly as this may

cause damage to the clutch or spring.
