Definition of Tamping Rammer

The Mikasa MTR-60L 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.

NOTE

Narrow extension shoe accessories are available from MQ.

The impact force of the MTR-60L levels and uniformly compacts voids between soil particles to increase dry density.

Circular motion is converted to create impact force. The MTR60L 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

GENERAL INFORMATION

The Mikasa MTR-60L 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

The Mikasa MTR-60L uses an grease lubrication system. Always apply grease to all grease fittings every 8 hours of operation. (Shell Darina EP2 or Equivalent).

Controls

Before starting the MTR-60L Tamping Rammer, identify and understand the function of the controls, see Figure 1 on page 11.

MTR-60L — CONTROLS AND COMPONENTS

Figure 1. MTR-60L Tamping Rammer

Figure 1 shows the location of the controls and components for the MTR-60L Tamping Rammer. The functions of each control is described below:

1. Fuel Tank/Cap – Remove this cap to add fuel. Tank holds

.39 gallons (1.5 liters ) unleaded. Mix 32:1 ratio with outboard motor oil.

2. Throttle Lever – Controls engine speed and the tamping

action of the rammer.

3. Handle – To operate rammer

firmly.

4. Fuel Shut-Off Valve – Supplies fuel from the fuel tank to

the engine. To begin fuel flow move the fuel shut-off valve downward.

5. 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.

6. Engine Air Cleaner – Prevents dirt and other debris from entering the engine.

GRIP

handle assembly

8. Foot– Laminated wood with tempered steel plate for

superior shock absorption.

9. Fuel Valve – Open this valve to remove excess fuel from

the carburetor or crankcase.

10. Nameplate – Displays information regarding the rammer.

11. Muffler– Used to reduce noise and emissions.

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

Pull starter handle sharply and quickly, then return starter handle to starter case before releasing.

13. Engine Stop Switch – Controls the starting and stopping

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

14. Spark Plug – Provides spark to the ignition system,

replace with engine manufactures recommended type spark plug.

7. Grease Fill Plugs – Grease these plugs to lubricate the top and bottom mechanical component ends of the rammer.
