Definition of Tamping Rammer
Tamping Rammer is a compacting machine, capable of quickly working by applying consecutive impacts to the surface of soil-in order to level the uneven soil surface, to compact the soil uniformly so that the void among soil particles are minimized and to increase its dry density with moisture in the soil removed.
Construction of Tamping Rammer
Air-cooled engine has bee installed as its source of power.
Transmission of the power is taken place by increasing engine speed to engage a centrifugal clutch, and the speed is substantially reduced by means of gears and rotational motion is converted into reciprocal
(vertical) motion.
A heavy duty spring is installed at the part that moves up and down so that its force and the weight of tamping rammer work each other to develop powerful compacting force at the foot of the rammer. Proper service and operation are essential for full commissioning of such performance.
Application
Rammers are designed to compact loose soils and gravel to prevent settling and to provide a firm, solid base for the placement of footings, concrete slabs, foundations, gas piping works, water pipe works and cable backfill works, etc.
Warnings for incorrect application and abuse
Please do not use in such as following cases. It may cause damage because machine is likely to be unbalanced.
Pile foundation
Hard soil excessively compacted over normal condition
Steep bank slope
Tamping Rammer is to be used for compacting cohesive clay, gravels, and patching work on asphalt, etc.

Prior to Starting the Operation
This machine is of oil bath lubrication system.
Check the oil level through a window at rear end of the foot. Replenish oil if oil is not visible at the window. For lubrication, use automobile engine oil of 10W-30 SE, SF or better grade. Capacity is
830cc.
Fill the fuel tank with regular gasoline (unleaded). Simultaneously, check engine oil and make it a habit to replenish on the earlier side. Low lubrication oil level may result in engine seizure due to
3
consumption during operation. Nevertheless, oil level should be checked prior to start up without fail.
For lubrication, use automobile engine oil of 10W-30 SE, SF or better grade. See Engine Operating
Manual for further detail.
Check every bolt, nut or screwed area for tightness. Loosened due to vibration may result in unexpectedly serious trouble. Be sure to tighten any screwed area.
Remove dirt and dust. Particularly clean the vicinity of recoil starter and foot.
Operation
Starting up for Petrol engine
1. Open the fuel shut-off valve by moving the fuel cock level to the open position.
2. Set the engine ON/OFF switch to the “ON” position.
3. Grip the recoil starter handle and pull it until you feel slight resistance. Then pull sharply and quickly.
Return the recoil starter handle to the starter case before releasing.
4. Grip the recoil starter handle and pull it a little to feel a slight resistance. Then pull it powerfully from there. To release the handle do not release it at the position where it has been pulled to, but release it after returning closely to the starter case.
5. If the engine has started, while listening to explosion sounds, return the choke lever slowly to full-open position. Be sure to perform a warm-up run for the period 3 to 5 minutes at low speed, while paying careful attention to gas leakage or abnormal sound.
6. If it is difficult to start the engine by repeatedly pulling the starter rope, remove ignition plug and check the sparking performance. If the plug is wet due to excessive fuel intake or soiled, replace the coil or clean sufficiently to its internals. With the ignition plug removed, pull the recoil starter handle 2-3 times to discharge excessive blended gas.
Starting up for machine
1. Turning the choke level to open the choke. Running the engine for 5 minutes at low speed to warm the engine.
2. Move the throttle level quickly to the “FULL OPEN” position. DO NOT move the throttle level slowly as this may cause damage to the clutch or spring.
Caution: Make sure that the throttle lever is moved to the FULL OPEN position. Operating the rammer at less than full speeds can result in damage to the clutch springs or foot.
3. After starting to tamping action, adjusts the jumping motion to suit particular soil condition by lightly controlling the throttle lever. When the engine speed falls between the set values shown on the engine, your work can be carried out at the best efficiently. Increasing the engine speed unnecessarily, does not cause the compaction force to increase. On the contrary, a resultant resonance causes the compaction force to decrease, damaging the machine.
4. Under cold weather, the oil in the machine being viscous, resistance at reciprocating part is greater causing the tamping rammer to perform somewhat irregular movement. Therefore, it is recommended to perform warm-up run while moving the throttle lever repeatedly between ON and OFF positions, before entering the work.
5. Soil contacting surface of the foot is lined with heat-treated metal sheet for extra strength. However, for compacting cobblestone, use the filling-up soil for example so that the foot hits the soil uniformly.
6. The tamping rammer has been designed to advance while jumping. For quicker advance, erect the machine by pushing its handle down slightly so that flat surface of the foot at its rear-end contacts the ground.
7. To stop the tamping action, move throttle lever quickly from the FULL OPEN to IDLE position.
4
To Stop
Normal shutdown
1. With the throttle lever closed from ON to OFF, run the engine for 3-5 minutes at low speed, and after temperature is lowered, turn the switch to the “OFF” position.
2. Close the fuel shut-off valve by moving the fuel cock lever to the CLOSED position.
Emergency shutdown
Move the throttle lever quickly to the IDLE position, and turn the engine ON/OFF switch to the OFF position.
