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.

2
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.
Structure
The upper part is made up of Power source, Clutch, Connecting Rod and Operating Handle, Fuel
Tank that connected via Shock Absorbing Rubber to body. Bottom end is made up of Spring Cylinder
(Sliding part), Foot Plate that ramps body, Foot and Bellows that covers sliding part.

Prior to Starting the Operation
 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. Low lubrication oil level may result in engine seizure due to consumption
during operation.
 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.
 Place rammer on loose soil or gravel. DO NOT start rammer on hard surfaces such as asphalt or
concrete.
Operation
To Start
1. Turn the fuel valve by moving the fuel cock level to the open position.
2. Press down the decompression lever. (When pulling the recoil starter rope, the
decompression lever will automatically return to initial position.)
3. Open the throttle control lever to the “start” position.
4. Grip the recoil starter handle，pull it until you feel slight resistance and return it slowly. Then
pull the recoil starter rope quickly.
5. If the engine does not start, repeat the start procedure from step 1.
6. 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 diesel leakage or abnormal sound..
To Stop
Switch off the engine as follows:
1. Reduce engine rpm‟s and let it run for a short while.
NOTICE: Do not switch off engine directly from full power.
2. Shut off the engine by moving the throttle control lever through the detent to the off position. The
engine will stop.
3. Close the fuel valve.
Caution: Do not switch off engine by means of the decompression lever.
Note: For short-term operation interruption, it is only necessary to stop the engine.
Operation
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

8
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.
