2) Raise up the rammer by raising the operation handle, and put the wheel kit (2) into the
hook on the base plate. Put down the rammer (Fig.03).
3) Tilt the rammer to make the wheel supporting on the ground. Hold the operation handle by
both hands and move rammer for a short distance (Fig.04).
WARNING
MUST remove the wheels before starting to use the rammer.
OPERATION
1. Application Scenarios
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.
DO NOT use in the following cases as it may cause damage because machine being
unbalanced.
● Pile foundation
● Hard soil excessively compacted over normal condition
● Steep bank slope
The Tamping Rammer is to be used for compacting cohesive clay, gravels, and patching work
on asphalt, etc.

2. Before Starting
● This machine is oil bath lubrication system. MUST fill the oil in the gear system before first
starting.
● For lubrication, use automobile engine oil of SJ or SAE 10W-30, or better grade.
● Open the plug at top of gear box. Fill the oil from it (Fig.05).
● Check the oil level through a window at rear end of the foot. Once the oil level reaches the
middle of window, and then stop filling (Fig.06).
● Replenish oil if oil is not visible at the window.
● 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 consumption during operation. Nevertheless, oil level should be
checked prior to start up without fail. For lubrication, use automobile engine oil of SAE
10W-30, or better grade. See Engine Operating Manual for further detail.
● Check every bolt, nut or screwed area for tightness. These may have become loosened
due to vibrations from previous use.
● Remove dirt and dust. Particularly clean the vicinity of recoil starter and foot.
3. Start Rammer
● Open the fuel shut-off valve by moving the fuel cock level to the open position.
● Set the engine ON/OFF switch to the “ON” position.
● 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.
● Grip the recoil starter handle and pull it a little to feel slight resistance. Then pull powerful
ly. To release the handle, do not release at the position where it has been pulled to, but
release after returning closely to the starter case.
● If the engine has started, return the choke lever slowly to the full-open position. Be sure to
perform a warm-up run for a period 3 to 5 minutes at low speed, while paying careful
attention to gas leakage or abnormal sound.
EN 6

Fig. 06

● 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. With the ignition plug removed, pull the recoil
starter handle 2-3 times to discharge excessive gas.
4. Operate Rammer
● Turn the choke lever to open the choke. Run the engine for 5 minutes at low speed to
warm the engine.
● Move the throttle lever quickly to the “FULL OPEN” position. DO NOT move the throttle
lever 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.
● After starting the tamping action, adjust the jumping motion to suit the 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 efficiency.
Increasing the engine speed does not cause the compaction force to increase. On the
contrary, a resultant resonance causes the compaction force to decrease, damaging the
machine.
● Under cold weather, the oil in the machine may become viscous, causing the tamping
rammer to perform somewhat irregular movement. It is recommended to perform a
warm-up run while moving the throttle lever repeatedly between ON and OFF positions,
before beginning to work.
● 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.
● 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.
● To stop the tamping action, move throttle lever quickly from the FULL OPEN to IDLE
position.
5. Stop Rammer
1) Normal Shutdown
● With the throttle lever closed from ON to OFF, run the engine for 3-5 minutes at low
speed, and after the temperature is lowered, turn the switch to the “OFF” position.
● Close the fuel shut-off valve by moving the fuel cock lever to the CLOSED position.
2) Emergency Shutdown
● Move the throttle lever quickly to the IDLE position, and turn the engine’s ON/OFF
switch to the OFF position.

MAINTENANCE AND STORAGE
1. Maintenance
* It’s better that changing ramming system oil after first 3 days of use.
Note: If engine performance is poor, check, clean, and replace air filter elements as needed.
2. Transportation
● Shut down engine for transportation.
● For transportation, tighten fuel tank cap securely and close fuel cock to prevent fuel from
spilling.
● Drain fuel for transportation over long distances or poor roads.
● Secure machine firmly to prevent it from moving or tipping.
● When lifting rammer, make sure lifting device has enough capacity to hold machine (see
identification plate on machine for weight). Use central lifting bar (A) when lifting
machine (Fig.07).
● The rammer should be transported in the same position as if it is placed on level ground.
In case the rammer must be laid down for transportation, drain the fuel tank as well as the
carburetor and make sure that the oil plug is tightened securely, then tie the rammer to the
vehicle at roller (B). It will help to move the rammer easily when lay down.

3. Storage
The rammer should be stored on level ground, a er the engine and machine have cooled
down. Be sure to secure the rammer as necessary to avoid it from falling. If the rammer has
to be laid down, tighten fuel tank cap and engine oil plug securely and wait until the engine
and machine are cooled down. After laying it down, make sure that there is no fuel or oil leak
(if fuel leaks, drain the tank).
3.1 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 with a cloth soaked in clean oil.
● Store unit covered with plastic sheet in moisture free and dust free location out of
direct sunlight.
