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.
2.4.2 Start 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.
2.5 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.
