OPERATION
2.5 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.
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.
2.6 To Stop
2.6.1 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.
2.6.2 Emergency shutdown
Move the throttle lever quickly to the IDLE position, and turn the engine ON/OFF switch
to the OFF position.
