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.
