TR68 Operations Manual

To Start
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 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 slight resistance. Then pull
powerfully. 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.
5. 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.
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. With the ignition plug
removed,
pull the recoil starter handle 2-3 times to discharge excessive gas.

Operation
1. Turn the choke lever to open the choke. Run the engine for 5 minutes at low speed to
warm the engine.
2. Move the throttle lever quickly to the position. DO NOT move the
throt
tle lever 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.
CAUTION
3. 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 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 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.
