●Understand functions of operation control equipment and
familiarize yourself with where it is and how to control it.
Also, have a proper understanding of how to operate and
meaning of each symbol.
■Observe the rules in work site.
●Observe the established rules such as prohibitions in the work site, cautions, and work
procedures.
■Wear clothes suitable for the work, and protective means.
●Wear clothes suitable for the work, safety shoes, and safety cap.
●Do not wear clothes which are likely to be caught in a projection of the machine, and/or
an ornament. Also, do not wear a clothe stained with oil as it may catch fire easily.
●Never forget to wear protective goggles and a mask when required in the work.
■Handle with care when hot members are at high temperature.
●Take care not to be burned as the engine as a whole is very hot
during operation or immediately after it has been stopped.
●Do not allow your hand, body and clothe to be touched to
the muffler as it is very hot while the engine is running or
immediately after it has been stopped.

1. Basic safety precautions
■Pay attention to fire.
●Bringing a open flame close to fuel and oil may invite a fire.
In particular, fuel can catch fire very easily and it is dangerous.
●Do not bring a fire such as of cigarette or of match close to the
flammable materials.
●Supply fuel with the engine stopped after no fire has been
confirmed around the compactor.
●Tighten the caps such as for fuel and for oil securely.
■Pay attention to ventilation.
●Exhaust gas is harmful for your health. If the engine has to be
run in a room or in a poorly ventilated area, ventilate the area by
opening windows and/or entrances.
■Check the machine body before operation.
●Check to see if each part of the machine functions properly at a safe place. If it is found
anything wrong, be sure to take corrective measures to start operating the machine.
●Check the machine for unusual noise, unnatural vibration, heat and smell. If it is found
something wrong, stop the machine at a safe place immediately and check and locate the
cause to repair it.
■Be careful not to be caught in the machine.
●Do not stand close to the machine while operating the machine
because your hand, body, or clothe is likely to be caught in the
rotating members which may result in an injury.

3. Inspection before operation
3.1. Engine
Refer to a separate Engine Operation
Manual for the engine.
3.2. Checking engine oil
①Remove the oil gauge and wipe off oil
stuck on the gauge with a rag.
②Push the oil gauge against the oil fill port
without screwing it in to check oil level.
③Refill oil until it comes to the upper limit
mark when the level is insufficient.
3. Inspection before operation
Oil gauge
Fill port
Drain plug
Maximum oil level
Minimum oil level
(Refill is required)
Be sure to check and refill oil with the engine held level.
Check the oil level again at approx. 3 minutes after it has been refilled.
Do not supply oil more than the specified since over-supply of oil may
result in blowing out of oil and poor output of the engine.
Shortage of oil may cause seizure of the engine.
If an oil other than the specified is used, service life of engine is likely to
be shortened.

CAUTION
3.3. Checking oil in the vibrator
Remove the plug out of the fill-drain port
in the vibrator with the machine body held
level and check that the oil is filled up to the
mouth of oil fill-drain port.
If it is found insufficient, supply oil to the
extent that it comes full to mouth of the

WARNING
3.5. Checking bolts and nuts for their tightness
Bolts and nuts are likely to become loose due to vibration of the machine body.
If it is operated with the bolts and/or nuts loosened, lowering in function and damage to the
machine may result. Inspect the machine body to re-tighten any loosened bolts and nuts.
Oil leaks out of the bleeder in the vibrator if the machine is
left for a long period of time with the machine fallen down to
the right or to the left. Do not block the bleeder except when
it is necessary such as in carrying out a repair.
