(5) Abnormal Engine Noise

Pay attention to the noise from the engine or other related

parts, confirming normal operating noise.

(6) Check the Exhaust Color

Check exhaust color as listed in Section 6.3(2)3.

(7) Electrical System

Don't turn the key to the “OFF” position while engine is

under load or at full rpm. This may cause electrical parts dam-
age. See Section 6.5.  

6.5 Engine Stopping

1. Make sure that all of the control levers on the equipment

are in NEUTRAL position.

2. Before stopping the engine, cool down the engine by

operating it at low idle speed about three minutes.
With the engine at low idle, check the engine noise and
the engine oil pressure for abnormalities.
In the turbocharged engine, if the engine is stopped
instantaneously, a dry condition produced by high tem-
perature will take place in the turbocharger rotating parts
which may cause lack of lubrication.  This will result in
turbocharger failure.

3. Turn the starter key switch to the “OFF” position.  

CAUTION: 

Leaving the starter key switch in the

“RUN” position for a long period of time after the
engine has been stopped, will discharge the bat-
tery.

6.6 Run-In (Break-In) For New Engines

Your Shibaura engine is carefully tested and adjusted in

the factory, however, further, thorough run-in (i.e. break-in)
operation is necessary.

Operating a new engine under extreme loads and/or high

RPM’s, reduces lubrication, resulting in abnormal wear or
engine seizure. Avoid operating the engine under these condi-
tions for the first 100 hours. Observe the following proce-
dures on new engines:

1. Warm up the engine to operating temperature. During

this time do not race the engine.

2. Also do not operate the engine with rapid acceleration,

rapid machine starting and continuous high speed opera-
tion.

6.7 Engine Over-Cooling (Below Normal Operating
Temperature)

Engine over-cooling can cause premature wear and

increased fuel consumption.  When the coolant temperature
does not reach 75 to 90°C (167 to 194°F) indefinitely, par-
tially block the radiator to attain the proper operating temper-
ature.

6.8 Starting the Engine After Being Left Unused For
A Long Period of Time

When the equipment is left unused for "more than three

months" without running the engine, conduct a thorough
inspection of the vehicle before starting the engine.

After starting the engine, be sure to warm it up for more

than ten minutes at idling.

7. Periodic Inspection and Maintenance

7.1 LUBRICATING SYSTEM

Servicing of the engine oil or the oil filter element will

affect the engine performance as well as the engine life.

Change the engine oil and the oil filter element periodi-

cally with Shibaura or equivalent filter and oil of correct
grade and viscosity. (Refer to 5.2 Lubricant on page 9.)

(1) Engine Oil and Oil Filter Element Change

Always change the oil filter when changing the engine oil.

Follow the change schedule shown below.

Change interval

WARNING: 

To help avoid being burned, do not

drain oil while the engine is still hot.

1. Clean the area around the oil filler cap. Remove the filler

cap. 

2. Remove the oil pan drain plug and drain the engine oil

completely.
It is advisable that draining be done while the engine is
warm, to minimize the draining time.
