<Cooling System - Bleed Air>
Bleed air sufficiently from the cooling
system.
* If air remains in the coolant, cooling
performance may decrease, and seizure of the
engine or piston scuffing may occur.
<Radiator Fins - Check and Clean
(Radiator Specification)>
When working by using compressed
air, wear protective glasses.
* Not wearing or not properly wearing personal
protective equipment may result in serious
personal injury.
Check the radiator fins for holes and
cracks.
* Otherwise, overheating, damage to the
devices, or performance degradation may
occur.
<Resin Fan Inspection
(Specifications with Resin Fan)>
Blade Inspection
Check that there are no flaws, cracks
or discoloration on the surface of
blades.
* If you operate the engine with a defective blade,
the blade may break.
Check that there is no play in the
blade mounting portion.
* If there is play in the blade mounting portion, the
blades may be abnormally worn.
Check that there is no looseness in
the blade mounting portion.
* If there is looseness in the blade mounting
portion, the blades may break.
Since replacing a blade requires
balancing, do not replace a single
blade by yourself.
* When replacing a single blade, be sure to ask
SME dealer.

Blade Cleaning
When cleaning the blades, do not use
acid and alkaline solutions.
* There is a risk of blade deterioration.
Do not use a high-pressure washer to
clean the blades.
* There is a risk of blade deterioration.
Before operating the engine, make
sure that the surfaces of blades have
dried.
* Operating the engine with the blades wet may
cause deterioration of the blade.
■ Intake and Exhaust Systems - Check
<Turbocharger - Check>
Before checking the turbocharger,
make sure that the engine has cooled
down to normal temperature. Before
checking, make sure that the
compressor wheel is not rotating.
* Otherwise, you could get burned.
* If you are caught in a rotating compressor
wheel, you will suffer laceration.
Make sure that there is no intake air
leak in the piping to the compressor of
the turbocharger.
* If there is intake air leak, insufficient boost
pressure could occur, which could cause
deterioration in the exhaust gas properties.
Check that the compressor or turbine
of the turbocharger is not dirty.
* If the compressor or turbine of the turbocharger
is dirty, performance degradation of the
turbocharger may occur, which could cause
power reduction.
