Do not touch the rotating part of the
alternator.
* Otherwise, you may get caught in the rotating
part and suffer an injury or damage to the
devices may occur.
When working by using compressed
air, wear protective glasses.
* Not wearing or wearing protective gears
incorrectly may result in serious injury.
Before draining or cleaning the
starting air strainer, bleed air
completely. In addition, check the
pressure reduction with the pressure
gauge.
* If high pressure air remains in the pipe, the
drain valve may blow off and cause personal
injury or damage to the devices.
Be sure to drain water from the
starting air tank.
* Otherwise, water may enter the cylinders when
starting the engine.
Make sure that the safety valve on the
starting air tank is not
malfunctioning.
* If the safety valve is out of order, improper
operation may occur and result in explosion of
the starting air tank.
Be sure to drain water from the
starting air tank.
* Otherwise, water may enter the air motor when
starting the engine.
Keep away from fire, when working
with flammable substances such as
volatile corrosion inhibitor or rust
preventive oil.
* They may cause a fire.
Keep away from fire, when working
with flammable substances such as
grease.
* They may cause a fire.
* When handling grease, obey the
manufacturer's SDS.
If the engine is stored for 3 month or
longer (up to 1 year), apply rust-
preventive measure properly.
* Otherwise, the internal engine parts and/or
sliding parts will rust, which may cause damage
to the devices.
* Follow the storage procedure described in this
Operation & Maintenance Manual.
Use volatile corrosion inhibitor and
rust preventive oil recommended by
us.
* If a product other than the recommendation is
used, the internal engine parts may be rusted
due to insufficient anti-rust effect.
Use new (immediately after opened)
desiccant.
* If you use a product which has been unused for
a long time since its package was opened,
moisture absorbency may be weakened, and
may cause the internal engine parts and/or
sliding parts to rust.
After stopping the engine, spray
volatile corrosion inhibitor while
cranking the engine for at least 2
times.
* Otherwise, accumulated and hardened anti-
corrosive agent on the piston may block turning.
