Chapter 3 OPERATION
Air Tank Air Pressure - Check
1. Check the air pressure gauge to see if the air pres-
sure in the air tank conforms to the standard.
2. Open the air pressure gauge valve.
3. Check air pressure in the air tank with air pressure
gauge.
Specified value:
For air direct starting: 2.94 MPa {30 kgf/cm
2
} [427
psi]
For air motor: 0.98 MPa {10 kgf/cm
2
} [142 psi]
4. Close the air pressure gauge valve.
Note: If the specification of air tank differs from the
contents of this operation manual, follow the
manufacturer's operation manual.

Damper temperature management by thermo label
It is recommended to use the thermo label for temper-
ature management of the damper. Check the thermo
label before starting engine.
1. Check the thermal part of thermo label is black.
2. Note the highest temperature of thermal part. Note
the temperature periodically, and check the abnor-
mality of temperature alteration.
Note: For damper temperature limit and inspection, re-
fer to "Damper - Inspect" (8-4).

(Display example)
When thermal part of the thermo label is
black until 80, it indicates that the maximum
temperature of damper during operating is
from 80°C [176°F] to 85°C [185°F].
