Caution
Be sure to follow the instructions on "(1)
Starting" after oil and oil filter are changed or
in winter where oil viscosity becomes
higher, or the engine is left unattended over
prolonged time(1 week or more). (However,
limit the starting key working time to 10
seconds or less, and perform re-starting
operation, if needed, in about 30 seconds
from the initial operation.

5-123 MISCELLANEOUS CONTROLS AND OPTIONS
1) Basic rules of operation
When the turbine blades installed at exhaust gas
outlet are rotated at high speed by the high pres-
sure and heat energy of exhaust gas discharged
after combustion in the engine, the compressor
blades connected integrally with the turbine shaft
start rotating at the same speed, so that an ample
amount of fresh air flows into the engine cylinder. A
sufficient supply of fresh air enables complete
combustion, resulting in decrease in fuel
consumption and increase in output.
2) Type of turbo charger
Type
TBP45 (Allied signal)
TB4122 (Allied signal)
TV45 (Garrett brand)
3) Tips for vehicle operation
As the turbo charger rotates at high speed, failure
to replenish engine oil within scheduled period or
lack of engine oil may cause damage to bearings,
etc.
Be sure to observe how to start and the operation
instructions before or after operation.
(1) Starting
Start the engine and check if the engine oil pres-
sure warning lamp is turned on and then go out.
Also, check if engine oil pressure is normal
when idling the engine.
After starting the engine, revolve the engine at
low speed(600~650 rpm) for about 1 minute,
increase the idle speed to approximately
900~1000 rpm to achieve further engine
revolution for 3~4 minutes, then drive off the
vehicle.
