8. OPERATION AND CARE FOR
TURBOCHARGED ENGINE
(1) Engine Starting
The warming-up operation of the engine should be done in the way
separately described. In addition, ensure the bearings supporting the
rotating parts of the turbocharger are sufficiently lubricated.
1) Do not race cold engine.
2) When starting the engine after a long period (more than one month) of
standing, proceed as follows:
Pour engine oil into the turbocharger through the oil inlet port with the
air intake duct and oil inlet side pipe removed. Then turn the impeller
by hand to thoroughly lubricate the bearings.
3) When pouring oil in, do not allow dust particles and other foreign
materials to enter through the opening.
On completion of this operation, securely install the oil pipe and air
intake duct.
(2) Engine Stopping
Whenever stopping the engine, the last about 3 minutes of operation
should be at idle. After hard operation, at least 5 minutes of operation
should be at idle until the turbocharger cools down. This allows the
turbocharger to return to idle speed while engine oil pressure is
available for lubrication.
CAUTION:
Failure to cool down turbocharger at idle could result in
insufficient lubrication of its bearings and their shortened life.
