NOTE
Do not allow the engine to warm up at idle
speed. When under load, drive the truck at a

Switching off the engine
CAUTION
For engines with a turbocharger, the high speed
of the turbocharger shaft (approx. 100,000 rpmat
full load) could cause the shaft bearing to run dry
through lack of lubrication, thus damaging it.
Do not switch off the engine when under full load,
instead allow it to run on for a few minutes at low
speed.
