Engine Start and Operation
5
Turn the key on to the start position.
Release key as soon as the engine has
started. For the Volvo engine, the pre-
heater can be engaged to help starting
in cold temperatures. For switch func-
tion, see page 248.

CAUTION
If at start-up, or thereafter, the oil
pressure gauge indicates any drop
in oil pressure, the engine must be
shut down immediately. Failure to
stop the engine may cause major
engine damage.
When the engine has started, it takes a
while to send lubricating oil to all
bearings and shafts, and between pis-
tons and liners. Wait for the oil
pressure gauge to settle at a normal
level, then bring engine speed up grad-
ually. Increase speed as it warms up.
Check all gauges during warm-up.
7
During warm-up, apply load gradually
until the oil temperature reaches 140
F
(60
C). To start a loaded vehicle, the
minimum coolant temperature must be
approximately 120
F (50
C).
