Regional Haul Model Operator's Manual - Peterbilt Motors Company

STARTING PROCEDURE — NORMAL TEMPERATURES
• Use only a winterfront available from your
Peterbilt dealer that is compatible with a
EPA-compliant engine cooling system.
These winterfronts are specifically designed
for use with new grill snap patterns.
Starting Procedure — Normal Temperatures
Use the following procedure to start your Regional Haul
vehicle when outside temperatures are at or ABOVE normal
starting temperatures. Check the Engine Operation
and Maintenance Manual for starting temperatures.
1. Set the parking brake.
NOTE: When any one of the following is true, oil
should be applied to the turbocharger oil inlet
port: (1) if the engine has not been started for
more than 25 days; or (2), the outside temperature
is very cold; or (3), the oil filter has been
changed.
•With an oil can, squirt approximately one-half
cup (120 ml) of clean, specified engine oil into
the turbocharger oil inlet port. This will keep the
turbocharger bearings lubricated until the
engine oil pressure gets up to normal.
STARTING AND OPERATING THE VEHICLE
2. Insert key into the ignition switch.
3. Disable (or turn OFF) the following systems prior to
starting the engine: the exhaust brake, the dual-speed
rear axle (put in LOW), and block heater (if equipped).
4. Disengage the transmission: place the shift lever in
the Neutral position.
5. Disengage (depress) the clutch (with manual transmission).
6. Turn the ignition switch to the IGN & ACC position.
For normal temperatures, no accelerator advance is
necessary. See “Use of Accelerator” below. If the
“WAIT TO START” indicator lamp turns ON, wait until
the indicator lamp goes OFF (approximately 60 seconds)
before attempting to start the engine. (For each
engine and ambient temperatures, warm-up cycles
will vary.)
7. Turn the ignition switch to the IGN & START position
to engage the starter. Crank the engine until it starts.
If the engine does not start within 30 seconds, release
the key.
