Medium Duty (R10/06)
OPERATING THE ENGINE
Introduction
For detailed information on starting and operating the engine,
refer to the Engine Operation and Maintenance Manual pro-
vided with your Medium Duty.
Because each vehicle is custom-equipped, all engine opera-
tion instructions presented in this section are general. You
will want to consult the engine manual to find out details
about your vehicle's specific engine requirements. You may
need to use a slightly different procedure from the one out-
lined here.
Also, read the American Trucking Association's (ATA) Truck
Driver's Handbook. It will give you tips on starting, shifting,
and driving your vehicle.
WARNING! Do not use ether or other starting flu-
ids as a cold-starting aid in your Medium Duty.
Your engine uses either an electrical grid or an
open flame inside the manifold, to heat the air/
fuel mixture for cold weather starting. If ether or
another starting fluid is used, the air/fuel will
ignite inside the manifold, which could cause an
explosion and severe injury.
WARNING! Do not start or let the engine run in
an enclosed, unventilated area. Exhaust fumes
from the engine contain carbon monoxide, a col-
orless and odorless gas. Carbon monoxide can
be fatal if inhaled.
•Do not park or operate the vehicle in areas
where the hot exhaust system may come in con-
tact with dry grass, brush, spilled fuel or other
material that can cause a fire.
CAUTION: The use of a winterfront can result in
excessive engine coolant, oil, and charge air
(intake) temperatures, which can lead to over-
heating and possible engine damage. If you
must use a winterfront
Refer to the “Engine Operation and Mainte-
nance Manual” for operating restrictions
and recommendations.
Use only a winterfront available from your
Peterbilt dealer that is compatible with a
2002 EPA-compliant engine cooling system.
These winterfronts are specifically designed
for use with new grill snap patterns.
