Engine Operating Range
Information on operating the engine at
proper rpm.
Proper Engine Operating Range
1. Full Throttle rpm
2. Peak Torque
CAUTION
Operating the engine at full throttle be-
low peak torque will shorten engine life
to overhaul, can cause serious engine
damage, and is considered engine
abuse. DO NOT operate the engine at
full throttle operation below peak tor-
que rpm for more than 30 seconds.
Failure to comply may result in equip-
ment or property damage.
PACCAR engines are designed to operate
at full throttle under momentary conditions
down to peak torque engine speed. This is
consistent with recommended operating
practices.
CAUTION
Operating the engine beyond the max-
imum engine speed can cause severe
engine damage. Use proper operating
techniques for the vehicle to prevent
engine overspeed. See Engine Speci-
fications for maximum engine speed.
Failure to comply may result in equip-
ment or property damage.
Extended Idling
CAUTION
Prolonged periods of idling can result
in lower than optimal engine/transmis-
sion operating temperatures which
could cause increased rates of wear.
An idle shutdown feature (available on
PACCAR engines) can be program-
med to shut the engine down after a
period of low idle operation with no
driver activity. A flashing warning lamp
will inform the driver of an impending
shutdown. Failure to comply may re-
sult in equipment or property damage.
CAUTION
If the truck is equipped with power
take off (PTO) equipment, the engine
shutdown system can be deactivated
when the PTO is operational; however,
engine idle periods should not exceed
five minutes whenever possible. Fail-
ure to comply may result in equipment
or property damage.
Long periods of idle-time (3 hours or more)
may accelerate the build up of soot in the
diesel particulate filter (DPF), especially in
cold weather. The system will illuminate the
DPF warning light on the instrument cluster
and a message on the Driver Information
Display to indicate that the DPF requires
