Engine Operation
Page 37
engine is programmed to inject
sufficient fuel for starting.
Engine Warm Up
When the engine maintains a steady
oil pressure and the other systems
are functioning normally, the engine
is ready for operation.
If possible, avoid full throttle at the
start of operation until the engine
has reached an engine coolant
temperature of 140
°
F (60°C), or
until an appropriate period of time
has elapsed.
Operating the Engine
Exhaust gases, particularly carbon
monoxide, are potentially lethal.
Carbon monoxide is colourless and
odorless. If exhaust fumes are
present in the vehicle, report to
maintenance personnel
immediately.
Avoid idling the engine for
prolonged periods of time. Idling the
engine wastes fuel and may shorten
engine life. Deposits of unburned
fuel may form on the cylinder walls,
promoting unnecessary wear.
If idling is unavoidable, use the High
Idle feature.
High Idle
This feature increases engine idle
speed from the normal 800 rpm to
1,100 rpm.
The High Idle switch, located on the
side control panel, can be left in the
ON position during normal vehicle
operation.
The system operates when the High
Idle switch is in the ON position, the
parking brakes are applied, and the
gear selector is placed in the
NEUTRAL position.
Using the high idle feature is
recommended for pre-service for
the following reasons:
1. High oil pressure is maintained
in the engine to ensure correct
lubrication.
2. Cold weather affects battery
power. A high engine rpm
NOTE
If the engine does not start within
14 seconds, allow one minute for
the starter to cool, before the
next attempt.
NOTE
A safety feature in the starting
circuit prevents re-engagement
of the starter, while the engine is
running.
WARNING
Exhaust gases present in the
vehicle are potentially lethal. Do
not run the engine indoors,
unnecessarily.
