STARTING AND STOPPING PROCEDURE
4 - 9
Leaks
Inspect around vehicle and listen for any air leak.
Water separator
Purge drain valve (see page 6-5).
Turbocharger
Look for any leaks or unusual sounds coming
from the turbo compressor.
Service brakes
Check for pressure build-up. With engine
stopped and no brake applied, loss should not
exceed 3 psi/min (21 kPa/min). Make a full brake
application; loss should not exceed 7
psi
(48 kPa).
Parking and emergency brakes
With air pressure above 65 psi (450 kPa), lower
pressure with brake pedal applications, check
that buzzer works and that control button lifts up.
Wait until air pressure exceeds 95 psi (655 kPa)
before releasing parking brakes.
General Instructions
• Make sure the basic principles of operation of
the vehicle are understood.
• Do not drive your vehicle with an extremely
low fuel level. Unlike a gasoline engine, if a
diesel runs out of fuel it will not simply restart
after fuel is added to the tank. The engine
must be
primed
(see procedure in
Mainte-
nance Manual
).
• Allow engine to run at slow idle for at least 2
minutes before turning it off.
• Engine should always be at idle speed when
shifting from neutral to reverse or forward
range.
• Automatic transmission shift patterns does not
include a park position. Parking brake must
therefore be applied to hold vehicle when it is
unattended. Gearshift should then be in neu-
tral position. If engine is stopped without ap-
plying the parking brake, a warning buzzer will
sound until the parking brake is applied and
your foot is removed from the brake pedal.
• Perform procedures as detailed in this man-
ual.
• Unless otherwise specified, engine should be
turned off for all lubrication and maintenance
procedures.
• Do not attempt to push-start or pull-start the
vehicle.
• Do not tow vehicle without first removing the
drive axle shafts or disconnecting the drive
shaft. Internal lubrication of the automatic
transmission is inadequate when the vehicle is
towed.
• Fire extinguishers should be located in order
to be accessible at all times. In case of fire,
get everyone out of the vehicle, think of your
own safety before attempting to fight the fire.
• When driving on ice or snow, any acceleration
or deceleration should be done gradually.
Note:
Normal operation as well as some emer-
gencies or abnormal conditions are covered in
this booklet. Any malfunction interfering with sat-
isfactory operation should be corrected immedi-
ately, particularly when safety may be involved.
• The Gross Vehicle Weight Rating (G.V.W.R.),
and the Gross Axle Weight Ratings
(G.A.W.R.), for front, drive and tag axles of
your vehicle are listed on a metal certification
label affixed below L.H. side control panel in
driver's compartment. The G.V.W.R. is the
maximum load that can be applied on each
axle of the vehicle and is more than what is
legally permitted on some highways.
Do not exceed the G.V.W.R. and/or the
G.A.W.R., as it voids the Prévost warranty.
• Do not conceal the serial numbers and certifi-
cation plates (for location, refer to
Technical
Information
section). Reinstall in same loca-
tions after adding any trim.
• Installation of odd type and size of windows
may require cutting the vertical post of vehicle
structure. However, no more than three of
these posts should be cut on one side of a ve-
hicle and two adjacent posts should never be
cut.
Caution:
Violation of these instructions is not
safe and constitutes sufficient reason for Prévost
to void its warranty on any affected area.
