FOOT OPERATED CONTROLS 00022
BRAKE PEDAL
The coach is equipped with a dual braking
system. The front brakes operate from a
different air source than the drive and tag axle
brakes.
The dual braking system becomes a modulated
emergency system if a pressure drop occurs in
the primary brake system.
Service brakes are applied by depressing the
brake pedal. Braking increases with the amount
of pressure applied to the foot pedal. Refer to
Other Features chapter under Antilock Braking
System. When the brake pedal is depressed, the
brake lights turn ON automatically.
For safe and effective braking, the air system
pressure should reach at least 95 psi (655 kPa)
in both the primary and secondary circuits.
A warning light and an audible alert will sound
when the air pressure in either the primary or
secondary circuits drops below 66 psi (455 kPa).
If this occurs, stop the coach, determine the
cause of the pressure loss before proceeding.
The brake pedal can be used in conjunction with
the transmission retarder. Refer to
Transmission Output Retarder in this chapter.
Warning: Immediately report any brake
system problem to the nearest Prevost or
Prevost-approved service center, or to your
company.
Warning: Do not "fan" or "pump" the brake
pedal. This practice does not increase brake
system effectiveness but rather reduces system
air pressure thereby causing reduced braking
effectiveness.
Caution: "Riding" the brake by resting one's
foot on the brake pedal when not braking can
cause abnormally high brake temperature, can
damage and cause premature wear of brake
components and reduce brake effectiveness.
ACCELERATOR PEDAL
Controls engine RPM as needed.
Note: The accelerator pedal will not operate
when the front door is open.
Caution: Do not let the engine operate above
2,450 RPM.
STEERING WHEEL ADJUSTMENT UNLOCK
AIR VALVE
Push on the valve button with the left foot to
unlock the steering wheel for tilt and telescopic
adjustment.
Warning: Do not adjust the steering wheel
while the vehicle is moving. Loss of control could
result. Park the vehicle safely and apply parking
brake before adjusting the steering wheel.
SPICER MANUAL TRANSMISSION
The optional manual transmission has 6 or 7
forward gears (including creeper) and one
reverse gear.
