Foot-Operated Controls; Service Brakes - PREVOST H3-41 Manual

Caution
: To avoid damaging the pump
mechanism, do not use the windshield washer
when the fluid level is low.
Lower Windshield Wipers
Turn the lever counterclockwise to activate the
lower windshield washers. The first position
activates the wipers intermittently. The second
position is the slow speed and the third position
is for high speed wiping.
Caution
: To avoid scratching the windshield,
do not operate the wipers when the windshield
is dry. To avoid damaging the wiper motor,
loosen wiper blades that may be frozen to the
windshield before operating the wipers.
Electric Horn
The electric horn buttons are on the steering
wheel spokes. Use only the electric horn in
urban areas.
STEERING WHEEL
Air Horn
The air horn button is located on the center of
the steering wheel. Use this horn only on the
highway.
CONTROLS & INSTRUMENTS

FOOT-OPERATED CONTROLS

FOOT OPERATED CONTROLS

Service Brakes

The coach is equipped with a dual braking
system. The front brakes operate differently from
the drive and tag brakes.
The dual braking system becomes a modulated
emergency system if a pressure drop occurs in
the rear 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 "ABS Brake
(Anti-lock Braking System)" (page 4-11). 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 a buzzer will sound when
the air pressure in either the primary or
secondary circuits drops below 70 psi (483 kPa).
If this occurs, stop the coach, determine the
cause of the pressure loss before proceeding.
Warning
: Immediately report any brake
system problem to the maintenance service
personnel.
Warning
: Do not " fan " or " pump " the brake
pedal. This practice does not increase brake
system effectiveness but rather reduces system
air pressure 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.
