OPERATING
GENERAL INSTRUCTIONS
After performing the daily inspection and safety checks, you are ready
to operate the motor coach. Safety on the road also depends on you.
Observe weather and road conditions, then drive accordingly. Be
physically and mentally alert.
WARNING
Do not run engine for long periods of time in a closed or poorly
ventilated building, where exhaust gases can accumulate.
If, while driving the motor coach, any of the items below are noticed,
correct condition immediately.
•
STEERING ACTION - Binding, wander, shimmy, excessive steering
wheel play, and pulling to one side.
•
BRAKING ACTION - Increased pedal travel, slow response,
chatter, grabbing, weak, pulling to one side, and excessive air
pressure drop for brake application.
•
VIBRATION - From engine, driveline, accessories, and wheel
imbalance. Scan the instrument panel frequently and be alert for
any changes from normal gauge readings.
Refer to appropriate subject in troubleshooting section of this manual
for detailed data.
ENGINE STARTUP
Engage parking brake. Put the gearshift in the neutral position, making
sure that the rear compartment doors are closed (or engine is
prevented from starting). Insert the key into the ignition start switch and
turn clockwise to the start position. The engine should start within 30
seconds. If starting fails, wait 2 minutes for starter motor to cool down.
Repeat start procedure until the engine starts.
Do not run a cold engine at high rpm. Idling too fast during warm-up will
cause too rapid and uneven expansion, resulting in premature engine
wear. The rpm should be increased gradually after starting a cold
engine.
Do not operate the motorcoach at high rpm until the engine water
temperature reaches 158°F (70°C).
CAUTION
Damage may occur if engine idles for more than 10 minutes at low
rpm. Idling the engine too slowly does not allow sufficient splash
lubrication of cylinder walls and may result in excessive wearing
of pistons and liners.
There must be a display of the oil pressure on the instrument panel
within 15 seconds after starting the engine, otherwise stop the engine
and correct problem immediately.
If the parking brake indicator on the instrument panel is illuminated, the
parking break is engaged.
