To Fill the Reservoir:
1. Turn the ignition switch to the ON position. Turn the
jack control
Power
switch ON.
2. Extend any jack six inches from the fully retracted
position. All other jacks remain fully retracted.
3. Unscrew the reservoir cap from the top of the reservoir.
4. Open a window or the entry door so the bong alarm is
audible from outside the motorhome. Slowly fill the
reservoir with fluid until the bong alarm stops sounding.
5. Replace the reservoir cap.
6. To retract the extended jack, push the
RETRACT
button.
7. Turn the jack control
Power
switch OFF.
8. Turn OFF the ignition switch.
The diesel engine operates differently from the conventional gasoline engine.
Gasoline engines control engine speed using a butterfly throttle plate controlling
air/fuel mixture inlet flow. As the throttle plate opens, vacuum created by the piston
velocity draws the metered fuel/air charge into the combustion chamber, then ignites
from a controlled electric ignition source. Closing the throttle plate limits the
fuel/air supply, slowing engine speed, increasing intake manifold vacuum.
The diesel engine in the motorhome controls engine speed by varying fuel supply
only. No throttle plates are used. An exhaust driven turbine system (turbocharger)
compresses the fresh air supply into the engine. The fuel is injected under pressure
into the combustion chamber. Ignition of fuel/air charge occurs from heat generated
by rapid high compression. The turbo boost gauge registers amount of intake manifold
pressure measured in lbs./in². Therefore, no intake manifold vacuum exists.
Diesel engine RPM (revolutions per minute) operating speeds are generally
much lower than that of the gasoline engine. Peak torque and horsepower output
values occur at much lower engine speeds. Idle speeds between the two engine
types are similar, however maximum engine speeds are quite different. The
gasoline engine generally is not regulated to a maximum engine speed. An engine
speed governor set by the engine manufacturer controls the maximum engine
speed on a diesel engine.
WARNING: Do not operate a diesel engine where there are or can be
combustible vapors. Vapors can be drawn through the air intake system
and cause engine acceleration and over-speeding, resulting in fire,
explosion and extensive property damage. Numerous safety devices are
available, such as air intake shutoff devices, to minimize risk of engine
over-speeding where an engine (due to its application) might operate in
a combustible environment, such as fuel spills or gas leaks. The equipment
owner and operator is responsible for safe operation of engine.
INFORMATION: Consult your engine authorized repair location for
future information.
