Drive-away Protection:
With the jacks extended and the park brake
is released or transmission placed in gear,
a warning alarm will sound and all LEDs
will illuminate. The jacks will automatically
retract. A full visual inspection is required to
conrm full retraction of jacks before moving
motorhome.
Maintenance:
At weekly intervals, use 100% silicone spray
on the jack rod. This will help prevent moisture
damage to surface of the jack rod. If parked
near coastal areas, apply more frequently.
Occasional oil or grease on the extended jack
rod is normal.
Remove dirt and road debris from the
jacks as needed.
Check the uid level every month with
all jacks retracted. The uid level should
begin to ow from the weep hole.
Inspect and clean all hydraulic pump
electrical connections every 12 months.
For jacks equipped with a grease tting
at the bottom of the cylinder, two pumps
of grease should be sufcient for 20 to 30
uses. DO NOT over grease. Damage to
the rod seal will occur.
Fluid change interval is 36 months.
Adding Fluid:
If the leveling system makes unusual noise or
the alarm sounds when driving around corners or
over bumpy roads, this indicates a low uid level.
1. Chock all wheels for safety.
2. Ensure all jacks are retracted.
3. Unscrew the ll plug from the top of
the pump. Slowly ll the reservoir with
Dexron 3 Mercon ATF hydraulic uid
until ¼" from the ll plug.
4. Replace the plug.
engIne - general InformatIon
The diesel engine operates differently from the
conventional gasoline engine. Gasoline engines
control engine speed using a buttery throttle
plate controlling air/fuel mixture inlet ow. 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. The maximum engine speed on a
diesel engine is controlled by an engine speed
governor set by the engine manufacturer.
