Lubrication Maintenance - Holiday Rambler Imperial 2008 Owner's Manual

CHASSIS INFORMATION — 10
DPF Dash Light:
A DPF (Diesel Particulate
Filter) indicator light on the
dash illuminates when an
active regeneration cycle is
necessary and has not been
able to initiate. Driving the
motorhome above speeds
of 20 mph will allow an
active regeneration cycle
to initiate. The HEST light will turn on when
exhaust temperatures reach 1450º F, indicating
an active regeneration cycle is underway. Once
the DPF is clear of particulate matter the DPF
light will turn off.
DPF Light Warning System:
If the DPF remains clogged, there are four
stages of the DPF light warning system.
The HEST light may illuminate during this
sequence, which indicates that an active
regeneration cycle is underway. This should
successfully regenerate the fi lter. The only
indication that the DPF is clear and in good
working order is the DPF light turning back off.
Stage One: The DPF light glows steady.
This means that an active regeneration
cycle is necessary but has not been able
to initiate.
Stage Two: The DPF light fl ashes. The
DPF fi lter is clogged to the point that the
engine will slightly derate (lose power).
256
Stage Three: The DPF light fl ashes and
the Check engine light turns on. The
DPF is clogged to the point that service
is immediately required. The engine will
severely derate at this point.
090502
Stage Four: The DPF light and Check
DPF Dash Light
Engine lights extinguish and the Stop
Engine light turns on. Turn off the
engine as soon as possible to avoid
severe engine and/or system component
damage. Do not drive the motorhome in
this condition. The DPF will need to be
removed for repair.

LUBRICATION MAINTENANCE

Performing regular scheduled maintenance
ensures reliable operation and optimum
service life of the various chassis components.
Completed maintenance brings peace of mind
knowing the various components have received
proper service. Failure to follow maintenance
guidelines, or perform scheduled maintenance,
results in ineffi cient operation, premature
component wear or component failure resulting
in breakdown.
Maintenance schedules are usually performed
at certain mile or time intervals. When
performing high level procedures, lower level
service should also be performed.
NOTE:
Maintenance schedules are based on
normal operating conditions and use.
Operating under unusual or adverse
condition shortens service intervals.

NOTE:
Engine and transmission service intervals
are listed in their respective manuals.
Proper Lubricant Waste Disposal:
When performing service maintenance on
the engine, transmission or rear axle, waste
fl uids and fi lters should be properly disposed of
or recycled. Package used oils, antifreeze and
other fl uids in sealed containers. In many cases
used oil is accepted free of charge at county
disposal sites. Waste fl uids are toxic to pets and
other animals. Waste fl uids should not be left in
open containers. The sweet odor of antifreeze is
attractive to pets, but highly toxic.
CAUTION:
Properly dispose of used antifreeze and
waste oil. Animals like the sweet odor
of antifreeze and may ingest it if left in
open containers. Wipe up any fluid spills.
Pets may lie in puddles of fluid, many of
which are irritants and can cause severe
chemical burns if not properly washed.
Lubricant Classifi cation:
Lubricants are manufactured in many forms for
a variety of applications. There are many different
oil and grease consistencies each with a designed
application. To properly select a particular type of
lubricant for a specifi c application, the component
must be evaluated. Component stress loads,
ambient temperature, working temperature and
environmental exposure are just a few of the
variables to consider. Select the proper lubricant
for its intended application. As an example:
selecting high viscosity grease to lubricate a lock
cylinder results in sluggish lock cylinder operation
especially in a cool environment.
