Leveling and Full Wall Slideout Sequence of Operation
This article provides step-by-step instructions for leveling the coach and operating the slideouts.
In the past, Newmar has recommended leveling the
coach prior to deploying the slideouts. As of 2015,
Newmar makes the following recommendation for the
extension and retracting of slideouts.
IMPORTANT
!
Extending The Slideouts and
Leveling The Coach
1. Park the coach on a reasonably level campsite.
2. Leave the coach at ride-height with air in the air
bags (if equipped with air suspension) or on normal
suspension (coaches without air suspension).
3. Plug the coach into shore power (if available) or
start the generator to increase the voltage for better
slideout operation.
4. Look at the “reveal” or “gap” of the two vertical
wall trims around the slideouts to make sure there
is plenty of clearance so the trim will not rub when
extending the slideout. If the gap looks good, then
the slideout can be operated.
•
Note: Most often the gap will look best when
sitting on the tires with the air suspension inflated
(at ride-height), and not on the jacks.
Motorhomes, like all vehicles, flex in travel. Flexing may be
different due to terrain and the coach’s fulcrums (resting on
tires or jacks). As the coach flexes, this movement is more
noticeable in the outside reveal on a wider slideout.
In the unlikely occasion that the slideout trim has
inadequate clearances, try leveling or repositioning
the coach and rechecking the clearances before
extending the slideout.
IMPORTANT
!
Care and Maintenance
The leveling system should be cycled at least once a
month to keep the system in operating condition.
IMPORTANT
!
5. Verify that the path of the slideout is unobstructed
and free from any surrounding objects, both inside
and outside of the coach.
WARNING
!
Be sure the ground on which you are parked will
support the weight of your unit. Often material that
seems “safe” to level on will not support the weight
at the leveling jack points. Use caution when leveling
on hot asphalt, sand, and grass, as the weight of the
unit may cause the jacks to sink into the ground. Pads
may need to be placed under the jacks to spread the
weight over a larger area. Always look under your unit
prior to leveling to make sure the jacks are clear of
debris and other foreign materials that may interfere
with leveling.
WARNING
!
Never operate any leveling system with a person or
pet under the unit. Serious injury or death may result!
6. Once the appropriate conditions are met, follow the
operating instructions posted in your coach to extend
the slideouts.
7. Dump the air suspension (if equipped). This step
is included in the auto-leveling process for most
coaches.
8. Deploy the leveling jacks.
1.
Retract the leveling jacks.
2.
Start the coach.
3.
Allow the coach air suspension
to fill and return to ride
height (units without air
suspension will return to normal
suspension).
4.
Turn the engine off.
5.
For a full wall slideout, visually
inspect the front vertical trim
for adequate clearance. The
spacing should look even from top to bottom (see
image for reference).
Retracting The Jacks and
Slideouts
In the unlikely occasion that the slideout trim has
inadequate clearances, try leveling or repositioning
the coach and rechecking the clearances before
retracting the slideout.
IMPORTANT
!
6.
Verify that the path of the slideout is unobstructed and
free from any surrounding objects, both inside and
outside of the coach. This includes any water or debris
that may have collected on the slideout roof or the
topper awning.
