Section 7: Leveling and Slideout Systems
Hydraulic Leveling System Safety
• FAILURE TO ACT IN ACCORDANCE WITH THE
FOLLOWING INSTRUCTIONS MAY RESULT IN DEATH
OR SEVERE INJURY.
• READ THE ENTIRE OPERATORS MANUAL AND
ALL PRECAUTIONS PRIOR TO OPERATING THIS
EQUIPMENT.
• DO NOT ATTEMPT TO OPERATE THE SYSTEM WHILE
THE MOTORHOME IS IN MOTION. IF THE ‘JACKS
DOWN’ ALARM SOUNDS WHILE DRIVING THE
MOTORHOME, IMMEDIATELY FIND A SAFE PLACE
TO PULL OVER AND STOP. SET THE PARKING
BRAKE AND WHEN IT IS SAFE, INSPECT THE
LEVELING SYSTEM.
DANGER
• DO NOT OPERATE ANY SYSTEM FUNCTIONS WHILE
ANYONE IS UNDER THE MOTORHOME. IF WORK
UNDERNEATH YOUR MOTORHOME IS REQUIRED,
SUPPORT BOTH FRONT AND REAR AXLES WITH
JACK STANDS. DO NOT RELY ON THE SUPPORT OF
THE LEVELING SYSTEM! FAILURE TO DO SO MAY
RESULT IN DEATH OR SEVERE INJURY.
• DO NOT USE THE LEVELING JACKS TO CHANGE
TIRES. THE SYSTEM IS DESIGNED FOR LEVELING
AND STABILIZING AND IS NOT MEANT TO LIFT THE
WHEELS OFF THE GROUND! LIFTING THE WHEELS
OFF THE GROUND MAY RESULT IN AN UNSTABLE
VEHICLE CONDITION, WHICH MAY RESULT IN
DEATH OR SEVERE INJURY.
• MAKE SURE THERE ARE NO OBSTRUCTIONS
IN THE 'EXTEND' OR 'RETRACT' PATHS OF THE
LEVELING JACKS. KEEP ALL PEOPLE AND PETS
CLEAR OF THE MOTORHOME WHILE OPERATING
THE LEVELING SYSTEM. ALWAYS VISUALLY
CONFIRM THE JACKS HAVE FULLY RETRACTED
BEFORE MOVING THE MOTORHOME. MOVING THE
MOTORHOME WHILE THE JACKS ARE EXTENDED
COULD CAUSE DAMAGE TO THE JACK SYSTEM
AND THE MOTORHOME.
• NEVER EXPOSE HANDS OR OTHER PARTS OF THE
BODY NEAR HYDRAULIC LEAKS. HIGH-PRESSURE
OIL LEAKS MAY CUT AND/OR PENETRATE THE SKIN
CAUSING SEVERE INJURY.
• ALWAYS DISCONNECT TRAILERS OR TOWED
VEHICLES FROM THE MOTORHOME'S HITCH
BEFORE USING THE LEVELING SYSTEM.
WARNING
MOTORHOMES WITH AIR SUSPENSION:
Before lowering (dumping) the air suspension, always
ensure that the front wheels are pointing straight-ahead.
Damage due to contact of the front tires with wheel wells
and body panels is possible.
CAUTION
OPERATE THE HYDRAULIC LEVELING SYSTEM ONLY
UNDER THE FOLLOWING CONDITIONS:
• Be sure all persons, pets, and property are clear of
your motorhome while operating the leveling system.
• If you are operating an automatic system with
occupants inside the motorhome, they must stay
seated during the leveling process. Shifting weight
inside the motorhome can disrupt the leveling
system’s sensing mechanism, while motorhome
movements could cause falls or personal injuries.
CAUTION
• The chosen parking site may present surface
irregularities that would require leveling distances
beyond the deployment stroke of the leveling jacks.
Blocks may need to be placed under the jack support
pads to effectively increase their stroke length;
however, be aware that blocks can be somewhat
unstable. If possible, re-position the motorhome to
a more at and uniform parking area so that blocks
are not needed.
• If one or more wheels remain off the ground after
attempting to level the motorhome by automatic or
manual leveling, move the motorhome to a more
level location.
• Soft soils and surfaces may require the use of
enlarged jack pads, boards, or other devices that
increase the contact surface area of the jack support
pad.
• For the hydraulic leveling system to operate (extend
or retract), the motorhome’s engine MUST be running
with the gear selector in PARK and the parking brake
must be ENGAGED.
• For DIESEL PUSHERS ONLY: the engine MUST be
running, while the gear selector is in NEUTRAL and
the parking brake is engaged.
