SYSTEM
WARNING
FAILURE TO ACT IN ACCORDANCE WITH THE FOLLOWING MAY
RESULT IN SERIOUS PERSONAL INJURY OR DEATH.
The Lippert Hydraulic Slideout System is intended for the sole
purpose of extending and retracting the slideout room. Its
function should not be used for any other purpose or reason than
to actuate the slideout room. To use the system for any reason
other than what it is designed for may result in damage to the
coach and/or cause serious injury or even death.
Before actuating the system, please keep these things in mind:
1. Parking locations should be clear of obstructions that may
cause damage when the slideout room is actuated.
2. Be sure all persons are clear of the coach prior to the
slideout room actuation.
3. Keep hands and other body parts away from slideout
mechanisms during actuation. Severe injury or death may
result.
4. To optimize slideout actuation, park coach on solid and level
ground.
DESCRIPTION
The Lippert Hydraulic Slideout System is a rack & pinion guide system, utilizing a
hydraulic actuator to move the room assembly. The power unite drives the
cylinder rod in a forward and backward motion to drive the slide room in and out.
The Lippert Hydraulic Slideout System is designed to operate as a negative
ground system.

PRIOR TO OPERATION
Prior to operating the Lippert Hydraulic Slideout System, follow these guidelines:
1. Coach should be parked on the most level surface available.
2. Leveling or stabilizing system should be actuated to ensure coach will not
move during operation of Bed Lift System.
3. Be sure battery is fully charged.
4. Be sure to keep all persons and pets clear of Bed Lift System during
operation.
SYSTEM MAINTENANCE
The Lippert Hydraulic Slideout System has been static tested to over 4,000
continuous cycles with out any noticeable wear to rotating or sliding parts. It is
recommended that when operating in harsh environments (road salt, ice build
up, etc.) the moving parts be kept clean and can be washed with mild soap and
water. No grease or lubrication is necessary and in some situations may be
detrimental to the environment and long term dependability of the system.
Electrical System Maintenance
For optimum performance, the slide-out system requires full battery current and
voltage. The battery must be maintained at full capacity. Other than good battery
maintenance, check the terminals and other connections at the battery, the
control switch, and the electric actuator motor for corrosion, and loose or
damaged terminals. Check motor leads under the trailer chassis. Since these
connections are subject to damage from road debris, be sure they are in good
condition.
NOTE: The Lippert Hydraulic Slideout System is designed to operate as a
negative ground system. A negative ground system utilizes the chassis frame as
a ground and an independent ground wire back to battery is necessary (see
page 19 for wiring diagram). It is important that the electrical components have
good wire to chassis contact. Over 90% of unit electrical problems are due to
bad ground connections.
Mechanical Maintenance
Although the system is designed to be almost maintenance free, actuate the
room once or twice a month to keep the seals and internal moving parts
lubricated.
Check for any visible signs of external damage after and before movement of the
travel trailer.
NOTE: For long-term storage: It is recommend that the room be closed
(retracted).

AUXILIARY OPERATION
The Lippert Hydro-Sync Slideout System can be run with auxiliary power devices
like electric drills, ratchet wrenches or cordless screwdrivers. In the event of
electrical or system failure, this manual method of extending and retracting the
slideout room can be used. A standard handheld drill is all that is required. A
standard 38" room will take approximately 45 seconds to retract. See the
instructions below .

MECHANICAL ROOM ADJUSTMENT
V ertical & Horizont al Room Adjustment
NOTE: All slideout room adjustment s must be performed by certified service
technicians. Adjustments made by non-certified persons may void any and all
warranty claims.
Horizontal adjustment
1. Loosen 2 carriage bolts “A” on each bracket located at the end of
each guide tube.
2. Room is ready to be positioned horizontally by pushing on the
outside, sidewall or by using a prying devise inserted into the
opening between the room and coach.
FLUID FILLING PROCEDURE
The Lippert Hydraulic Slideout System uses automatic transmission fluid (ATF).
Any ATF can be used. A full synthetic or synthetic blend works best such as
Dexron III or Mercon 5. For best operation, fill system within ½” of the top when
all slideouts are completely retracted. The see through reservoir makes it easy
to check oil level. It is recommended that the oil level be checked prior to
operating the system. Make sure the breather cap is free of contamination
before removing, replacing or installing.
FILLING DIRECTIONS
Remove Breather/Fill Cap
Pour ATF into Breather/Fill opening.
NOTE: Do not allow any contamination into reservoir during fill process.
NOTE: S tandard reservoir holds approximately 2 quart s (1.89 liters) of
ATF.
Fill to within ½” of top.
Replace Breather/Fill cap when finished.
NOTE: System is self-purging. By simply cycling the system 2-3 times,
any air in the system will be forced back to the reservoir and out of
the Breather/Fill cap.

TROUBLESHOOTING – CHECKING FOR BAD CYLINDER
1. Retract (close) the slideout (room) completely.
2. Loosen hose from “E” (extend) port on the manifold of the Power Unit.
WARNING- Do not attempt to run room out with the “E” port hose loose. The
system will experience RAPID FLUID LOSS.
3. Plug opening on manifold to prevent drawing air into the system.
4. Energize the Power Unit to retract (close) room.
5. Continue to run the room in and watch for fluid flow from hose/port
“E”. Fluid flow greater than a few drops will indicate internal cylinder
leaking (bypassing of piston seal). If there is no fluid flow, reconnect
hose to “E” port and tighten.
WARNING - Be sure to reconnect and tighten hose at the “E” port before
attempting to extend (open) the room or the system will experience RAPID
FLUID LOSS.
Contact qualified technician if there is excessive fluid flow . The cylinder should
not be repaired in the field.
Refill the Power Unit Reservoir as recommended on Page 10 of this manual.
