Selecting A Site

When the coach is parked on an excessive slope, the leveling requirements may exceed the jack lift stroke capability. For angles greater than 1.0 degree, leveling blocks and jack pads may be required in order to level properly. If the coach is parked on an excessive slope, the coach should be moved to a more level surface before the leveling system is deployed. "EXCESS ANGLE" will appear on the LCD screen if the coach is 3.5 degrees out of level from front-to-rear, or side-to-side.

Zero Point Calibration

Before auto-leveling features can be made available, the Zero Point MUST be set. This is the point to which the system will return to when an auto-leveling cycle is initiated. To set the Zero Point, first run a manual leveling sequence to get the coach to the desired level point. Then activate the Zero Point configuration mode. This mode is enabled by performing the following sequence:

1. Turn panel off.
2. Press the FRONT button (Fig. 1G) five times.
3. Press the REAR button (Fig. 1J) five times.
4. At this point, an alarm will sound and the LCD display will read "**ZERO POINT CALIBRATION** ENTER to Set, POWER to Exit."
5. Press ENTER (Fig. 1C) to set the Zero Point.
6. Screen will then display "PLEASE WAIT."
7. Alarm will sound and the screen will display "ZERO POINT SUCCESSFUL."
8. LCD will display "configuring air feature".
9. Control will then turn off.

Automatic Leveling Procedure

1. Press "On/Off" button to turn system on (Fig. 1K).
2. Press AUTO LEVEL button (Fig. 1F). LCD Screen will display "Remain Still."
3. The coach will level automatically and indicate "Auto Level - Success" in the LCD display (Fig. 1E)

Automatic Leveling Descriptive Logic

Grounding:

The following steps describe the process of how the auto leveling sequence extends the jacks to the ground:

1. Depending on which end of the coach is lowest to the ground, the level sensor in the controller will activate the jacks—the lowest end first, either front or rear.

• If the rear of the coach is the lowest end, ground the lowest rear jack first.
• If the front end is the lowest end, ground the front jack closest to the power unit.

2. Ground the remaining front or rear lowest end jack.
3. Lift lowest end jacks together until level.
4. The leveling system will then ground remaining end jacks.

• If the rear of the coach is the remaining end, ground lowest jack first.
• If the front of the coach is the remaining end, ground the front jack closest to the power unit.

5. Ground the remaining front or rear remaining end jack
6. Lift remaining end jacks together until level.
7. Visually inspect all jacks to ensure all footpads are touching the ground. If one of the rear jack footpads is not touching the ground, put the system in manual mode. See Manual Leveling Procudure then press the corresponding LEFT or RIGHT arrow buttons to lower the non-compliant jack to the ground.

Leveling: 

The following steps describe the process of how the auto leveling sequence levels the coach, once the jacks have been grounded. This process may repeat several times until level.

1. Front-to-Rear
2. Side-to-Side
3. Individually
4. Minor adjustments to confirm grounding.

Manual Leveling Procedure

1. Press Power Button (Fig. 1K) to turn system on.
2. Press UP or DOWN button (Fig. 1A and 1B) to scroll through features to “MANUAL MODE” in display. 
3. Press ENTER (Fig. 1C).
4. Press FRONT button (Fig. 1H) to extend front jacks to the ground; press REAR button (Fig. 1I) to run rear jacks to the ground and level the coach front-to-back.
5. Press appropriate LEFT or RIGHT button to level the coach from side-to-side. Red lights next to the buttons on the touchpad will indicate which side(s) of the coach needs to be raised to achieve level condition.

6. Repeat steps 4 and 5 as needed.
7. Turn power off to leveling system by pressing Power Button (Fig. 1K).
8. Visually inspect all jacks to ensure all footpads are touching the ground. If one of the rear jack footpads is not touching the ground, press the corresponding LEFT or RIGHT arrow buttons to lower the noncompliant jack to the ground.

Jack Retract Procedures

1. Energize the system by pressing Power Button (Fig. 1K) on touchpad. The LCD screen will display "READY Jacks: Down."
2. Press UP or DOWN button (Fig. 1A) to display "Auto Retract All" on the screen.
3. Press ENTER (Fig. 1C) to begin.

4. The jacks will retract and shut off automatically; the display will read "READY - Jacks: Up." Press the "ON/OFF" button (Fig. 1K) on the touch pad to de-energize the system. After a brief visual inspection around the coach to verify the jacks are fully retracted, you may proceed to travel.
5. To retract in the manual mode, press the RETRACT button (Fig. 1D) until it lights. Pressing the FRONT or REAR jack buttons will operate front or rear jacks in pairs. Pressing the RIGHT or LEFT jack buttons will operate the right or left rear jacks individually.

Maintenance

Fluid Recommendation

Automatic transmission fluid (ATF) with Dexron®III or Mercon®V or a blend of both is recommended by Lippert Components, Inc. For a list of approved fluid specifications, see TI-188. To obtain this Technical Information sheet on-line, go to http://www.lci1.com/support-lci4a3lcd. Then click on the Technical Information Sheets tab. Look for TI-188: Hydraulic Operation Fluid Recommendation within the listing.

Preventive Maintenance

1. Check hydraulic fluid in reservoir every 12 months. If fluid is a clear, red color do not change. If fluid is milky, pink and murky and not clear red in color, drain reservoir and add new fluid. Hydraulic fluid in reservoir should be changed a minimum of every five years.
2. Inspect and clean all power unit electrical connections every 12 months. If corrosion is evident, use a small amount of lubricant to remove corrosion. Contacts must be cleaned with a non-residue cleaner prior to use. LCI recommends the use of an electrical contact cleaner spray.
3. Remove dirt and road debris from jacks as needed.
4. If jacks are down for extended periods of time, it is recommended to spray exposed jack rods with a dry silicone lubricant every three months for protection. If the coach is located in a salty environment, it is recommended to spray the rods every 4 - 6 weeks.
