BEFORE YOU SERVICE THE COACHWARNING DO NOT USE THE POWER GEAR HYDRAULIC LEVELING SYSTEM (OR AIRSUSPENSION) TO SUPPORT VEHICLE WHILE UNDER COACH ORCHANGING TIRES. THE HYDRAULIC LEVELING SYSTEM IS DESIGNED ASA ‘LEVELING’ SYSTEM ONLY. TIRE REPAIRS SHOULD BE PERFORMED BYA TRAINED PROFESSIONAL. ATTEMPTS TO CHANGE TIRES WHILESUPPORTING THE VEHICLE WITH THE HYDRAULIC SYSTEM COULDRESULT IN DAMAGE TO THE MOTOR HOME AND/OR CAUSE SERIOUSINJURY OR EVEN DEATH. KEEP PEOPLE CLEAR OF COACH WHILE LEVELING SYSTEM IS IN USE. NEVER LIFT THE WHEELS OFF THE GROUND TO LEVEL THE COACH.DOING SO MAY CREATE AN UNSTABLE CONDITION. NEVER EXPOSE HANDS OR OTHER PARTS OF THE BODY NEARHYDRAULIC LEAKS.HIGH PRESSURE OIL LEAKS MAY CUT ANDPENETRATE THE SKIN CAUSING SERIOUS INJURY. DO NOT USE A HIGH PRESSURED WASH/RINSE SYSTEM ON ANY OF THECOMPONENTS ASSOCIATED WITH THE LEVELING SYSTEM. THISINCLUDES THE PUMP, PUMP MOTOR, WIRING HARNESS, CONTROL, ANDTOUCHPAD. THE USE OF A HIGH PRESSURE WASH/RINSE SYSTEM WILLVOID THE WARRANTY.CAUTION - PARK THE COACH ON A REASONABLY SOLID SURFACE OR THEJACKS MAY SINK INTO GROUND. ON SOFT SURFACES, USE LOADDISTRIBUTION PADS UNDER EACH JACK.CAUTION - CHECK THAT POTENTIAL JACK CONTACT LOCATIONS ARE CLEAROF OBSTRUCTIONS OR DEPRESSIONS BEFORE OPERATION.3
BEFORE YOU OPERATE THE SYSTEM:1. Make sure jack cylinder paths from the coach to the ground are clear andfree of obstructions.2. Make sure that the coach does not have objects leaning against the sides ofit. As the coach will rise when the jack cylinders engage the ground and startto lift, moving the coach.3. Place blocks under the jack cylinder foot pads for soft or low ground issues.Use as many blocks as needed to bring the depression, equal to or abovethe surrounding ground level.4
MAJOR COMPONENT DESCRIPTIONSYSTEM DESCRIPTION - The Power Gear electro-hydraulic leveling system consists of the followingmajor components:(A) Touch Pad that is located inside the cab area of the coach. The touch pad communicates the inputfunctions to the control box and receives status signals from the control. The available touch padsare: Manual touch pad (Part # 500731). Does not use a separate control box. Semi-Automatic touch pad (Part #'s 500675 or 140-1231). These use a separate control box. Automatic touch pad (Part #'s 500629 or 140-1226). These use a separate control box.(B) Control Box which has an internal leveling sensor and levels the coach to a calibrated point; it ismounted upside down inside a water proof location in the center of the coach. Contact the O.E.Mfor exact location. The control box communicates with the hydraulic pump assembly and the touchpad. A new or replacement control box does not have a stored level point; this must be set afterinstallation. See reference documents for calibration procedure. The available control boxes are: Semi-Automatic control box (Part #'s 500674 or 140-1230). Automatic control box (Part #'s 500630, 140-1227, 1010001284, 1010001002 and 9010000156).(C) Hydraulic Pump Assembly that consists of these components: motor, motor starter solenoid,pump, reservoir tank and manifold assembly. The manifold assembly has leg valve assemblies anda dump valve assembly. There is a manual override leg or dump valve with a trailer style connectoror a packard style connector. There is also a non-override leg or dump valve with a trailer styleconnector or a packard style connector.(D) Hydraulic Hoses are used to connect the hydraulic pump assembly to the jack leg cylinders. Thehoses are rated according to the output pressure of the pump assembly.(E) Jack Leg Cylinders with either internal or external springs that are rated at a lifting capacityappropriate for your coach. Each jack has a large 10" diameter (78.5 square inch) shoe formaximum mating area on different surfaces. External spring jacks have a spring that is mountedexternally and connected both to the top at the jack bracket and to the shoe of the jack. Internalspring jacks have a spring welded to the inside top of the jack and connected to the top of thechrome rod.D) Hydraulic HosesItem AC) Hydraulic Pump AssemblyE) Jack Leg Cylinders5Item BTouch Pad and Control Box
RECOMMENDED HYDRAULIC FLUIDSThe fluids listed here are acceptable to use in your pump assembly. Contact the coach manufactureror selling dealer for information about what specific fluid was installed in your system.Please consult factory before using any other fluids.In most applications, Type A automatic transmission fluid (ATF, Dexron III, etc.,) will work satisfactorily. Mercon V is also recommended as an alternative fluid for Power Gear leveling systemsoperating in environments with large temperature swingsOperating in cold temperatures (less than -10 F) may cause the jacks to extend and retract slowly. Forcold weather operation, fluid specially-formulated for low temperatures may be desirable, Mobil DTE 11M, Texaco Rando HDZ-15HVI, Kendall Hyden Glacial Blu, or any Mil. Spec. H5606hydraulic fluids are recommended for cold weather operation.PREVENTATIVE MAINTENANCE PROCEDURESTo retain the quality for the leveling system use genuine Power Gear parts and service assistance. Forthe correct part or information for a particular leveling system always mention the part number listed onthe major components label before contacting Power Gear or the OE.M. Also know the year, make,and model of the RV you are working on for further assistance.WARNING:Your coach should be supported at both front and rear axles with jack stands beforeworking underneath, failure to do so may result in personal injury or death.1. Check the fluid level every month. Fill the reservoir with the jacks in the fully retractedposition. On vertical pump assemblies, the fluid should be within 1/4 inch of the fill port lipand checked only with all jacks retracted. On horizontal pump assemblies, the fluid levelshould be up to the weep hole on the side of the reservoir tank and checked only with alljacks retracted.2. Change fluid every 24 months.3. Inspect and clean all hydraulic pump electrical connections every 12 months.4. Remove dirt and road debris from jacks as needed.5. If jacks are down for extended periods, it is recommended to spray exposed chrome rodswith a silicone lubricant every seven days for protection. If your coach is located in a saltyenvironment (within 60 miles of coastal areas), it is recommended to spray the rods every 2to 3 days.6. Jacks equipped with grease fittings at the bottom of the cylinder should be greased withlight weight lithium grease using a hand pump style grease gun only. 2 or 3 pumps shouldbe sufficient for every 20-30 uses.7. Do not use a high pressured was/rinse system on any of the components associated with theleveling system. This includes the pump, pump motor, wiring harness, control and touchpad.THE USE OF A HIGH PRESSURE WASH/RINSE SYSTEM WILL VOID THE WARRANTY.6
GENERAL OPERATING INSTRUCTIONSTO EXTEND THE JACKS:1. Start the engine of the coach; this will insure proper voltage to the fuse which feeds the motorstarter solenoid and control box. This fuse is provided by the O.E.M.; contact them for locationand size. The batteries provide voltage to the hydraulic pump assembly and control box forcorrect operation. Some controls require a minimum of 13.1VDC to come out of "WAIT"mode.2. Power the touch pad on by pressing the ON/OFF button. The LED will light up under thebutton indicating the touch pad is on. The touch pad will communicate with the control box topower the touch pad on; the control box will now be ready to accept the next input function.3. Choose the function of manually leveling (MAN button) or automatically leveling (AUTObutton) the coach by selecting the corresponding button. Press the AUTO button and it will dump the air (if using the 4 pin AUX connector on thecontrol box, and it is programmed accordingly) and the system will level the coach to thecalibrated point stored in the control box. Press and hold the MAN button for 5 seconds until the LED is lit under the button and it willdump the air (if using the 4 pin AUX connector on the control box, and it is programmedaccordingly). Use the 4 directional buttons to extend the jacks. Pressing right button willoperate the right rear jack; pressing left button will operate the left rear jack. Pressing thefront button will operate both front jacks. Pressing the rear button will operate both rearjacks. The touch pad communicates with the control box to energize the leg valve(s) to extend thejack(s) and level the coach.4. Turn off the touch pad. The touch pad stops communicating with the control box.5. Turn off the ignition. The control box removes the power for the touch pad.TO RETRACT THE JACKS:1. Start the engine of the coach, this will insure proper voltage to the fuse which feeds the motorstarter solenoid and control box. This fuse is provided by the O.E.M.; contact them for locationand size.2. Power the touch pad on by pressing the ON/OFF button. The LED will light up under thebutton indicating the touch pad is on. The touch pad will communicate with the control box,and will now be ready to accept the next input function from the touch pad.3. Press and release the RETRACT ALL JACKS button. The touch pad communicates with thecontrol box to energize the leg valves and the dump valve on the hydraulic pump assembly.The jack springs pull on the foot pads and push the fluid back into the reservoir tank of thehydraulic pump assembly.4. When the jacks are fully retracted the "jacks down" light on the touch pad will go off. When thefloat switch rises to the "open" position in the reservoir tank of the pump assembly, this iscommunicated to the control box, which then turns off the jacks down light on the touch padwithin 20-30 seconds.7
