The AJ series is the 3.5\" x 3.5\" square tube in tube jack, and this system lifts 8,000 lbs. The rocker switch control replaces cranking a manual jack, which on a loaded horse or motorsports trailer is the difference between a two minute hook up and a fight.\u003c\/p\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSeries\u003c\/th\u003e\n\u003ctd\u003eAJ series tube in tube\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eLegs\u003c\/th\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eLifting capacity\u003c\/th\u003e\n\u003ctd\u003e8,000 lbs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eStroke length\u003c\/th\u003e\n\u003ctd\u003e24\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTube size\u003c\/th\u003e\n\u003ctd\u003e3.5\" x 3.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eRetracted length\u003c\/th\u003e\n\u003ctd\u003e35.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eExtended length\u003c\/th\u003e\n\u003ctd\u003e59.5\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCylinder bore\u003c\/th\u003e\n\u003ctd\u003e2\"\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eManual override\u003c\/th\u003e\n\u003ctd\u003eScrew drive output shaft\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eControl\u003c\/th\u003e\n\u003ctd\u003eWeatherproof switchgear with rocker switch and key, standard\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch4\u003eManual override: screw drive\u003c\/h4\u003e\n\u003cp\u003eIf the system loses power, the jack can be driven with a drill through the manual override output shaft in the center of the top of the motor. Remove the pump cover, then the foil seal on top of the motor, and drive the override shaft with a reversible drill capable of at least 2000 rpm, using a 6mm (1\/4 inch) Allen hex key. Clockwise retracts the jack and counterclockwise extends it. Take care that the drill does not contact wires or hoses. The drill has to reach 2000 rpm or the pump will not develop enough pressure to move the jack.\u003c\/p\u003e\n\u003ch4\u003eStandard and optional equipment\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eCommercial single function pump with manual override screw drive\u003c\/li\u003e\n\u003cli\u003eSteel pump cover\u003c\/li\u003e\n\u003cli\u003eWeatherproof switchgear control with key standard, which also prevents unauthorized use of the system\u003c\/li\u003e\n\u003cli\u003eWireless remote option, part \u003ca href=\"https:\/\/www.eqsystems.us\/products\/remote-control-part7823\" target=\"_blank\" rel=\"noopener\"\u003e7823\u003c\/a\u003e for single function jacks\u003c\/li\u003e\n\u003cli\u003eUniversal mounting brackets included\u003c\/li\u003e\n\u003cli\u003eWire harnesses have a PVC high temperature nylon braid to hold up in the toughest environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eBattery requirement\u003c\/h4\u003e\n\u003cp\u003eEQ Systems recommends load testing the battery: it should deliver a minimum of 150 amperes at a minimum of 10.5 VDC for at least 30 seconds.

An AJ single leg system runs on Dexron III ATF, filled to about one inch below the top of the reservoir with the jacks fully retracted. Remember the level rises as the jacks retract. The reservoir must run with its vented breather cap fitted, not the flush shipping plug, or the jack will operate erratically. EQ Systems recommends owners inspect the system every 12 months, checking that all connections are tight and free from corrosion, particularly the ground to the pump stud and the positive cable to the motor solenoid.\u003c\/p\u003e\n\u003ch4\u003eService parts\u003c\/h4\u003e\n\u003cp\u003eThe replacement hydraulic cylinder for this jack is part \u003ca href=\"https:\/\/www.eqsystems.us\/products\/aj-70-cylinder\" target=\"_blank\" rel=\"noopener\"\u003e2505EQ\u003c\/a\u003e.
