Remove the pump top cover, then the silver sticker on the end of the motor, and drive the override coupler with a drill capable of at least 2000 rpm, using a 1\/4 inch (6mm) Allen drive hex key. 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\u003ch4\u003eWhy the heavy cylinder matters\u003c\/h4\u003e\u003cp\u003eThe 3 inch cylinder with a 2 inch shaft and the 12 inch foot pad are what separate this from a standard SL 24.

Flooded lead acid, gel and AGM types are all suitable. Some lithium batteries cannot deliver the running amperage this system needs, so check with the battery manufacturer before fitting one.

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\u003ch4\u003eDocuments\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/EQS03R11-EQ-Systems-Trailer.pdf\" target=\"_blank\"\u003eEQ Systems Lifting Systems for Any Size Trailer (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/Jack-Replacement-Chart-Cylinder-Foot-identification-2025-V2.pdf\" target=\"_blank\"\u003eJack Replacement Cylinder and Foot Identification Chart (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/EQS1004R3-EQ-Systems-Commercial.pdf\" target=\"_blank\"\u003eEQ Systems Hydraulic Jack Options, commercial range (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/cdn\/shop\/files\/Required-Maintenance-Items-Hydraulic-Systems-EQ-TM.pdf\" target=\"_blank\"\u003eRequired Maintenance Items for EQ Systems Hydraulic Jacks and Slide Systems (PDF)\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EQ Systems","offers":[{"title":"Default Title","offer_id":43958749167675,"sku":"8662","price":1175.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0690\/2608\/6971\/files\/SL-24-2.jpg?v=1786536995","url":"https:\/\/eqsystems.us\/products\/sl-24-heavy-duty-stacker-trailer-jack","provider":"EQ Systems","version":"1.0","type":"link"}
