Accessories (The Reason for Not Filling the Reservoir all the way is that during retraction of the cylinder fluid from the Butt End of the Cylinder Will return to tank, Causing the Reservoir to Overflow) 12. Run the cylinder Up and Down until all the air is removed from the hydraulic oil. 13. Fill the reservoir to the Full line on Reservoir Label. Approx. one (1) inch from the top KTI DUAL DOUBLE ACTING POWER UNIT (4 BUTTON REMOTE) 139 diagram A-2 diagram A-3 Installation 1) Disconnect the Positive battery cable from the battery. 2) Install 9/16-18 SAE ORB, SAE #6, hydraulic fittings into ports “A”, “B”, “A1” and “B1”. Torque fittings to 18 lb-ft. 3) Mount the Power Unit using two, 3/8-16 UNC mounting bolts (diagram A-2) 4) Remove the Filler/Breather Cap and fill the reservoir with hydraulic oil (see fluid recommendations). Replace the filler/breather cap. 5) Connect Hydraulic Lines to the two cylinders. a) Check the torque specifications for the hose fittings. b) Connect the Base end of the first Cylinder to the port “A” (UP) (Top location) c) Connect the Rod end of the first Cylinder to port “B” (DOWN) (Bottom location) d) Connect the Base end of the second Cylinder to the port “A1” (OUT) (Top location). e) Connect the Rod end of the second Cylinder to port “B1” (IN) (Bottom location). 6) Connect the battery Ground cable to the Ground terminal of the DC Motor (Diagram A-3) 7) Connect the positive cable from the battery to the start solenoid (diagram A-3) (see Battery Cable Gauge table for proper gauge for your length of cables) 8) Holding the bottom nut with a wrench, torque the battery connections to 3 lb-ft. 9) Reconnect the Positive battery cable to the battery. 10) FIRST CYLINDER (UP/DOWN): Extend the first cylinder by pressing the UP button. Keep an eye on the oil level in the reservoir. With the cylinder fully extended, the oil level should not go below ½ full. 11) After the cylinder is fully extended, press the DOWN button to fully retract the cylinder. 12) Extend and retract the first cylinder a few times until all the air is removed from the hydraulic oil.
