Replace the Filler Plug (16).<br><br> 6. OperAtiOn This is an air-actuated hydraulic bottle jack. The air motor is air pressure activated and drives the hydraulic jack.<br><br> In the event no air pressure is available, a standard hydraulic piston assembly is provided 5or hand jacking. Position the Jack on a solid level sur5ace that can withstand the weight o5 the jack and 1. the load which will be li5ted.<br><br> Be sure the load is balanced on the jack. Sturdy jack stands (not included) positioned under 2. the weight provide a good sa5ety precaution against the possibility o5 the load toppling.<br><br> Be sure that the jack is positioned at a proper li5t point on the item to be li5ted. Using 3. appropriate li5t points avoid possible damage to the item.<br><br> Rotate the Screw Extension (13.1) on the Ram (13) until it contacts the underside o5 the load to be li5ted. Screwing counterclockwise raises the extension, screwing clockwise lowers the extension. 4a.<br><br> Pneumatic Operation: Connect a pressurized air source to the Air Valve (44). a. Engage the notch on the end o5 the Jack Handle (45) onto the Release Valve (4).<br><br> b. Turn the Release Valve slightly clockwise to ensure that the valve is closed. The jack will not li5t i5 the valve is open.<br><br> When it is sa5e to do so, squeeze the Air Valve (44). This will admit pressurized air c. into the Air Motor (42) which will cause the hydraulic jack to li5t.<br><br> Continue to hold the Throttle Lever down until the load is li5ted to the desired level. Note that the maximum ram travel is 6-½ d. 4b.<br><br> Manual Operation: To manually operate the jack without use o5 compressed air, close the Release Valve, then insert the end o5 the Jack Handle (45) into the Handle Bracket (34) and pump up and down. This action will raise the jack. Support the load using jack stands (not included) or other means to support the weight.<br><br> 5. Do not leave the load on the jack 5or an extended period o5 time. Damage to the jack or personal or property injury may result.<br><br> To lower the item, rst li5t the item slightly and remove the jack stands. 6. Engage notches in the end o5 the Jack Handle (45) onto the Release Valve (4).<br><br> Turn the 7. valve slightly, approximately 1/4 turn to lower the load. When the load is lowered, turn the Release Valve clockwise to stop the motion.<br><br> SKU 95553 Fo= ?0.h94.a7 q@0>?4o9> ;70a>0 .a77 1-800-444-3353 .

Periodically lubricate all moving points o5 the Jack. 2.<br><br> The Hydraulic Ram (13) should be kept clean, 5ree o5 dirt and water, and protected 5rom 3. corrosion. Oil replAceMent: 4.<br><br> Place Jack in an upright position. a. Completely lower the Ram (13).<br><br> b. Remove the Filler Plug (16) and keep it clean. c.<br><br> Fill with high-quality hydraulic jack oil to the lower rim o5 the ll hole. d. Purge air 5rom the hydraulic system as previously described.<br><br> e. Top o55 with more hydraulic oil. 5.<br><br> Replace Filler Plug (16). g. t=o@-70>hoo?492 I5 the Jack 5ails to li5t, or 5ades under load, rst check that the Release Valve (4) is closed.<br><br> 1. Engage the notches at the end o5 the Jack Handle (45) onto the Release Valve (4) and turn clockwise. Check to see i5 this has solved the problem.<br><br> Next check to see i5 there are any leaks in the air system. Examine all connections and 2. valves to see i5 there is a leak.<br><br> I5 so, have a quali ed service technician repair the con- nection or replace the 5aulty part. Check to see i5 there are any leaks in the hydraulic system. Leaks will produce visible 3.<br><br> hydraulic fuid at the separation. I5 there are any leaks, have a quali ed repair technician tighten, repair or replace any leaking components. Air in the hydraulic system will cause the jack to 5ade.<br><br> I5 no leaks are detected, purge the 4. hydraulic system to remove any trapped air. Purging instructions are given in number 4, above.<br><br> The Air pump mechanism may be stuck. To remedy this, open the release valve, and 5. operate the air lever 5ully.<br><br> I5 none o5 these troubleshooting options solves the problem, it is possible that the seals o5 6. the jack have been damaged by overloading, dirt on the ram or other environmental 5ac- tors. Have a quali ed service technician inspect the Jack 5or 5aults and possible repair.<br><br> reV 070 SKU 95553 Fo= ?0.h94.a7 q@0>?4o9> ;70a>0 .a77 1-800-444-3353 .
