OPERA TING PRINCIPLES ⢠W i t h r e l e a s e v a l v e c l o s e d , a n u p w a r d stroke of the ja ck handle draws oil from the reservoir tank into the plunger cavity . Hydraulic pressure holds a valve closed, which keeps the oil in the plunger cavity . ⢠A d o w n w a r d s t r o k e o f th e j a c k h a n d l e releases oil into the cylinder , which forces the ram out. This raise s the sadd le . (NOTE : T o avoid damage to the cylinder if the load ex ce ed s th e ra te d c ap ac it y of t h e ja ck , o i l i s a u t o m a t i c a l l y r e l e a s e d b a c k i n t o the reservoir through the safety overload valve.) ⢠Wh en th e ram re ac hes ma xi mum ex te nsi on, oil is bypassed back into the reservoir to prevent an over-extended ram stroke and possible damage to the jack. ⢠Op eni ng t he r el ea se v alv e al lo ws o il to ï¬ow back into the reservoir . This releases h y d r a u l i c p r e s s u r e o n t h e r a m , w h i c h results in lowering the saddle. No t e : T h e re l e a se v a l ve m u s t b e cl o s e d for the handle to remain upright. When the re l ea s e va l ve is o p en e d, th e h an d le ma y lower to the ï¬oor . HOW TO USE YOUR JACK RAISING THE JACK ⢠Chock the vehicle wheels with appropriate dev ic es to pre ve nt veh ic le fro m movi ng and to ensure lifting stability . ⢠Close the release valve by turning the jack handle clockwise until tight (Fig. 4). ⢠Re fe r to the vehi cl e ma nuf ac tu re râs own er â s manual to locate approved lifting points on the vehicl e. Positio n jack so that the saddle (Fig. 4) is centered under the load at an appropriate lift point. ⢠Pump jack handle until saddle ALMOST contacts the vehicle. Check to see that the saddl e is cente red and will contact the load lifting point ï¬rmly . ⢠Continue to pump the jack handle to lift th e ve h i c l e t o t h e de s i re d h ei g h t . Af te r lifting, immediately support the load with appropriately rated vehicle support stands BEFORE working on the vehicle. OPERA TION LOWERING THE JACK ⢠S L O W LY o p e n t h e r e l e a s e v a l v e b y t u r n i n g t h e h a n d l e c o u n t e r c l o c k w i s e , b u t n e v e r m o r e t h a n 1 / 2 f u l l t u r n a t a time.

Use a matched pair of jack st an ds p er v eh ic le t o su pp or t on e en d only . Use 1 pair per vehicle only. Failure to do so may result in sudden loss of load, which may cause personal injury and/or property damage. LOWERING THE JACK Warning: T o avoid crushing injuries and property damage: Keep hands and feet clear of work area when lowering load. ⢠Raise load high enough to clear the jack stands, then carefully remove jack stands ( always used in pairs). ⢠SLO WL Y open the releas e valve by turni ng th e ha nd le cou nt e rc lo ck wi se , bu t n ev er more than 1/2 full turn. If the load fails to lower: ⢠Use anoth er jac k to rais e the veh icl e high enough to reinstall jack stands. ⢠Remove the affected jack and then the stands ⢠Using the other jack, lower the load by tur ni ng t he op er at in g han dl e cou nt er- c l o c k w i s e , b u t no m o r e t h a n 1 / 2 f u l l turn. ⢠A f t e r r e m o v i n g j a c k f r o m u n d e r t h e l o a d , p u s h s a d d l e d o w n t o r e d u c e r a m exposure to rust and contamination. ! ! 5

DO NOT use Hydraulic Brake Fluid, Alcohol, Glycerine, Detergent, Motor Oil or dirty oil. Use of an improper ï¬uid can cause serious int ern al dam age to your jack. W e reco mme nd Mobil DTE13M or equivalent. ADDING OIL ⢠Position the jack on level ground and fully lower the saddle. (Ram will be all the way in). Remove oil ï¬ller plug from the reservoi r (see Fig. 4 & 5). ⢠Oil should be ï¬ll ed to the level of about 3/ 16 â a bo ve th e in ne r c yl i nd er as s ee n from the oi l ï¬ll er ho le. If low , add oil as needed. ⢠Re-in stall oil ï¬ller plug. The jack is now ready to use. LUBRICA TION ⢠Add lubricating oil to all moving parts as needed. PREVENTING RUST ⢠C h e c k r a m an d p u m p p l u n g e r ( F i g . 5 ) every few months for any signs of rust or corrosion. Clean as needed by wiping with an oily cloth. ⢠When not in use, AL WA YS store jack with saddle lowered all the way down.
