instructionmanual the steel jack is designed by mechanical transmission principle.it’s one of the best lift tools used in repairing, etc. the liftingor lowering speed is controllable. moreover, it overcomes theshortcoming of the common hydraulic jacks whose lowering height andspeed is out of control when oil leaking. the top- all steel structure makes it safe and durable, thecompact design with collapsible lever offers easy operation andsimple maintenance. it has two applicable support stands. thelifting range is much bigger. operation guide put the steel jack on even places. then place the goods on thelower support stand (4) or the upper support stand (3). shake thelevel (2) clockwise to lift the goods, vice verse, the goods arelowered down. (1) base (2) level (3) upper support stand (4) lower support stand (5) upper ratchet pawl (6) lower ratchet pawl (7) axle ring
attention a. do not exceed the rated capacity. overload is forbidden. b. before operation, please check the flexibility of the ratchetpawls (5), (6) c. please be sure the jack is on complete balance when operating.do not put it on beveled, arc or uneven surfaces. the jack must beplaced on hard plain grounds. d. before lifting, please be sure the support stand (4) (3)supports the goods completely. e. when several jacks are used at the same time, please be sure ofthe same lift or down. the whole operation course should bedirected. f. it’s forbidden putting any parts of the body under the liftedgoods. g. if working force is abnormal in operation, please stop workingimmediately to inspect all related transmit components. h. lubricate parts applicably regularly.
i. the uppersupport stand (3) should be on bottom position when the jack is notused.
