labor saving wrench

4.Special remander: If a greater force is used but the nut will not be unscrewed,make sure that the direction of the nut and that of the rocking bar are correct.

3.Do not add force to the rocking bar by using loop bar or hand bar.

2.Do not use this tool as a hammer.

1.Tightening nuts by using Model A ,dont use force more than 20kg.When half-round rebound of the rocking bar is felt. It shows that the nut has come to the place. The overforce is likely to damage the nut or the tools.

Cautions

5.The net weight of the tool is 7.4 kg and the total weight is 8.5kg.

4.It takes about six minutes to disassemble(tighten) a tyre.

3.Max output torque for normal dissembling(tightening) is 1200N.M(equal to 40 Kgfapplied to 3-meter-long bar)and the pull force of rocking bar is 18kgf.

2.Max safe output torque is 3800N.M(equal to 380 KGF.M)

1.Gear ratio 1:55.6

Technical parameter

3.After the nut is unscrewed ,use the long bar to disassemble quickly.(First use the long bar to screw on quickly and then use labour saving wrench instead during tightening.)

2.When the sleeve is put on the net to be disassembled or fastened ,pay attention to the direction of loosening an tightening . Roll the rocking bar so that the handle is against the side of another bolt tightly.

1.put the sleeve onto the square head of the handle end and the rocking bar on the other end
