2, maximum output torque 4200N. J M j M 420KGF equivalent.
3, normal remove (fastening) needed for maximum output torque nuts 2500N. J M, (equivalent to 3 meters strength stem use 85 kilograms force) for 20 kilograms force rocker pull force.
4, remove (fastening) a tyre needed time about six minutes.
5, tools, net weight 6.2 kilograms, weight 7 kilograms.

Four, the matters needing attention

1 and strength of not more than 20 kilograms, it may be damaged nuts or this product components.
2 will not cylinder as hammering tools use.
3, don't add hand lever rod sets or pry bar after strength.
4, disassembled note nut tightness direction, if use a greater force and cannot make nuts, become loose, judge the whether it will be shaken out reverse direction.
