A, product introduction
HY78E type effortless wrench adopt effective planetary gear mechanisms as the main transmission, its characteristic is small volume, light weight, because of variable speed, smaller than the big input power can produce very big output torque. Product selection senior alloy and excellent heat treatment process, strong and durable. Surface is polishing pensu, has the good feeling. Widely used in disassembling of various types of load truck tyres, is auto mechanic necessary tools and broad driver friend ideal accessory tools.
Second, using method

1, will wind cannon sleeve into belt handle at output bystron, rocking bar to cover on the other end.
2, the wind cannon sleeve set to remove (into) the nut tightening firmness, shaking, pay attention to the direction that makes rely on hilt rocker close another bolt profile.
3 and when nut unscrew after long pole, change after fast disassembly. (when use first pick tighten rapidly tighten after long pole, reoccupy effortless wrench lock.

Three, technical parameters

1 and preach ratio 1:55. 7.
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.

Five and after-sales service

The products are sold, normal use cases, three months due to product quality for damage caused by the manufacturer is responsible. In abnormal use this tool to cause damage by customer responsible for replacement parts cost, manufacturer according to provide factory-gate prices.
