Please keep this manual for future reference.
 Don’t use the angle torque wrench beyond the maximum torque setting. This will cause damage or
injury.
 Don’t drop the angle torque wrench or apply a strong shock or jolt. This will cause damage or
deformation as well as decrease the accuracy and durability, which may cause an accident or injury.
 Don’t use this angle torque wrench except for tightening purpose. This is a angle torque wrench for
bolt tightening only.
 Don’t expose the angle torque wrench to water or oil. It will result in a possible breakdown or
cause damage.
 Remove any dirt such as dust, mud, oil and water, etc. after each use and before storing the angle
torque wrench.

using the ANGELE TORQUE WRENCH.
 Handle with care when using the ANGLE TORQUE WRENCH. The wrench is a measuring tool.
 Set the torque within the torque range.
3. OUT LINE

1) Set the desired snug torque.
2) Connect the flexible tube to the pointer adapter and fix the clip to the work piece or the bolt nearby.
3) Engage the socket with a bolt.
4) To preset angle:
Set the pointer to the desired angle and start tightening. After the snug torque is reached, the angle scale
starts moving. Tighten the bolt until the angle scale reads zero degree.
5) To read angle:
Set the pointer to zero degree on the angle scale. After the snug torque is reached, the angle scale starts
moving. Tighten the bolt until the desired torque is reached.
6) To use the wrench as an ordinary torque wrench:
Remove the flexible tube from the pointer adapter and set the desired torque. Tighten the bolt until a
“click”is heard.
7) To attach a magnet base:
Remove the nut that fixes the clip and flexible tube. Insert the top screw (M8X1.25) of the flexible tube
into the screw hole in the magnetic base and tighten.
Note: Recommended magnetic base is Kanetsu MB-PB or Fuji Jiko BR-50.
