Part Name

Before Use

Confirm required torque value for the bolt/nut to be tightened. If torque value is not given, contact bolt manufactures or calculate it with referring the formula below.

• T: Tightening Torque (N·m)
• K: Torque Coefficient
• D: Bolt Diameter (m)
• N: Bolt Tension (kN)

Operating Procedure

1. Insert sockets to the square drive of the torque wrench completely.
2. Confirm the position of Reverse Lever as shown in the figures below.
3. Torque Setting
   • Turn the locking screw in a counterclockwise direction until it hits the Pin.
   • Set target torque with adjusting torque setting knob.
   • The target torque is visible at graduation.

Turning the torque setting knob in a clockwise direction gradually becomes hard as the maximum torque approaches. In this case, according to the right side drawing, turning the torque setting knob and a body case as well make it much easier to set the target torque. In case of turning the torque setting knob at out of specified torque range, the torque setting mechanism becomes to be stuck and breakdown.

Torque Setting example by T4MN200R

• In case of setting the target torque from 40N · m to 92N · m, keep turning the torque setting knob in a “clockwise direction” until the value is visible.
• In case of setting target toroue from 200N · m to 126N · m, keep turning the toroue setting knob in a “counterclockwise direction” until the value is visible.
• Turn the locking screws in a clockwise direction and lock it.
  • The torque setting is completed.

1. Slide the socket over the bolts and nuts to be tightened.
2. Grip at loading point and turn the torque wrench in a clockwise direction slowly.
3. When reaching preset torque, the wrench makes a clicking sound as well as a light retroaction. Immediately stop applying torque when click sound is heard. Further tightening will end up with over torque.

CAUTION

• Apply torque slowly. Never apply torque with quick motion or put weight on the torque wrench.
• Failure to follow this instruction may result in imprecise torque accuracy, malfunction of the wrench, and /or injury.
• Be aware that applying torque more than the preset torque may happen if the preset torque is low torque value. This is because a clicking sound or a light retroaction is hard to be detected.
• After using, set the torque value to the minimum and store the torque wrench in a designated place.
• Failure to follow this instruction may result in the deterioration of torque accuracy and durability of the torque wrench.

Operation in a Counterclockwise Direction

• This product is intended for use in both clockwise and counterclockwise direction. For operation in a counterclockwise direction, reinsert a socket in an upper side, and turn over the torque wrench as shown in below. Grip at loading point and turn the torque wrench in a counterclockwise direction. See also the operating procedure.

Repair & Maintenance

• The torque wrench needs to be repaired when the clicking sound and the light retroaction are lost.
• The precision of ±4% comes up to the standard after repair.
• Accuracy might become inaccurate in case that the torque wrench is not in use for a long time or is not used properly. Contact your distributor periodically for maintenance to keep the accuracy of the torque wrench.
• Carry out overhaul once a year or l 00,000 tightening, whichever comes first.
• Contact your distributor for details of handling the torque wrench.

Expiry Date of the Calibration Certificate

1. When not in use.
   • The calibration certificate expires 3 years from the date of calibration.
2. When coming into use less than 3 years from the date of calibration on the calibration certificate.
   • The calibration certificate expires l year from the date of coming into use, or up to l 00,000 tightening that is mentioned in “Repair and Maintenance· section.

Specifications

• Accuracy: +/-3%
• Load Direction: Clockwise Direction only

Specifications may be changed without notice.
Modification of the instruction manual will be substituted for the notice.
