Description – purpose of use

The Fortum® torque wrench is intended for tightening bolt connections to a required torque value, that is set on the torque wrench – not, however, for loosening bolt connections for the purpose of determining the value to which the bolt con­nection is tightened.The wrench enables torque to be quickly and easily set using a rotating ring. The ergonomic plastic handle ensures a comfortable grip of the wrench. The torque wrench is not intended for determining the torque value as an verification measuring device.

ATTENTION

• In the event that the number on the small scale is not in a position market by the mark, it will not be possible to push in the pulled out part.

SETTING A VALUE OF 8.6 Nm (MODEL 4700214)
On model 4700214 the adjustment setting is similar to model 4700215.

1. Grasp the handle of the torque wrench with one hand and use the other to pull the lock for adjusting the value out in the direction of the padlock as shown in fig. 1, position 3.
2. Turn the handle so that the line on the main scale is at the value 7 and at the same time so the small scale is set to the value 0.
3. Then turn the handle to set the small scale to 1.6, however turn the handle in the direc-tion of the numerical sequence 0, 0.2, 0.4… 1.6 and not in the direction, 0, 1.8, 1.6, which would set the value 6.6 Nm.
4. Secure the set torque value by pushing in the pulled out part in the direction of the closed padlock as shown in fig. 1.

ATTENTION

In the event that the number on the small scale is not in a position market by the mark, it will not be possible to push in the pulled out part.

Putting on the tightening tool and setting the turning direction

1. Press the middle button on the head of the ratchet (fig. 3) and put the tightening tool („socket“) of the required size on to the drive square.
2. Set the turning direction of the drive square by using one hand to attach a socket to block the rotation of the drive square and then with the other hand turn the top part in the direction L-R according to the marked arrow (see fig. 4). If the rotation of the drive square is not blocked, it will not be possible to change the rotation direction of the drive square.

Method of work for the torque wrench

Put the socket (tightening tool) on to the bolt head and start tightening the bolt connection. Slowly move the wrench in the range of 15°, and when tightening, increase the force gradually and carefully until the set tightening torque is reached. When the set torque value is reached, do not apply any further force on to the torque wrench.

Achieving the set torque value
Model 4700214
On model 4700214, the set torque value has been reached when the handle deviates to the side on the articulated joint, which is located between the head of the torque wrench and the handle. Try out the achievement of the set torque value in advance on a suitable bolt connection.

Model 4700215
On model 4700215, the achievement of the set torque value is indicated audibly by multiple „clicks“ (different than on model 4700214).Try out the achievement of the set torque value in advance on a suitable bolt connection.

Attention

• In the event that it is not possible to use standard socket tools („sockets“) on the wrench, it is possible to use other tightening attachments. However, using attachments leads to a lengthening of the wrench (lever), and thereby also to a change in the set torque value.
  The new torque N(A) can be determined using the following calculation: N(A)= N × [(A+B)/B]

Attention

• Use the torque wrench at a temperature in the range from +18 to 28°C (EN ISO 6789-1). Using the wrench outside of this temperature range may lead to a reduction in accuracy due to a change in the physical properties of the materials of the wrench, which change with temperature.
• After finishing work with the torque wrench, set a low torque value at the start of the scale so that the spring of the adjustment mechanism is not exposed to a long-term load during storage. This will prevent inaccuracies in the torque settings resulting from „fatigue“ of the spring.
• If the torque wrench is not used regularly, we recommend to first perform a cycle of tightening a threaded joint at a low torque several times before using it.

Attention

• To maintain measurement accuracy, we recommend to have the torque wrench regularly
  calibrated at a laboratory that has accreditation for the calibration of torque tools.
  Calibration is performed on a special device and every user must have it performed at their own cost for a fee. The calibration is not provided by the manufacturer or the supplier and it is not covered by the warranty conditions since this is not a product defect from the factory.

• It is appropriate to perform a calibration:

• If the wrench has been used more than 5000 ×

• After it has fallen or after an inappropriate method of use

• If the wrench has not been used for a long time

Information about inappropriate handling of the torque wrench

Attention
Inappropriate use may cause damage to the torque wrench, for which it is not possible to exercise a claim for free warranty repairs and may negatively affect its accuracy.

Attention

• The torque wrench does not require any addition of lubricants, do not tamper with the internal parts of the torque wrench and do not disassemble the torque wrench. Prevent the torque wrench from coming into contact with water, oil and other liquids. For the purpose of cleaning the torque wrench, only use a clean dry textile. Do not use any degreasing agents on plastic parts of the torque wrench since this would damage the plastic.
• Do not overload the torque wrench.
• Do not modify the torque wrench in any way.
• If necessary, have it repaired at an authorised service centre for the Fortum® brand.
