4.1. TECHNICAL REMARKS

In order to achieve a constant and accurate repetition of the cut-off points, the bolt must be tightened in

one go without interruption of the procedure from the motor start until the wrench reaches its cut off

setting. Before increasing the torque, the rated speed must be reached. The tool speed when running idle

is in accordance with the selected torque.

During certain tightening procedures, for example, if bolts are already tightened, and are tightened

further, the motor will become very hot. Should this happen, let the motor run idle, so that the air flow

can cool down the motor to its normal operating temperature.

This will prevent overheating and damage to the motor!

Should the warning lamp (10) is flash, stop work immediately and proceed as described above

If the tightening procedure is stopped before the cut off setting is reached, this bolt must be loosened

again, and the tightening procedure repeated!

A bolt which has already been tightened to the required torque must not be tightened again with the

same torque. This will lead to excess torque being applied.

At normal operating temperature and with constant mains voltage, the accuracy of repetition of the cut-off

points lies within a tolerance of +/-5%. The calibrated torque values at the different settings are for a bolts

with a short length of grip. Bolted connections of other types can result in a different torques being

achieved.

In general - when making bolted connections - observe the instructions of the manufacturers or the

directions of the engineering specifications in the first place.

Wrench has no torque capacity.

The power frequency is different from the value prescribed by the machine label, or

the wrench is connected to an inappropriate power supply.

Wrench does not start after operating the Right/Left-Switch (5)

nor after a repeated pressing of the On/Off-Switch (4)

The electronic restart protection allows a restart only after a delay of approx. 3 seconds, this is

necessary to prevent a restart of gear parts which are still in motion.

Unusual bolting performance

(Hard and soft bolting jobs excluded)

Within the area of radar radiation (or similar), it is necessary to provide an equi-potential bonding,

and the torque applied must be checked.
