Function Meaning
Cutting
In mode, when the control switch is pressed and held down the product cycles
through one complete cycle. The cycle consists of 2 phases:
1. Perform cutting operation
2. Return to initial position
After completing a cycle the product stops automatically and the control switch has to
be pressed again to start a new cycle.
You can pause a cycle at any time by releasing the control switch. Pressing the control
switch again resumes the phase in which you released the control switch.
Lock (middle position)
The movable cutting arm is locked and cannot be moved. Select this function when you
are not working with the product.
Reverse
When the control switch is pressed the movable cutting arm opens.
Use this function only if you have to release a threaded rod while a cut is in progress, for
example because the thread of the threaded rod is not correctly seated in the thread of
the cutting edges or the product's overload protection coupling has tripped.

4.3 Noise information and vibration values in accordance with EN 62841
The sound pressure and vibration values given in these instructions were measured in accordance with a
standardized test and can be used to compare one power tool with another. They can also be used for a
preliminary assessment of exposure.
The data given represent the main applications of the power tool. However, if the power tool is used for
different applications, with different accessory tools, or is poorly maintained, the data can vary. This can
significantly increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times when the tool is switched off, or
when it is running but not actually being used for a job. This can significantly reduce exposure over the total
working period.
Identify additional safety measures to protect the operator from the effects of noise and/or vibration, for
example: maintaining the power tool and accessory tools, keeping the hands warm, organization of work
patterns.
