7.5 Set the torque via the setting wheel

The speed and the tightening torque are directly correlated. The lower the speed, the lower the tightening torque.

- Set the tightening torque with the setting wheel 5 (see Fig. 1).

Various tightening torques can be set by means of the speed levels 1-6. Speed level 1 equals a low tightening torque and speed level 6 the maximum tightening torque. In addition, intermediate levels are available.

Carry out a test screwing to determine the correct speed setting.

7.6 Set the torque with the switch trigger

The speed can be continuously adjusted by pressing in the switch trigger to varying degrees, thus adapting it to the material and the working conditions.

- Increase or decrease the speed by changing the depth to which the switch trigger 2 is depressed.

7.7 Automatic speed adjustment ASC

Speed level ASC (Automatic Speed Control) is equipped with an automatic speed adjustment.

Speed adjustment when loosening: Prevents the screw / nut from falling by automatically reducing the speed after loosening.

Speed adjustment when screwing home: Prevents an overtightening of the screw / nut by automatically switching off the machine after the first impact.

7.8 Tool change

Risk of burns

The tool can be very hot after working. Touching the tool can cause skin burns. Allow the tool to cool down before changing it.

Only use high-grade tools, which are suitable for the forces and torques occurring! Broken tools will lead to a machine defect. If repairs are necessary, contact the customer service stations for MAFELL electrical tools.

8.6 Work instructions

Risk of burns

Working with the machine for a prolonged period of time can cause the gearbox housing to get very hot. There is a risk of burns! Allow a hot gearbox housing to cool down

The wrenching process of the impact wrench consists of screwing in a screw / nut by means of the tool's rotary motion and tightening a screw / nut by means of the impact mechanism.

The tightening torque depends on the impact duration. The torque curve depends on the application. Take into consideration the possible applications:

Application "Hard screw application":

When screwing into hard material, such as metal or concrete, the maximum tightening torque is already reached after a short impact duration (approx. 5 s).

Application "Soft screw application":

When screwing into soft material, such as wood, a longer impact duration is required.

Follow the procedure below when working with the machine:

• Place the machine onto the screw / nut when it is switched off.
• While working with the machine, keep it directed straight at the screw / nut.
• Set the tightening torque either by adjusting the setting wheel or by pressing in the switch trigger 2 in such a way that the screw / nut is not damaged or the screw head is not torn off.

With small screws / nuts, the maximum tightening torque is already reached after less than 0.5 seconds impact duration.

- Determine the correct impact duration by means of test screwing.
