When working with an application tool, pay
attention that the application tool is connected
securely on the tool holder. When the application
tool is not securely connected with the tool holder, it can
come off during application.
Slide the application tool 16 onto the square drive of the tool
holder 1.
With this system, there will be a slight amount of play around
the application tool 16 after connecting securely to the tool
holder 1; this has no influence on the function/safety.
Some application tools (e. g. double bits) cannot be safely
secured in the tool holder.
Method of Operation
The tool holder 1 with the tool is driven by an electric motor
via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in and tightening (impact mechanism in
action).
The impact mechanism is activated as soon as the screwed
connection runs tight and thus load is put on the motor. In this
instance, the impact mechanism converts the power of the
motor to steady rotary impacts. When loosening screws or
nuts, the process is reversed.
Starting Operation
Inserting the Battery
Use only original Würth lithium-ion batteries
with the voltage listed on the nameplate of
your power tool. Using other batteries can lead to
injuries and pose a fire hazard.
Set the rotational direction switch 9 to the centre position to
protect the power tool against accidental starting.
Insert the charged battery 4 from the front into the base of the
power tool until the battery is securely locked.
Reversing the Rotational Direction
(see figure B)
The rotational direction switch 9 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 10 actuated.
Right rotation: For driving in screws and tightening nuts,
press the rotational direction switch 9 through to the left stop.
Left Rotation: For loosening and unscrewing screws and
nuts, press the rotational direction switch 9 through to the right
stop.
Switching On and Off
To start the machine, press the On/Off switch 10 and keep
it pressed.
To switch off the machine, release the On/Off switch 10.
To save energy, only switch the power tool on when using it.
Adjusting the Speed
The speed of the switched-on power tool can be variably
adjusted, depending on how far the On/Off switch 10 is
pressed.
Light pressure on the On/Off switch 10 results in a low rota-
tional speed. Further pressure on the switch results in an
increase in speed.
Preselecting the Speed/Impact Rate
With the button 6 you can preselect the required
speed/impact rate in three stages. Press the button 6 repeat-
edly until the desired setting appears in the speed indicator 7.
The selected setting will be saved.
The required speed/impact rate depends on the material and
the working conditions, and can be determined through prac-
tical testing.
Switching the "PowerLight" On/Off
To switch the "PowerLight" 11 on, press button 8. To switch
the "PowerLight" 11 off, press button 8 again.
Working Advice
Apply the power tool to the screw/nut only
when it is switched off. Rotating tool inserts can slip
off.
The torque depends on the impact duration. The maximum
achieved torque results from the sum of all individual torques
achieved through impact. The maximum torque is achieved
after an impact duration of 6–10 seconds. After this duration,
the tightening torque is increased only minimally.
The impact duration is to be determined for each required
tightening torque. The actually achieved tightening torque is
always to be checked with a torque wrench.
Screw Applications with Hard,
Spring-loaded or Soft Seat
A test in which the achieved torques in an impact series are
measured and transferred to a diagram will produce the
curve of a torque characteristic. The height of the curve corre-
sponds with the maximum reachable torque, and the steep-
ness indicates the duration in which this is achieved.
