Impact Wrench
-
Left rotation:
Push the rotational direction switch all the
way to the left.
Switching on/off
To start, press the on/off switch and keep it
pressed.
To switch off, release the on/off switch.
Adjusting the Speed
You can adjust the speed of the power tool
when it is on by pressing in the on/off switch
to varying extents.
A light pressure on the on/off switch results in
a low rotational speed. Increased pressure on
the switch causes an increase in speed.
Preselecting speed
You can preselect the required speed using
the speed preselection thumbwheel.
Practical advice
►Pull the plug out of the socket before
carrying out any work on the power
tool.
►Only apply the power tool to the screw/
nut when the tool is switched off. Rotat-
ing 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. Maximum torque is achieved
after an impact duration of 3–5 seconds.
After this duration, the tightening torque is in-
creased only minimally.
Instead, the gearbox housing noticeably heats
up.
Note: The consequences of excessive heat-
ing include increased wear on all parts of the
impact mechanism and a high need for lubri-
cant.
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.
A torque characteristic depends on the follow-
ing factors:
-
Strength of nuts
-
Type of backing (washer, disc spring, seal)
-
Strength properties of the material being
screwed/bolted together
-
Lubrication conditions at the screw/bolt
connection
Maintenance and Service
Maintenance and Cleaning
►Before any work on the machine itself,
pull the mains plug.
►For safe and proper working, always

Note
Technical errors and typographical errors
may be made in the text and numerical
designations of the instructions.
Since the product is constantly being
improved, P.I.T. reserves the right to make
changes to the specifications and product
specifications specified here without prior
notice.
Changing the Tool
►Pull the plug out of the socket before
carrying out any work on the power
tool.
►When working with an application tool,
pay attention that the application tool is
connected securely to the tool holder.
If the application tool is not securely con-
nected to the tool holder, it may become
loose and can no longer be controlled.
-
Slide the application tool onto the square
drive of the tool holder.
Note! The product is equipped with a nozzle
lock, which holds the nozzle during operation
and carrying. For removal / installation, a cer-
tain amount of force is required.
Operation
Method of Operation
The tool holder(with the application tool) is
driven by an electric motor via a gear and im-
pact mechanism.
The working procedure is divided into two
phases:
Screwing in and tightening (impact mecha-
nism in action).
The impact mechanism is activated as soon
as the screwed connection runs tight.
In this instance, the impact mechanism con-
verts the power of the motor to steady rotary
impacts. When loosening screws or nuts, the
process is reversed.
Starting Operation
►Pay attention to the mains voltage.
The voltage of the power source must
match the voltage specified on the rat-
ing plate of the power tool.
Setting the Rotational Direction (see figure
A)
The rotational direction switch is used to
change the rotational direction of the power
tool. However, this is not possible while the
on/off switch is being pressed.
-
Right rotation:
Push the rotational direction switch all the
way to the right.
