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 specifi ed on the rat-
ing plate of the power tool.
Switching on the product (fi g. A)
The product is switched on by pressing the
button of the three-position switch. Depending
on the required direction of rotation (twisting /
unscrewing), press the corresponding part of
the button:
► The upper part (R) - for unscrewing (coun-
terclockwise);
► The lower part (F) - for twisting (clockwise).
NOTE!
When tightening, do not turn off the
product immediately when the fastener rests
on the part; when unscrewing, wait at least
the specifi ed time before unscrewing.
The product has a high torque. Always hold it
FIRMLY with both hands when working.
Switching off the tool
During breaks or at the end of work, turn off
the product by releasing the key.
During intensive work, the gearbox housing
and wrench heats up.
Do not touch them immediately after fi nishing
work and until they have completely cooled
down.
Release the switch to stop the tool.
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
keep the machine and ventilation slots
clean.
►
A damaged dust protection cap should
be changed immediately. We recom-
mend having this carried out by an af-
tersales service.
When the battery is no longer operative,
please refer to an authorised after-sales ser-
vice agent for P.I.T. power tools.
