INFORMATION ABOUT THE BATTERY
The battery is equipped with protection
against full discharge, which damages it. This
protection manifests its self by the power tool
coming to a sudden stop even when the trigger switch is
pressed, when the battery has been discharged multiple
times. When the trigger switch is released and then
pressed again, the power tool will start again for a short
time, but then it will stop running again.
VII. General safety
instructions for power tools
•
WARNING!
It is necessary to read all the safety instructions,
the user‘s manual, images and regulations supp-
lied with this power tool.
Not adhering to any of the
following instructions may lead to injury by electrical shock,
a fire and/or a serious injury to persons.
All the instructions and the user‘s manual must be
kept for possible future reference.
The term „power tool“ in all hereafter provided warnings is defi-
ned as an tool powered from the power grid (via a power cord) or
a tool powered from a battery (without a power cord / cordless).
1) SAFETY IN THE WORK AREA
a)
The work area needs to be kept clean, tidy,
and well lit.
Untidiness and dark areas in the work
area are sources of accidents.
b)
The power tool must not be used in environ-
ments where there is an explosion hazard,
where there are flammable liquids, gases or
dust.
The power tool generates sparks which could
ignite dust or vapours.
c)
When using the power tool, it is necessary to
prevent children and other persons access.
If the user becomes distracted, they may lose control
over the activity being performed.
e) After charging, first disconnect the charger
from the el. power source
and then, after pressing
and holding down the button on the battery, slide the
battery out of the grooves in the charger.
V. Preparing the impact
wrench for use
ATTACHING/REMOVING A TOOL
FROM THE TANG OF THE IMPACT WRENCH
y
Put a tool intended for a 1/2“ square tang with the
required size on to the tang so that it clicks in.
y
Remove the tool from the tang by hand, by pulling
along the axis of the tang.
SETTING ROTATION DIRECTION
y
For the tightening mode, fully push down the rotation toggle
switch (fig. 1, position 8) on the right side of the impact wrench.
y
For the loosening mode, fully push down the rotation toggle
switch (fig. 1, position 8) on the left side of the impact wrench.
•
ATTENTION
y
If the workpiece is not sufficiently stable with its own weight
or character, for safety reasons, always secure it in advance.
INSERTING THE BATTERY
INTO THE HANDLE OF THE IMPACT WRENCH
y
Slide the battery into the handle of the impact wrench
so that it clicks into place, see fig. 1.
VI. Using the impact wrench
y
Put the tool seated on the tang of the impact wrench
on to the head of a bolt or nut and then appropriately
pull on the trigger of the impact wrench relative to the
rotation speed of the tang. The rotation speed of the
tang is proportionate to the degree to which the trigger
is pulled.
•
ATTENTION
y
Always ensure that the bolt head or nut is well seated in
the tool before starting the impact wrench. Attempting
to seat the tool on to the bolt head or nut while the
impact wrench is running or if the tool is incorrectly sea-
ted on the bolt head or nut may cause it to slip and result
in a sudden loss of control over the impact wrench.
y
When working with the impact wrench, hold it firmly
by the handle since during tightening or loosening,
high reaction torques may be generated.
y
The work activity of the impact wrench can be
divided into the screwdriver mode and the tigh-
tening and loosening mode.
As soon as the tightening of threaded connection phase
starts (higher load on the motor), the impact wrench swit-
ches from the screwdriver mode to the tightening mode,
where the impact mechanism raises the torque by means
of regular hits. The impact mechanism acts in the direction
of rotation.
When loosening threaded connections, these work
processes go in reverse sequence.
After reaching the nominal load, the impact
mechanism disengages from activity.
y
Torque depends on the impact time.
Maximum torque is the result of the sum of the individu-
al partial, by means of impact achieved, torques.
Maximum torque is achieved when the impact time is
3-5 seconds, thereafter torque increases only marginally.
•
ATTENTION
y
When the impact time exceeds 5 seconds, the
gearbox heats up significantly and parts of the
impact mechanism are worn out more!
y
The necessary impact time for achieving the required
torque is found by determined by checking the current-
ly achieved torque values per given time. Determine the
achieved torque level using a torque wrench.
y
To dampen vibrations, we recommend working in
thicker gloves.
y
Wait until the tool tang comes to a complete stop befo-
re putting down the impact wrench.
y
Never carry the impact wrench when it is running. Wait
until the tang stops rotating.
•
ATTENTION
y
When not using the impact wrench, set the rotation
toggle switch to the middle position to secure the trigger
against accidental pressing (starting the cordless power
tool).
