[SS10-30, SS10-36, SS21-45]
• When mounting, install additional handle 5 and
screw in bolts 10 with the help of allen key 6, as shown
in figure 2.
• Disassembly operations do in reverse sequence�
Socket wrench mounting / dismounting (see
fig. 3)
• While mounting, install the socket wrench 8 on the
tool holder 1 as shown on the figure 3.
• Disassembly operations do in reverse sequence�
Initial operating
of the power tool
Always use the correct supply voltage: The power sup-
ply voltage must match the information quoted on the
power tool identification plate.
Switching the power
tool on / off
Rotation to the right
Press and hold the on / off switch 4 on the bottom ("F",
see fig. 4.1), to switch off - release it.
Rotation to the left
Press and hold the on / off switch 4 on the top ("R", see
fig. 4.2), to switch off - release it.
Change the direction of rotation only
after a full stop of the motor, acting
otherwise may cause damage to the
power tool.
Design features
of the power tool
The tool holder 1 with the socket wrench 8 is driven
by an electric motor via a gear and impact mecha-
nism�
The working procedure is divided into two phases:
Screwing in and tightening (impact mechanism in ac-
tion)� The impact mechanism is activated as soon as
the screwed connection runs tight and thus load is
put on the motor, converting the power of the motor
to steady rotary impacts� When loosening screws or
nuts, the process is reversed�
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 dura-
tion of 3-5 seconds� After this duration, the tighten-
ing torque is increased only minimally� However, the
transmission housingheats up noticeably�
The consequences of excessive heating-
up are high wear of all hammer mecha-
nism components and a high require-
ment of lubricant.
The impact duration is to be determined for each re-
quired tightening torque� The actually achieved tight-
ening torque is always to be checked with a torque
wrench�
on the power tool operation
Apply the socket wrench to the tool holder
only when the power tool it is switched off.
A torque depends on the following factors:
• Strength properties of the screws / nuts�
• Type of backing (washer, disc spring, seal)�
• Strength properties of the material being screwed /
bolted together�
• Lubrication conditions at the screw / bolt connec-
tion�
Hard seat - is given for metal-to-metal screw applications
with the use of washers� After a relatively short impact
duration, the maximum torque is reached� Unnecessary
long impact duration only causes damage to the ma-
chine�
Spring-loaded seat - is given for metal-to-metal screw
applications, however with the use of spring washers,
disc springs, studs or screws / nuts with conical seat as
well as when using extensions�
Soft seat - is given for screw applications, e� g�, metal
on wood or when using lead washers or fibre washers
as backing�
For a spring-loaded seat as well as for a soft seat, the
maximum tightening torque is lower than for a hard
seat� Also, a clearly longer impact duration is required�
The impact duration is to be determined through practi-
cal testing�
At temperatures below the freezing point, run the ma-
chine for approximately 3 minutes at no-load to im-
prove its lubricating capacity�
Power tool maintenance /
preventive measures
Before carrying out any works on the power tool
it must be disconnected from the mains.
Cleaning of the power tool
An indispensable condition for a safe long-term exploi-
tation of the power tool is to keep it clean� Regularly
flush the power tool with compressed air thought the
ventilation slots 3�
