Tips
Do not start the tapper until positioning it against
the workpiece to be worked.
Use a suitable lubricant when tapping.
To avoid breakage of the tap, please observe the
following tips:
– Guide the tapper axial to the tap hole.
– Work with little feed.
– Pre-drill the tap hole with the correct diameter.
– Always work with sharp-edged tool inserts.
Tapping Through Holes
After reaching the desired thread depth, lightly
pull back the machine in order to reverse the di-
rection of rotation.
Use the depth stop 9 to prevent possible drilling
through. The tapper automatically switches to
left-hand rotation when reaching the set depth of
the hole.
Tapping Blind Holes
When tapping blind holes, spiral fluted taps are
used that automatically cause the chips to flow
out of the hole.
Use the depth stop 9 to prevent possible running
into and seizing of the tap.
Screwing-in Stud Bolts (see figure
For screwing-in stud bolts, the roller clutch 13,
the
chuck 11 must be mounted.
Depending on the thread diameter and the thread
reach, the stud bolts must be screwed in with a
respectively specified tightening torque.
Setting the Torque
The tightening torque can be adjusted between 3
and 10 Nm.
The knurled screw sleeve of the roller clutch 13 is
secured against self-acting displacement by
means of a spring clip.
Remove the spring clip with a screwdriver.
Turning the knurled collar anticlockwise reduces
the torque (3 Nm min.); turning clockwise in-
creases the torque (10 Nm max.).
After adjusting the torque, attach the spring clip to
the screw sleeve again.
When determining the best setting by practical
trial, it is recommended to begin with a low
torque.

Maintenance and Cleaning

Before any work on the machine itself, pull the
mains plug.
For safe and proper working, always keep the
machine and the ventilation slots clean.
If the machine should fail despite the care taken
in manufacturing and testing procedures, repair
should be carried out by an authorized after-sales
service agent for Bosch power tools.
In all correspondence and spare parts orders,
please always include the 10-digit article number
given on the nameplate of the machine.
WARNING! Important instructions for con-
necting a new 3-pin plug to the 2-wire cable.
The wires in the cable are coloured according to
the following code:
live = brown
neutral = blue
Do not connect the blue or brown wire to the
earth terminal of the plug.
Important: If for any reason the moulded plug is
removed from the cable of this machine, it must
be disposed of safely.
