Mains cable module
Mains cable module with Patent
Quick Interlock.
Connect the mains cable module 4 to the handle.
The plug must snap in.
Use the mains cable module 4 only for Kress pow-
er tools. Do not attempt to operate other machines
with the module.
Damaged mains cable modules must not be used.
They must be replaced by a new Kress mains ca-
ble module immediately.
Push the two unlocking buttons VIII and remove
the mains cable module 4 from the handle.
Use only original Kress mains cable modules.
Safety friction clutch (Option)
To limit dangerous reaction torques,
the machine is equipped with a safety
friction clutch.
Always assume a safe standing position and hold
the power tool securely in both hands.
When the drill becomes wedged unexpectedly,
the power tool jerks.
If the drilling tool clamps or hooks,
the drive to the drill spindle is inter-
rupted and the noise of the overlock-
ing coupling can be heard.
Remove the load from the machine
immediately by retracting the drill.
Switch off the power tool and loosen the drilling
tool if the power tool is blocked.
When switching on the machine with a jammed
drilling tool, high reaction moments can occur.

Operation
On/off
Press or release the On/Off switch VI. The On/Off
switch VI can be stopped with the stop button V.
Release the On/Off switch VI by pressing and re-
leasing briefly.
Make sure that the machine is not
blocked longer than 2-3 seconds.
The motor can get damaged if
blocked longer.
Preselect speed (Option)
In devices with a setting dial VII, you can select
the speed using the setting dial VII depending on
the area of application.
Position "A" = lowest speed
Position "G" = highest speed
or
= lowest speed
= highest speed
Change speed
The On/Off switch VI can be used for infinitely var-
iable speed control. Light pressure on the On/Off
switch VI causes the machine to rotate slowly;
with increased pressure, the speed increases.
The motor can become overheated in
case of continuous high load and low
speeds. Allow motor to cool off at
high speed in idle run.
Mechanical gear selection (option)
With the gear selector switch III you can preselect
two speed ranges.
1 Low speed range, high torque; for
drilling, fixing screws and thread cut-
ting.
2 High speed range; for drilling and
percussion drilling.
The changeover must be done when
the machine is running slowly.
