Screwing
Make sure that the bit and screw correspond in size
and shape.
It is advisable to use socket-head screws since their
self-centering action ensures safe work. Or even
better – TORX screws and the corresponding bits.
Optimal screwing is achieved when the screwing
device is fixed securely in the screw head.
Depth stop
The adjustment of the screwing depth takes place with
the adjustment ring (3).
1 Revolution = 1.4 mm
Turning to the right:
The screw is set deeper.
Turning to the left:
The screw is set less deep.
To determine the screw depth, it is recommended to
begin with a low depth setting and readjust to the final
depth.
Bit
To replace the bit, pull off the depth stop (1). The bit
can then be pulled from the bit holder and a new bit
inserted. Replace the depth stop (1).
Clutch
The screw can be placed on the still standing bit while
the machine is running. The clutch engages only after
applying pressure while screwing. When the depth
stop comes to rest on the surface, the clutch is disen-
gaged. The bit again comes to a stop.
Maintenance
The machine's motor has life-time lubrication and
requires no special maintenance. However, should
you operate the machine on a continuous basis over
long periods of time we recommend that you send us
the machine for thorough cleaning and an inspection.
This will spare you unnecess-ary repair expenses and
increase the machine's service life. If you always
clean the ventilator of dust after each operation, the
motor will enjoy an ever longer service life. Uniform
ventilation is essential for a long service life.
Replacing carbon brushes
Our service personnel will do this and all other servic-
ing work fast and professionally.
Damaged mains cables should not be used. They are
to be replaced without delay.
As the result of a innovative mains cable module (6),
this is possible in a quick and easy manner. Press the
latches (5) on both sides and pull the mains cable
module out of the handle. Insert a new mains cable in
the handle and latch. Mains cables in various lengths
are available as special accessories.
Use the mains cable module provided only for
Kress Electro-Tools. Do not attempt to operate
other machines with the module.
