Instructions on operation:
Provide an uncluttered, anti-slip location with
adequate illumination.
Before tool changes, making adjustments and
eliminating malfunctions pull out the mains plug.
Never work with pieces which are too big or too
small for the machine´s capacity.
Thin, long drill bits (> 300 mm / 12 in.) at high
speed should be used only with the focussing
device.
Machine must be switched off before being con-
nected to the mains.
Before switching on, make sure that the drill bit
ist tightly secured and that the Allen key has
been removed.
Whenever possible, secure the workpiece
against slipping and tipping over (e. g. with
screw clamps).
Do not begin drilling until the drill has reached
full speed.
Examine the workpiece for foreign objects.
Never attempt to drill into nails or other metal
objects.
Keep your hands away from the underside of
the workpiece when drilling (risk of injury!).
When drilling, always lead the cable away from
the machine to the rear.
Match the feed rate to the thickness of the work-
piece when drilling. Excessive feedrates over-
load the motor, lead to poorly executed holes
and blunt the drill bit prematurely.
Do not remove the machine from the workpiece
until the drill bit is stationary.
Always keep your hands well away from the drill
bit and the drill bit mounting while the machine
is running.
The drilling machine must be operated only out-
doors or on well ventilated premises as an effec-
tive chip and dust extraction is not possible.
Instructions on service and maintenance:
Regular cleaning of the machine, especially of
the drill bit mounting, is an important safety fac-
tor. Before beginning this task, pull out the
mains plug.
Only original MAFELL spare parts and acces-
sories must be used. Otherwise the manufac-
turer does not offer any warranty and does not
accept any liability.

Setting up / Adjusting
3.1
Mains connection
The carpentry drilling machine has Class II protec-
tive insulation (double-insulated).
Before starting up, make sure that the mains voltage
matches the voltage stated on the rating plate.
3.2
Mounting and exchanging drill bits
• Lift sleeve 7 (Fig. 1) until the ring groove 8
around the arbor becomes visible. Insert the drill bit
into the arbor as far as it will go, the flat end of the
drill bit should be in line with the two small grooves 9
cut into the end of the arbor. Release the sleeve.
• When using the focussing device the star knob 15
(Fig. 2) should be loosened so that the focussing
disk 16 can be tilted. Insert the drill bit through the
hole of the correct size, return the focussing disk
to its normal position, insert the drill bit into the
arbor as described above and tighten the star
knob. Counter bore heads with
of 80 and
100 mm (3 5/32 or 3 15/16 in.) should be used
only in conjunction with the standard drill mount.
For this purpose the upper (long) springs should
be removed. Ringgroove drilling tools should be
used only in conjunction with the special drill
mount with stop plate, available as optional
accessory.
• To exchange the drill bit hold it with one hand, lift
sleeve 7 (Fig. 1) until the ring groove around the
arbor becomes visible. Remove the drill bit and
release the sleeve. Before inserting a new drill bit
make sure that the shaft of the drill bit and the
receiving, toolholding surface of the arbor are clean.

Operation
Machine must be switched off before
being connected to the mains.
Always pull out the mains plug before
changing tools.
Do not switch on the machine if the
drill bit is touching the workpiece.
