Gear should be shifted only when the
motor has been switched off and the
machine is running out or has stopped
(see Fig. 4)! When the machine has
been switched on the direction of rota-
tion of the drill bit should be checked. If
necessary, the direction of rotation can
be changed by means of the reversing
switch 6 (Fig. 2). Before actuating the
reversing switch the motor should be
switched off (the reversing switch is
mechanically blocked).

Operating instructions
Bolt 10 (Fig. 2) should be pushed down as far as
possible and fastened with clamping screw 12.
Place the machine so that the guide pilot pin of the
cutting tool is inserted into the hole in the timber.
Turn the machine until the bolt touches the timber so
that it can act as a stop for torsional force. When the
machine has been switched on it should be pushed
down. It is possible to set the cutting depth by
means of the depth stop ring 11.

Service and maintenance
Pull out the mains plug before start-
ing on any maintenance work!
MAFELL machines are designed to be
low in maintenance. The ball bearings
used are greased for life. After a pro-
longed period of operation, users are
recommended to have the machine
checked by an authorized MAFELL cus-
tomer service shop.
5.1
Machine
The machine must be cleaned of dust deposits at
regular intervals. When doing so, clean the air vents
on the motor using a vacuum cleaner.
5.2
Tools
The drill bits used on the machine must be freed
from resin regularly, as clean tools improve the drill-
ing quality.
5.3
Storage
If the machine is out of service for a lengthy period of
time, it should be thoroughly cleaned (see
chapter 5.1). Spray bright metal panels with a rust-
proofing agent.
Store the machine only in dry rooms, where it is pro-
tected against weathering.
