6. Operation
6.1 General information (Fig. 16)
Before you switch on the machine, open the cover
(32) over the On/Off switch.
To switch on, press the green On switch "I" (18);
the machine will then start up. To switch off , press
the red "O" button (19); the machine will then shut
down.
Take care not to overload the machine. If the
sound of the motor drops in pitch during operati-
on, it is being overloaded.
Do not overload the machine to the point where
the motor comes to a standstill. Always stand in
front of the machine during operation.
6.2 Inserting a tool in the drill chuck (Fig. 1)
Make sure that the power plug is removed from
the socket-outlet before changing tools. Only
cylindrical tools with the stipulated maximum
shaft diameter are allowed to be clamped in the
drill chuck (10). Use only tools that are sharp and
free of defects. Do not use tools whose shaft is
damaged or which are deformed or fl awed in any
other way. Use only accessories and attachments
that are listed in the operating instructions or have
been approved by the manufacturer. If the pillar
drill becomes jammed, switch off the machine
and return the drill to its starting position.
6.3 How to use the scroll chuck (Fig. 17)
The pillar drill is equipped with a scroll chuck. To
insert a drill bit you must fi rst swing the chip guard
(13) to the side. Then insert the bit and tighten
the chuck (10) with the supplied chuck key (27).
Hazard! Do not leave the chuck key inserted. An
inserted chuck key would be catapulted into the
surroundings, with a high risk of injury.
6.4 Using tools with tapered shanks (Fig. 18)
The pillar drill comes with a spindle taper. To use
tools with tapered shanks (MK2), proceed as
follows:
•
Move the drill chuck to the lower position.
•
Use the scale ring (25) to lock the spindle in
the lowered position so that the opening for
moving out the drill chuck remains unobstruc-
ted (Fig. 18).
•
Eject the tapered shank using the supplied
drill drift (35), taking care as you do so to en-
sure that the tool does not land on the floor.
•
Jerk a new tool with tapered shank into the
spindle taper and check that the tool is firmly
seated.

6.5 Speed settings (Fig. 16/19-21)
First switch off the machine, then pull out the
power plug.
The various spindle speeds can be set by chan-
ging the position of the V-belt.
Proceed as follows:
•
First move the fastening rail for the chip guard
(23) into the lowest position so that the V-belt
cover can be fully opened. To do so, undo the
securing screw of the chip guard (22) to ena-
ble the fastening rail for the chip guard to be
pushed downwards (Fig. 16).
•
Slacken the locking screw (15) so that you
can open the V-belt cover (7) and then sla-
cken the tightening screw (16) on the machi-
ne head (6) (Fig. 19).
•
Turn the clamping lever (17) clockwise to re-
move tension from the V-belt (26) (Fig. 20a).
•
Change the position of the V-belt to suit the
required speed.
•
Please refer to the table (Fig. 21) for the cor-
responding speeds.
•
Re-tension the V-belt by turning the clamping
lever counter-clockwise (Fig.20b).
Note: The tension is properly set when you
can depress the V-belt in the middle by ap-
prox. 1 cm.
•
Then re-tighten the tightening screw on the
machine head.
•
Re-close the V-belt cover and tighten with the
locking screw.
Note: The V-belt cover must always be shut tight
because the machine is equipped with a safety
switch that allows the machine to be switched on
only when the V-belt cover is closed.
Hazard! Never let the pillar drill run when the V-
belt cover is open. Always pull out the power plug
before opening the cover. Never touch the V-belt
when it is rotating.
6.6 Drill depth stop (Fig. 22)
The drilling spindle has a swiveling scale ring for
setting the drilling depth. Adjust the settings only
when the machine is at a standstill.
•
Press the drilling spindle (11) downwards until
the tip of the drill bit touches the workpiece.
•
Slacken the clamping screw (14) and turn the
scale ring (25) forwards until it stops.
•
Turn the scale ring back to the required dril-
ling depth and lock this setting with the clam-
ping screw.
