7.2. Inserting the tool (Fig. 1/2)
Make sure that the power plug is removed from the
socket-outlet before changing tools. Only cylindrical
tools with the stipulated maximum shaft diameter
may be clamped in the scroll chuck (10). Only use a
tool that is sharp and free of defects. Do not use
tools whose shaft is damaged or which are deformed
or flawed in any other way. Use only accessories and
attachments that are specified in the operating
instructions or have been approved by the
manufacturer.
7.3. Handling the drill chuck (Fig. 1/2)
Your table drill is equipped with a scroll chuck (10).
In order to insert a drill bit, flip up the chip guard (13),
insert the drill bit, then tighten down the drill chuck
using the supplied chuck key.
Pull out the chuck key. Ensure that the clamped in
tool is firmly seated.
Caution! Do not leave the chuck key in the clamp
hole.
Doing so will cause it to shoot out, which could cause
injury.
7.4. Setting the speed (Fig. 1/2/7/8/10/11)
First switch the machine off, then pull out the mains
plug.
The various spindle speeds can be set by moving the
V-belt.
Proceed as follows:
쎲
Remove the screw (16) in order to open the V-
belt cover (7).
쎲
Slacken the tightening screw (15) and push the
motor (8) in the direction of the machine head.
쎲
Move the V-belt to the desired position.
쎲
Refer to the table for the recommended speeds
for different drill bit materials (Fig. 7/10).
쎲
Tighten the V-belt by pushing the motor (8) back
from the machine head (6). Screw the tightening
screw (16) back down again. The tension is
properly set when the V-belt flexes in the middle
by approx. 1 cm when pressed.
쎲
Close the V-belt cover and screw down using the
screw (16).
The V-belt cover (7) must always be locked tight,
as the machine is equipped with a safety switch
that only allows the machine to be turned on
when the V-belt cover (7) is closed.
Caution!
Never let the pillar drill run when the V-belt
cover is open. Always pull the mains plug before
opening the cover. Never touch the V-belt when it is
rotating.
7.5.1 Drill depth stop NBD 401 (Fig. 9)
The drill depth can be set exactly by means of the
depth stop (14) and a scale (a) on the front side of
the machine head. The machine must be switched
off in order to set the depth stop.
쎲
Insert the required bit (7.2) and turn the setting
screws up.
쎲
Using the handle, move the bit so that its tip just
touches the surface of the workpiece and read
the value indicated on the scale.
쎲
Remove the workpiece.
쎲
Add the required drill depth to the value you read
off the scale and use the handle to lower the bit
until the value you calculated is indicated on the
scale.
쎲
Turn down the lower setting screw as far as it will
go.
쎲
Secure the setting by turning the upper setting
screw against the lower setting screw.
Important!
When setting the drill depth of a
cylindrical hole you must add the length of the drill tip
7.5.2 Drill depth stop point NBD 501 (Fig. 12)
The drilling spindle has a swiveling scale ring for
setting the drill depth. Only adjust the setting when
the machine is at a standstill.
-Lower the drilling spindle (11) until the tip of the drill
bit touches the workpiece.
-Slacken the clamping screw (17) and turn the scale
ring (25) forwards until it stops.
-Turn the scale ring (25) back to the desired drill
depth, then lock this setting into place using the
clamping screw (17).
7.6. Setting the angle of the drill table (Fig. 6)
쎲
Slacken the carriage bolt (26) under the drill
table (4).
쎲
Set the drill table (4) to the desired angle (which
can be read off the scale on the top side of the
drill table).
쎲
Tighten down the carriage bolt (26) in order to
lock the drill table (4) into this position.
7.7. Setting the height of the drill table (Fig. 1/2)
쎲
Slacken the tightening screw (5).
쎲
Set the drill table (4) to the desired height by
pressing down or lifting up and simultaneously
(gently) pushing to the left or right.
쎲
Screw the tightening screw (5) back down again.
7.8. Locking the workpiece into position (Fig. 1)
As a general rule, use a machine vice (14) or another
suitable clamping device to lock a workpiece into
position.
