chip guard (13) to the machine. Finally swing up the
chip guard, push the scroll chuck (10) with a jerk onto
the taper and check that the tool is securely seated.
The height of the cover (23) is infinitely adjustable
and can be locked using both thumb screws (22).
The chip guard (13) can be flipped upwards to
change drill bits, however ensure that the chip guard
(13) is back in its initial position before restarting the
equipment.
6.4. Prior to using the machine for the first time
Ensure that the voltage of the mains supply complies
with the specifications on the rating plate. Connect
the equipment only to a socket with the properly
installed earthing contact. The drill is equipped with a
no-volt trip that is designed to protect the operator
from an undesired restart following a drop in voltage.
Should this happen, the equipment must be
physically restarted.
7. Operation
7.1. General (Fig. 2)
To switch on the equipment, push in the green On
button “I” (18); the drill starts up. To switch off, press
the red Off button “O” (19); the drill shuts down.
Ensure that you do not overload the equipment.
If the sound of the motor drops in pitch during
operation, it is being overloaded.
Do not overload the equipment to the point where the
motor comes to a standstill.
7.2. Fitting tools to 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 may
be clamped in the drill 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. Using the quick-change drill chuck
Your drill is equipped with a gear-toothed drill 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 tool is
firmly seated.
Danger!
Do not leave the chuck key in the clamp
hole. Doing so will cause the chuck key to be
catapulted out, which could cause injury.
7.4. Setting the speed (Fig. 1/8/9)
First switch the equipment off, then pull the power
plug.
The various spindle speeds can be set by moving the
V-belt.
Proceed as follows:
n
Remove the screw (16) in order to open the V-belt
cover (7).
n
Slacken the tightening screw (15) and push the
motor (8) in the direction of the machine head.
n
Move the V-belt to the desired position.
n
Refer to table (Fig. 8) for the recommended
speeds.
n
Tighten the V-belt by pushing the motor (8) away
from the drill 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.
n
Close the V-belt cover and screw down using the
screw (16). The V-belt cover (7) must always be
locked tight, as the equipment is equipped with a
safety switch that only allows the equipment to be
turned when the V-belt cover (7) is closed.
Danger!
Never let the pillar drill run when the V-belt
cover is open. Always pull power plug before opening
the cover. Never touch the V-belt when it is rotating.
7.4.1 Drill depth stop (Fig. 10)
The drilling spindle has a swivelling scale ring (25) for
setting the drill depth. Only adjust the setting when
the equipment is at a standstill.
n
Press the drilling spindle (11) downwards until the
tip of the drill bit touches the workpiece.
n
Slacken the clamping screw (17) and turn the
scale ring (25) forwards until it stops.
n
Turn the scale ring (25) back to the desired drill
depth, then lock this setting into place using the
clamping screw (17).
When setting the drill depth of a cylindrical hole you
must add the length of the drill tip.
7.5. Setting the angle of the drill table (Fig. 7)
n
Slacken the carriage bolt (26) under the drill table
(4).
n
Set the drill table (4) to the desired angle.
n
Tighten down the carriage bolt (26) in order to
lock the drill table (4) into this position.
7.6. Setting the height of the drill table (Fig. 1)
n
Slacken the tightening screw (5).
n
Set the drill table (4) to the desired height by
pressing down or lifting up and simultaneously
(gently) pushing to the left or right.
n
Screw the tightening screw (5) back down again.
