The table below acts as a guide for selecting the
proper speed for various materials:

4 1.900 1.200
5 1.530 955

20 380 240
22 350 220
25 305 190
NOTE:
The drill speeds specified above are merely suggest-
ed values.
4. Loosen the wing screws and push the right side of
the motor backwards to clamp the v-belt again.
5. Tighten belt tension lock knob. Belt should have
approximately 13mm of play with thumb pressure
at mid-point of belt pulleys.
NOTE:
Safety switch: If you want to adjust speed you have to
open the pulley cover. The device switches off immedi-
ately to avoid the risk of injuries.
Removing the chuck:
Open jaws of chuck as wide as they go by turning
chuck sleeve anticlockwise (when viewed from
above). Carefully tap chuck with mallet in one hand
while holding chuck in other hand to prevent drop-
ping it when released from spindle nose.
Adjusting depth stop:
The depth stop enables the drilling of holes in the
work piece until a defined depth. You have two op-
tions for that.
a. Drilling to a specific depth (Fig. 14):
1. Mark the drilling depth (H) on one side of
the work piece.
2. Bring the drill bit down until the tip of the
mark.
3. Hold the feed handle at this position.
4. Spin the lower nut (B2) down to contact the
depth stop (13) on the head.
5. Spin the upper nut (B1) down and tighten
against the lower nut.
6. Τhe chuck and the drill bit are now going to
be stopped after traveling downward the

distance selected on the depth scale.
b. Depth scale method (Fig. 6):
NOTE:
For this method, with the spindle in its upper posi-
tion the tip of the drill bit must be just slightly above
the top of the work piece.
1. Lower the drill so far until the indicator (g)
points at the desired drilling depth of the
depth scale (e).
2. Turn the lower nut (B1/2) downwards until it
reaches the lower stop (13).
3. Lock the lower nut (B1/2) against the upper
nut.
4. The chuck and the drill bit will now be
stopped after traveling downward the dis-
tance selected on the depth scale.
Positioning the work piece (Fig. 15):
As a general rule, use a machine vice or another suit-
able clamping device to secure a work piece in po-
sition. Never hold the work piece in place with your
hand. When drilling, the work piece should be able to
travel on the drill table for self-centering purposes.
Ensure that the work piece cannot rotate. This is best
achieved by placing the work piece /machine vice on
a sturdy block.
NOTE:
Sheet metal parts must be clamped in to prevent
them from being torn up. Properly set the height
and angle of the drill table for each work piece. There
must be enough distance between the upper edge
of the work piece and the tip of the drill bit.
NOTE:
Place a piece of backup material (e.g. wood) on the
table underneath the work piece. This will prevent
splitting or making a heavy burr on the underside of
the work pieces as the drill bit breaks through.
WARNING:
To keep the backup material from spinning out of
control it must contact the left side of the column as
illustrated. If the work piece or the backup material
is not long enough to reach the column, clamp them
to the table. Failure to do this could result in personal
injury.
NOTE:
For small pieces that cannot be clamped to the table,
use a drill press vise (optional accessory). The vice
must be clamped or bolted to the table to avoid in-
jury from spinning or breakage.
Drilling a hole:
Make a dent in the work piece where you want the
hole, using a center punch or a sharp nail. Before
turning the switch on, bring the drill down to the
work piece lining it up with the hole location. Turn
the switch on and pull down on the feed handles
with just enough effort to allow the drill to cut.
Feeding slowly might cause the drill bit to burn.
Feeding quickly might stop the motor, cause the belt
or drill to slip, tear the work piece loose, or break the
drill bit.
NOTE:
When drilling metal, it may be necessary to lubricate
the tip of the drill with motor oil to prevent burning the
drill bit.
