NOTE:

The  drill  speeds  specified  above  are  merely  sug

-

gested 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 im

-

mediately 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 

dropping 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 

options 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 po

-

sition 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  up

-

per 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 

suitable clamping device to secure a work piece in 

position. 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-center

-

ing 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 up

-

per 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 col

-

umn 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 injury 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
