6. Carefully turn the spring cap (2) counterclockwise

with the screwdriver until you can press the nut (1)

into the hub (6).

7. Lower the spindle to the lowest position and hold

the spring cap (2) in position. When the spindle

moves up and down as you wish, tighten the inner

nut (4) again.

8. If it’s too loose, repeat steps 3-5. If it’s too tight,

reverse the step 6.

9. Secure the outer nut (3) against the inner nut (4)

with an open-ended wrench.

10. NOTE: Do not overtighten and do not restrict the

movement of the spindle!

The axial operation of the spindle (Fig. 18)

When the spindle is in the lower position, turn it by

hand. If you nd that the operation is too big, proceed

as follows:

1. Loosen the lock nut (21).

2. Turn the screw clockwise (22), to balance the op-

eration, without interfering with the up and down

movement of the spindle (a little operation is nor-

mal).

3. Tighten the lock nut (21) again.

Clamping the workpiece

As a general rule, use a machine vice or another suit-

able clamping device to secure a workpiece in po-

sition. Never hold the workpiece in place with your

hand! When drilling, the workpiece should be able to

travel on the drill table (4) for self-centering purposes.

Ensure that the workpiece cannot rotate. This is best

achieved by placing the workpiece /machine vice on

a sturdy block.

Attention! 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 workpiece.

There must be enough distance between the upper

edge of the workpiece and the tip of the drill bit.

Working speeds

Ensure that you drill at the proper speed. Drill speed

is dependent on the diameter of the drill bit and the

material in question.

The table below acts as a guide for selecting the

proper speed for various materials.

The drill speeds specied are merely suggested

values.

Setting the speed (Fig. 1)

The operating speed of the machine is innitely ad-

justable.

Attention!

• Speed adjustments are allowed only when the mo-

tor is running.

• Slowly and steadily move the speed control lever

(6) while the machine is in idle mode.

• Ensure that the machine can run without interrup-

tion (i.e. remove workpieces, drill bits, etc.).

Use the speed control lever (6) to innitely adjust the

speed. The set speed is shown on the digital display

(8) in revolutions per minute.

Attention! 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.

Drill depth stop (g. 15a)

The drilling spindle has a swivelling scale ring (19) for

setting the drill depth. Only adjust the setting when

the equipment is at a standstill.

• Press the drilling spindle downwards until the tip of

the drill bit touches the workpiece.

• Slacken the clamping screw (18) and turn the scale

ring (19) forwards until it stops.

• Turn the scale ring (19) back to the desired drill

depth, then lock this setting into place using the

clamping screw (18).

Attention! When setting the drill depth of a cylindri-

cal hole you must add the length of the drill tip.

Setting the angle of the drill table (g. 1/15)

• Slacken the carriage bolt (20) under the drill table

(4).

• Set the drill table (4) to the desired angle.

• Tighten down the carriage bolt (20) in order to lock

the drill table (4) into this position.

Setting the height of the drill table (g. 16)

• Slacken the tightening screw (3).

• Set the drill table to the desired position with the

help of the hand crank (16).

• Screw the tightening screw (3) back down again.

Adjusting the spindle return spring (g. 17)

It may be necessary to adjust the spindle return

spring because its tension has changed and the spin-

dle moves back too quickly or too slowly.

1. Lower the table for more work space.

2. Work on the left side of the drill.

3. Insert a screwdriver into the lower front groove (1)

and hold it.

4. Remove the outer nut (3) with an open-ended

wrench (SW14)

5. With the screwdriver still in the nut, loosen the in-

ner nut (4) until the notch detaches from the hub

(6). ATTENTION Spring is under tension!
