2. Loosen the drive belt on the right side of the machine
head by unfastening the locking nuts (12) on both sides.
Pull the right side of the motor in the direction of the spin-
dle to loosen the v-belt. Tighten the counternuts again
(12).
3. Attach the v-belt to the corresponding belt pulleys. The
belt must always run straight.
4. Loosen the counternuts (12) and press the right side of
the engine back, in order to tension the V-belt again.
5. Tighten the counternuts again (12). Belt should deflect
approximately 13 mm –1/2“ -by thumb pressure at mid-
point of belt between pulleys.
6. Close the belt guard (11).
7. If belt slips while drilling readjust belt tension.
Tip: Safety switch
If you wish to set the speed, you must open the belt guard (11).
The device switches off immediately to avoid the risk of injuries.
Removing the chuck
Open jaws of chuck as wide as they go by turning chuck sleeve
anticlockwise.
Carefully tap chuck with mallet in one hand while holding
chuck in other hand to prevent dropping it when released from
spindle nose.
Fitting tools to the drill chuck
Make sure that the power plug is removed from the socket-
outlet before changing tools.
Only cylindrical tools with the stipulated maximum shaft diam-
eter may be clamped in the drill chuck (5). 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 manufac-
turer.
Using the drill chuck
Your drill is equipped with a gear-toothed drill chuck (5). In
order to insert a drill bit, first fold the chuck guard (7) up, then
insert the drill bit and tighten the chuck (5) with the chuck key
(D) supplied.
Pull out the chuck key (D).
Ensure that the clamped tool is firmly seated.
Important! 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.
Depth scale method, Fig. 6
Note:
for this method, with the spindle in its upper position
the tip of the drill bit must be just slightly above the top of the
workpiece.
1. Switch off the machine, lower the drill so far until the in-
dicator points at the desired drilling depth of the depth
scale.
2. Turn the lower nut (J2) to the hole (I) stop.
3. Lock the top nut (J1) against the bottom nut (J2).
4. The chuck and the drill bit will now be stopped after trave-
ling downward the distance selected on the depth scale.
Clamping the workpiece (Fig.13+14)
As a general rule, use a machine vice or another suitable
clamping device to lock a workpiece into position.
Never hold the workpiece in place with your hand!
When drilling, the workpiece should be able to travel on the
drill table (3) 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.
Important!
Sheetmetal parts must be clamped in to prevent them from be-
ing 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 tip of the drill bit.
Positioning table and workpiece, Fig. 14
Always place a piece of back up material (‘wood, plywood...)
on the table undemeath the workpiece. This wiII prevent spliter-
ing or making a heavy burr on the underside of the workpieces
as the drill bit breaks through. To keep the back up material
from spinning out of control it must contact the left side of the
column as illustrated.
Warning:
To prevent the work piece or the backup material from being
torn from your hand while drilling, position them to the left side
of the column. If the work piece or the backup material are
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.
The vice must be clamp or bolt to the table to avoid injury from
spinning work and vise or tool breakage.
Mounting the machine vice on the drilling table
Fasten the machine vice using the screws, washers and nuts
provided, as shown in Fig. 13.
Using the laser (Fig.15+16)
Replacing the battery:
Switch off the laser. Remove the battery compartment cover
(13.2). Remove the batteries and replace with new batteries.
To switch on:
Move the ON/OFF switch (13.1) to the “I” position to switch
on the laser.
Two laser lines are projected on the workpiece and intersect at
the center of the drill tip contact point.
To switch off:
Move the ON/OFF switch (13.1) to the “0” position.
Working speeds
Ensure that you drill at the proper speed. Drill speed is depend-
ent 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.
