The inside of the drill spindle must be degreased completely. For this purpose use
environmentally friendly solvents. Proceed in the same way with the drill head pin. A correct
transmission can only be achieved in this way.
4. OPERATION, HINTS AND TIPS
Depth stop
The drill spindle is provided with a depth stop. It can be adjusted using the nut. The drill depth
can be read on the scale division.
Clamping the drill
Fig.F
In the drill head of the bench drill, drills and other tools with a cylindrical shank can be clamped.
The moment of rotation is transferred to the drill by means of the tension of the three clamping
jaws. To prevent the drill from sliding away, it must be clamped using the toothed ring wrench.
If the drill slides away in the drill holder, a slight burr occurs on the drill shank, which makes
centric clamping impossible. A burr which occurs in this way must in any case be removed by
grinding
Clamping the workpiece
Fig.G
The drill bench and the footplate of the bench drill are provided with grooves for fastening
clamping tools. Always clamp the workpiece in the machine clamp or other clamping tools. In
this way you will prevent accidents and even increase the drilling accuracy because the
workpiece is in a fixed position.
Adjusting the bench
Fig. H
The drill bench is fastened to the drill column and can be adjusted in height after loosening the
fastening handle. Adjust the bench in such a way that there is still enough space between the
top of the workpiece and the point of the drill. You can also swivel the bench sideways, if you
wish to clamp a workpiece directly onto the footplate.
Fig.I
For slanted drilling and with a slanted supporting surface of the workpiece the bench can be
swivelled. For this purpose loosen the hexagonal screw (20) on the hinge point (21) of the
bench and remove the centring. Swivel the bench (19) to the desired position. Then screw
down the hexagonal screw (20) properly using a wrench.
Number of revolutions, speed of rotation, supply
The supply - the feed motion of the drill - takes place by hand on the 3-armed drill lever. The
speed of rotation is determined by the number of revolutions of the drill spindle and by the
diameter of the drill. The correct choice of supply and the number of revolutions of the drill
spindle are the deciding factors for the lifespan of the drill. The following applies as a basic
rule: with a larger diameter of the drill the number of revolutions must be adjusted lower; the
greater the firmness of the workpiece, the greater the cutting pressure must also be.

•
Borepatronens tandkrans må kun fastspændes med den nøgle, der er bestemt til dette
formål.
•
Lad aldrig nøglen til borepatronen sidde i borepatronen! Kontrollér, at nøglen faktisk er
fjernet, inden maskinen tændes.
•
Brug ikke bor, hvis hals er beskadiget.
•
Boremaskinen er ikke egnet til fræsning!
•
Når netledningen er beskadiget, må den kun udskiftes med en tilsvarende netledning.
Maskinen skal øjeblikkeligt slukkes i til fælde af:
•
Defekt netstik, netledning eller beskadigelse af ledning;
•
Defekt kontakt;
•
Gnistdannelse i kullene eller ringild i kollektoren;
•
Røg eller lugt fra sveden isolering.
Elektrisk sikkerhet
Kontroller alltid om nettspenningen er i overensstemmelse med verdien på typeskiltet.
Maskinen er udstyret med en nulspændingsomskifter. Når spændingen bortfalder
ved strømsvigt, tilkobles maskinen af sikkerhedsgrunde ikke længere automatisk.
Maskinen skal derfor tændes på ny.
Ved udskiftning af ledninger og stik
Kasser gamle ledninger og stik, så snart de er skiftet ud med nye. Det er farligt at sœtte et stik
fra en løs ledning i en stikkontakt.
Ved brug af forlœngerledninger
Brug udelukkende godkendte forlœn gerledninger, der er beregnede til maskinens effekt.
Lederne skal have et gennemsnit på mindst 1,5 mm
tromle, rulles ledningen helt af.
3. MONTAGE
Fig. B
•
Bundpladen (13) opstilles på den rigtige plads.
•
Søjlen (11) fastgøres på bundpladen med de bolte (12), der fulgte med maskinen.
•
Holderen for bordet (10) med bordet skydes over søjlen. Bordet fastgøres med
låsestangen (6) i den ønskede position.
•
Nu monteres maskinhuset (7) og sikres ved hjælp af sikringstifterne (8).
•
Borespindlen er smurt fra fabrikken. Derfor anbefales at lade maskine løbe i laveste gear i
ca. 15 minutter.
Før borehovedet med stiften (9) stikkes ind i borespindlen, skal borespindlens
indre være helt fri for fedt!
Opstilling af bænkboremaskinen
Inden boremaskinen anvendes, skal den monteres på et fast underlag.
