Hieruit volgt dat naslijpen alleen op speciale daarvoor geschikte machines moet gebeuren. Als de zaag haar snijkracht
heeft verloren, moet u niet proberen om door overmatige druk op de trekstang te blijven zagen. Het gevolg kan zijn
dat er tanden uit de zaag breken en dat de kosten voor het naslijpen verdubbelen.

Voor de maximale capaciteit in mm zie onderstaande tabel voor de profielvorm/doorsnede in relatie tot de
verstekhoek. Met 90º bedoelen we recht doorzagen.

onteren en wIsselen van het zaagblad
• Zet de hoofschakelaar in de stand Off.
• Zet de zaagkop in de bovenste stand.
• Schuif de schaaldelen (A, afb 4) open.
• Draai de inbusbout M8 van de zaagas (B, afb.4) los en verwijder de zaagflens.
• Verwijder het zaagblad.
• Maak zaagas en zaagflens goed schoon.
• Montage gebeurt in omgekeerde volgorde en let op de draairichting van het
zaagblad.
Controleer de instelling van de zaagdiepte (let op de instructie op de zaagflens,
zie afbeelding 4. Vergeet niet de beschermkap weer te sluiten door de curveplaat
op zijn plaats te brengen. Let erop dat het zaagblad goed vlak tegen de flens van
de zaagas aanligt.

aagvoedIng
Handvoeding
De zaag wordt door middel van de trekstang op het materiaal gebracht. Druk het
zaagblad stevig op het materiaal zonder overmatige kracht te gebruiken. Een te
hoge zaagdruk kan zaagbreuk tot gevolg hebben, een te lage zaagdruk maakt de
zaag snel bot.

aagsnelheId
De zaagsnelheid wordt ingesteld met de keuze schakelaar (A, afb. 5)
De volgende snijsnelheden zijn mogelijk:
HU 250/LT > Snijsnelheid in stand 1: 20 omw/min in stand 2: 40 omw/min
HU 250/HT > Snijsnelheid in stand 1: 40 omw/min in stand 2: 80 omw/min
Elk materiaal heeft zijn eigen snijsnelheid. Onderstaand richtlijnen voor enkele materialen:
20 omw/min > voor gelegeerd staal, bijvoorbeeld RVS
40 omw/min > voor normaal staal
80 omw/min > voor non-ferrow metalen

cavity are of the utmost importance. The tooth cavity must be large enough for the
removed chips to be bend as long as the tooth is cutting. When the cutting tooth
leaves the saw cut, the chip drops out of the tooth cavity.
The alternate saw (alternately bevelled edge) is often used for small pitches,
especially up to 4 mm.
The precutting and finishing teeth are used for larger, solid material, usually from
pitch 4 mm onwards. These teeth ensure that the chips are not all of the same length.
If a chip were to be cut out the normal way, it would get hot, expand and become
wider than the width of the cut. This would caus e it to get stuck, as a result of which
the chip could not be removed from the cut. The finishing tooth must be positioned
0.2 to 0.4 mm higher than the precutting tooth. The larger the pitch, the higher the
precutting tooth must be placed as compared to t he finishing tooth.
Consequently, only special machines are suitable for regrinding these teeth. When
the blade has lost its cutting power, do not strain it. As a result the teeth may break
off, which doubles the regrinding costs.
5.3 Sawing Capacity
For the maximum capacity in mm see the schedule for the profile figure/cross -cut in
relationship with the mitre angle. Write 90º we mean straight sawing.

5.4 Installing and replacing the saw blade
• Set the main switch in the off position.
• Put the saw head in the upper position.
• Open the guards (fig. 5.03A).
• Release the socket head screw M8 of the saw spindle
(fig. 5.03B) and remove the saw flange.
• Remove the saw blade.
• Carefully clean the saw spindle and the saw flange.
• Installing is done in reverse order. Pay attention to the
direction of rotation of the sawblade. Make sure the saw blade is
placed flush against the flange of the saw spindle. Check the
setting of the sawing depth (see chapter 4.2). Do not forget to close the safety guard.

5.5 Saw feed
Manual saw feed The saw feed is determined by
hand. The saw is lowered onto the material by means
of the handle. Press the saw b lade firmly onto the
material, without using unnecessary force. When the
saw pressure is too high this can cause the saw to
break; when the saw pressure is too low, te saw will
rapidly go blunt.
5.6 Sawing speed
The following cutting speeds are po ssible:
HU 250 CS > speed in position 1: 40 m/min.
in position 2: 80m/min
Every material has it’s own cutting speed. Below advice for some materials:
20 m/min > For steel alloy e.g. stainless steel
40 m/min > For normal steel
80 m/min > For non-ferrous materials
5.7 Clamping the material
It is of the utmost importance that the material is safely clamped in the double material
vice, so that it cannot tilt over or even move during sawing. In ord er to work efficiently,
the material must always be clamped in such a way that the contact surface of the saw
and the material is as small as possible. For instance, saw flat material on its thinnest
side; this will considerable shorten sawing times. When very short pieces have to be
sawn, and consequently only half of the material vice
will be used, in order to prevent it from pulling out of
alingment, a piece of material of equal thickness must
be clamped in the other half of the vice. In this way the
material is clamped tightly and evenly. Application of
special vice jaws is recommendable for
repetitive work
The sawing depth can be limited by means of an
adjustable ring, see chapter 4.2
Mitre-sawing
Pull the clamping rod (fig. 5.06B) to the right and turn the sawing unit in the required mitre
position. The position can be read out on the scale division (fig 5.06A). Then fasten the
clamping rod again. Do not use unnecessary force, a slight pull will su ffice. Before clamping
the material, check whether the saw is running completely clear between the jaws of the
material vice. Place the steel vice jaws as closely as possible to the saw.
