•
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.

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 blade 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.

speed
The following cutting speeds are possible:
•
speed in position 1: 40 m/min.
•
in pos ition 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

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

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.

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.
