• 

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.

5.3 Sawing Capacity
