FEED SPEED
Feed speed is how quickly you push the saw blades
through the material being cut. The correct feed speed
is totally determined by the hardness and the thickness
of the material being cut.
The correct feed speed to be used depends on the
hardness and the thickness of the material to be sawn.
Only feed the blades down approximately 3/8". Then
start cutting.
1. If the feed speed is too slow
• The blades will only press down on the material
rather than cutting it.
• The blade edges glides and wears down the material.
• This will cause a poor cut and will cause excessive
wear on the blades.
2. If the feed speed is too fast
• There is a definite risk that the cut might split. The
splinter will get bigger and bigger and eventually
break risking serious personal injury..

Correct care makes good economic sense !
CLEANING AND STORAGE
Resin and other materials that easily become attached to
the sides of the blade often cause the blade to overheat.
This means that it can buckle or even split. You must
therefore always keep the blade clean. Wash it with a
solvent. Never try to scrape the blade clean with a hard
object.
When the blade is not in use, it should be stored in its
original sheath, well cleaned and coated with an antirust
agent.
RE-GRINDING AND RENOVATION
It is not economical to use a blunt blade. If you do, the
teeth can be damaged and it is then necessary to grind
away an excessive amount of hard metal when
sharpening it, which reduces the blade’s life span and the
risk of personal injury.
SELECTING THE CORRECT FEED IS
IMPORTANT
If the feed speed is too low, the blades will only press
down the material rather than cutting it. The edge glides
or wears down the material. The result is a poor cut and
rapid wear of the blades.
If the feed speed is too high there is a risk that the cut
might split and the splinter opening’s volume will not be
sufficient to divert all the shaving. The result is a poor cut
with significant discharge on the lower side of the
material.
Feeding must be parallel to the blade. Feeding at an angle
can burn the blade and damage the teeth.
6. INSTRUCTIONS FOR CUTTING
VARIOUS CROSS SECTIONAL
MATERIALS
As everyone knows, the life span of the blade and the
quality of the cutting edge is dependent on vibrations
being kept to a minimum. For this reason the material
must always be clamped in place before work proceeds.
Flat bar iron
Fig.8
The blade is fed at an angle of 90° to the work surface.
Corner piece
Fig.9
The blade is fed diagonallythrough the work surface.
Rectangular pipe
Fig.10
The blade is fed from corner to corner.
U-section
Fig.11
The blade is fed from cornerto corner.
Aluminium/copper
Fig.12
The machine must always be equipped with the
lubricating device, to be used when cutting all kinds of
aluminium and copper.
Shaped plate
Fig.13
The plate must always rest on three mounts, with one on
either side of the cut.
Pipes
Fig.14
The blade is fed through the object until it reaches the
lower edge, angled as it goes so that the blade hits the
material at an angle of 90°.
Spiral tube and longitudinal cutting
Fig.15
Feed the blade through the material, so that the blade
only protrudes through approx. 10 mm, do not drive it
as far as the bladeís entire cutting edge. Then start to
feed the blade forwards or backwards.
Thin plate
Fig.16
Only feed the blade down approx. 10 mm. Then start
cutting.
The Blade Cover Guard is fixed to protect the operator
from chips.When the blades rotates, the chip flow
comes out in both directions, which must be observed.
7. REMOVAL OF USED
TWINCUTTER SAW BLADES
1. Unplug the saw and allow blades to cool.
2. Rotate the blades until holes in both the blades are
