6. Machine operation
Support long workpieces with helping
roller stands.
Work only with a sharp and flawless
sawblade.
Don't take measurements when the
machine is running
Don't chuck too short in vice.
Use the coolant facility to keep cutting
temperatures down, reduce friction
and extend the life of your sawblade.
Make sure the cutting liquid is properly
contained to the machine.
Use only water soluble cutting
emulsions and dispose of it in an
environmentally friendly manner.
Don't cut magnesium-
high danger to fire!
7. Setup and adjustments
General note:
Setup and adjustment work may
only be carried out after the
machine is protected against
accidental starting by pulling the
mains plug.
7.1 Changing blade speed
The general rule is the harder the
material being cut, the slower the
blade speed.
Low Speed (35 or 40 m/min)
for mild steel, alloy steel and bronzes.
High Speed (70 or 80 m/min)
for aluminium or other light materials.
WARNING:
Do not change the speed while
machine is running.

7.2 Changing sawblade

Disconnect the machine from the
power source.
The sawblade has to meet the
technical specification.
Check sawblade for flaws (cracks,
broken teeth, bending) before
installation. Do not use faulty
sawblades.
Always wear suitable gloves when
handling sawblades.
Raise the saw arm to the vertical
position and lock in place (close both
valves F and G).
Remove the wheel cover.
Move the blade guide assembly (N,
Fig 2) away from the wheel.
Remove the brush assembly.
Release the blade tension and remove
the blade.
Place new blade and make sure the
teeth are pointing the cutting direction
(Fig 5).

Disconnect the machine from the
power source.
Loosen bolts and adjust assembly (B)
so that back roller bearing is
approximately 0,1mm from the back
of the blade. Tighten bolt.
