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.
25 m/min
for tool steel, alloy steel and bearing
bronzes.
40 m/min
for mild steel, hard brass or bronze.
50 m/min
for soft brass
70 m/min
for aluminium or other light materials.
Disconnect the machine from the
power source.
Place saw arm in the horizontal
position.
Open pulley cover and place the belt
on the desired pulley combination.
Tension the belt (don’t over tighten the
belt).
Close the pulley cover and connect to
power source.
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).
Open the wheel covers.
Move the blade guide assemblies (B,
Fig 5) away from the wheel.
Fig 5
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 6).
Fig 6
Turn the blade tension knob until the
proper blade tension is achieved at
green block of tension scale .
Place a few drops of lightweight oil on
the blade.
Install the red blade guard, the brush
assembly and close the wheel cover.
Connect to the power source.
7.3 Blade guides adjustment
Disconnect the machine from the
power source.
Slide blade guide assemblies as close
as possible to the material being cut.
7.4 Guide bearing adjustment
Disconnect the machine from the
power source.
Loosen bolts (A, Fig 7) and adjust
assembly (B) so that back roller
bearing is approximately 0,1mm from
the back of the blade. Tighten bolt.
Fig 7
Fig 8
Loosen blade guides (A, Fig 8) by
loosening screws (B). Slide blade
guides away from the blade.
Loosen locking nuts with a hex
wrench.
Turn eccentric shaft (C) to adjust
bearing to a clearance of 0,05mm.
Tighten nut to lock.
Slide blade guides (A) back into
contact with the blade and tighten
screws (B).
