6.3.3 Setting the speed
Three rotational speeds can be set for the main saw drive by moving over the
V-ribbed belt:
• 3000 / 4000 / 5000 rpm
Changing the rotational speed
The belt tension is automatically set when the screw is turned back!
A rotational speed of only 3000 rpm is permissible with a saw blade dia-
meter of D = 550 mm (only for machines without scoring unit), for VARIO
3500 rpm.
Optimum position for changing speed/belt: Tilt saw unit to 25°!
