• Move the guide pins (29) towards the blade so that there is a gap of approx. 0.5 mm between
the guide pins (29) and the blade (26). The blade must not jam.
• Re-tighten the Allen screws (38).
• Turn the lower blade pulley (7) several times in a clockwise direction.
• Check the setting of the guide pins (29) again and re-adjust if necessary.
Caution!
When the adjustments have been finished, the blade guard (34) must be closed again.
Attention!
7.5. Adjusting the upper blade guide (11) (Figure 11)
• Undo the fixing handle (20).
• Turn the setting wheel (19) to lower the blade guide (11) as close as possible to the workpiece
to be cut. The gap should be approx. 2-3 mm.
• Re-tighten the fixing handle (20).
• Check the setting before each cut and re-adjust if necessary.
7.6. Adjusting the machine table (15) to 90° (12/13)
• Move the upper blade guide (11) to the top.
• Undo the fixing handles (18).
• Set the angle (d) between the blade (26) and the table (15).
• Turn the setting wheel (19) to tilt the saw table (15) until it is at an angle of exactly 90° to the
blade (26).
• Re-tighten the fixing handle (18).
• Undo the nut (42).
• Adjust the Allen screw (41) until there is contact with the machine frame.
• Re-tighten the nut (42) to fasten the Allen screw (41).

7.7. Blade selection

The blade supplied with the bandsaw is designed for all-purpose use. When you select a blade you
should have regard to the following criteria:
• Use a narrow blade to cut tighter radii than you can with a wider blade.
• Wide blades are used to saw straight cuts. This is particularly important in cutting wood
because the blade has a tendency to follow the grain of the wood and thereby deviate easily
from the cutting line.
• Finely toothed blades provide smoother cuts but are slower than coarse blades.
Caution!
Never use warped or lacerated blades!
Attention!

7.8. Changing the blade (Figure 14)

• Move the blade guide (11) into a position approximately half way between the saw table (15)
and the machine housing (25).
• Undo the fasteners (13) and open the side cover (12).
• Remove the web panel (4).
• Turn the tightening screw (9) anti-clockwise to remove the tension from the blade (26).
