Adjusting the upper blade guide
(11) (Fig. 2/14)
•
Undo the fixing handle (20).
•
Turn the adjustment wheel (19) to
lower the blade guide (11) as close as
possible to the workpiece to be cut (the
gap should be approx. 2-3mm).
•
Re-tighten the fixing handle (20).
•
Check the setting before each cut and
re-adjust if necessary.

top.
•
Undo the fixing handles (18).
•
Set the angle (d) between the blade
(25) and the table (15).
•
Tilt the table (15) by turning it so that
the angle between it and the blade (25)
is precisely 90°.
•
Re-tighten the fixing handles (18).
•
Undo the screw (52) of the pointer of
the dial scale (16), set the pointer to
exactly 0° and tighten the screw (52)
again.
7.8
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.
IMPORTANT:
Never
lacerated blades!
7.9
Replacing the blade (Figure 16)
•
Move the blade guide (11) into a
position
approximately
between
the
machine frame (24).
•
Undo the fasteners (13) and open the
side cover (12).
•
Remove the chain bar (2).
•
Turn the tightening screw (9) anti-
clockwise to remove the tension from
the blade (25).

Remove the blade (25) from the blade
pulleys (7,8) and take out through the
slot in the table (15).
•
Fit the new blade (25), aligned centrally
on the blade pulleys (7,8).
•
The teeth of the blade (25) must point
downwards in the direction of the table.
•
Tension the blade (25) (see 7.2)
•
Close the side cover (12) again.
•
