Undo the Allen screw (40).
Move the mount (49) of the guide pins (29) so
that there is a gap of approx. 1 mm between the
front edge of the guide pins (29) and the gullet of
the blade in front.
Re-tighten the Allen screw (40).
CAUTION! The blade will be rendered useless if
the teeth touch the guide pins while the blade is
running.
Re-tighten the Allen screws (38).
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.
IMPORTANT! After completing the above
adjustments, the upper (10) and lower (34) blade
guards must be refitted.
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 handle (18).
Set the angle 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

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.
Important: Never use warped or
lacerated blades!
7.8. Changing the blade (Figure 14)
Move the blade guide (11) into a position
approximately half way between the table (15)
and the machine frame (25).
Undo the toggle fastener (13) and open the side
cover (12).
Undo the two Allen screws (32) and remove the
blade guard (10) (see Figure 7).
Unscrew and remove the wing nut (4) and
retaining screw (3) (see Figure 5).
Turn the tightening screw (9) anti-clockwise to
remove the tension from the blade (26).
Remove the blade (26) from the blade pulleys
(7,8) and take out through the slot in the table
(15).
Fit the new blade (26), aligned centrally on the
blade pulleys (7,8).
The teeth of the blade (26) must point
down towards the table.
Tension the blade (26) (see 7.2)
Replace the blade guard (10) and close the side
cover (12).
7.9. Changing the rubber tires on the blade pulleys
(Figure 15)
After a certain time the rubber tires (46) on the blade
pulleys (7/8) will get worn by the sharp teeth of the
blades and must be replaced.
Open the side cover (12).
