the teeth touch the guide pins while the blade is
running.
Undo the screws (38).
Move the guide pins (29) towards the blade so
that there is a gap of max. 0.5 mm between the
guide pins (29) and the blade (25). (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.
7.6 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.
2-3 mm).
Re-tighten the fixing handle (20).
Check the setting before each cut and re-adjust
if necessary.
7.7 Adjusting the saw table (15) to 90° (8/15)
Move the upper blade guide (11) to the top.
Undo the fixing handles (18).
Set the angle (d) between the blade (25) and
the table (15).
Tilt the saw 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 use warped or lacerated blades!

7.9 Replacing the blade (Figure 16)
Move the blade guide (11) into a position
approximately half way between the table (15)
and 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.
Mount the web panel (4) again.
7.10 Changing the rubber tires on the blade
pulleys (Fig. 17)
After a certain time the rubber tires (3) 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).
Remove the blade (25) (see 7.7).
Lift the edge of the tire (3) with a small
screwdriver (f) and remove from the blade pulley
(8).
Repeat for the lower blade pulley (7).
Fit the new rubber tire (3), mount the blade (25)
and close the side cover (12) again.
7.11 Changing the table insert (Figure 18)
To prevent increased likelihood of injury the table
insert (17) should be changed whenever it is worn or
damaged.
Dismantle the saw table (15) (see 7.2).
Push out the worn table insert (17).
Fit the replacement table insert by following the
above in reverse.
7.12 Extractor port
The bandsaw is equipped with an 100 mm extractor
socket (6) for extracting sawdust and chips.
7.13 Adjusting the blade speed
(Fig. 28)
The bandsaw can be operated at two blade speeds.
To change the position proceed as follows:
Slacken the drive belt (54) by turning the hand
wheel (4) in an anticlockwise direction.
Move the belt to the desired position on the belt
pulley (55) and the lower blade pulley (7). The
