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.
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 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.
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.
Extractor port
The bandsaw is equipped with an 100mm extractor socket (6) for extracting
sawdust and chips. With the dust collector plug small must be mounted the
protective mesh.
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 blade speeds are indicated on the inside of
the side cover.
Tension the drive belt (54) again by turning the hand wheel (4) in a
clockwise direction.
Important: Drive belts must not be tensioned too much!
