magnetic catch). Loosen the saw band by turning the

band out of the guides and take it out over the
wheels, see section 7.2 Saw band guide.

direction of the motor. The set of the teeth must be above the recessed diameter (indentation) of the wheels.

 Push up guide with lever (D), position saw band upright by
hand and insert into guides.
 Release lever (D) (automatic working position).
 Tension the saw band using the torque wrench (C) until the
torque wrench clicks.
 Let the machine run for a short time, the saw band will pull
itself to the correct position on the wheels.

 The tooth tips of the saw band are hardened and therefore

important part of the band saw and must be cleaned daily, checked
and replaced in time when worn.
