6.3 Adjust the saw band
Important. The saw band (14) must be at the correct tension before you make any
adjustments to it.
▪ Open the left side cover (15) by unscrewing the sealing screws (16).
▪ Undo the locking screw (11) on the top saw band roller (17) (Fig. 8).
▪ Turn the top saw band roller (17) clockwise (Fig. 1). The saw band (14) must run in the
centre of the saw band rollers (17) (18) (Fig. 12). If this is not the case the angle of the top
saw band roller (17) must be corrected.
In the event that the saw band (14) runs towards the rear of the saw band roller (17) (towards
the machine casing (2)), turn the setting screw (12) anti-clockwise to correct it. As you do this
turn the saw band roller (17) clockwise slowly and continuously to enable you to check the
position of the saw band (14).
In the event that the saw band (14) runs towards the front edge of the saw band roller (17),
turn the setting screw (12) clockwise to correct it. As you do this turn the saw band roller (17)
clockwise slowly and continuously to enable you to check the position of the saw band (14).
After you have adjusted the top saw band roller (17) check the bottom saw band roller (18).
The saw band (14) must run in the centre of this saw band roller (18) as well. If this is not the
case the top saw band roller (17) must be adjusted again.
Please note that adjusting the top saw band roller (17) will not affect the bottom roller (18) until
the saw band has completed several revolutions.
Tighten the lock nut (11) for the top saw band roller (17) again (Fig. 8).
▪ Seal the left side cover (15) and tighten the sealing screws (16) again.
6.4 Adjust the saw band guide
Important. The support and guide bearings must be adjusted each time the saw band is
changed.
6.4.1 Adjust the top support and guide bearing
▪ Open the left side cover (15) by unscrewing the sealing screws (16).
▪ Remove the top front saw band guard (24) by undoing the Philips screws (Fig. 13).
▪ Undo the Allen screws (A) (B) (Fig. 14).
▪ Slide the guide bearing (19) so that the saw band (14) is in the centre of the front and the
rear bearings (Fig. 15).
▪ Tighten the Allen screws again (A) (B) (Fig. 14).
▪ Now undo the screw on the top support bearing (20) (A) using an Allen key (Fig. 15).
▪ Slide the support bearing (20) until it is approximately 1 mm behind the saw band (14).
▪ Tighten the Allen screw again (A) (Fig. 15).
6.4.2 Adjust the bottom support and guide bearing
▪ Open the left side cover (15) by unscrewing the sealing screws (16).
▪ Undo the Allen screw (A) (Fig. 16).
▪ Slide the support and guide bearing (21) so that the saw band (14) is in the centre of the
front and the rear bearings (Fig. 17).
▪ Tighten the Allen screw again (A) (Fig. 16).
Important. The saw band (14) must not touch the bearings when it is idling. Check the
adjustment times.
After you have completed the adjustment work, fit the saw band guard (24) again on the saw
band guide (22) (Fig. 13).
