Adjusting Band Saw Blade Tracking; Adjusting The Saw Band Guide; Adjusting Upper Saw Band Guide - Zipper Maschinen ZI-BAS205 Betriebsanleitung

If the tension is too high, the saw band may tear - risk of injury! If the tension is
too low, the driven band saw roller may spin and the band saw blade may stop.
Therefore check the saw band tension before each start-up!
A correct saw blade tension is essential for a long service life of the saw blade and to ensure the
quality of sawing.

Adjusting band saw blade tracking

If the band saw blade tracking does not run properly (centred), the band saw blade tracking
must be readjusted.

Adjusting the saw band guide

Adjust the saw band guide only after the blade tension and the running of the saw
band have been adjusted and checked. Correct adjustment of the saw blade guide
is important. The saw band becomes unusable if the teeth touch the guides while
the saw band is running.

16.5.1 Adjusting upper saw band guide

The upper saw band guide consists of the following components:
 Rear thrust bearing
 Lateral guide discs

Procedure:
 Clamping screw (CS) must be loosened.
 The hand wheel (HW) must be tilted either forwards
or backwards.
- Turn the hand wheel clockwise: the upper wheel is
tilted towards the front door.
- Turn hand wheel counter clockwise: the upper
wheel is tilted backwards.
 Tighten the clamping screw (CS).
 Check the saw blade tracking again.
This procedure may have to be repeated several times
to ensure correct running.
N O T E
The thrust bearing (TB) prevents the saw blade
from being pushed back strongly during the cut.
Procedure:
 To adjust, loosen the clamping screw (CS) and
position the rear thrust bearing (TB) at a
distance of about 0.5 mm from the saw band
back.
 Then tighten the clamping screw (CS) again.
